Re: Rusefi driving of ecu relay

I have a question about how MRE drives the ecu relay. I need to drive this relay on my car because it powers not only the ecu but other main functions. I don't want to change that because I have to swap often between oem ecu and MRE. Does MRE drive this relay? What's the logic of this drive? If not...

That's the exact setup I run on my racecar, down to the coils. Four LS coils, each with its own wire to the ECU, but running wasted.

As someone wholly unfamiliar with Mercedes transmissions, is there anything the transmission computer expects from the ECU to be able to operate?

I agree - that's a good bet. 60-2 is very well supported. If you're already going to have the engine out, seems like an easy option to put in place.

Thank you for the solution.

I will test it when back from work.
I went ahead and changed the firmware so it won't apply any corrections in "fixed" mode. If you update, it should now use exactly the value in the "fixed timing" box when set to fixed mode.

Re: Hello from Canada

no unfortunately, I wish it was normal. The flywheel also has a dowel pin in it (some versions have two), and its own vr sensor next to bellhousing. So yes, 2 sensors just for the crank. One reads starter ring teeth, and because they're all evenly spaced, there's a second sensor triggered by the pi...

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

No this problem is solved, you were perfectly right with you understanding of the problem. But, in the video that shows everything is OK, you can see at the end that the timing display is wrong (-3,6degrees of timing with a fixed 0 timing set up). That is the remaining issue, because I don't know h...

I agree the board functions very well for the tests I made.
But if you cannot rely on the zeroing of the ignition (it is off almost 4 degrees) it is dangerous for whom want to re use a known tune.
With the trigger offset set to 90 or -90, does the ignition timing move with engine speed at all?

Either way should be fine - both the VAG one and Mercedes are Bosch, so the control is identical. Like I said previously, get it running on the existing hardware first - change one thing at a time :D

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

I'm not 100% sure there's an issue - all missing tooth wheels can be a little weird near the missing tooth, which is why no manufacturer puts the missing tooth anywhere near anything importnat. If the ECU syncs ok, and ignition timing/dwell look correct away from the missing tooth, everything seems ...

Tomorrow I'll gather all the specs, part numbers and data that I can from the m111 engine.

Re: Making my 190e More Fun (M111 SC Swap)

What kind of crankshaft trigger wheel do you have? Is it a 60/2 or something weird? Do not know if it's a VR or Hall. If you say it's a two wire sensor those are often VR. Im pretty sure its VR, but I am considering adding a new sensor on the crank pulley. it currently uses a ring on the flex plate...

Not sure why your table and axis dont have values in it..
As discussed a few times now, this is what happens when you update firmware with an incompatible change to the config layout. There was nothing there before, so it just reads out whatever garbage used to be there.

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

The difference in advance from what's programmed is probably from the CLT/IAT advance adjustment tables. Zero those out and you'll get exactly the requested timing.

Re: Dwell problem during starting ?

Oh, looking at your photo in the other thread, it looks like your wheel has a long tooth, not missing teeth. That produces a slightly different timing for the first tooth (especially at low speed, as you've observed). I think that should be okay as far as maintaining trigger sync is concerned, but m...

Re: Dwell problem during starting ?

Your trigger pattern looks a little funky, but it's hard to tell if its an artifact of your scope (since the sample rate looks pretty low) or an artifact of the setup. It looks like the first tooth after the gap comes early, which can happen if the VR sensor isn't spaced correctly off of the wheel. ...
