I am tuning an LS3 crate engine with a Speartech harness and E67 ECU.
I got the pedal and everything from Speartech. The engine is in a 71 Chevelle
SS clone.
I am doing VE tuning with EQ VE and am now working on the high RPM tuning.
I am logging TPS and ETC pedal position and see that my TPS never goes higher
than 83% and the pedal position maxes out at 86%. I am sure the pedal is stroking through its full range. Any ideas why the pedal and throttle position never reaches 100%?
