E30 Stage 2 MHD stutter 340i
Hey guys, been running this for about 3 weeks.
I have my transmission XHP flashed to stage 1 also Anytime when I suddenly put my foot on the gas the car hesitates or stutters. I have to almost all the time be so careful of how I put my foot on the gas to ensure a smooth acceleration I HAVE regapped my spark plugs to .022 with NGKs but the problem still occurs Any advice or thoughts? Thanks guys |

When you go into the MHD Flasher, in the bottom right corner there is a tab that says "codes". With your ignition on, engine off, run this and it will give you a list of DTC's. This may lead you in the right direction if any of your onboard sensors have registered an error. Go ahead and post your codes up once you pull them and ill see if I can be of any help.

Is it possible you're experiencing traction loss and the car is intervening? The only reason I ask is that you said it only happens when you get the gas "suddenly".
I've had similar experiences and turned out it was traction intervention. Try turning DSC completely off and see if you can recreate the hesitation.

same happens to me, from a green light, foot down, wheels spin, but you're moving. get to another set of lights, once they go green, same amount of pressure on the gas, but you're moving like a snail.. and then BOOM all the power of 100x F1 cars all at once. |

have you logged this phenomenon? You've posted before about running e30 fuel mixture on a 93 octane map. Are you still doing this?

How are you measuring your E30 mix?
