i have a 95 civic with a b18b1 swap. my car runs good but it revs out at 4200 rpms in every gear can someone please help it also has a chipped p06 ecu but the chip wont allow the car to start and a p75 wont let the car run only the p06 works also i think the ecu is tuned with hondota n for a turbo i get bad gas mileage to i thought hondas were supposed to be good on gas i get 180 at the most to the tank it also had a turbo but they took all that stuff off wen they sold it to me n now im stuck with a car with bad gas mileage n it revs out a 4200 if any one has a clue please let me know

so it wont run at all with the stock ecu?

nope i have a stock p75 n it will almost start but wont and then you start smelling gas it will only run with p06

Did thay take the bigger turbo fuel injectors out it could just be the motor flooding its self

and the remap on the ecu for the turbo is probily set to give a big boost at the 4200 rpm when the turbo spools up so agein its probily flooding its self out

Id say go to the junkyard get some stock injector and check your vacum lines and map sensor

ok ill try that

yeah the fuel maps and everything are completely wrong because its tuned for turbo... start with the stock injectors and stock ecu and go from there.

thanks im try that i have to use stock ecu for car which is p06 but it says p75 for the b18b1 n i have one but dont work n its stock so im guessing stock ecu has to be for car itself if the wiring harness hasent been changed

the p75 is the correct one for that B1. So if the car wont run with stock injectors and stock ecu, either the ecu is junk or you have another problem.

is the car a auto or 5speed cuz maybe thay put a auto ecu in a 5speed or viceversa

the ecu is manual

you should grill the guy who did this swap.. ask him how he did it and why the motor wont run with a stock ecu..

the guy got me good i guess

is the guy not responding to ya? is he someone that you know?

As long as you did not pay a hole lot for the car you got a pritty good setup

It looks like its just a matter of fixing some one elses f@#k ups

From what Iv gatherd so far the guy that put it all togather did not know what he was doing thats why forums like this are here for to help


How about this have you ever seen the car running around town with the turbo and all that cuz im starting to think the guy put it together and couldent get it to work and sold it to you

i only paid 1300 n no i havent seen the car around town he lived a good ways from me i think he just got me n im have to fix all his mistakes

Sounds about right look even if you got to spend alittle money to fix his mistakes you still got one hell of a deal so dont get dishearted

yea im fix it up im bout to replace the tie rods n cv shafts but i got all the inner n outer and i was wondering should i replace the cv shafts in pairs like the tie rods

Most people just replace the cv shafts as thay go bad if ones ok and ones bad just replace the bad one it dont mater with them just rember the short shaft is going to be the one the power gose to so it should be the most warout

yea the short one is the one thats bad thats the passenger side

turns out my rack is bad not my cv shaft and my wiring harness is a chopped up just make the car run harness
