These are in Tunercat.

1. Max rpm or extended rpm spark. mine set 4200 rpms?

2. Minimum speed to enable highway mode spark. mine set 75 mph?

3.speed to enable OL idle. mine set to 3 mph? does that mean OL operation below 3 mph? like at idle? i assumed i idle CL.

4. IL idle AFR enable rpm threshold. mine set to 600 rpm?

5. as above cept disable. mine set 650 rpm?. if i idle at 750 does that mean OL disabled?

6. DFCO enable speed. i set this to 65 mph. i did so anticipating this function will only work until i reach 65 on slow down meaning i am at 75 and let off gas i will see CL and 14.5/1 at 64. did so to keep manifold somewhat saturated with fuel. saw spike on WB off chart lean on prolonged deaccell..



7. above disable is set to 55 mph?

8. enable rpm is 2200 and disable is 1800. so i assume no dfco below 1800 rpm??

9. enable map- 22 kpa and disable 35. seem ok?

10. dfco max tps is set to 1.2%. does that mean only functioning when i let off gas completely? i did have occasional dying when exiting xway from 72 mph to zero when i shift into neutral(manual). my WB shows superlean when it dies. 17.5/1 FP(80 lbs inj's). i think pulse width is too small. loaded tunerpro4.0 rt so will check that. car in shop past 2 weeks for paint.

thanks in advance for the info.

each of you take two Q ?

 

1. Assuming your spark tables are the same as the 8746's which I think they are. This is the spark advance that is sloped in after the tables end at 3600 RPM. Your setting means that the value for slope spark advance will be added to the last value in your table up until 4200 RPM, at that point it will remain constant.

2. You have highway mode spark advance terms and fueling terms. In highway mode you can lean it out and add spark advance for fuel economy. There are probably only a couple degrees of extra advance from the factory. This advance will be added at 75+ mph.

 

thank you! next in line step up to plate.
