Here is the situation that I have.
I am running a crvtec in a 98 integra LS w/ a jdm ITR computer all the wires pinned into the ecu correctly that i know of. When I was tuning this past weekend the shop wanted to try some other ecus to see if i could make any more power w/ differnt ecu set ups.

so we plug in an OBD 2 a gsr ecu.. NO VTEC checked codes vtec system malfunction

plugged in a 00 si Computer w/ skunk 2 obd2b>obd2a harness ....NO Vtec again and same code

then plug in my Obd2a ITR ecu and again i have vtec and no codes what so ever..

so at this point i am a little confused does any 1 have any ideas for this at all


please help

 

any 1 know
