As per usual, life gets in the way of hobbies... but I'm finding a little bit of time to chew on this Thanks for your reply Mituc, your comments make sense and I have decided to rework lots of tables including finally stepping into the load tables rather than leaving them at 3 and playing with WGDC ...

I appreciate all the feedback and feel like I am learning so much. Your responses have really been invaluable. This has brought up other questions but in the interest of trying to keep those questions more easily searchable, I have set up another post titled "commanded ARF not matching AFR tabl...

Hello all, I am continuing my self-tuning “journey” and once again come to yall for help. In my tune, I have set the WOT AFR to decrement to .782 (11.5:1) by 3k RPM and hold throughout the run. When I do a pull and take a log, it seems the ECU requests an AFR value much richer than .782 and don’t kn...

Great info! Could you explain a bit more about target air fuel ratio? Is there a "rule of thumb" we can use as a starting point? And what should we look for if we were to deviate from that value (just read plugs? Or is there more we can look at from the data logs?)? I assume increased load...

Without aux fuelling you will not have fuel for more than 25 (maybe 26) PSI of boost, and that's with revised fuelling tables. On a big turbo setup you can chose the tapper up boost strategy instead of tapper down like for the tiny stock turbo. So you can set your boost limits to 22PSI at 3500rpm, ...

Follow up: I installed a 3.5 bar MAP and updated the MAP calibration values. The car felt a little better, it didn't feel like I was rear-ending someone anymore but it was still cutting out a bit when in high load, high RPM scenarios. After more research, analyzing logs, changing parameters like fue...

oh snap, I wonder if thats why I was seeing WGDC drop in the higher RPM before setting BCS DC Adjustment - Decrease from -100% to 0%... more testing required!

So keep in mind that all the boost tables work with absolute manifold pressure, not actual boost. Absolute manifold pressure is Boost + Baro. Oh! that makes sense! I was thinking this was a "gauge pressure" reading not "absolute pressure" reading... wow something so simple... th...

Thanks for the quick response, This tune is in progress and many parameters were changed in an attempt to troubleshoot the aforementioned issue (which i suspect is fuel cut) including: -load targets and load limits = 3 across the board -Overboost Protection Throttle Reduction set to 30 across the bo...
