what do you think of above? next spring i willbe completing the drivability tuning of my new set up and will begin performance tuning. i will do a dyno run with chip A and Chip B but that is it at dyno. That may be with two diif PE a/f settings. maybe commanded 12.5/1 and 12.8/1. i have a dyno run on prior set up as a base. spark curves will come later and only way i can see results will be the cruise at 70 mph on level road with the lower MAP the winner. no level roads here. but that is only for that MPH and only that RPM. seems one could do that all over the spark table until you go bezerk(sp?). maybe you could offer the rpm/map where i should concentrate. this is all closed loop spark. now on the 1/4 blast would the GTech be as valuable a tool as the WB02 has proven to be. comments please.

 

You can completely miss the tune using either. Using both gives you a high probability of hitting the right tune.

If I had to only use one, it'd be the WB.

 

Grump: how would that help with the SA? that is WB only. sitting on dyno too costly. seems i have a "stock" GM .bin with values as such. i hit KC around 2400-2800 at 50-60 MAP day one of logging. pulled a couple deg where the KC occurred and it went away. with 93 octane. switched to 89(93 went to like 2.60/gal) and KC did NOT reappear. aware KC NOT a tuning tool.
