2. What RPM should I go to when doing the auto ve SD tune? 4,000rpm if you plan on re-enabling the MAF. You don't have to try to hit every cell. That's virtually impossible. Focus on the ones you hit or can hit under typical driving scenarios.
3. Does copy and paste work for you? I have to manually change the ve table by small amounts, otherwise it’ll over correct. I can't find any leaks that might cause this. That is a requested feature (coming soon hopefully). Until then, you can use an application like Excel to adjust your corrections. Just takes an equation or two to tweak the BENs.
4. RPMs go down when I rev at a stop light – Throttle response isn’t that great at all either. What should I scan to correct this? Did you try some of the adjustments I made in the idle tuning post in the tutorial section?
5. Could a bad VE table being either too rich or too lean cause KR? High timing or lean AFRs are typical sources for KR. Too much fuel shouldn't cause KR.
Thanks!
