Post a video! There are only a few thing a that make me grin like a kid at Christmas, rolling antilag, and discovering chatgpt can 10x my programming ability, it is like the best assistant ever. Happy Sunday!

Datalog cam angle error. If it's more than a few degrees that is your culprit. Also excessively low spark timing at idle suggests an air leak. Check the simple stuff out first m also obviously do a DTC scan with Forscan. I haven't had a chance to check your logs so apologies if you have already tried this. If all of this is good then check your oil pressure. Low oil pressure to the head will cause the VCT to fail to control to setpoint. Heavy valve springs will exasperate this issue. If it is better when cold or with a thicker oil this leads credence to this theory. Also make sure your cams haven't skipped a tooth, this will make the VCT have you work harder. I'm not a mechanic so take everything I say with a grain of salt.

Fg it is possible. BA BF it makes the car drivability awful. There are already some threads on this if you do a search.

As much as we think a forum is a better place for technical discussion we do have a private FB group as well for registered customers. Please try to use the forum where possible however Facebook does have its place due to the convenience. https://www.facebook.com/groups/pcmtec/?ref=share

Whenever the ve of the engine is affected both need adjusting. Eg a turbo change, cam or exhaust.

Something else you could try is massively leaning/richening it during shifts almost to the misfire limit. This coupled with spark retard may give you what you are after. Eg try 1.2 or 0.6 lambda.

It's not even remotely possible. External controller is the only way.

The software is only part of the puzzle. You need the calibration files, bootloaders and templates that basically tell it how and what to do. The software on its own is not usually very useful as its designed in a generic manner for many applications.

Its done via Kline and requires special software which is not publicly available.

I believe Daryl actually had a BF tcm not an FG and was mislead. You need to get the TCM converted by someone like Whiteford. It's not possible using our software afaik.

Yes absolutely. You will run out of injector if the car is stock though.

The cruise control logic is fairly complex. There may be an auto up shift if throttle or load goes to zero. Can you log shift map, throttle, load, vehicle speed, rpm and oss on high priority when this happens? I'm sure there will be some development settings for this. Edit: These won't fix your problem but might point you in the area you need to go looking to fix the issue

Thanks a lot for this bill. Will get it sorted this week.

A few tuners have tried and all agree that it never really works. One with a big power zf (600kw) used a multitune and did it in one tune only for the drags. It worked OK at full throttle, but part throttle sucked.

The resolution doesn't have anything to do with it. It will still interpolate the timing and peg at the 1.2 load. At half throttle or low boost it will be less punchy than it could be if the tuning was optimised for the part load. Its possible you had knock control kicking in previously in the midrange and it wasnt adding the timing back until later than it could have. That could explain why less timing at 1.0 load means you can get more at full boost (what turbo and load do you have) Have you done a map trace of knock vs load on the previous map and the current one?

Make sure you do not turn off over boost or tmap protection as well. This will save your engine.

I don't think the system gain of an internal gate is similar enough to an external for it to work. I'm not sure how configurable the black box is, maybe if it lets you tune all the PID gains it would work.

That is good news!

The decimal places in the bottom left of the Log section. Have a read of the datalogger manual for more information under the help menu.

They require an external controller which is fairly complex, the external controllers likely need current boost pressure, desired boost and many other signals to be tuned successfully. I don't think they would accept a straight PWM input which is all the factory computer outputs.

No worries. Good luck!

We aren't actively developing any new firmware for the Falcon anymore. It would be possible but it would be at a huge cost which we couldn't justify. Using the built in torque reduction as you found is your best bet. You can adjust how much spark retard is commanded as well via the torque requestors, min spark ratio for torque retard and finally the min spark clip.

Can you try pressing the + button to increase the decimals. Or alternatively check what the units are, it may be set to seconds with not enough decimal places. Set it to milliseconds with 2 decimal places and you should see a meaningful number.

Base spark is MBT + any emissions or other adders. It will use the lowest value of all the different sources from MBT, BLK etc + the adders. Basically you can assume this is using MBT when it says base. Check auF2727 "Base spark retard for NVH", there are also a few emissions tables that subtract spark, these can come into play in some calibrations (Most have them zero'd). If these adders are active then it will likely report the source as base. It can also report base spark when coming out of oscillation control, eg if you stab the throttle in first gear it will trim the spark to try and avoid driveline shuffle. It will then ramp back out of this mode. You might have seen tip in/tip out as the spark source prior to it saying base. The intermediate value you can datalog for the various spark sources are. MID90840 Spark Base MID91036 Spark MBT MID91051 Spark Base for NVH (noise vibration harmonics) MID90837 Spark Base for Anti Fouling (zero'd out in all cals I've seen) Also have a read of this if you haven't seen it before.
