Twin screw and TMAP ~ HELP
 

To the Whipple/Kenne Bell folks...I have the IAT connected to the TMAP. Do I need to connect the MAP wires on the TMAP to the computer/harness and if so can you tell me what pin/s or wires in the harness? This is on a Whippled Mach. I already have a base tune loaded from LaSota Racing, car is running but has not been driven yet and needs to go to the dyno but I don't want to get there and someone tell me "oh, you need to wire in the MAP circuit!"

It would seem to me that without wiring in the MAP the computer won't know I have a blower. Am I wrong in my thinking"

Thanks for any input guys. This mod has taken forever..........but that's been my fault. I'm SLOOOOOOOOOOWWWWW!!!!!!!!!!!!

Im running 03 Cobra wiring + 03 Cobra ECU so no direct experience regarding the mach ECU/Wiring harness...

However, I can say the mach ECU will be more concerned with pressure drop across injector measurement from the FRPS in terms of determining fueling needs. It really doesnt need to know manifold absolute pressure, it just needs to know if desired pressure drop is 39psi and current fuel pump duty cycle isn't acheiving that, it will up the fuel pump duty cycle to compensate.

Thanks...........you would have thought I would have investigated this earlier than now. Hopefully someone will chime in. I'm wanting to take it to the dyno soon and having someone else wire it up is just another delay. I'm running the Mach FRPS but have the GT superpumps and modified FPDM from Lethal with 60 pound injectors.
