Any experience with REVO on an A6 BiTDI?

[rassi]

Looking for a proven remap but despite the very good reviews of REVO I struggle to find any for the BiTDI specifically. Anyone on here had it done, and if so, happy with it?

JD Engineering in Holland have done a few biturbos. They have a website with details

Not on the diesel but my twin turbo V8 approves

I've done a bit of research on remap so for the BiTdi, the REVO map doesn't give a massively huge increase. As mentioned above, JD Engineering have had great remap results, but they are in Holland! I'm not driving that far for a remap! Lol
Alternative choice is MRC? I went with a tuning box in the end, as I wanted it reversable for resale.

As I am based in Belgium, having a small journey to JD Engineering in Holland would not be a big deal but I am not looking for max numbers, rather a good overall increase + REVO is half price of the JDE one.

 

[desertstorm]

If you want a remap to give you a performance improvement as stated earlier the Revo remap doesn't seem to offer a big increase. Looks to be about 30-40bhp which on a 310 bhp car is noticeable but isn't going to transform it.
You could have a word with Revo about putting the map on for a trial period. If you aren't happy have it taken off.
It wouldn't be good to have it mapped and then find it's not that much different so maybe you want more performance.

 

[rassi]

I would be slightly worried about the 800-850 nm torque claim of JDE. Thought the safe limit was around 750 nm?

However, the 10 % increase in bhp and torque quoted by REVO is indeed on the moderate side - thanks for the input, some food for thought!

 

[desertstorm]

The Bi-turbo in it's different tunes has between 650 and 700Nm of torque. There has to be more than 50Nm overhead between what a normal car runs and what exceeds the capacity of the gearbox. JD Engineering wouldn't tune the cars if they believed it was going to be an issue for the gearbox. Personally I would be happy to run 800Nm all day.
JD engineering could easily map your car and limit the torque to 800Nm and get 400 bhp out of it.

As you can see you only need 700Nm of torque to make 400bhp at 4000 RPM

Ive been running 385.8 BHP & 773 NM for around 21 months no issues on gearbox so far. Also my remap can be flashed back to factory state when required.

FYI a previous post . http://www.audi-sport.net/xf/threads/bobby-singh-a4-3-0-tdi-build-thread.248899/page-7#post-2843478

I had a conversation with JD a year ago on wether any of the upgrades they conducted had resulted in any known failures on the gearbox side. The answer i got back was no. I didn't ask JD at the time what variant of the ZF 8HP the cars had. I have seen it listed as an ZF 8HP55 before but it obviously can't be if the car produces as in my case over 699 NM stock and the peak power is listed b saudi according to the A7 doc as 700NM on a 313 engine etc etc. See *Note below.

I have also discussed the issue with my tuner and we began to briefly talk about this and the capacity to install and RS6 box but to be honest if I'm going down that route i may as well buy an RS6 in the first place and i am pretty such set on staying diesel i think. Plus there is never any guarantees that it would actually work properly against time and cost spent on it and i don't want to be the guinea pig on that mod etc etc

So it seems clear the gearbox is the weak link in all this and the question remains outstanding on what variant it is and and how high we can push the limit on it without quickly wrecking it.

Jd engineering stage 3 is normally with DPF intact but they have done some with DPF removal with marginal gains over the DPF intact route. However i.e the variance in improvement i can see on their site for stage 3 ranges between 445 - 458 BHP . * Note As a note my car is 313 but dynoed stock at 327 BHP & 699.6 NM. So plus 19 BHP from factory. None of these engines give out the same BHP from what i have observed from the internet they all have some variances. It appears that removing he DPF gives very marginal gains. * See my list of tuning variances below.

At the time i had my car tuned the JD tuning route involved removing the ECU and cracking it open, something i wasn't keen on doing with a 3 month year old £56 k car at the time. My tune which is custom to the car is done via the OBDII port and can be flashed back to factory without detection if required for a dealer visit etc ( so they tell me anyway). Its been to the dealer several times each time being flashed on and off.

I have Superchips on my SQ5, power was taken to 353 and it is a noticeable difference.

My vehicle was used as the development vehicle and they commented that the gearbox was restricting pushing it too much further

I don't think peak bhp is an issue for the gearbox, it's the torque that's going to do any damage. My tuning box is supposed to be running 370atm, but I've not had a chance to verify this figure on a rolling road yet.

