    I haven't been doing much logging or tuning at WOT with this setup so unfortunately not much to report. I will try to pick through what logs I have but as I recall the few times I've gotten into it...

    I also suspect it, times ten. In fact it's widely published that OEMs generally mock up the entire front of the car on a flow bench to develop their MAF transfer curves. Google: "helmholtz...

    Odd. All others in mine are 6mm exactly.

    I went up two drill sizes on #1 to 3/16". Hopefully it wont wreck the tune. I didn't see any other reason the left side would be getting less air than the...

    I've had some time to disassemble and clean things, and I think my oil issue was caused by the intake gaskets being positioned too far down on the front ports. When it goes back together I'm going to...

    Is the run flag logged directly by eehack? I only see engine runtime, and just assumed the AIR output was enabled in conjunction with the run flag. Unfortunately I didn't log any of my hard starts...

    Just wanted to report back that I've think I've made some progress on the startup tables.

    The LT4 cranking spark table didn't seem to solve any problems by itself. I'm currently still running it,...

    Curious what the 12680 multiplier is - the injector constant shows 27 lb/hr. I didn't know the LT4s got bigger injectors.

    They did get completely different heads and redesigned intake with taller...

    Interesting there's that many differences between the stock bins. On a whim I just tried the lt4 cranking spark table. Before this change pretty much all starts with anything under 0x50 in 2680 was...

    There really isn't anything new or terribly worthy of sharing. I did recently fix a problem where the IAC override would set it to 4 (steps) and not change if switched to step mode. But that might...

    I'll probably pass on testing until I'm done getting my tune at a respectable baseline - it's coming along really well so I'd rather not get distracted with other stuff right at the moment. I've been...

    I'll press on tuning SD with the MAF disable flashed. Hoping to have VE "close enough" by tomorrow. After that I may need some advice on the MAF pumpshot tuning.

    I'm not sure it makes complete sense to me yet but thanks for looking into it!

    I've already found by hand that 0x44(44) puts me 2% rich of target so that should be close enough. I was just...

    I just noticed your math on the base pulsewidth scalar - very interesting. Confounding actually. No idea how to pull the MSB and LSB out of a table value in a xdf definition.

    Looks like by scaling the table at 12691 I had 2s in the 80c and hotter rows. With the multiplier I had in 12680 that resulted in 2.7ms prime pulses. Not too short to fire the injector, but an awful...

    I'm shocked that the individual trims aren't applied during cranking because I've had it starting great and then reset the trims to 1.0 and it wants to crank forever.
