Re: Proteus - Waterproof, High-feature ECU!

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.

Re: Renault special 60 -2 flywheel on microRusEFI

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.

Re: Looking for a good electrical diagram for M73

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.

Re: JRockland E38 750il gen 1 supercharged

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...

Re: M73 Automatic transmission

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 ...

Re: M73 Automatic transmission

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 ...

Re: rusEfi simulator

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.

Re: Audi v8 with ITBs

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 ...

Re: M73 Automatic transmission

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...

Re: Bmw 850 ci M73 supercharged

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...

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.

Suggestion is that we expose the flags for each fault condition to the GPIO so it is possible to have th...
