Renntech ECU tune for the 1///M
Didn't see anyone mentioning this before (sorry if repost). Renntech now offers a tune for the 1///M. Dynoed at their place (stock just so I get a baseline), great guys, met the owner (and one of the resident ECU tuners), top notch place.
Not sure if anyone is running it and can comment on it. http://www.renntechmercedes.com/www/node/630

Love your avatar, impressive times with the tune! Am curious myself what I'll put down, seems only difference IIRC is you have FMIC and a DCT car (Dinan end cans, right)? Would be stoked if I can get a 12 sec flat. Hartmut himself may actually do a couple of pulls for me, Lenny thinks we may even crack the 11s if the conditions are right and launch is proper. I'm not sure there is a 1M with solely a tune that has cracked the 12sec mark. Will let you know next time I hit the drags and we should def meet up regardless! Needless to say, car is a beast. To me, one of best, if not the best, tune out there. One of several reasons I returned COBB with no hesitation... Quote:
I promise I will post my results soon, I know I have been saying that for a while, but will get to it, including the Cobb vs. Renntech graph, done same day, on same car, on same dyno, on same gas tank, same strapping method, same operator, same tires, etc... Can't get any more apples to apples, and the results speak for themselves.

I am googling away trying to find more enquiry posts on RENNtech and BWM and here I find you....amazing ! That 12.00 ET flat I did was on mere Dinan FMIC and Dinan free flow exhaust and had same day installed the aFe Stage 2 sealed intake and was doing back to back 12.0 ET runs. It was roughly 74° that day, if any colder I would for sure break 11s On the May 6th PBIR private event I was consistent 12.2 in 90° temps traping 114...hahah....I thought the car was going to bog down but it ran 35 runs with no trouble codes all day long. DPs are going on the next week and I will be FBO. This Friday I am heading to Japtrix for another dyno run for the upgraded aFe Stage 2 "elite" intake. When DPs are installed I will be out again to PBIR to test run after adaptations. Hoefully by then we can hook up. |

There is no question that the Renntech tune will show far greater gains than the off the shelf Stage 1 map as Renntech is a custom tune tailored to your car though. If you had the supporting mods, I don't think you'll find much difference between that and the Stage 2+ map though... Were these runs achieved on stock runflat tires? |

In fact I wasn't really considering the Renntech offering until I went to their (very impressive!) facility to get a baseline dyno for the car, and the Cobb tune delta. I was already unhappy with the Cobb tune and the dyno results proved my comments and reservations both graphically and numerically. Renntech at the time had an early Beta themselves, and offered me the Pepsi challenge, so I took it. Even that early Beta was better in just about every way to the tune I had, and their subsequent version (and final Stage I) nailed the several small comments I raised. And BTW, I was running a custom map Cobb had sent me after many hours of data logging, which I in turn sent them prior. But indeed, Renntech spent the extra time developing their own Beta, when the other tuner at the time did not, and hence the results were not even close. I should note this was an early stage Cobb Beta, and for a long while they didn't have a shop car so virtually what they had rolled around Chritsmas time saw no development for months. It soulds like lately they have devoted R&D time and improved it, which is great to hear, and frankly something you would expect from a company of their stature. Once I slap a FMIC, and perhaps catted DPs I'll go for Stage II.
