ECMlink possible ecm issue?

[my97gsx]

I had my car tuned. keep getting knock retard readings and over all could only get 320ish wheel horsepower out of my e316 setup on 93 octane fuel and about 23 pounds of boost. when I lay into it when its colder knock retard occurs. also I keep getting an injector 2 circuit malfunction. it happened once on the low impedance injectors. then those were replaced with 1000s high impedance and the resistor eliminated. checked wiring and it looks good. wondering if maybe my ecm is the cause of these faults.

Is it dyno tuned? How are you tuning the car if the wideband and MAP sensor aren't logged?

What he said. Can't see afr's but if your ve table is set, then the Global is off. You want 100% ve at 5000 & 5500 rpms at WOT.
