Well where to start. I have a 95 GSR with a B18C1 head and a C5 bottom end. The head is fully built with cams, valve train and port and polish job. The bottom end is completely stock. I have a P28 ECU OBD1 with Hondata S100. My problem is that my car will throw a CEL every once in a while and it won’t give me a code when I jump the two wires. When the cel is on my car won’t go pass 4000 rpm and when I gets to there it sounds like I hit rev limiter and up till 4 grand it runs fine like nothing is the matter and that goes for when it’s not on as well. Do you guys have any ideas or solutions? I’m thinking it’s a tuning issue but not sure. Any help would be greatly appreciated.

 

are you sure your jumping your ecu correctly? sounds like my buddies car his CEL would only come on once in awhile but when i jumped his ecu i got a code 58 which was tdc sensor #2

No im doing it right. Cause before it came on for a different reason and i got a code but now i get nothing...

 

then check your wires.play with your sensors and see if it throws a CEL
