I just spent the better part of two hours bombing around in the Z to get some data in order to attempt my hand at tuning the PumpEff table. I hooked my WG can direct to manifold vac, then dragged took the engine up to 2000-5000 RPM in increments of 500rpm, dragging the brakes to hold it for a few seconds until my AFR stabilized. I probably should have taken it to 6000 or 6500, but I didnt want to attract more attention to myself on the back road I was on that I all ready did.

Electronics are an 87 LM running Rob's Turbonator v13 code. Engine is a 2.2L with forged pistons in a .020" oversize. Ported 782 head with +1mm valves that flows 171 @ .500 on the intake and 141 @.500 on the exhaust, TU R5 camshaft, ported 1pc intake, 52mm TB, ported stock exhaust, and a S70 w/ .48 exhaust housing and 3" swingvalve, full 3" exhaust, 52lb injectors run at 55psi static, although to make the idle not crazy rich without knocking the PumpEff down to like 74% below 1500RPM I had to scale the injectors for 57.5lb. Is that the right approach or should I scale the injectors back to 52lb and adjust the PumpEff or FuelBaseFromMap to taste?

When I started my AFR went from 11.5 around 2000 RPM up to almost 13.5 at 5000 RPM. Now it's a much more steady 11 to 11.8 or through the same range. I need to find someplace to take it up to the rev limiter and see how it does up there. But, just for my own sanity...this doesn't look stupid right?
