Tried the injector output and still in limp mode, scoped the output both with Motronic and VEMS, VEMS obviously has shorter pw because of bigger injectors that are tuned properly, couldn't get higher with Motronic than 1100rpm because with bigger injectors mixture became too rich.
Seems that we would need to configure boost_alt or some other output so that it would feed the pw of original injector despite the use of bigger injectors. Original injectors are Bosch 0 280 150 731: 201cc/min @ 43.5 psi (3 bar), however, factory FPR is 3.8bar so that makes them 226cc. 6cyl engine.
Here's Motronic load signal:
And here's VEMS load signal:
There's also output from Tiptronic to Motronic that is called "ignition timing change" which is used to request retard on gearchange (factory has it 5V on Motronic side that is pulled down during request). I would think I can connect it to VEMS input and configure ignition retard? Any tips how it would be best to configure?
