I copied everything over from my MAFS 94170715 map that runs great and used a Spoolin' Up SD harness to plug the OEM MAFS plug into the AIT sensor in the UICP and the GM-style 4-bar MAP sensor I've been using. Installed a Tial BOV and filter straight to the turbo.

The engine will start up, revs jump up as usual and then drops right back to 0 so it doesn't even hold an idle. This is the "Phenom SD Fix" ROM so is there anything I might be missing?

 

Bump. Does the OEM plug for the MAP sensor stay unplugged while the Spoolin' Harness takes over? Not sure what I'm missing here.

 

Ttt

 

I'd swap over to the 9653 since IIRC it's more defined.

Post up some logs of everything plus IACV Position in steps or % and IACV trim.

 

I downloaded the 9653 SD ROM a few days ago and started copying everything over, won't get to try until next week as I'm out of town. Just wondering what simple thing I could be over looking as it's my first try at SD. If I can get the car to start and idle then I should have not problems from there.

 

How do you have your connection for the Map sensor? Are you logging in Evoscan, check to see that Map sensor is reading correctly first off and that it is scaled properly in your rom
