Stienbauer and AC shnitzer
Well I'm looking to get some views on the 2 tuning options from Stienbauer and AC.
Both use, from what I can tell, pulse duration modifiers piggybacking the stock ECU, they are claiming 60bhp increase with no DP or intercooler. AC is expensive at around £2500 but has a warranty of 2 years Stienbauer is cheaper at around £1200 and only warranty the unit I used the Stienbauer in the past on a mini jcw and it was fantastic, dynoed at 250whp - with excellent afr- and was switchable on/off, and With it off it showed 218bhp on the Dyno, so it works Just wonder about the m2 and the ability to take a n extra 60bhp I also like the fact you could remove and dealer wouldn't be able to tell it was installed. Any thoughts welcome |

it would raise a lot of questions as well. Terry says 20whp more on 93. That's where the 30bhp comes from. 60bhp would be great, but how?

So the guys at stienbauer are going to send me the box and if it's not producing the quoted power on my stock m2 will give me my cash back.
I should have it by next week so fingers crossed. |

OK... I've bought the stienbauer unit so Il install it this weekend and get it on the dyno next week to see what the results are. I'm hoping 30-40bhp

Installed the stienbauer unit today and wow!! What a difference, especially up at 4000rpm and above. I done some pulls but the road condition were a bit greasy. A/F looked fine, timing was OK and iat was about 10c higher. Overall, it's impressive. I've got dyno booked 2 weeks today so we will see what hp gains we get. On the road though, it felt really strong, I'm guessing 30/40hp

Well it's disappointing.. A 10bhp increase with the piggyback. Stock runs were 388hp but the delta was 10bhp between stock and tuning box, that's the important bit. I guess we just verified that the piggyback tuning is not the way to go with this car/engine.
Also, iat were up at a max 80deg Celsius on a full power run, we let it cool to 28 degrees C in between runs. The timing was being pulled above 5000rpm both stock and piggy due to high iat Temps. Afr was at its lowest 10.9. I was using shell v power 99ron. I wouldn't say the intercooler is poor, when I'm going hard on the open road I never see temperatures like that. So the story goes, if your tuning an m2, get a flash. Unless of course, you can get a piggy custom set up on your car, might make a difference. I'm also sure the ac shnitzer system is made by steinbauer. |
