Hey Hey,
I'm about to build a custom exhaust manifold and exhaust for my car and to run it I bought a socketed P28, basemap chip and conversion harness from a Honda-tech vendor.
The car was on a rolling road yesterday with the stock ecu and made good power there are no problems at all.
This morning I tried the chipped Ecu and straight away the CEL light came on. I drove the car a couple of miles until it has warmed up and everything seemed fine in fact it idled better than the stock ecu. Once it had warmed up I found that V-tec will not engage.
I came home and chaged back to the stock ecu and everything was fine, No CEL and V-tec engages fine.
I am going to email the vendor but does anyone have any ideas.
I am going to continuity test the adaptor harness and then check the fault code.
Couls someone tell me where the diagnostic plug is located please. 97 EK4.
Thanks for any help
