Has to be more than just throttle V to dictate PE

[coanan]

Just add all the channels that are related to the accelerator pedal, particularly the accelerator pedal voltage. There will be a few of them. You are logging the throttle position (%), throttle position sensor (V) and commanded throttle actuator (%). These are not to be confused with the parameter regarding the accelerator pedal.
In the log you supplied I can only see the "Accelerator Position D (SAE)" (%) channel.
Also make sure you increase the logging rate to 10ms of these channels before you start logging otherwise the data rate becomes to slow and nothing lines up nicely.

From the data in the supplied log, it seems that OL is triggering correctly and the mixture is richening up as per your wideband data.

Since I can't get a log to look right.

Trying different things with same result.

Before stroker. going into PE fine. NN was enabled then to. WOT pedal thresh was 1.45

I must be missing it, but where in these screenshots of your logs are you seeing anything relating to whether you're entering PE or not? Which PID are you using to make this determination? The closest thing I can see in your list to something that would tell you you're in PE or not is the Equivalence Ratio Command PID.

And was post #23 supposed to be showing a successful moment in entering PE from before doing the stroker setup? Or is that another screenshot of its current situation?

Well I'll admit I'm not the sharpest one when it comes to reading logs. I'm just throwing $hit at the wall and seeing what sticks I guess.

Watching for stft to go zero. Isn't that the point of OL?

post 23 showed AFR where I thought it should be when in boost, it does go into OL in that log, just not at the point of pic. That was with the 6.4, smaller cam, and same SC.

Think I'll just give it up, get Whipple on and take it to a Pro.

Continuation of same log in post 23. Log is too long, site will not load and I can't get it to show everything I'm logging when loaded anyway. Not sure why. You see PLX at bottom, my wide band, 11.24 and 11.52

You need to be logging fuel system status to tell you when you're in CL or OL, and the accompanying mode of each (ie it will specify CL - Normal vs OL - Not Ready vs OL - Accel, to name a few).

Your STFT isn't a great indicator of when you're in OL, since occasionally it will cross zero while still in CL. The better indicator that you do have logged that helps to tell you when you're in OL is the commanded EQ. Anytime it's at 1.00, you're most likely in CL (except for when you're in warm up mode and still commanding 1.00). Probably more accurate to say that anytime you see 1.00 EQ, you're definitely not in Power Enrichment.

I think I might have an explanation for you.
Recently (start of this year some time) HPT did some big updates/changes to the scanner and some of the PID names/values were inadvertently switched around. This was an absolute pain in the neck for us with scanner channel lists and layouts that we developed over a few years.
Previously and for many years on FCA vehicles, HPT had the "accelerator pedal position" PID as the variable that logged the actual accelerator position voltage, which corresponded to the WOT threshold voltage (among other things) in the tune. This variable would range from 0.000V to ~3.84V.
Now if you log that exact same PID on updated scanner version, the voltage range is vastly different and does not correspond to the WOT threshold in the tune.
The parameter you should be logging now is the "relative pedal" voltage. If you keep logging the "Accelerator pedal position" as previously, it will show a higher voltage than it should. Therefore, you would think its past the WOT PE threshold when its actually not.

So in summary you should alter your scanner setup to log the "relative pedal" voltage instead of the "accelerator pedal position" voltage in later versions of the VCM suite.
You will know if you are logging the correct one if you start logging with the KOEO and push the pedal down, it should range from 0V to ~3.84V.

Conventional wisdom would say yes, but this is not always the case as I've noticed with FCA and some other OEM strategies.
If the cells prior to entering OL are on the lean side then the STFT can be carried over into OL. I've seen this happen quite often, which can mess up the OL fueling. Therefore it's not a good indicator of whether you are in OL or not.
2 of the most reliable sources to determine whether the PCM is in OL or not is the "Fuel system status" and the "Commanded EQ ratio". The fuel system status will switch between "CL-normal" and "OL accel/decel" values. Whereas the commanded EQ ratio will stay at 1.00 when in CL or <1.00 when in OL provided your PE tables are populated.

Thanks all for the help. I compared the old file to the current one and made changes to current. Going into CL/PE right before boost starts now. Seems a little rich, maybe getting fuel from somewhere else.

0020B reflect changes 0020A to compare and see changes made

Need a 2.5 pulley and a TB adapter for the 95mm TB

[coanan]

Well all the ranting I did about throttle body adapters was for not.

The snout is drilled and tapped for the Hellcat TB.

Doesn't look the best with part of snout uncovered and not much of a sealing surface.

Outer edge of TB 114mm, Whipple shout 108mm opening.

Just need a gasket and the Meth kit that includes the Hellcat inj plate may come with in.




5.7/6.4 TB adapter plate

SmoothBoost came through. Sent them by bypass and they made a bracket.




SmoothFlowPulleys also came thru. Sent them my 3.5, they made a 2.5 and 2.75
