Do you have uprated valve springs? 8800 is not very safe on K20a2 engine with OEM valve springs... i'd say 8600 is sort of safe limit for OEM springs.

Looks like i wants more cam angle 3000-4000 and 6500-7000 to me. 35 in both spots looks about right to me, but Im not expert.

Also I would recommend fixing the ignition dip around 5000 where it dips to 27 and making it a smooth 28 across.

Oh and lean out that spot at 7400, and you should be golden. Also it looks like VTEC would be better about 100rpm lower to me.

id like to know how you would suggest it needs more or less cam or where ideal vtec engagement should be without a dyno readout , lol. your better than me if thats the case , haha

i added some cam angle to the low cam , see if it likes it.

please feedback how the car feels andrew.

here you go buddy. the ignition seems to drop to 27 shortly after entering vtec , even though the map is telling it to run more , have no idea why. see what happens on this datalog and if it does the same thing well have to diagnose it.

cam angles are fine. more than a couple differences between a k20a and a k20a2. WOT wise , a dyno is needed to tune any further.

first is the updated map and under it is the map i want you to load on for part throttle tuning. make sure its in open loop , at least a 20 minute datalog , vary driving conditions.
