okay im a idiot my ecu is #78.c i did a search. okay check engine light is solid red. did the standard dial procedure w/ecu. the green light and red light stay on. does it mean there is no codes to read or is there something else wrong. its got to be if the check engine light is on.

also im not getting a throttle signal, from what safc is saying.im running z32 maf. safc is set for 2in 5 out, selected hot wire in sensor type menu. the car starts up then bogs down then cuts off. if you run a fan over the filter the engine pics back up.

i did unhook battery to reset and it still does it.

these are my problems that are holding me back from completion now.

#28? That's odd. Take a pic of the inside of it. I am curious.

it seems like my ecu is in limp mode. after searching i found that my safc is not set right. im running 2in 5out. its supposed to be 2in 7out with z32. ill see if this will make the engine run better. would the safc cause the ecu not to run right?

of course, if there is a problem with the maf reading it will go into limp.

your right, the more i read into this off boostcruising sticky, the maf seems like the culprit, goin to backtrack maf wiring and make sure that is good. check grounds off ecu. since the car has been painted some grounds might not be grounding.

Make sure one ground goes to the ecu and the other to the chassis.
