I was kidding when i said you can drive down. In case of remaps, it depends on how hard the ecu is to remap. In the Ecosport thread, one of our own member has put up a detailed thread on the remap process.

This is how it generally works:
1. The tuner first understands your requirement. What is the pain point, where would you like the power to improve, etc etc.
2. He would then extract the stock map from your car and make the changes as necessitated in the map.
3. Load the map and drive for around 40-50kms for the new map to take effect.
4. Check if it matches your criteria. If not, the tuner will sit with you when you drive and check where he needs to make changes to the map. Based on this he will make changes and reload the map.
5. Test again and once you are fully happy with it you are free to enjoy the car.

Experts or people who have got the remap done can chip in with their inputs too or correct the above process if any. For remaps, some of the tuners like T-o-T have tie up with people in different cities. So they will remotely get the remap done on the car though they may not be present in your city. Some even travel all over on a set schedule and do the tuning. You might want to call and check with the different tuners and go with the one whom you feel most confident about.

Lightbulb What is Engine / ECU Remapping ?

While visiting a reputed tuning garage at Cochin with my friends Polo GT 1.6 TDi, they claimed to improve the performance of the car from 105 Bhp to 145 Bhp by remapping the engine. We left to another tuning and car accessories garage where the guy claimed that it is impossible to improve the bhp to 145 just by remapping. His theory went like this:

Quote:
Most car manufactures tune the engine for maximum reliability and longer life, and hence they always leave a reserve power of around 30% which will be used only in case of situations which demand more power, like if they the car is carrying more load than recommended, or one of the wheels is punctured etc. So, by remapping, we can utilise the extra reserved power all the time, regardless of whether it is required or not. But, this will increase the stress on the engine and hence decrease its life. So, the maximum power that can be gained by remapping is 30% for Polo and hence a theoretical max. power would be 136.5 Bhp, which will not be attained in real world situations.

Although many claim to have increased power to 145 Bhp, it is not proven!
We are having second thoughts now!
  1. What is the actual process of engine remapping ?
  2. Does it decrease the life / reliability of engine ?
  3. To what extent does it improve performance ?
  4. Are these performance figures claimed by tuning garages true ?

You can extract 145 bhp from the 1.6 TDI sure with just a remap, its no biggie.

Some parameters like CRDI rail pressure, injector pulse width, fuel pump pressure, drivers wish map, Boost (If it has an electronic boost controler) etc etc are changed.

You will need to take the tune to a dyno to ascertain flat spots if any and iron them out or if the tuner has already done all that for your model of the car and ironed everything out, then its just a matter of half an hour before you are good to go with the new tune.

But remember, at the end of the day, its your car and more power is never free. Injectors will be a little more stressed, so will be the fuel rail and crdi pump. I don't know their FOS and how close you will get to them. but one thing is sure, the EGT ( Exhaust gas temperature) is something that will need to be kept a watch on if you are into revving the car or top speeding a lot.

Also can your gearbox handle this much increase in torque and bhp is a question you need an answer for.

If you personally ask me, enjoy the 105 bhp and XX amount your torque your car already has.

Cool Code 6 Tuning

Some of you are aware that i have picked up a Thar, after coming from the silky DDiS Swift, Thar's Crde engine felt... well.. LIKE A TRACTOR! I was ok with the power, for the weight of the vehicle it moves pretty well, BUT it was like those Volvo buses. No not the handling, my vehicle has Tein shocks all around, which makes it predictable in handling department, but the Rev range. It was pathetic! Usable from say 1800 to about 3000 beyond which it is absolute waste to use the right foot. So one keeps shifting up and down in that narrow rev band. Second issue, it feels very restricted and rough (tractor reference), does not like the idea of revving.

I was in dilemma on what to do. Then came info that Code 6 tuning has done a map for Thar and is a riot. The said vehicle is running on 31" offroad tyres and belongs to a good friend, test drove and i was mighty impressed the way in which the vehicle was moving.

