i got a 92 civic w/ ls-vtec. with chipped p28 running uberdata
it had been running fine no cels, till i put on the vtec head (I am using a stock ls map with vtec enabled for testing) now my car revs up and down (x14)
then goes in to limp mode, and if i try to check the code i get a soild light ( no blinky blinky) could my problem be my base map? i thought about runnin a gsr base map till i get my hondata. do u think that would be ok? (if that is my problem)

 

limp mode is rev limiter at 3-4k

u probably have a bad basemap
try a differet program or
cut j1 on the ecu
it will return ur ecu to stock

 

i've got a 93 honda civic dx with a ex harness. a b17 with a chipped ecu out of a 93 gsr it done the same thing I had a connector to check the code the negative side had come loose in the harness. as far as the limp mode mine cuts in and out really bad fells like the rev limitor im still working on my problems it has something to do with the distributor. im going to replace the cap and button try to clean the contacts
