M42 ECU Conversion: Link G4X / E36X

[bmwman91]

The Link ECU uses the same 88 pin connector, so I could just depin the plug & move stuff around as needed. But, I am planning to add all sorts of features and rewire some stuff, so I want to do all...

You guys get a chance to pull the harnesses / look them over? I shot some PMs out over the weekend. Let me know. Thanks.

[bmwman91]

Thanks, I may end up bugging this guy since the r3v'ers with harnesses have not gotten back to me.

I am going to document my ECU conversion as it progresses over the next few months and share as much info as possible. While the M42-specific stuff won't be useful to all that many people since it's still...

[bmwman91]

Yeah, I do plan to document it in my usual OCD style....

[bmwman91]

OK, yeah it should be the one that I am looking for. If you have a chance to snap a quick picture of the battery tray area where the harness is grounded and connected to the terminals on the firewall...

[bmwman91]

I only need the engine harness, which is an entirely separate harness from everything else you'll need for your swap. It can be removed 100% without any cutting or damaging anything else. C101 is the...

[bmwman91]

Yeah, I gotta stop by the local dyno shop and get a couple of runs in. The car is running smooth and strong now (so of course I need to start a new project that will render it inoperable and not running...

[bmwman91]

Big plans. I have a stand alone ECU on order, and I am going to be modifying a stock harness to support full sequential injection, knock control, traction control (will take some experimenting with the...

[bmwman91]

Well, I just pulled the trigger on the Link E36X ECU. God help me, I am once again violating the ancient wisdom of "it if ain't broke don't fix it" but so it goes with the E30. It turns out...

[bmwman91]

I'd like to buy an E30 M42 engine wire harness. No worries if it is dirty/greasy, but it must have no cut wires or other damage to the conductors or connectors. PM me if you have one.

Th...

I had looked into converting to M1.7.3 since that would get me knock sensing and some improved idle control, but it started looking like more work than going stand-alone with less tunability and expandability....

[bmwman91]

It has been a couple thousand miles now, and I wanted to pop back in here with an update. Well, less an update than just a note. I am absolutely loving this engine and the car is more fun than ever. Whatever...

[bmwman91]

Yeah, it was fun being <200 in rank while it lasted. I am glad that we are getting clobbered though since it means that global contribution has gone through the roof.

And yeah, it is insane...

[bmwman91]

Very cool! Although I already built a system (ripped out all the factory wiring), this would be a great time saver for a lot of people. Just crimp some 12" twisted-pair wires onto the signal pins...

[bmwman91]

How big was the disparity in voter turnout percentages between rural and urban areas? Four years ago, a big reason for Clinton's loss was that lots of "urban liberals" did could not be bothered...

[bmwman91]

I have yet to see credible evidence that there is any more voting fraud/incompetence than usual. A bunch of people predicted the swing in votes for Trump and then Biden before the election. More Trump...

[bmwman91]

You can try using a piece of fine emery cloth or maybe 800 grit sand paper to knock-down any raised material around the groove. Also, installing the seal 1mm in/outset from the old one is not a bad idea...

[bmwman91]

The arrow on the flywheel aligns with one and only one tooth on the trigger wheel. If you look closely, there is one tooth with a little notch in it, and that is the one.

Similarly, the cams...

I have noticed that my transmission makes a fairly loud rattling/hissing noise under medium to high throttle in gears 2 and 4. The noise is fairly apparent in the cabin. For a long time I thought it was...
