We just had a first gen b16 put into a 95 civic dx coupe. The motor has been completely rebuilt with new ctr oversize pistons/ crane stage 1 cams/ crane titanium valve springs and retainers/ all new gaskets- bearings etc.../ and we used the obd1 sohc vtec ecu (p28 i think) that has been remapped. The motor now starts and idles ok but will not rev above 3,200 rpms. It seems like it starts to choke at that point. 3 error codes show up -- 1 for a fuel injector and 2 for the vtec solenoid. Those don't seem like problems that would limit the motor from revving. When starting fluid is sprayed into the intake man the car will rev much higher --- Anyone got any ideas? or seen this before???? PLEASE HELP -- we've spent so much on this engine already. oh -- its running on a gsr distributor and injectors.

HELP HELP HELP HELP!!!!
thanks guys

 

check the tps, you said it has three codes, what is the other code.

 

try using the b16 ECU, I tried using my stock civic ECU on my LS and it ideled high and ran like shit. I would get the right ECU

 

two codes for vtec and 1 for injector, can't use the b16ecu - it's obd0 and the motor has been converted to obd1 to match the car.

 

get the proper ecu or get the p28 chipped....it will run like piss with that ecu in there.

 

he says it has been remapped... anyhow i am guessing that it is the ecu also, what about a p30 ecu since everything is OBD1 now, the p30 will come out of a delsol.

 

2 cents:

AEM Engine Management. Get it tuned. Your aplication is exactly what its for.

 

my buddy had same problem with his b16b it was his tps sensor
