I borrowed a friends G-Force ECU with the fuel, timing enhancement, and raised rev limit and did some dyno testing of it on my T78 car. Attached is the dyno chart:
As I noted on the chart, the test was done with 26psi on 118 octane on a Dynojet 248C with SAE corrected output. I first made a few warmup runs with low boost and the G-Force. Made a few small A/F adjustments to keep it around 12.5:1 @ 26psi. Then on the 5th run, I swapped my stock ECU back in and left all settings exactly the same.
EGTs on the G-Force ECU runs were at 800C. Stock ECU peak EGT was at 750C. This is especially interesting when the chart shows the stock ECU actaully running slightly leaner. So the 50+ degrees EGT difference must be due to timing retard from the G-Force.
Also something to keep in mind: The car was getting quite a bit hotter by the 5th run. Someone was measuring the IC heat and noticed ~80F difference from the first pull to the last on the inlet side... and with this, the stock ECU still performed better. Max torque with run 003 with G-Force was 548 and run 005 with Stock ECU was 615.
I hope you all find this information useful.
