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.

Hi no problem to make 8800 with oem spring

repost your latest calbration and datalog james buddy ill have a look.

nevermind , lol. heres an update buddy. keep an eye out for knock ok , your ignition map had some wonkyness to it , lol , so i somewhat revamped it and well tune from here.

here is the datalog for the tune you recently made. the first pull was in 4th but couldn't get to redline in time, the 2nd pull was made in 3rd. I also uploaded the tune in-case you misplaced it. thanks again

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.

i tried doing a pull from 3k 2nd gear on the new and previous tune and the new tune pulled way better than the old. anyways here's the datalog

i also attached the tune incase you misplaced it. thanks keto for the input as well.

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.

alright here's the datalog and the tune. cars feeling way better everytime. thanks again cranny

here you go buddy , your WOT is as tuned as its gonna get this route. one more WOT datalog please. would you like to part throttle tune it as well?

yes sir, part throttle as well. ill get that datalog here soon.

btw should we smooth out the cam angle maps? for example from the k20a-itr.kal

low speed cam angle


high speed cam angle

datalog and tune attached. got 1 knock at around 8300

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.
