Car is a stock engine ap2 with a CTSC kit @ 10psi.

First pic shows low cam timing.




Second pic shows default Hondata supercharger tune



I'm here because the car feels a touch soft on the low cam during normal driving. I've tuned other systems before (didn't make this tune)

I'm considering maybe splitting the difference between my low cam timing and the canned Hondata stuff up to 4k. Thoughts?

On further research, it appears that the "stock" map has very similar low to mid throttle timing to the SC map. Mine seems unnecessarily low.

You aren't even showing us the boost columns. I don't know why you would be pulling that kind of timing on low cam non boost.

I'm not worried about the high cam. It's correct.

Post a datalog cruising on the highway at ~65 MPH.

My main concern is > 50% throttle below the vtec change, say 2100 to 3500. It's pretty soft.

Stop guessing. Get it on a dyno and tune it.

It is dyno tuned. I just feel that there is low cam power still on the table and I'm looking for opinions.

Find a stock ecu timing curve and copy it. As memory serves the hondata tune is closer to where you want to be if not entirely. Its all under vacuum so you will be safe duplicating it. When you run that map does it feel snappier? That should tell you. Probably improve your MPG a little as well. However I will tell you from experience, that as early as 40% throttle the supercharger is pushing boost, and obviously more as the rpm climbs. At 50% throttle and 3500rpm you are probably right at that threshold or a little past maybe making 1/2-1psi. So account for that.
