Project is customers race car, BMW E92 with S54B32 engine. Factory harness, plug and play adapter and S54 VEMS ordered from webshop with double-vanos and ETC support.
Problem is oscillating throttle when TPS is connected, when disconnected oscillation stops (TPS shows ~60%) and obviously motor opens throttle only when pedal is pushed past 60% and then it opens to full.
All the connections have been verified (polarity of TPS/PPS GND and 5v), analogue input pins etc. Should TPS2 (on the throttle motor) show ~4.8volts when throttle is closed?
Here's current config file (please review ETC part and VANOS part): http://www.vems.hu/files/PeepPaadam/BMW_S54B32_pnp.vemscfg
And here's video of the issue: https://www.youtube.com/watch?v=487Q0X98_5I
Please could you take a look at this as the 1000 km endurance race is already after a month and we really need to do some testing too.. Thank you in advance!
I have working config for that engine, contact me to my email damir.muha@gmail.com Tnx I sent an email.
The config I used was in fact from working car (not mine though)..