Fixed up appointment for today morning with Code 6 and met up with Sajan at their outfit Bay 6. Ecu came off the vehicle in about 5 minutes and was handed over to Sajan, who had to struggle a bit to open it up (being holiday no helping hands). The parts inside are delicate and one minor slip is all that is enough to mess up the ECU, so Sajan patiently goes around the ECU mm by mm to open it.

My original plan was to go for a stage 1 and get the rev issue sorted, but then Sajan insisted that i try his latest brew (let us call it Stage 2). He went on with his job of carefully loading the new map after taking backup of the OE code.

Put the ECU back, a test crank and engine fired up as usual. Since its stage 2 he insisted that we get the EGR cancelled and remove the cat con can. So the mech took another 30 mts to get this done and we (Sajan in front and Vidyut in back) again started the vehicle and took it out for a test drive.

First gear and wooooaaahhh vehicle just leaps forward and unlike earlier just keeps revving, it was already 4000+ rpm and with a blink of an eye. I see a huge burst of black smoke hmmm. Sajan assured me just keep driving, so we went on and every time i give gas i see a plume of smoke and vehicle just keeps climbing revs like a rabid locomotive. ECU needs to learn parameters since such advanced stage means all the historical data is also wiped clean. Pulled over to restart the engine, yes that is also needed. And drove back..

That is when i noticed, the smoke has disappeared and the acceleration is still ON!

Was in a hurry so said bye to Sajan and hit the Sarjapur to Indira Nagar via IRR, and i was grinnning from ear to ear every time i gave gas. Apart from EGR and Catcon this is stock, no air filter or exhaust mod. But the way in which the vehicle now revs and puts on power is just awesome. Mind you i have driven Thar's with tuning box and Scorpios. But Trust me, the ECU remap and a Piggy back SHOULD NOT be compared! Unlike feeding more fuel, a proper remap just creates a whole new possibility with even a not so modern diesel engine. And as i said this is just a moderate tune, considering the vehicle dynamics of Thar, it is better to be safe than sorry.

Yes more is possible! to Code 6 Tuning.

EDIT: My Thar runs on 28.5" tyres so acceleration is also much more brutal compared to the previous vehicle i drove.

.
The remap seems a simple enough mod which makes a world of difference in drivability especially in a not-so-advanced engine like the Thar's.

That said, I wonder why dont manufacturers offer something optimal as these maps from factory?By optimal I mean optimal, as in something with reserve left and not maxing out.

I've heard good remaps don't affect fuel efficiency either and in some cases improve it.Any cues?

I am sure it will improve in my case since drivability is so much better. Vehicle can pull in 4th gear as low as 35 Kmph with a gentle foot. Infact mild inputs in moderate moving traffic Thar is now an automatic with no need to shift.

Default Re: Tuning Box versus Remaps (Diesel tuning)

I have a VW Polo TDI (2011) Model which is a 1.2 l engine.

The main problem i have is with the drivability as it does provide enough torque. It does not pull enough at low rpm and i have to constantly shift gears. For eg. If i am at 30 kmph speed i have to come back to 2nd gear to pull it instead of staying on 4th and cruise it from there.

So my question is that can a chip tuning or mod box /remapping help me here? And which is the best place for it? I am from chandigarh by the way so nearby places will help too. Thanks.

Default My Engine Remap Experience With Sx4 & Grand I10

July 2015 Petes remap
My SX4 diesel had clocked 80k kms and I got the Remap itch. I decided to go with Petes remap since Petes is a well known name. Remap costed 28k and power gain was quoted as 110bhp and 245nm.There was wheel spin even in 2 nd gear and turbo kick was more addictive. I loved the remap initially. Same day, I had to drive back 400 kms to mangalore from cochin at night. This drive made me hate the remap. I noticed flat spots in map and huge pile of smoke above 3k rpm. Also fuel efficiency dropped by 2 kmpl. I started missing my stock map. I had to schedule a drive back to cochin for stock map which I couldn't. I drove for 2000 kms more and noticed low oil pressure warning light. Maruti service advisor asked me to do engine overhaul. I cross checked the same with my FNG mechanic and only piston rings and engine head service was done. I dont know if remap was the culprit. Post repair, I used to drive car very safely. Finally after driving 5k kms I got my stock map. Engine oil consumption was nothing significant after piston rings change.

January 2016 Wolf moto remap
I had run 93k kms in my SX4. I did not face any oil consumption or mileage drop issues. But my car used to smoke a little even in stock map now. I read about switchable maps from Wolf and wanted to try the same. I drove again to Kochi for remap. Wolf tuner read my stock map and he was surprised to find out that it a 512 kb file. This is the first time he saw 512 kb file in 90 hp multijet engine. He had not remapped any sx4 before, but did a lot of lineas and puntos which has same engine. He told switchable maps requires ECU recoding and it would take time. I had to get back to mangalore. So we decided to go for a normal remap and I was promised switchable maps in future. Rajiv, the tuner started the work on remap. He told he is not going to change fuel pressure, injection cycles etc. He increased turbo boost pressure to 2600 mbar, made mild changes to SOI(start of injection) and increased fuel by 8 percent. He flashed the new map and we go for a drive. I missed the wheel spin, addictive turbo kick of Petes remap. I could feel only mild increase in low end. I started revving above 2500 rpm and car was picking speed all the way to 4000 rpm. Power delivery is very prominent in 5 th gear. I shift to 5 th gear at 2500 rpm and push the pedal, Car picks up speed very well all the way to 4000 rpm.In stock map power used to taper above 3000 rpm and now it is increasing. I was happy with the remap. But there was black smoke above 3k rpm. Rajiv will correct it and fine tune when he flashes switchable maps in future. There were no flat spots and linear power delivery in turbo zone. I enjoyed my drive back to mangalore. I have driven 5000 kms post Wolf remap with absolutely no issues except black smoke under hard acceleration. I would be getting switchable maps soon from Rajiv. Excited!!

November 2015 Code 6 remap for Grand i10
My Grand i10 had clocked 50k kms and I wanted to remap. I did not want to go back to Petes and I did not know about Wolf moto. I contacted code 6 and Tune O Tronics. I decided to go for Code 6 since the price quote was lesser. I drove to their bangalore workshop and remap process was initiated. Tuner told 90 bhp 200 nm would be ideal and he can give 100 bhp 220 nm with few precautions. I asked for the more powerful map and he worked on it and Flashed. I was very excited to feel 100 horses. We go for a drive. I start the car and accelerate.. No difference. Shift to 2 nd and accelerate.. May be there is slight difference. Shift to 3 rd and ya there is mild increased. Noticed mild increase even in 4 th and 5 th. But I was quoted 100 bhp and mild difference, I was not at all happy. Tuner did some changes to map and still I couldn't appreciate power gain. What I noticed was huge amount of Black smoke. I decided to get back stock map and work on remap at later date. Tuner had said Grand i10 is VGT, but I think it's a FGT. Guess the remap methods are different for FGT and VGT equipped cars.

Code 6 experience was before I got my SX4 Wolfed. I asked Rajiv about grand i10 and he said he has not done remap on grand i10 and could try. I am still confused about grand i10.I have asked for demo of diesel tronic tuning box in Grand i10. If am not happy with the box, I will try working it out again with Code 6 or else catch up with Rajiv at Kochi.

I will list down few Points I learnt from interaction with various tuners.
1.Tuning box basically deals with fuel rail pressure or injection modulation. Diesel tronic dual channel deals with boost pressure too. All sensors have voltage range of 0-5 volts. Tuning box alters these values and fool the ecu to inject more fuel.
2.ECU Remap. Power gain is possible with a remap in many ways. There are a lot of parameters to play around with. Fuel rail pressure, injection duty cycle, SOI, Torque limiters, Drivers wish map, smoke map, Turbo boost pressure etc etc can be altered. So with a remap, power delivery is any day better than tuning box.
3.About Petes remap. Petes has tie up with many international tuners. Drawback is you can't sit with your tuner and make him tailor the map for you. Also Petes is good for VAG cars since they get the remap done from Custom Code. I dont know about the Petes remap for other manufacturers.
4.Switchable ECU REMAP. Wolf moto is the only tuner in India who offers switchable maps for fiat multijet, Fiat T jet, Renault dci engines at same or even lesser cost than normal remap of other tuners. Few tuners do have option of switchable maps using a obd flasher which would cost around 30 K plus remap price.

