Are you thinking a little more room around the board to get the wire in?
There is a USB header that is designed for a wire in USB, it's through holes so could be wired from either side.

Wait, your trying to use 60-2 trigger setting with a wheel that does not give a pattern for 60-2? I think this may be the route of your random sparking behaviour. I have a feeling this may need a special trigger setting of that high tooth filing into a double -2 gap. Otherwise your trigger is really...

But anyway there are no guarrantees that by the time you send your board to fabrication, these parts are still in stock.

Totally this, things seem to be in and out of stock on a daily basis. Predicting what is going to be available is becoming a gamble.

That's true for the M70 but not the M73.

M70 uses a pair of modified M1.3 motronic units but the M73 uses the much later more complex M5.2 ECU.

The knock sensors will totally have been throwing a fault code if they have cracked. Kind of common on the BMWs of that age as the age/heat cycles get to them after a while. You might want to go for something bigger than the Jag supercharger, iirc they run out of puff around 450hp which will be very...

It is actually easier to spoof the inputs to that generation ECU than it would seem, I have done it on the M3.3 which is the generation before your ECUs. Can you grab the BMW part number from the 2 ECUs you have to confirm what generation they are and I will try to get some details up of how I have ...

You are USA based right?

I think you might get away with taking the CAN messages and transmission info from a 750, 740 or 840. I believe they are very similar and would be surprised to learn of any significant differences in the comms or body modules. Certainly the ready programmed transmission unit is the same part number ...

People have had good results with a few kinds of COPs. Known working setups are: Chevy LS smart coils VW smart coils M50/M52 BMW using audi ignition pack Miata smart coils That is just off the top of my head. The short version is nearly any coils can be made to work but if your in the USA and want l...

That is something a lot of people find. They are intimidated but the apparent complexity of the BMW stuff, once you get into it you realise it's actually pretty simple and standardised across a lot of their cars. They like to evolve things so each generation is not too drastically different to the l...

Some cheap irons are. I have one that turns LEDs on when I solder them with it.

I would say at this stage the best way to play with rusefi is to get a discovery board or one of the compatible nucleo boards and load the RE firmware onto that.

Full TS license is more expensive than a board and then disco/nucleo can be used for development annd testing later.

It is relatively simple to detect poor combustion in one cylinder from the instantaneous speed of the crank shaft. A misfire shows up as a period of declining speed at a time you would be expecting a positive speed delta. I.e. the instantaneous tooth time increases at a point you would expect it to ...

100% agree, it would be easier to dangle the motor back into the bay to get it fired up, we have seen these units be rather touchy about the connections to some of the modules. You would likely do more damage getting everything out to run on the bench than it is worth. Regarding the install of a rus...

I would agree, tuning the M5.2 is a dead end and IMO a purely academic exercise now given modern standalones are catching up with the 90s OEM.

A TLDR on the stock ecu is that the M5.2 is sort of an evolution of the M3.3 used in the E36, on the E36 the program for the ECU is partly in the processors memory but it is also replicated in it's entirety in the ROM, which means it can be read, modified and the processor forced to run totally from...

There is a desire to build a whole ECU stimulator like the Jimstim for rusEFI.

Blundar on here is heading up the task and I am sure he would appreciate the help from an additional skilled coder.

That would be great, longer term we could probably add some of that to the wiki.

Where in the states are you? We have zero interest to handle weird stepper motors and weird pedal - we prefer simpler modern ETBs and simpler modern pedals see https://github.com/rusefi/rusefi/wiki/HOWTO-M73-v12-on-Proteus Your 96 harness is probably not using https://www.ebay.com/itm/333779143374 ...

I don't think that is possible, that would be tunerstudio side and probably not something we could implement.

It may be helpful to you that I am based on the eastern end of the south west of england.

New V2 easy print case is now also good to go.
This fits the V4 and 5 versions of Proteus and is much simpler to print in PETG.

I think within the plan for "smart features" the concept of a panic trigger could be included. A single flag based on a pin state that manually triggers "limp mode" (what ever that may turn out to be or the user chooses it to be). It might actually be worth including that as part...

FSIO would be 100% relevant here, being able to use FSIO for a lot of this would be the quick and dirty way forward until we put them into the code as integrated features. It would also allow the custom bits in the same way as the GPIO. I don't think it would be too bad to ask users to paste in read...

Adding a further suggestion to the pot here, in some cases a custom bit of protection may be wanted, some additional actions that the ECU would need to take over and above the basic intervention. Suggestion is that we expose the flags for each fault condition to the GPIO so it is possible to have th...

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.
