I just got back from the dyno with the Accord and the Hondata work flawlessly. We were able to get the car tuned really well but I had a couple questions regarding tip in mainly. What are the max negative tip in values that I can set?
The issue is when shifting at full speed the engine experiences a rich condition (11.0 AFR) for a moment which causes a bog then it picks up. I tried setting tip in to -15% but it didnt help much.
Also, is there a way to set VTEC at a lower rpm once it has been engaged? My concern is in between shifts I find that it drops out of VTEC and I need an extra 300rpm to keep it engaged. But changing my engagement point any lower than 5700 is not ideal for hp. We tried 5400rpm and there was a big dip in the dyno chart. Hope that makes sense.
I tried the VTEC boundaries but that wasnt the function I am looking for.
There are no other options for VTEC. There is no difference form you accelerating from a stop and engaging vtec and shifting and engaging vtec. YOu either need to change your gearing or rev the engine higher.
Tuning full thorttle is only one aspect of tuning. PArt throttle needs to be tuned as well as making sure that there are no driveability problems. I would contact the tuner and have them go over what they have done and show them what it is doing.