I will post more details as I clock more miles in My Sx4 and after I get switchable maps from Wolf.

Default Re: Tuning Box versus Remaps (Diesel tuning)

I have confirmed turbo charger in Grand i10 is FGT. I will attach the picture of Turbo. There is no electronic solenoid like VGT and there is a wastegate actuator with pressure pipe(blue colour) going back to turbo compressor. Code 6 tuner was adamant that Grand i10 turbo is VGT. He claimed to have increased the turbo boost and only my turbo charger would be at risk if I do high speed runs for long time. It is not possible to increase boost of FGT without ECU control by remap. A manual boost controller is required. Since the remap was done thinking increased boost with other parameters change would help, entire tune went wrong. There would be no effect if you increase the boost in a map for cars with FGT without ECU control. Code 6 has many happy remapped customers. Grand i10 is a rare sight in any tuners garage. But I expected the tuner to do his home work well and atleast to differentiate between VGT and FGT turbo.


I have driven almost 400 kms with RD box now. Power delivery increases after driving few kms in every mode, thanks to self adaptation technology. P2 mode is really insane. It totally transforms my Grand i10. I find black smoke under hard acceleration only in P2 mode. I will take a call on buying the box after checking mileage.
Cheers

Post Re: Tuning Box versus Remaps (Diesel tuning)

Hi BHP-ians,
I have been looking to Power Up my New Scorpio for quite some time but was confused on the same (Tuning Box or a Map)
Finally after Extensive research and reviews it was evident that a map is better than the tuning box anyday, as very rightly pointed out by some BHP-ians.
Next Step was choosing the Tuner.
Since I am from Kolkata there is No viable option for a remap here.
Kiirus usually visits Kolkata on their own time, when they have more than 5 cars lined up.
Next I contacted Pete's (Sent mail and Called) NO reply from them.
Next in Line was Red Rooster. They replied back within a day saying that remapping of the New Scorpio has not been tried and suggested me a Tuning Box.
So slowly all these options Checked out.
Then I contacted CODE6 , Sajan was very patient in hearing out my requirements and said the same that it hasn't been tried and he will have to create the map of his own which involves certain risks regarding reliability.
So i agreed to take on the risk and fixed an appointment . I drove down to Bangalore in June with around 25k on the ODO.
The ECU was opened Very Carefully, being a Precision operation.
Then it was connected to the Laptop and voila,remapping was in progress.
I needed a Moderate Map with a Power Boost and No Effect on the present Kmpl with the EGR, Rev Limiter Off.
Took some hours to create the map and the ECU was back connected with the car.
Initial Test rounds were taken in the Bangalore city itself , which wasn't very Co-Operative considering the severe traffic conditions. But my beast was Accelerating like crazy which needed some tweaks in my driving style.
Due to the Time constraint I didn't get a chance for a Dyno test but the Torque was connected to the ECU which gave some very satisfying Initial Stats.

Tuning Box versus Remaps (Diesel tuning)-stats-initial.jpg

Then I drove the Car from Bangalore~Goa~Hyderabad~Kolkata.
The Power on tap is very satisfying and its now much more of a pleasure to drive. Since the engine needed some time to learn the new parameters and get used to the new map, I gave another 10k Kms before i performed another test. Currently my ODO reads around 34K kms and I did another test on the Highway by almost redlining till 4th Gear and finally 5th for cruising. Attached Screenshots of the Latest Test results from Torque PRO.

Tuning Box versus Remaps (Diesel tuning)-14233616_10153963670725838_339933355_o.jpg

So Now, Here I am, Very Satisfied every time I Crank the Engine and Press the accelerator driving one of the Most Powerful Scorpio with a Smile.
