Ok I'm having an issue on the gm 3 bar map,it's brand new.I follow the direction on HT here on how to connect the wires everythings went smooth untill I start the engine,it wont idle at all.As soon as I start it up the rpm would go about 3 rpm and then just dies.so I hook up the wires back on the stock one and starts up fine.I thinking it's defected.what do you guys think?Any input would be great.Here's my setup incase you guys are wondering.It's a full gsr built with stock sleeves gt28rs getting ready to take it to bubba but this happens.

 

double check your wiring for your GM MAP. May have accidentally crossed the wires.

 

u realize you have to change the map sensor configuration in your software to read the new sensor's values as well as the physical sensor on the car.. right?

 

^^ same with him.

 

i'd recheck your wires and what ems are you running? Like Running925 said you have to change the configuration in the ems so it will read the 3 bar..... I went off hondata website and mine started up just fine.

Thanks guy.I didn't know that the stock ecu wouldn't be able to reconized the map.I will be using the hondata s200 when tuning.Again thanks
