I am running a Techedge WB v1.5 with a P28 ecu (w/conversion adapter on board so no wire harness here). Trying to do some datalogging with their TEWBLOG v2 software. At the moment I have rpm input and AFR readouts but trying to also hook up the MAP input to it so I can read boost. The question is simply, do I use the std map output pin on the P28 or direct from the GM 3bar map sensor?

 

i just spliced into the existing map singnal wire at the ecu....thats if you wired your 3bar up to the exist plug for the map sensor in the engine bay...which now thinkin about it would run if you didnt

 

I will give it a try when I get home tonite
