Hello,
I'm tuning an AP1 S2000 and I'm having an issue with ignition timing dropping at the VTEC crossover. The tables call for 29° on the high cam, but I'm only seeing 18° in my logs. It will slowly climb util red line, but it's no where close to the table. I've also tried running really conservative timing with the same results... As soon as VTEC engages the ignition drops to 18°. I've checked the logs and I'm not seeing any knock, but I know I'm missing something.
Amy ideas?
