Here is what mine looks like.

Mine has folders under it like the ECM. Maybe the software is not recognizing it. You might try a read entire with the new software vcm editor and see if it recognizes it.

Figured this out at least in my case. You have to log fuel pump commanded duty cycle under FSCM not ECM. The one under ECM always reads 99.6%. fuel pump duty cycle under FSCM is the one that reads...

Huggins OS is the same as mine. Wonder what fuel pump setup he is running? The stock fuel pump or FPCM seems to be what's screwing up with mine. Pressure dropped almost instantly down to below 30...

Thanks. Do I need version 3.7 to open that? Won't open with 3.6

Sounds good to me. Is this what you need?

main operating system: 12653669 does not work. Issues at 4000 rpm, fuel pressure drops below 30psi

I seems like GHuggins is the only one that's got this to work.

Yes I realize I don't "need" to use these settings. Injector gain is obviously causing issues though. If I turn it off the car runs perfect up to redline and fuel pressure doesn't drop like a rock at...

Tried this on my ZL1 and did not work. Car has minimal mods: Lungtubes, JLT intake. All I did was enable 'injector gain' then changed values for cyl# B & C to 1.02. At 4000 rpm it cuts out, goes lean...

I't may be working in one of the 3.7 Betas, but I haven't tried. Maybe someone can let us know.

Same problem here with V3.6.26. Fuel pump DC always reads 99.6%

I'm using the 30-0300 connected via mvpi pro analag. Seems to work well and fast. Not much lag. You can see it follows the B1 o2 sensor. that's where I have it installed(drivers side). I don't have...

You may need to go even lower. Check out these stock tables for my ZL1. 61 mv at 0 & 8.

I may be wrong on that. It may only use the cold offset table for the first few seconds after startup. Maybe somebody who knows can let us know.

Yeah that's the same file I pulled. Remember you have to add the value from the 'cold offset' table. 450+100(183.2 deg F)=550mv.
The 250/675 high/low is just the min/max allowable.
That's how I...

Actually looks like they switch around 525-550mv. I was looking at my stock 'cold offset' table.

Good idea on the ZR1 settings. I think I'll try the 'O2 rich/lean' mv settings as well. They change with airflow mode and ECT. Mine are just set at 450mv. ZR1 settings are at 600mv at cruise speed...

Yes, that's what I think also. At whatever airflow mode you are at, say 8 (32-63lb/hr), the pcm uses airflow mode 8 values in all the charts. If you are at 32 (~240lb/hr) it uses mode 32 values in...

Ok. I see exactly what it's doing now. Dx always = 1, not 250ms or whatever time in the slope equation.

So in my example above:

[76.156.slope(250)]<1

tps at time = 30%
tps @ time -250ms =...

Trying to set up the slope filter.
How is the slope value actually calculated?

Say for TPS(commanded throttle), You had [76.156.slope(250)]<1

tps at time = 30%
tps @ time -250ms = 29%...

Helped my ZL1 also.
That going lean on decel makes it hard to tune on the street. Skews the data lean.
