Hi, I'm (starting) to use TunerPro so I can hopefully get my very rebuilt '87 454 TBI motor to run.

(For those interested: Edelbrock Mutlipoint injector intake, ally heads, roller rockers, 202/210@50 cam, 9.5:1 compression)

I'm taking my current prom (from the Edelbrock multi-point intake conversion) as the starting point. It ran with 8x19lb/hr injectors, which I'm changing for 29lb/hr ones, to support the expected 450hp.

So as a simple starting point, I'd like to alter the fuel tables to at least be aware of the bigger injectors, in the low rpms and idle, so it doesn't overfuel.

The thing is, I can't see an injector constant anywhere in the TunerPro lists, am I missing it? I imported 7747-mine.ecu defintion downloaded from the TunerPro site and saved it as 42.xdf. Am I missing the constant, or should I just alter the VE / fuel tables directly if there is no alterable constant?

Many thanks.
