How do you test for Reliability?

5. Diesel owners- You cant ask for more!!!

A piggyback ECU meaning it sits in addition to the Stock ECU and fools the ECU in tweaking some settings! thereby giving us MORE POWER!

@Mpower - The CD0801-PF is an add-on piggyback ECU.

Thanks Karthik, awaiting the Dyno tests with the curves! oops the torque and power curves!

Thank you sir for your kind information!

rdkarthik, I browsed through your website but couldn't find any info on the diesel tuning box or the costs. Could you PM the costs to me?

Thanks.

Waiting for more updates..

ECU for Cedia? How much gains can be expected out of it?

I wanted to put a note to after reading your thought on adding the petes tuning box for your DDiS. wy dont you just have it reflashed with a new tuning program. I had it done on my swift and its really amazing. I am yet to find another DDis that as quick as this and whats best is i still have my warranty since there are no hardware mods....yipee....look up the tuners sections and see kiirus ecu tuners in the mumbai area

Any possibility of quoting an estimate for this?
How do you compare the performance against PETE'S box for DDIS?
Any timing recorded?
Change is top speed?


On the fly settings seem so cool.waiting for further reports

I thought ECU constantly adjust themselves to the driving style of the driver. Especially the new ECUs that have been put into Swift DDIS. If my statement is correct then any remappping will be reset in a matter of few hundred kms. If my statement is not correct then after every ECU reset why is that we are asked to drive cautiously for next 10-20 km.

Can someone throw some light on this topic.

Remapping changes the fixed mapping ratios in the ECU. The ECU does not change this data. If the ECU actually adjusted its own A/F parameters... well, what are tuners for? How can engines be tuned aggressively in one car and sedately in another? It is allowed some leeway on some of the parameters the tuner/manufacturer sets in accordance with the driving style or environment it is working in.

The reason people ask you drive cautiously is so that the ECU adjusts itself for a sedate driving style, thereby giving you max mileage, the Golden Rule in India. Drive hard after a reset and the ECU will adjust itself for it. The ECU does not continually learn except for when the knock sensors tell it that the engine is about to explode unless it does something. It learns for a few KMs.

i want i want i want a rd ecu for my palio 1.6.. then i want turbo...

karthik, anyway i can convince you to make some time for me buddy? (I'm a 'newbie' by tbhp standards, but i read tbhp forums all day most days )

+1 to that. BTW, how many people remap ECUs in India?

Hope that was not a rhetorical question
4 that we have heard of on the forum itself.
Pete's(mostly skodas)
Kiirus
Rdkarthik(piggyback ecus for common rail diesels)
tuned i chips- (zakie-mainly petrols right?)

Maybe more, but have not heard of them.

@ Rippergeo:

Hi, my "+1 to that" was in response to Immortalz's explanation of the ECU.

My second question was how many actually re-flash ECUs in India? And who are the guys who do it?

Significant, from personal experience. You can ask Torqueguru.

The costs range between 19-24k, from what I understand. There are various modes and models.

@rdkarthik

Any updates sir ji ?

[rdkarthik]

Hi All, sorry about the delayed replies.. We did a couple of V-BOX runs on a stock swift diesel with the XM400 ECU on it, riding on 205/15s and two people on board. Same driver and same testing strip.

Air Temp - 28deg,
Altitude - 3100 feet above mean sea level

As you can see, we were shifting at slightly higher RPMs with the performance map as it was making much more power out there than stock, any higher we revved on the stock ECU resulted in slower stock 0-100s, so this is among the good runs.

Thats a drop of ~ 3.8 secs from 0-100 kmph. Thats impressive Rahul (hope you got the joke ) .
