Yeah I think I'll pull it up at that. Running 20 degrees @ 170-180kpa seems the stock exhaust is holding it back due to back pressure. I'll post a log later as I've been tuning it in open loop, the o2 was giving weird reading. It shows 12.5 (what I'm asking) then at about 3600rpm it falls to 11.5 in every log but the actual is maintained at 12.5. I'm thinking voltage is odd but haven't logged it.

Stupid white magic baro lol.

Haha I know!!!! But considering what it is it did well. Only up side to more back pressure is it makes a little more boost lol. Shame it goes nowhere haha

so ive got a weird thing happening with my target AFR, all my tables are set to 12.5 when the map sees above 100kpa but in every log ive taken it dips to 11.5 at the same rpm (3600). is there a compensation table somewhere im not seeing? ive done all the dyno time in open loop so it hasnt effected the tune but im guessing when i switch closed loop control on again it will influence the fueling.

Ive looked at that log maybe I've misread, It's targeting 11.5AFR. That's open loop regardless of any settings. Open loop is only when targeting 14.7AFR.

There's a table for boost AFR targets as well id say they're targeting richer than 12.5AFR? I havent seen the BIN to check.
