Tuning Box versus Remaps (Diesel tuning)

[air870]

just thought i might share my sequence of mods on my Tdi. i started out with a P-Box tuning box, then added PP520 injector nozzels, did a EGR delete and the adaptation for more air, removed the tuning box as my fueling was being taken care of by the nozzels and went in for a Jeff Robertson[ rocket chip] stage 2 remap[ it required my ECU to be mailed to him in Redlion PA. Soon that was not enough, so out went the PP520 and in went a set of PP764s and a RC6 tune accompanied by a VNT17/22 hybrid turbo,2.5 ' passenger performance SS downpipe,boost factory SMIC with a perma cool fan behind it,southbend stage2 clutch and a intank lift pump from the PD.

i had earlier also put in ARP head studs which were good for upto 21psi but now i ve started to have a prob with 28psi and am going back to the original bolts.More stuff in the pipeline. will update when done. as far as this thread is concerned. i ve found much better performance from my remaps as compared to the tuning box and fortunatly have not experienced any ill effects.

That's some very nice stuff. Have heard great things about the clutch especially. How are you controlling the VNAT? BTW chances are that turbo is manufactured in India.

the VNT is ECU controlled, i had to specify the exact mods for jeff to load on the appropriate tune. forgot to add earlier that a 3bar map was also added. unfortunately the VNT 17/22 is a hybrid, i.e. a non standard Garrett and unlikely to be available here.

Great Choice of mods there. I see that you have removed the EGR valve, did you get any " check engine light " intitially before adding the chip ?
Am sure the chip you have added must have taken care of this.

Where did you get the mods done from?

1.9tdi has a stronger gearbox and that's where there is no limitation to mods one can do. However I guess adding a FMIC with slightly bigger intake piping would also help considerably. Did you get the SS downpipe custom made here?
Another thing that you can consider and am sure you must have thought of is adding high flow manifold both for exhaust and intake. This does make a considerable difference.

Unfortunately I have 1.4TDI fabia. Where can't do much of mods due to the limitation of the gear box However am planning to get a custom made SS downpipe with decat. Thought of removing the EGR valve too but it would leave the engine check light on unless the error could be deleted completely.

A lot many turbos and tuning parts are avialable for a 1.9tdi, no wonder one can do so much with this engine. here's a site which has almost all Drop in Turbo upgrades and replacements

All the turbo used in VW/skoda tdi engine are the borg warner,KKK turbo or the garrett. The hybrids are based on the garrett turbo none which is made here in India.

[1]the clutch is the prob with the extra torque generated, so the choice of clutch kits depends on the estimated torque after the remap,i earli.[2]An FMIC wold be too complicated because of the piping hence the larger sized Boost Factory SMIC,[3] the down pipe is made by Passenger Performance 2.5 inches,[4] my PD130 Passat larger intake manifold will be installed by this month end but am not changeing the exhaust one as the cast iron one that came with the VNT hybrid is matched to it . for your fabia, i suggest you check out{ http://briskoda.net/forums/,http://www.seatcupra.net},if you get a remap done be sure to specify a EGR delete CEL delete.FYI deleting the EGR and the accompaning adaptation setting will ensure a clean sootfree manifold .Most of my info is from Tdiclub.com, some serious gurus there. But all these parts and info would just be worthless if not for Ash[ my tuner/friend].

Which dealer?

.......
Any updates on your box performance, Ravv?

In the price range for me the options seem to be Kiirus 22K remap vs Pete 31.2K tuning box. MTM drove me away on pricing, Kiirus offer ends on March 31st. Am seriously not able to decide on either. Also ,am quite surprised to see no better pricing even in such a market situation.

Any other tuners that I should consider?

HELP needed.

Hi ACM, Sorry about taking so long to reply to your queries.

I was trying to track down the part no. for the spoiler. It is Part no.: FAA610003. This is the one that is a flat srip that sits right on the boot edge and sticks to it end to end. The other one is called a vRS style spoiler. There is only one dealer for Skoda in Hyderabad - Mahavir Motors.
The spoiler cost me Rs.8881/- all inclusive. I paid the whole amount after the spoiler was fitted.

The Pete's box has added to the joy of driving. The car now has 'real grunt' in the low and mid revs. One issue was the black smoke but this was resolved after shifting to Green Cotton filter (stock replacement). There is no drop in FE as far as I could make out, let me check it out over a few tank-fulls.

I understand that there are a few remapped Skodas in Hyderabad which come to the dealer. The mechanics told me that re-maps give rise to problems in the electrical/electronic systems. The workshop is used to Pete's boxes and tell me that the Pete's boxes cause no problems.

Cheers,

I don't know in what context is he saying that they give electrical problems. I have been using a remap since last 21000kms and not faced any issue as yet. There are many options available for remaps depends which one does what. I have had custom code, and not faced any issue.
Recently I made just changes to my intake system with customized 3 inch intake and green storm filter, upgraded the downpipe and removed the cat. Must say the car has become more lively. Zero turbo lag. Feels like a petrol car now. It just shoots to 140. I can say the difference is atleast 15% or so.

Good to know that you enjoying your new added power. If driven in a sedate manner you will definately notice increase in mileage. But, don't forget to clean the filter every 2500kms for optimum result. As it gets choked pretty early which means it works at its best what filters are meant to do, filtration.

Cheers!

hey guys,
need help on deciding whether to go for a remap or install a box on my Octavia 1.9TDI thats already clocked 78k.

I have had a remapped Octavia since the past 3-4 years. It is absolutely amazing & runs fine in every aspect. This was a Pete's remap, the car was around 25k on the odo & is now at around 55k......


Go for it !!



Cheers

thanks mate, however a couple of questions.

1. what happens to the remap when i send my octavia for a regular service and they run the diagnostics. warranty is not an issue since i have clocked 75k already. do i lose the remap?

2. would i need to strengthen the internals, upgrade the injectors, add a higher performance air filter, etc to support the increase in power and torque?

cheers.

The Skoda guys would not worry if it runs a different map. So far I have never been questioned whenever it went for service. So I am guessing they did not figure out. No you will not loose the map unless they re-write the ECU, no reason anyone would.

You need not do anything to the internals if you stay with stage one. You should put a stock replacement Green Cotton or K&N air filter.



Cheers

I dont know whether this will help. Please check the pdf of Swift diesels(Re-tuned) and tested by Autocar. Unichip seems to be very good if you want more like a stock car with improved smoothness and power.

I am planning to buy a used diesel hatchback. I have shortlisted Punto and Figo currently. I plan to either install a tuning box or get an engine remap done.

I have heard that engine remapping is done well at autopsyche. Do you still recommend a tuning box over a remap for the above mentioned cars?

Also, what are the other good diesel hatchbacks which respond well to remap/tuning box?

[headers]

A tuning box cheats the ecu and injector pressures are higher than normal.

A remap is a complete package
