Megasquirt m52?

[318isbmw]

It's your funeral.

For not running obd1 setup instead?

Or another good standalone.

At the very least, spring for MSII. It almost passes for a workable ECU. Sometimes.

ya, I'm starting with a motor that has no ecu or wiring to begin w/ so I'm figuring I'll run megasquirt for something different to learn as well as I'm not under a time frame and I'm planning on turbo in future.

I am going into "if you can't say anything nice..." mode now. I won't post in this thread again. Good luck.

Also, talk to Donovan (BMWSOB) on BF.c or on the Tech.
He has a turbo'd M52 that runs low 11's that is running on MS2.

Awesome, thanks much.

Its all good matt, I've been readin about both sides so I understand where ur comin from, I respect that, its all good. Thanks for having the self restraint unlike most people to not turn it into a shit fest, I appreciate it.

Matt, I glad you joined the forum you are a good resource.

All very possible with the 413.

All the info on basic tuning of the 413 has been posted on BFC. Literally spelled out for anyone who wants to try it.

yes, it is possible to tune it and it is also a more stable hardware platform. But you cannot tinker with the proprietary software/hardware of motronic (there is no knowledge/docs in the open about that), also one would learn a whole bunch more about EFI by going MS(1/2) and DIY the whole thing. So if you want to spend time to figure out every little detail and learn a bunch in the process, and have a reliable daily always available to save your a$$ in case things don't work, go MS2. Otherwise stick with motronic.
I just made a plug and play harness for my MS2 using a dead motronic, so swapping the plugs (MS2/Motronic) takes 5 seconds.

also M20 run much smaller compression ratio (9:1), so they won't knock easily. M52 has 10.5:1 AFAIK

Are you sure Donovan's actually taken the car to the strip since it's had the M52 in it? Last I knew, the car hadn't actually made it there yet, and he's still trying to get it running right.

Yes, yesterday there was a private track rental at MIR and I saw a video of him run. He managed a 1.67 60' and crossed the line at like 123 or something.

Ya, these are some of the principles I'm working off of. Basically I'm gonna build it with the idea of a turbo in the future. Also, I'm wanting to do it myself cuz i've never done a MS2 setup before. Worked lots tuning hotrods, but that's a whole different way to the same solution for different cars.

Yes I know the m20 has lower compression, but I'm not interested in an m20, I wanna do a swap for the fun of it. Something to stand out from the crowd type of deal. Also build something that I can do myself without having to have others do the work.
The next car my buddy and I are building will be m20 megasquirt powered though...

ok... I'm lost, if I'm runnin megasquirt why do I need a new engine?

[BeirBrennerE30]

megasquirt doesnt offer very good engine control... a lot of people blow engines because they dont really understand what they are doing with megasquirt

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


BINGO!!!!



And how are you going to run the coils? I only see 1 coil driver in megasquirt.
