we have a 95 civic si......gsr swap......it runs....but hrows some random code.....for one....stock virgin gsr ecu...code 9 and knock sensor.......wont hit vtec.......so we change ecus.......true spoon ecu......code 6.....still no vtec.....no code for it either........

everything is pluged in....

the setup

gsr block
ctr pistons
itr cams
s2 im
stock injectors
intake
header
exhaust

thats all.........


what could be wrong

 

Doesn't the OBDII motors utilize a knock sensor? Do you have it wired up? Cause the wireing harness on teh 95 civic is OBDI....

 

not its obd1......everythings obd1 both of em have knock sensors

 

anyone have an input

 

use the gsr ecu and check your wiring

 

like i said....everythings hooked up wirings hooked up....stock gsr ecu throws a code 9 and knock sensor

 

i recently did the same swap and there is no knock sensor wiring on the obd 1 harness . you have to wire it in . also check to see if you have the plugs swapped between the vtec solenoid and the gray plug that goes in the side of the head same plug but diff color .

 

all the wiring is plug and play, its an obd1 car, with an obd1 motor, and the stock wiring harness. the knock has been wired in. On the stock ecu we get a knock sensor check, as well as a #6, the #6 has been fixed, now we just get a knock code...with the spoon ecu we get a #9 cylinder pos. sensor...there should be no reason for the codes thrown to change between ecu's that is whats messing with me.

Listen up I will only say this one time the 92-95 si or ex DON"T HAVE WIRING IN THEM FOR THE KNOCK SENSOR. they are wired for vtec but the shoc engine did not have a knock sensor. Here is a link for wiring of the ECU

ok so we i found the problem today...short in the knock sensor wire...the spoon ecu didnt throw a check because it was chipped not to. also there was a problem withthe spoon ecu, it throws a cps all the time no matter what its in. thanks for the help everyone...

 

spoon ecu? real or the chip'd pos from ebay?

Leave some periods for everyone else man!

You should change the title of the thread too so it can be easily searched for in the future when someone else has the same problem. Have you tried swapping Knock Sensors?

Good luck to you also.

 

its a legit one

 

different years and trims have little differences in the wiring.

like i said. check your wiring. all you gotta do is use a continuity tester.

the ecu wouldnt throw a code if everything was hooked up like it should be
