Do you see at the VTEC point (5300) where the torque rises sharply? That is a means that the VTEC point is too high.swwifty said:
how could I possibly pick up more midrange if my A/F ratio is pretty much perfect? look how flat the A/F ratio is. I don't think I could lean it out anymore.Hondata said:Do you see at the VTEC point (5300) where the torque rises sharply? That is a means that the VTEC point is too high.
If you have good headers the VTEC point needs to be around 4000 rpm. You'll pick up a lot of mid range if the VTEC point is dropped and that area tuned.
Your Mugen ECU could probably be upgraded to a Hondata programmable ECU.
what hondata rsx dyno doesn't have a jump in torque like that? I haven't see any customer dynos that dont look similar to mine.APEXiTypes said:Hondata said nothing about your air/fuel. If you look at a Hondata rsx dyno, there is no "jump" in tq or hp, not like yours anyway. All he was saying it doesn't look like 5300rpm in the best VTEC point with that tune.
For the most part, your hp and tq curves are very smooth, but would probably become that much smoother with a even lower VTEC.
I hope I got that right. Im sure Hondata will correct me if Im wrong.:nervous:
