Remapped...

[SimonH]

Jason,
How long did the re-map take?.Where abouts is the ECU on the car, and are the tamperproof fixings readily available?.Did Minhea say how long it might be, before being able to flash the ECU by the OBD?.Sorry for the questions, but this sounds exciting,if a little worrying, with the ECU being prised apart.Sounds a bit like the old Cosworth days, with the EPROM chips. Keep us informed with your opinions, we are really interested.Has anyone done big mileage with a good re-map, regarding reliability.Regards, SIMON.

Great write-up. It is now becoming tempting to go for a full miltek with downpipes and 200-cell cats, assuming the above can be taken advantage of by MRC in the remap.

Simon,

Mine took a little longer than normal as one of my ECU's overheating and not taking the map, the 're-map' bit is quite quick, its the testing before after and during that takes the time.. should take around 2 hours, I was more like 4

The ECU's are situated roughly at the base of the windscreen in the engine bay obviously..

Yes the replacement security bolts are readily available

OBDII is available, just not via MRC at the moment, if there is enough interest in B7 RS4's they will buy the cable that only works on these cars, its bloody expensive to buy if they are not going to use it

The current map should be within tolerances for long term usage, its not 'taking it to the max' having said that Minhea did say if you are hitting the new rev limiter in every gear every day you might have some longer term problems

Hope that helps...

Great info and an excellent write up Jason.
Data logging is an excellent way to tune, and seems like you got a good price for the effort MRC put into it.

Thanks... It really felt that if Minhea was not happy he would not have carried on, he spent alot of time on my car and said at the begining if I was not happy with the results he would put it back to stock for me and not charge me anything..

I have vagcom, but a very novice user, I am hoping to do some of my own data logging at some point to keep an eye on the performance of the car and any fault codes that may crop up, not expecting any, but nice to keep an eye on things... could do with someone running a vagcom training day

Thanks for that Jason,
So, do you feel that the car starts to pull far sooner than before?.If i try to explain the standard performance to my friends, i say that the initial pull is very good, then it goes slightly flat around 3.5k to around 5.5k, then pulls like a train.If the car started to pull far earlier down the rev range, say 3k, like it does at 5.5k, it would be a monster.Do you think the car is a little more like this now, if you can understand my confusing assesment?.Regards, SIMON.

Respectfully placed smiley coming up......... so not to offend anyone.

I know Miltek have sports cats but are they making de-cats as yet?

On the original posting on the group buy for our friends in S'ton wasn't there something regarding a Miltek equipt car that had problems running lean and hot due to the re-map and lack of cats? Maybe my memory serves me wrong.

And before anyone kicks in, I am being serious.

The Miltek car was running lean before the ecu flash and after. It was only slightly on the lean side.Nothing to do with DMS

Please don't get me wrong, I am not and repeat that, NOT knocking anyone. It was a comment regarding the addition of the Milteks and what it may or may not do regarding the maps. Miltek have a MASSIVE presense and know everything there is to do with what can and can'tbe achieved by better breating, however I just remembered that comment and was looking into why.

When Mihnea mapped my car he talked about the exhaust, cats and filters with some knowledge.

Again maybe Mihnea would place a comment here?

BTW, Jason's write up is spot on, top report.

Simon,

The power comes in much earlier, its more like 2.5-3 I noticed yesterday after writing... once in it now stays all the way to the red... I was experiencing what you were, I felt like I really had to 'wind the car' up to acheive peak performance, not what I thought the RS4 would need, it does not now, its all under your foot all the time a much more consistent drive.. I bet if you have sport on it does not do that... its the map that Audi use to create almost a placebo effect with the sport button by reducing the throttle up to 5.5k revs in non sport mode.. crazy

in roughly layman terms, how do these maps INCREASE mpg?

Need to ask one of the tuners that one... my only guess would be that you are not 'flooring' it as much to exctract power, therefore less fuel is used... although I would have thought the map would use more fuel not less.. sorry not sure

[S4INT]

I believe it's down to there being more torque available for less throttle opening, or something like that!

[Adam]

kind of makes you wonder why Audi don't make it like this out of the box if the power increases are modest and therefore don't compromise their tolerances - anything that helps mpg would be of benefit to the RS4!

Correct, it was decided that a re-map was not a good idea until the Milltek issue was sorted.

I've also been told on several occasions that the B7 RS4 does have issues with the frontal part of a Milltek system (not sure if that's sport cats or de-cat), as the car throws up emission warnings & as such starts running anywhere between very & slightly lean. Hence why i'm steering clear of a full system & just going the car-back route.

IIRC, the car that was failing at DMS, was running very lean, although not quite to the point of being dangerous, but defo something that needed looking at sooner rather than later. I could of course have mis-understood.

I don't think anyone is saying you're knocking anyone. The issue on that particular car during the Group Buy, was nothing to do with DMS & if that car had been at MRC, the results would no doubt have been the same. Problem was purely with the Exhaust & it's more likely it was a fitting issue (dealer fitted i think) rather than Milltek themselves.

That said i'm steering well clear of a full system as i keep hearing about emission issues & thus the cars running lean. I guess this si the car protecting itself. Not a tuner issue regardless & as said, DMS suggested the owner sort out the Milltek before considering any re-map.

Seconded, in stock form the car is of course quick & a power band can be felt upwards of 5500RPM. With a decent re-map, that extra power/torque that you feel from 5500RPM is now right across the rev-range, coming in with slightly less force but much lower down the rev-range & yet their is still a surge from 5500 as before The additional power/torque is also felt right up to the new redline at 8400RPM.

Sorry, questions from a Novice on re-mapping:

What did your insurance company say about this, Did you tell them?

Re-Map, What about warranty?
