I am having problems. with my car ...not me

2jz-gte in a sc400
phoenix tuning did the harness and that works fine. when i cut the pressure sensor and tap in the e manage it says the input voltage is right but it wont output the right voltage. spliced back to stock then it runs better. any ideas?

 

I'm not familiar with e-manage but shouldn't there an option to adjust the output voltage. Basically the stock ecu must be fooled into only thinking that a certain voltage is coming in. So since the e-manage is in between the actual signal and what's going to the ECU it should be able to tell the ECU the "right" voltage.

 

that does make sense. you are not the first person to tell me this. i have looked but i guess i will look again
