I really love this ECUs, so I want to put it in my project cars.
My biggest issue is TB, TB is standard on cable with TPS
I can use TPS like pedal position sensor, for torque demand
I will put progress here, if anyone have some idea fell free to write.

There is no reason to use cable throttle, even with a standalone ECU.
It's a better idea to use a standalone in the first place though for a project car.

I know but I like ME7, and want to learn more, my daily have ME7 but I use it every second and don't have time and will to work on it. So I need some car to try new things on ME7
I could also put electric TB, but for now I will try without it

It's not going to work at all. And there is nothing to try, because by the time you chop off enough shit in ASM to make it work, you're not going to have torque model or anything else.
Forget it.

And what about use Throtle pedal position and TPS, only put resistor for TB motor?
Make KFPED 1:1 and other things that ECU will not make DTC if want to close TB

u can always leave the wired tb hanging somewhere in the engine bay, just so the car thinks its still in use, and keep ur cable one in use.

After good sleep, prj is right. There is zero reason to not use Electric TB
Idle would be pain in ass, transistion near WG crank pressure and so on and so on

Yeah went down that road 12-15 years ago. Worked like shit, waste of time. |

Besides if you wanna do this you can with cwmdapp but it will not be better than OEM obviously.
You can also keep torque control selectively but some elements will be disabled.
There is also a map to make the pedal 1:1 to opening or whatever ratio you want. Did this back in the day when I turbo'd NA on original ecu.

I have run into probles with ignition firing order.
I run without CMP but for some reason I didn't get it running on all cylinders.
I know that 4 cil ECU without CMP won't start first time, i must turn off ignition and start again
But V6 start every time without CMP does this ECU go in batch fuel and waste spark or?
Edit: I checked with osciloscope and it does not work on waste spark, strange beacuse it start same with and without CMP

cwmdapp is only for fixed WGDC? Or have something with TB? |

CWMDAPP contains multiple bits/switches for the configuration phase not just static wg, but static timing, static TB %, or TB % from a map based on pedal etc. Like I said you can disable the torque based throttle control and have the TB open by a map which you can set to any rate you want. You can also keep or disable timing intervention. Set B_FPWDKAP to 1, and the map is called FPWDKAPP, you can set it 1:1 if you want. It will be weird but if you want to test it you can. |

Yes, but be aware that you are likely going to hit torque montoring 2 with this unless you disable it completely. You can effectively strip ME7 back to nothing but running it 24/7 like that loses meaning, thats why these functions were intended during the development/calibration phase. |
