Remap, not from MRC/Unit 20 etc...

[coldo]

I've done some research and think I already know the answer but would like to get peoples opinions.


A local (well known and proven) tuner is offering a '£200 remap in May', including before and after power runs... this is enough to get me interested. However... he is a very good tuner with a host of high performance high profile cars having been built by him and his guys - but none of them Audi RS's.

I understand MRC(for example) have developed their stage 2 map, tried and tested it etc.. So what can I expect from a map by a guy who knows what he is doing, but not to the level of a 'specialist' similar to the guys i've mentioned in the subject?

I believe the main benefits could come in him playing with the torque limiters? Maybe a few BHP?

Any opinions welcome. (My car is otherwise standard bar exhaust flap vacuum blanked)

A tuner with no experience of tuning an RS4, or an Audi specialist with lots of RS4 experience who creates a tune specific to your car?

I know which I would go for, every time... experience.

I'm not saying no experience, i'm sure he's capable, RS4 will be low rent to what he often works on.

It's more the case of what can MRC do, that this chap can't? i.e. am I wasting £200? Will it be pointless?

You need to have indepth knowledge frankly of the RS4 V8 to get not just power, but NM's, smoothness and things like cold start delete are just things that make the MRC map.

In answer to your question what can you expect? Me, you and the tuner has no idea what results will be achieved. They have no experience of the engine so no delta to spring from...

Without the pre cat delete, and Carbon Clean, you are on a bit of a hiding to nowhere...

Me? I'd go spend £200 in Spearmint Rhino - you'd have more of a lasting memory...

I've had a number of maps on my two RS4 B7's from well know and independent experienced tuners. So by a long margin Dougs map is the best.

[Regy53]

my old car had a remap from another company and had also had work done by said company. AMD.

I took the car to MRC to have some work done, anyway cut a long story short the remap amd had done was toosh, So much so when flashed back to standard it made more power.

The morel of the story for me is, take it somewhere or to someone who knows there onions, and in this case onions is rs4's.

Also tune from a healthy car making the power it should from the start

Neither did I, I said no experience of an RS4 - which is what you said yourself

but none of them Audi RS's

I'm sure he's capable, RS4 will be low rent to what he often works on.

It doesn't matter that he works on exotica, he doesn't have experience of this engine and this installation. Just because he can tune a Ferrari V12 (for example) that's no indication of his ability to make a good tune for this engine - every engine and every installation is different - that's what the Engine Management experts at the sports car manufacturer I used to work for told me, and I agree with them.

It's more the case of what can MRC do, that this chap can't? i.e. am I wasting £200? Will it be pointless?

MRC have hundreds of satisfied customers, some of whom (as in previous posts) found that other tuners just didn't have the experience and knowledge needed to make more power, more torque, more drivability from this engine - THAT'S what MRC can do.

Would it be £200 wasted? Possibly, as the saying goes "you're tried the rest now come to the best" which when it comes to tuning RS4s is what MRC are - in the UK.

[SuprSi]

Thing is MRC's maps have been developed and refined by mapping thousands of cars. He knows every quirk with the rs models, the best way to make power and keep drivability good.

Think of it this way. Even Doug at MRC, if he'd never tuned an rs4 before he could probably get a rough map done in an hour or two, which is what this other fella is going to do. But to get the map as refined as an mrc map they would need a lot of time on the rollers and road testing. Probably a case of days rather than hours.

[MikeFish]

For me it's not even about the power or torque gains, I see these as minimal (although they DO go up where some tuners maps can go down). It's about knowing which features of the OEM map need tweaking or changing; increasing the cold rev limit oil temp from 60 degrees to 70 degrees due to the increased warm rev limit, removing the cold start feature if required, full torque in the lower gears and the most important one for me; setting the perfect accelerator response curve in sport mode so it feels like it is pulling like a train but not too jerky when coming off and off the throttle.
The other important benefit to me is their knowledge of what the car should be producing in any state of carbon build up or mods and therefore can easily detect and in most cases, fix, any problems like vac leaks. Unlikely an unexperienced RS4 tuner will detect / fix a problem as well as MRC can.

[Tile Diver]

I think I'd need a very good reason to go anywhere else for a re-map, and I can't really thing of one!

MRC done me proud!!

[coldo]

Point taken!

I'll get it to MRC instead

[Bladerider]

I wouldn't bother at all.

If you have a virtually stock RS4 then there is very little point changing the map as that wont be the likely restriction to any real gains.

Best save your money for a later day when you can get a bunch of things done and then get a map suited to all those other mod to make a cumulative gain.

Biggest likely issue being a carbon clean for example.

Have to disagree there.

Doug at MRC reckons that a carbon clean can regain maybe 30bhp, but curing a vacuum leak can regain more like 60bhp (as well as the 5000rpm kick).

Carbon buildup is an overhyped factor in power loss on this engine - and anyway the carbon will be back to the same level within 5k miles.

This ^^^^

I keep saying it, a remap lasts forever, a cabon clean will need doing again in 6 months.

[Rick_RS4]

i have carbon cleaned mine twice now and checked after 4k miles and it was present, not fully coked up but not like id just done it.

personally id delete the precats then map if your not wanting to go balls deep on modding , stage 2 mani, throttle body port, exhaust, etc etc
