Alright guys. Im having some issues well above my expertise. I recently finished installing a ms2 chip and changing from the the CAS to Full Function Engineering 36-1 trigger wheel. Im currently running the 3.1 firmware. The problem is under boost the car feel likes a misfire but its not misfiring. I have installed a new coil, plugs and wires. I datalogged the issues (which I have attached ads well as an msq). Anywhere between 50%-100% throttle high rpms the car will start bucking, under boost it feels like a rev limiter. I noticed that the injector PW drops down and up with no loss in sync, I would think its making the car feel the way it does.

I have done everything I know to do. I have the grounding correct, two shielded wires from the vr sensor. Im out of idea. Thank everyone in advance for looking and helping

Thank You,
Jose Nieves

 

My datalog was too big. Ken Ill just email it to you

 

I think you probably need to check your MAPdot accel threshold. You probably need to raise it.

I run it on tpsdot acccel mode.

 

It feels like its misfiring when it happens. Im talking stomping on the pedal at low rpms and when it reaches the higher rpms its starts breaking apart and the injector PW go up and down as the car is breaking up

 

If you're not using MAPdot, make sure you doublecheck the thresholds anyway. Also make sure you set the decel settings to 100%.

 

Ken thank you very much. Tps dot threshold fixed the car. What is a good settiing for it or an easier way to dialed it in?

 

You should most likely look at TPSdot while you're having a problem, and then increase the threshold to a bit above that.
