Re: Esp32 Tunerstudio Wifi

Depends if you have the paid version of TS or not, I believe the free version is limited to 15hz logging.

Re: EFI Part numbers and sources READ ME

Would like to correct, it seems only the US pickups use the open sensor on the GDI, most normal GDI engines stick with the small hole version.

Re: Hello from Norway! VW Beetle w. 3D printed intakes, 2x DBW and staged injection

The long term solution to this may be that we make some modules that connect via CAN that have some additional not time critical analogue inputs. Thus we can expand some of the ECU inputs via CAN.

This is a long term goal though.

99% correct pinouts for the older BMW ECUs.

Your looking at 35 pin motronic.


Edit - try this for the stock ECU, its M20 but 99% correct. https://www.e30zone.net/e30wiki/index.php?title=Motronic_1.0

Re: 1987 BMW 535is Turbo

Sounds good. Weird that it has the sensor on the front crank pulley already? The gap was massive though and the pulley itself has no cutouts. Will swap to 60/2 From what I remember of the old system it uses one wheel with constant width teeth to detect RPM and one wheel with a single mark for tdc, ...

They used flywheel sensors for CPS, forget about them and use that 60-2 wheel.

One thing that has just come up is possible a dodgy coolant sensor making for a hard first start - Solution was to temporarily flat map the CLT fuel corrections just to be sure that it was not causing issues with the first start up and fix the CLT after we knew it was all working otherwise.

Re: 1998 BMW V12 engine M73 #55

Might be able to clear up some confusion here, the injectors are "air guided" so they use a cushion of air around the injection spray to help prevent port wall wetting (and thus emissions during transients), I believe they are not using any kind of pressurised air unless they were previous...

Is there something special about the TPS?

M52 TPS is reverse signal (lower ADC open than when closed) and RE has been working fine with that for a long time.

Re: microRusEFI

Just as a confirmation, I tested the AUX lowsides on AV 6, 8, 9 and 10 tonight and I can confirm that all but AV6 will work as a lowside out of the box. AV6 needs a zero ohm resistor added to make that one work but it also functions. So if the AUX AV reuse pins are selected then they 100% work. What...

May have just been diagnosing a non-start log that is hopefully due to a non functional fuel pump.

Your looking to run a 6 cylinder right? At this time the only proven way to run a 6 cylinder on an MRE is wasted spark and batch injection using the standard 4 Inj and Ign outputs.
