First off, whats a good TPS voltage to enable AFR tracking, same goes for RPM.. Gain, is a higher or lower value better..
Second, what exactly is MAG g/sec and what kind of adjustments can I make with this..
Think I might be bumpin up to 550 injectors soon.. have been able to boost to about 18psi (around 20psi spike) and everything holds pretty well with all of the adjustments you guys suggested earlier, but seems to go kind of flat as far as accelerating in the higher rpm ranges, I richened my HI-load high rpm range, and that has helped a bit, but would like to go beyond 18psi without sputtering or loss of acceleration up there.
Thanks for all the help!.. Good luck to all (including me) with the tuning! |
Ive got my AF tracking throttle voltage at 1.9x....gain I think you want the lowest value to accomplish good response. Mine is at 12%. MAS grams/sec is just a airflow measurement....you can watch this value on the sensor mode I believe...just another way to adjust on volume vs. (instead of just) rpm....I don't currently do any adjustment with g/sec....but Im sure it would make more sense than rpm for some situations....one thing ive noticed with AF tracking: it seems like I need to bring the "lean max %" up to 12% or more to accomplish 11.5 afr....but I think it's because of these piggish 560 EVO injectors....so far I average 11.2 AFR or so, so I think I need to raise it even more....but my point is, I do notice it working as I raise it...just have to raise it more than I anticipated I would.....what turbos you using? If 9b's, that would explain the "flatness" on top, Im sure....generally I need to lean out in the upper end, rather than richen....I also have timing control though....
