I've noticed my upper limit on KPA under ve table is 210, and under spark is 230. If I googled that right, that is over 24 psi. If I don't plan to run that much, can I scale the tables down to get better resolution for a little bit finer tune? I'm just not sure google did that conversion right.

Also, if someone has time, could you see if anything stupid jumps out at you with this tune. it's still a work in progress. Trying to get idle AFR out of the gutter, it currently idles around 11.0-11.6.

Thanks.

Relative to atmosphere. You measure from absolute zero. I think... I dunno

200kpa is something like 14psi.
Use the bottom table.

Yes, thank you. So if I plan to run around 18-20 psi, I should extend the tables to around 260 kpa to cover overboost, which would cover up to 23 psi.

Yes.

Ok, so I'd rather not make a new thread for separate issues so I'll just post in here.

Idle. I can't get the damn thing to lean up at idle. It always sits around 10.5-11.5. I did play around with idle VE and got it to lean up a tad, but it was unstable. It would idle up and down, sometimes stalling.

I guess the next thing is called lean tip in? I played around with the accel pump, and sometimes got it better, but would idle up and down again. I got it so it doesn't go lean anymore, but it would still be a delay from thottle application to actual revving.

I did fix an issue where on very light throttle it would sputter and spit back, I don't know what I did, but it doesn't do that anymore. Probably something to do with the accel pump.

Otherwise, the reason I did some logging today was because at full throttle, in 3rd - 5th, once you get above about 4k revs and the turbo spools up fully, I can feel a sort of pulsing. I was thinking it was timing bouncing up and down, but I'm not seeing it on the log. You will have to forgive me on it, it was wet out and I was modulating the throttle so I didn't spin the tires. (**** tires)

1st one around 2408s is a good pull.
2nd one is my lean tip in issue
3rd one is a quick 2nd-4th pull

Are you using ECU boost control? Your boost drops like a rock at 5k rpms.

no using manual, I have the ebc but can't get it to work right
