That one needs to be out of the way as well. The table I showed is the exhaust counterpart to what HP calls ECM 38167 (I'm sure they have it mapped on some other platform, just not this one).
I'm...
It's missing, I defined it myself
I stand corrected, found it. Exhaust Cam Phase Limit.

OP is disabled in the MP configuration, so the torque, spark, SD, etc from OP are not used. The VCT Schedule is in Optimum Power, which means the angles should be coming from OP, and the weight's are...
OP on this car is -50/10 until 5k, then the intake cam tapers off. OP (Poster, not optimum power) wants to keep retarding the exhaust past 15-16, which I don't think will pick up any power, but he...
Correcting myself. I quickly took a look at the limiters, I don't see anything preventing +16 exh VCT. On the dyno I started to lose power as I approached 90 degrees of throttle angle (the engine was...
We dont use OP on these, and it isnt typically enabled. The issue is that half of the VCT limiter tables are missing. But I dont think OP will pick up any power moving the exhaust cam
I'm not necessarily defending this company but it also seems like your expectations might be a little unrealistic. With large companies, your request that should "just take 10 minutes" gets thrown...
At least its safe to say that our jobs are safe from AI takeovers for the time being
Bruh this is ChatGPT lol
So with this ECU being MAF based, I'm not sure that would work. I had the thought of integrating the MAF into one of the runners, post throttle. I'm not sure it would appreciate the intake pulses...
So on a whim I designed an ITB manifold for a 2L GDI Duratec. I'm 3D printing the prototype as I write this. I'm now asking myself if there's any way to force these ECU's into some type of MAF-less...
For clarity, I wasn't mentioning the rich/lean thing for the sake of being the "actually" guy, so I hope it wasn't taken that way. I was just offering a different way of thinking about it.
...
You asked if multiplying DD by 5% is the same as changing the pedal characteristic by 5% and then gave an example where that isnt true.
We agree on the second point although the pedal...
Rich and lean are usually terms used relative to stoich. It's easy to think about alcohol fuels as having a "richer" stoich because it requires more fuel volume to achieve a stoich mixture, but it...
You've made a 10% change to your pedal characteristic that only produces a ~7% change in torque request. If the driver demand table was directly proportional and linear then 10% would be 10%
You can modify driver demand within its own boundaries without touching the torque model (ie. Dont exceed the upper and lower limits of the table) and would/should produce the same effect as changing...
Forscan can return it to stock
Just to qualify my statement, I think it's good if you can make the torque model accurately reflect the actual torque the car is making. It just doesn't seem to directly backfire on you (ie. Throttle...
The torque model will stay plausible as long as the correlation between torque and inverse stays the same. You can run direct port nitrous and the torque model won't really be affected even though...
I understand now, thank you.
Assuming an oil temp inference model, here's how it works in my world, I'll assume that it's at least remotely similar for Coyote:
An initial oil temp value is...
I'm still a little confused on why we can't differentiate between slight discrepancies in commanded vs actual and massive discrepancies in the 10-40 degree range.
I'm not convinced that because a...
I'm less concerned about the 0-3* movement in that log. It's the sudden phasing to almost 10* above 7000RPM that causes issues. If I slipped the exhaust cam by 10*, it wouldn't be able to return to...