 

[snoopy004]

Looking at those quoted figures and claims of 450 + bhp I would say categorically there all pie in the sky Nonsence, Ive recently just had a dpf delete, wagner intercooler and custom air intake done on my 63plate BiTdi and the max oushed out of it was 395bhp with 830Nm of torque. I know tne tuners are very reputable and when I showed themthis they just laughed at it.. I would say if you push 400 your doing very well..

 

[The Black Panther]

Interesting what make is your air intake ? How much did you pay for those upgrades ? My software based only map cost £450 and produced 386 BHP & 773 NM. Anyone is welcome to laugh at anything they wish to it is after all a free world. Check out JD engineering Holland Facebook and webpage they have all the figures there. If they are lying so profusely on their print outs I'm surprised they are in business at all.

After talking for a while on multiple aspects on the tuning of BITDI with JD engineering we got to the gearbox question. They state the box is good for 1000nm and having tuned many BITDI to 450 bhp have yet to have gearbox issues with the highest quoted milage being covered so far at 200k KM.

I don't think peak bhp is an issue for the gearbox, it's the torque that's going to do any damage. My tuning box is supposed to be running 370atm, but I've not had a chance to verify this figure on a rolling road yet.

 

[The Black Panther]

If thats all you got of your upgrades id say there was something very amiss. Check out my figures on my custom map DPF intact and the ability to flash back to stock. These guys regularly tune Rs6, R8, Lambos, AMG etc etc

I took my C7.5 Bitdi for an APR "Stage 1" map, and the figures they quoted was;

320hp>405hp
650nm>750nm

Going back tomorrow to get it on the dyno, so i'll know for sure what its pushing out, 10 days since it was mapped. No other mods on the car.

I'm looking forward to see your RR results! Need to put my car on one sometime.

 

[The Black Panther]

Jd engineering don't look like Mickey mouse tuners. Where did you get your air intake from ?

[snoopy004]

The later bitdi will easily tune to over 400 but fom what im told the earlier ones wont without mods to the turbos. I had the car done at an audi specialist and have no reason to doubt them.. I have to wonder though how long those cars will last running 450. My air intake was made for me

 

[snoopy004]

Also looking at their printouts they are quoting pk BHp at the engine not wheels.. Big differnce

 

[The Black Panther]

Its on a dyno how can they possibly measure PK BHP at the engine ?

[snoopy004]

You will deffo get 405 from your c7.5 as the a slightly differnt platform

 

[The Black Panther]

200k KM so far is the longest one they are aware of. What will any stock car taken to STG3 last its a bit of a non question really none of them were designed to operate at that level.
Can you post a pic of your air intake please ? Is it the original airbox or one from an RS6 modified to fit ?

[snoopy004]

Ehhhh software calculations.. Read their graphs, at the top they clearly state DIN eng hp for engine power and DIN whp-hp for power at the wheels.

Cretin alert. Crack on pal ! Your the expert guide us all

[The Black Panther]

Engine HP vs Wheel HP. What is the difference between hp and whp? The difference is where the power is measured. Engine horsepower is measured at the flywheel, while wheel horsepower is measured at the (wait for it) wheels!

So you spent £3 -4 k on upgrades removed your DPF, Installed a new Intercooler and had a custom airbox made to measure , paid for the labour on that and then paid the tuning shop to MAP your car and achieved 14 bhp more power than my £450 software only flash back to factory and your on here to tell us all how you know everything about theses cars and engines - genius No wonder they told you 400 was max

Looking at those quoted figures and claims of 450 + bhp I would say categorically there all pie in the sky Nonsence, Ive recently just had a dpf delete, wagner intercooler and custom air intake done on my 63plate BiTdi and the max oushed out of it was 395bhp with 830Nm of torque.

[snoopy004]

now im Confused, a minute ago you just asked how can they measure it, now your an expert .lol.. Read the graphs its there in black and white.. And no they havnt measured that directly at the flywheel, the software calculates it from the power at the wheels..

 

[snoopy004]

3-4k???? You a mind reader now too?... I spent no where close

 

[snoopy004]

Theres no need to start calling names and being childish is there?

 

[The Black Panther]

Jd engineering are 3995 euros and that without removing a DPF. Who did this stuff for you and how much did it cost ?

3-4k???? You a mind reader now too?... I spent no where close

 

[snoopy004]

So loking at your graph, your fist stock run is 345 which is probably measured engine power and your final is 385 which is probably engine again.. So really your chucking out about 350 at tne wheels

 

[The Black Panther]

I guess not . Heed thine own words. Opening statements like the one below kinda leave you open ........ Scott
