I had this management on my old fezzy. Please get it mapped properly. The problem is when its on song its fine but on idle it will run rich as hell. This is because you want fueling for a 1.6 but the ecu thinks its fueling a 2.0.

Get it mapped properly. I did'nt and tried many times to get it sorted but in the end had to have new rings, shells and everything due to bore wash. Than had to get it mapped.

But once mapped it was a real beast.

This car will be back soon as the guy who owns the engine will be putting it in his car soon.

Good luck anyway.
