So I'm heading to the dyno next week with my newly VVT'd NA and would like some feedback on my starting points, and my planned strategy. My setup is a 52k mile 02 engine in my 95, with an MS3 Basic (Rev built), square top manifold, RB header, borla catback, no cat, and the 3d printed ABS cold air intake from alec moody.
First, my starting points. I haven't touched the VVT or injector timing values from Reverent's baseline tune. Found the AFR target table on here and have autotuned VE on the street - the car seems to run really well. I have also enabled time-based and enhanced acceleration enrichment. I've messed with the time-based on the street but left the eae at the default values - the car feels good at steady state and under transient throttle, but I also have ego enabled
I'll be using a load-bearing Mustang dyno, with det cans, and I have up to 4 hours if I need it. After reading all over mt.net, I think my strategy will be this: First, run through all the cells with VEAL to make sure that is spot on. Then, lock RPM and run through load cells, adjusting timing in degree increments as I go (adj fuel as needed). Do this for RPM columns from 2000rpm to 6000rpm (every other column, ~every other load cell?). Interpolate between columns and load cells. 60 second break between columns. Adjust the upper cells through WOT runs, with 60 second breaks in between.
Next would be accel enrichment. I've read all through the EAE thread here as well as the AE resources from msextra - just use the AE wizard to put inputs in at varying TPSdot, adjust curve to get best feel w/ reasonable AFR. Slow increasing throttle input on EAE atw, decreasing on sfw until I get stable AFR's going both ways.
If I'm not exhausted by then, I'd like to continue on to the VVT tuning. Step one would be to see how well actual cam angle matches what's in the table. For this, how close is close enough? Here is a log from the street:
I'm open to suggestions here - not sure what direction I should go or how to tune it.
And finally... injector timing. Reading through the other thread here, it looks like I should tune it similarly to ignition timing, except my goal is to maximize AFR. Once I've got that for every cell, run VEAL a last time and go home.
Is this too much? Sound good? Bad?
Edit: Should AE come before ignition tuning?
