They work, kinda, as in they should start and run the car... no promises from there. In other words, you do need to match trans type.

 

Ok I got Code 55 and code 4 Code 4 is CKP and I dont know what the hell is 55 Anyone know if that is even a code???

 

on which ecu is the codes coming up... if you want send me a pm and i will send you a list off all the possible codes and how to read em... good luck!!!

 

ok...i checked for code 55 and didn't see anything but i might know whats wrong code 4 .. CKP Sensor (Crankshaft Position Sensor) defective circuit or unplugged / defective sensor... did you do ALL of the wiring need to convert from a dpfi to mpfi... i am pretty sure that, that sensor is located in the dizzy and is need for the engine to start...i had someone run the wrong wire there once and it wouldn'
t start... it took me long as hell to figure it out...

 

I change the IACV sensor and i pugged in the LS ECU and it seems to idle fine but when i went to drive I step on the gas and it shut off what could it be now? just got the ECU from a local junkyard maybe they gave me and automatic one instead of a manual one How do tell if auto or maual its a P75a03 Ithink i have to double check that

 

I personally don't buy ECUs from a junkyard unless I am the one who pulls it out, or I watch it get pulled out to avoid problems just like this. I don't even remember how to tell the difference without trying them... go to an Acura dealer and ask them to look up the part number. That will give you the answer fast.

 

i agree with kai... go to acura.com and find a dealer near you and ask them to check the ecu... also since you went from dpfi to mpfi did you remember to switch the wires at the tps???? just a question to check...good luck!!!

 

Don't forget, this guy posted in the wrong section, he has a 6th gen Civic. The mods haven't been around to move it yet...

 

Do I have to re-wire the TPS in the 98 civic?

 

i am not sure about the 98 civic... but i know for the 4th gen civics you have to switch 2 wires around... but i dont think any of the newer civics came DPFI.. so i dont think it would matter... you might wanna try posting on the 92+ civic board they might be able to help you out more... yea kai i forgot he didnt have a 4th gen civic... i dont think you mess with the tps... o well good luck
