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

What's the serial number based on? MCU serial?

PM me if you don't want that out in public.

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.

Great news that its all up and running, did you solve the on board USB issue or do you still want me to send a new usb port over?

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

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, ...

Sounds like this is an old pre-1.1 motronic.

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

So I took a bit of time to get around to looking at this but went through all posts and made a few notes, apologies for the long post. If RPM is above hard limit, cut ignition and injection If MAP is above boost cut limit, cut injection # Can this also be supplemented by setting a max position for t...

0.5.3 is the latest well tested revision.

Are you using the automatic idle? As in not the fixed idle valve position?

I think this is related to an issue we have seen with the miata before.

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. Also som...

This is your missing piece of the puzzle.

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...

In the current case I do not see how we would have space for it. There is not 1 square cm of the current MRE that does not have functional circuits on it.

Huh, weird.

Well I will give it an update and confirm if the board wakes up with just frankenso power.

Sounds like this is an FAQ thing.

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.

Ohhh, ST170/focus SVT, previously people were disabling the VVT to use OMEX etc.

Good to see you managed to resolve this, I have moved this to Hardware as it was a hardware issue.

@Andrey - Is it worth me checking the pigtails I have here?

Just to update on this thread, AZM now has his MRE in his hands and ready for him to begin his rusEFI adventure.

Given his skills we should see him starting a car up over the weekend right?

Welcome to the mad house.

Something that has just come up, checking the fuel pump is running is really worthwhile. Fuel pressure - record value this is last, learned that the hard way a few years ago when I set the shop on fire because I had the fuel pump on and an injector wire shorted and filling the exhaust system with f...

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...

Something that has just come up, checking the fuel pump is running is really worthwhile.

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. The VNLD5090 is pretty untested as far as I am aware, they were added on 0.5.2 and I believe have not been used for any...

To give a more positive update to this thread we have assembled a prototype DIY ion board based on a design MCK117 produced and have tested it using an R50 mini wasted spark coil connected to an MRE. Result was no magic smoke escaping after 50+ sparks and a trace captured on a scope that was nicely ...

I would like to make a note here that the 2002 paper on diy ion sense is fundamentally wrong in many areas, at the time of writing it seems the author did not understand either the fundamentals of combustion timing or the nature of the signal being sensed. A quick Google of it also brings up the thr...

The comment about using the bench test is a good one, I had to do that recently to figure out the wasted spark wiring on a car I was struggling to start had been done wrong so 1 was 6 and 2 was 4 etc etc.

That's a good one, "is there fuel in it?" is one I see too many people, right up to professional level get wrong. I think my first tip would have to be "make use of the bench test functions" On a new board I like to check that all channels are responding and set to the correct in...
