Many thanks Adamw

another log.
I try to set the starup offset to 0 but TPS still around 5%.
you can see in this log that when I put a little throttle, the RPM goes up and never return to idle, I had to put throttle again and afer the rpm sometimes goes down to idle, but not every time.
If I desable all idle functions, TPS go to 0% and engine stall quickly.

Hello, thank you for your answer.
Idle is much better now, you can find the log attached.
The car is on neutral in my factory, engine is new and I wait to solve the probem before going on dyno to make the break-in and mapping.
The error accumulator is now solved: I put 91% in APS(100%) cell because with on WOT the throttle body open more than 90°
So now I put E-throttle 1 Target max value to 91% (have to valid this on dyno)
I still have 5% TPS in overrun:

Hello,
I'm Sebastien from France. I'm a newbee on the forum, but I'm a old Link user, I played with all versions of the link on my cars (G4 G4+ G4x vipec V88 ...).
I've build a rally car for one of my best friend BMW e36 with M42 engine and lot off bespoke parts:
Engine and ecu are new.
-stroked to 2.0L
-Full ported head
-3D printed inlet manifold
-Seq gearbox
-68 mm DBW bosch motorsport throttle body
-...
It is the first time I use a DBW throttle, I need help for 2 on two points:
1-I have TPS & APS error accumulator, I try many differents setups but nothing change and I don't know why
have a look on error accumulator file ( log maded with engine stopped)
2-Impossible to have a correct Idle: I don't understand why the TPS never go to 0% when I'm off throttle a hight RPM.
TPS is locked to 4-5% and sometimes, the RPM never goes down.
If I decrase base idle position, the engine stall.
I tryed with open loop E-throttle + Ignition idle: It reach Idle target, ign° make jump from min to max clamp value, but engine sound like a running on 3 cylinders...
If you look at ign map, I need to remove Ign° in RPM cells, without this, RPM never enter in Idle mode
If I leave a std Ignition map & off all idle function: TPS goes to 0%.
I Put 0.5% min in E-throttle target, below 0.4%, Motor DC % increase a lot, and with 0% it goes on limp mode.
Can you explain me what is the dashpot setting ?
I Attached Map & Logs in the post.
Thank you for your help.

Hello,
I'm searching information about the wiring of the G4 plug-in Ecu for BMW e36.
A friend swap engine from L6 2.8L to L4 2L according to F2000 french rally legislation.
So, I'd to build for him a new engine loom
In the user guide, there is the a partial wiring: you can find only 1 GND for both ecu supply and sensor signal.
In the BMW Electrical manual, sensor GND existing (pin44): but not sure it is used by the Link....
If someone can help me...
Thanks
Sébastien

Hello,
test ok !
Finnaly,
-I've adjust base position idle for each temp
-increase E throttle integral factor to 0.5
-adjust dashpot
Now we can go to dyno for break-in and tuning session.
Many thanks for your help
