ok i have a 95 h/b si with a ls and b16 tranny however the car only goes up to a crapy 6k rev what is causing this i know it has to go to 7k with the ls ecu i have in there

 

does any have a freaken clue

 

Does it throw a code? Did you mod the engine at all? What is the code on the ECU housing? Are you sure the TPS is positioned correctly?

 

can it be the timing or sensors? i mean im realy stuck!! on this one

 

what do you mean on code on the ecu housing i know its a p75 sometimes the check engine light turns on and some time it doesnt i dont know what the hell to do

 

if your engine is running too rich, it may be that your o2 sensor is wired wrong or needs to be replaced... if it runs somewhat normally with full power, then you may have the wrong ecu... recheck your wiring... 90% of swap problems are wiring related...

 

Check engine light?

 

2 things:

1) How do you KNOW it's a p75? That's why I asked. The center set of numbers on the bar code on the ECU will tell you what the ECU is. If it says P75 then you have a P75. Might as well check to be 100% sure since it's easy to do.

2) Have you checked the code for the CEL? It doesn't just come on for no reason. Jump the ECU and test it. If you don't know how, look in the Civic section in the Online Resources thread for instructions. Report what the code is and that will help us help you.

 

thanks for the info and yea im sure its a p75 i have two of them they both do the same crap im gunna see what code its is throwin out

 

the check engine light code is the map sensor and speed sensor could this be the problem i have of only a 6k rev
