Re: electronic throttle body control ETB

The biggest issue seems to be within the first percents of Throttle opening. It looks ok when testing, starting the engine changes that. It's to slow and/or "nervous" around idle if that make any sense. Maybe that could be solved by a target table like Link, or another table to make it non...

Do you have an oscilloscope handy?

Probe the 5v and 3.3v rails while doing the thing that causes that to happen. I bet you're having power supply issues. How's this setup powered?
I think you are right.

The issue is seen right when doing what pull most amps thru the H-Bridge.

Re: PNP ECU for Vw/Audi ME7 #51

Sure it's not your power supply?

The H-Bridges has separate caps and diode, so I dont think its there.

Is it the same with both H-Bridges?
Have you tried with UBHR disconnected?

Re: electronic throttle body control ETB

With most of the settings I have tested with TPS "hangs" at around 20% at the way down when releasing pedal.

Playing with a non linear bias curve solve it, but hard to get correct.

So a automatic setup would be the most accurate I think.

Re: electronic throttle body control ETB

It should be just test-button.

I have got it much better, it seems to be all about the bias-curve.

I think it's related to my non-linear analog inputs.

Chech these settings:

Just a theory, the initial ETB setup could be done automatically with just one routine/button ? 1. disable pedal position/PID 2. store the tps rest position 3. increase negative duty until tps adc stop counting, store min. 4. increase duty until tps stops counting, store max. 5. increase negative du...

Verbose is a common word in Linux land. It simply means to display more stuff in your error logs and similar.
