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...

Just something to note here, I have found the lower my battery charge the longer the engine takes to fire, with a charged battery I can get OEM quality starting. I am investigating this a little as I am wondering if this is an effect of not having a voltage correction for dwell and a large voltage d...

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)

I have "moved my flywheel"

Actually I modified my front pulley a while ago so I have the 324 degree offset for the later motronic VVT engines.

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.

STL attached. This has not yet been tested with a genuine MRE case, only against the case adapter so may need some small changes to suit. It will need a pretty good printer as the locating tabs on the back part are only 0.2mm smaller than the holes in the front plate and the spacing between the 8 ho...

We had a request for a blanking plug/cable gland to use on an MRE instead of the Molex plug so I had a quick go at it this evening. It was not easy to work out a way to have the geometry of the Molex injection molded plug and still be able to print the part with good quality and printable holes but ...

Some nice pictures and even a pinout here:

3d printing STL is attached.

So after discussions about cases and how we are tied to one specific Chinese case at the moment I took a few hours while I was off work to look into a viable alternative. I did a bit of hunting and found a viable case - Hammond 1455L 1202BK This case is 123mm x 103mm x 30.5mm and is the smallest sto...

Cannot take the credit - It is mck1117 that built the board

However I can confirm that full sequential with COP works for 6 cylinders at least on Frankenso.

One thought, does it need to fit the existing case at all? Just has to fit in the same space.

I have a motronic connector out of the car at the moment. I will take a look how hard it is to replicate an end plate.

Just realised something about this.
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.

Thanks Andrey.
I will try to take a look at the Vauxhall and Volvo stuff too, wondering how similar they are now.

Do we think that we can get away with just one of those plugs?
Do we think they may be compatible or interchange?

At this time the ecu has run exactly one engine and is only at rev 0.3, I have a few rev 0.2 boards arriving soon but won't have any on a car for several weeks. The board is believed to be OK so feel free to take the plunge if you want, however frankenso is more proven and can handle V8 sequential j...

Always used the USB on the discovery board so do not worry too much about the USB direct onto the Frankenso board.

Tests?

What would you be looking for? I can always add something.

It was really intended to be a quick intro presentation.

I can't recall seeing any thing that did not refer to the LEDS by their number (like D15 etc) or their function, i.e. Run, Fatal, Coms etc etc.

I have started using blue for most things as I have a ton of them and the only ones with specific colours are the 4 named ones.

Thank you for spotting those couple of things. I will try to get a chance to update and correct those things. Regarding the resistor it looks like you are correct that it is R407. This would be a ""220" resistor which translates to a 22 ohm. These resistors are configured the same as for all the oth...

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.

Let me dig out the electrical manual I have for the 750i should help with a lot of this. Otherwise for BMW work the bentley manual is the goto. https://www.amazon.co.uk/BMW-E38-Service-Manual-740il/dp/0837616182 Perhaps these links will be of use: http://www.e38.org/? https://www.meeknet.co.uk/E38/P...

Also, a couple of cool gearbox links for you:

The transmission is the same Bosch 88pin plug as the ECU. (good source of cheap 88pin ecu side plugs as they are hard to get). You might be able to get away with using the transmission ECU from a 530/540 or 740 v8, as far as I am aware it is nearly identical but check the ETK. The unit comes up as u...

I can also confirm the VNH2SP30 works quite well as a low cost, easily available option. Had no trouble running throttles from 40-70mm on the bench with it.

Preferred is the OEM style chips but the VNH2SP30 will do the job.

That was my thoughts earlier today while at work, best if we had something that holds the programmer in place.
Although I am left to think that it is a lot of fuss to replace something that already works ok if we are careful.

That is actually impressively stable, to the point of making the Alpha-N a little redundant. MAP windowing is a really good thing for us to have, combined with the other settings that's actually a pretty powerful toolset.

I was going to suggest we get hold of some individual pogo pins and push them into a 3d printed holder. Regarding 3d printing strength if done right I have managed to use it for suspension prototypes that could hold the weight of the car in order to do geometry checks. Things have advanced a lot and...

Sorry to jump in a bit late on this but just noticed the suggestion of an innovate WBO2, personal experience has proven what the online reviews say - The innovate stuff is unreliable junk. After switching to an AEM X-series gauge I wish I had gone with one at the start. The new X series is an awesom...
