7.3 Godzilla throttle closing uncommanded
Like the title says, I have a 7.3 Godzilla and 6R140 out of a 2022 E450. Now in a bronco. When at WOT the throttle closes on its own starting at 4500rpm. Every time it closes with the same profile. It ramps down to 80% at one rate and then slams closed to 40% quickly where it begins to level out. I'm not very experienced in ford tuning so its very possible I've missed a parameter. If anyone cares to take a look and tell me where I did wrong it would be greatly appreciated.

Smells a lot like the temperature based engine speed limit.

I've never seen ECT over 200. CHT has been up to about 215 during a hard pull but immediately comes back down. The temperature speed limits don't come into effect till about 245. I suspect its something with the ETC FMEM and stuck throttle modes set, but everything I've looked at seems to be within specs for these not to be on. They are always on from the moment I start the vehicle.

Well how certain are you its not just in the first column of that table until it meets the criteria to jump over to breakpoint 2?

Well it says engine speed limit, its closing at 4700 and there is a hysteresis=200 rpm so everything goes according to plan.
Setting only Cutoff to 5800 wont raise your overall engine sped limiter. Not to mention trans side is set in similar fashion.

Veeefour, I see where you found the engine speed limit on the transmission side, and thank you, but I don't see where you found it on the engine side. I still have the speed limit after fixing it in the transmission table. Any help?
