B18c in limp mode

[Tate2k]

just put a b18c in my 99 hatch it a 95 gsr obd 1 i havent set uo vtec wires but should still run when i rev in N it wont rev pass 3k im lost at this point.

Taking a shot in the dark but try diff ecu?

[mittimmytimmy]

What ecu? Did you wire knock sensor in?

[93supercoupe]

its the dizzy. Or the wiring.

[Tate2k]

running a p72 with chip and wired knock sensor im gonna try the dizzy is the ls and gsr dizzy the same

[SeanJDMJohn]

Tps nd map backwards? U might have the plugs backwards happened to a buddy of mine

This^^... Any codes?

[Can~i~bus]

Bad tps or suttin easy

[SeanJDMJohn]

Like I said I had the same problem on my buddy it wouldn't rev past 3k nd on mine it wad idling at 3 nd wouldn't rev past I switched the map nd tps plug shit runs mint happens all the time

[Tate2k]

codes p0113 and p1298 i will rev the Tps nd map

I would hope that if you swapped this motor you would be able to tell from the length of the wires alone which plug is for the tps and which is for the map - but non of these are your problem nor is it your dizzy. You said the motor was a 95 and u put it in a 99. You either didnt hook up the crank sensor at all or you dont have the proper crank trigger meaning the spoket the timing belt rides on. You know the one with the little dog ears sticking out. Change that from the 95 (No ears) to the 99 (with ears) version and you will rev to 9 in no time.

fixed now but it was the dizzy

[93supercoupe]

Intake air temp and eld. Neither one of those codes will put it limp mode. But if its limp mode Nd not showing good codes, im willing to bet its the ecu.

Open the ecu up, and look for a little jumper wire. It will labeled j1. Clip the jumper so its not making any contact. That will bring the ecu back to stock


But it sounds like its hardware failure in the ecu. When you have it out, smell the circuit board to see if something is burnt. It shouldnt smell like snything

9/10 its a wiring issue. And about half the time it's something with the dizzy

Maybe a clogged cat it happened to me besides wat everyone else said to
