Perrin MAF scaling 2.75
I've been working on a MAF scaling since installing the Perrin CAI and tube using OFT /Romraider/Vimsh software. LTFT have gone from averaging -7 to just <+-1 as well as STFT averaging <+- 1 albeit seems to be a little leaner than LTFT. So I think data logging will show more as the ECU learns better, but I was curious what more trained eyes thought. The OL pull isn't exactly ideal starting a little high rpm and might have been in 4th gear but I think it reflects what's happening pretty well. Curious on thoughts, wasn't looking to change timing just yet but whether the MAF scaling is looking pretty good.

yes maf scaling is very good, good job
turn down a bit timings after 6400 and those random knocks triggering AM |

seems good, those heavy knock corrections at high lownlow rpm you d wanna reduce them a bit

I think that's from be going a WOT at low rpm at 91 octane gas?

of course, but you might want to have it tamed down anyway somehow, those big correction down low at full gas seem like Low speed pre ignition and that is destructive over time

the knocking is due to lean not enough fuel on e73 ??,

Man, why you keep writing 91 octane, if you re E73 at the mom, i got super confused :P
you still have much DI headroom in that knock zone, reduce PI% and knock will ease and/or make it richer, it seems to a bit too lean the target Also DI seems a bit maxed out after 6000rpm, you may want to augment PI% at higher rpm specially if you get real E85 in your tank Last edited by tomm.brz; 05-27-2020 at 04:43 AM. |

looks good
but you have to raise Port injection at high rpm keep DI opening time under 6ms preferably lower so to have headroom when ambient air is cold Ignition end of di to spark is too short, keep it higher than 2ms because if gets cold or you go e85, it starts misfiring around 1ms |

That increase IAT from oil cooler messing with fuel trims, but man this thing stays strong in the heat now. NO power fade with heatsoak via butt dyno. E85 log from earlier yesterday.

First Ecuteck Log
I made the switch from OFT to EcuTek. This is my first log using the Ecu Connect App.
I am running the SBD 400X with an ECBS. Have I logged all the correct data points? https://datazap.me/u/randomthoughts/...&data=14-23-24 |

Did some datalogging to try out VirtualDyno. Car feels really good, I've been on the same tune from Sasha at OnPoint Dyno for over a year, with only an update in May to increase the rev limit to 7500rpm (from 7200rpm for a bit more room on circuits).
Should I be concerned that my Advance Multiplier is defaulting to 0.7? As far as all the other data points, I don't see any issues. https://datazap.me/u/jbezugs/3rd-gea...a=5-6-16-27-28
