I am using 1227165 ecm with $6e mask (factory) with a modified chip for an 89 firebird 305 TPI.
I have found the parameters in TunerproRT for disable and enable fuel, for both mph and rpm.
I am wondering if anyone has used them (say for a kid's car to limit speed, or just as a plain rev limiter for engine protection).
what has been your experience, and are there any suggestions ?
