Accel DFI gen 7 tuning....

Injector offset is nothing more than a compensation for the mechanical delay in injector opening time. As an example, if you had a commanded pulse width of 2.2 ms and the injector took 1 ms to get off its seat, you would have a net opening time of 1.2 ms. The required offset varies by injector brand and size. 0.80 is a good default starting point.

By adding to that value you effectively richened up the entire curve.

Thanks for totally clearing that up. Richening it up across the whole curve is exactly what Don told me it would do.

I tried last night to bring it down and it really slowed the revs time to go up down and it just seems to like it around 1.5.

What will I have to do to the other tables to bring it down? I have tried some changes to see how the engine reacts but each time it never seems to be enough by doing one table. What would be the amounts across the spectrum to bring the time down to .080 and still be rich enough?
