HEy,


I have a a PND Kproed ECU on a K20a3 base RSX engine....under any conditions Vtec is not engaging....the Vtec solenoid is A-ok double checked it... the ecu is not sending any signal at B15(VTS).... when we manually give the power to the solenoid it activates Vtec... wat could be the problem here... anyone??

Serial Number: didnt notice
Calib: Stock K20a3 base 91 octane
datalog: hangs as per the vista problem
vehicle: civic 2003
ECU: PND
modification: base k20a3 into a 2003 civic
Problem: Vtec not engaging. every wire is in its correct location in the ecu. Vtec solenoid is working. K-pro is not turning the Vtec on nor switching the maps. It was giving out the Cam phase error but i have disabled it. No error code in the current situation.

Interesting part: I installed a vafc and voila Vtecs workin....but still ECU din pick up the return signal or watever to switch the maps....reorganized the maps according to RPM n cars goin pretty much better with the Vtec.

Any solution??

wat no answer....:D

would non resistor plugs cause VTEC not to open...:D... i think no...:)

Fix the cam phase error first.
