Car ( civic 98 ) doesn't want to rev up 3000rpm, if a hit the pedal like almost 2 seconds the motor just dies. Pull out the map and tps same problem just revved higher to 5000rpm , later on day i will try to get ecu code (oem obd2 ecu)If anyone have an idea for whats is the problem I really appreciate.

 

check your ignition timing

 

Pull the CEL codes. Jot them on a piece of paper.

Reset ECU to clear the codes.

Run engine until CEL remains on.

Pull codes and post them.

 

I doesnt have any obd2 scanner so i just jump with a cable the blue plug and get the code: 7 , 14, 22, 41, 54... my b20 doesnt have crank sensor yet, and also o2 sensor .. idle are connected but doesnt know which color are the cable ... , thanks!

 

What ECU are you using? Reset the ECU and see what codes come back and then post them.

 

Using oem ecu 98 civic (i reset it ) if a plug harness +p06 chipped codes: 14 , 22

 

There are at least 3 OEM 98 ECUs: P2P (D16Y8), P2E (D16Y7) and P2N (D16Y5), none of which will run a B20 properly. You need an OBD2a PHK ECU from a CRV or at least a P75 from an OBD2a Integra. Code 22 is a vtec code so you shouldn't be throwing that on the P06 ECU unless it has something to do with the chip. For the code 14 you'll have to do a 3 to 2 wire IACV fix if you haven't done so.

 

My car is civic EX, Iacv fix, which plug is it? I have an unplugged one which have 3 cables, is nothe speedmeter or tps and map, what i have to do with it?

 

ECU obd1 new chip and dynoed and all problems are gone 127whp 121TQ just header and intake . oem exhaust ....
