well, i wire everything up, and nothing. everything exactly per the manual. i dont know why, but it just wont power up. then when i go inside and turn it on via an old pc power supply, it works like a charm. i dont know what could be the problem one damn bit.

i was thinking maybee pull the 12v from somewhere else and not the ecu, and then put the grounds where the ecu should go. i dont know, dont ask me. i thaught it was broken untill today. i was also thinking... well, it runs fine on the pc powersupply, i can just ground the two wires to the chasis. i dont think it really needs to read the voltage too much. only from the tps, rpm sensor, and the airflow corrections thingi mabober wires.

yeah. so can it be done and what effects will there be if i do it like that? because i wired it up EXACTLY they way its supposed to be, and it just will not power up. so... ????

 

ok this was relocated.
