Re: Unable to do MicroRusEFI first flash on new pre-assembled board

Weird.
I have had issues with solder bridges under some of the smaller chips stopping the USB working but that was a hand assemble and does not explain why it worked before.

is it possible something between the usb and stm has failed? Either a trace or a component?

Re: Unable to do MicroRusEFI first flash on new pre-assembled board

Always a possibility it is cable length, anything above 2m has seemed to potentially cause issues.

Any news on this one?

Re: Proteus - Waterproof, High-feature ECU!

One thing to watch out for, we have just discovered shipping into Norway from the rest of the EU means you get stung with 25% vat, so be aware of that.

If this first batch goes OK and we get a good case solution together this is probably something I will keep in stock in the UK.

Re: 1991 Miata NA6

I am pretty sure those coils are not smart and you would need an IGBT pack for them.

BMW coils have been 3 pin dumb coils for a long time now, they use the 3rd pin for the ground of the secondary coil via a shunt resistor to do ignition monitoring.

Welcome to the forum!

Are you planning MAP or MAF sensor?

As discussed, the transfer function for the M73 MAF sensors is at the link below:

You need this sensor, it is on the second tab.

Posting a list of sensors we have tried and ones that we have known curves available for. I personally have tested the BMW M50 Bosch sensor and Russian has tried a Bosch VAZ sensor. This leads us to believe that most common Bosch sensors will work electrically with just the 5v signal sent to an anal...

Re: BMW V-12 1995 M-73

Hi Bill. Unless the engine has been abused then you will probably find that mechanically it is pretty solid. They are very tough engines and the rings/bores are long lived. Rod bearings are normally the first things to show wear, they are cheap and easy to change but you will need rod bolts, rod bol...

Re: Dwell problem during starting ? No - caution at flywheel setup

I would think strictly that the fixed timing setting should override everything and set the final output value to the desired fixed value.

If that is not the case then I wonder if that needs to be raised as a github issue.

Also, FYI the M5x variable sensor has exactly the same plug on it as the 3 wire idle/WOT TPS so you can reuse the existing loom with the wires put to the correct pins on the RE. (rusEFI)

Re: discrete TPS

The BMW M20 and M30 have this kind of TPS. The general way to deal with that is for them to use an M50-> onward TPS which is variable. There is no reason RE cannot work with a on/off TPS if a MAP sensor is fitted, it just limits you to fueling and spark methods that do not use the TPS like the X-Tau...

Here is my current M20 tune for you to use as a base map for you next test.

Warm up fuelling is a bit heavy at the moment so you may want to dial that down and the crank offset will mean nothing to you for the v12.

Those brass standoffs are for the LCD screen and the yellow plug screws to the board, screws are about the same size as PC case ones but don't use serrated ones, they will damage the board.

Re: 1998 BMW V12 engine M73

For the Bentley E38 manual.

I tried to find a 750 ETM that covered the M73 but the only one I could find was a E32 (M70) or 850 one which does have the M73 and should be very similar but use with caution.
