Thanks for all the input. I PM'd Reverent a few questions and am just waiting for his reply. I'll relay whatever he says if I think it'll contribute to this thread (since others seem to be in a similar boat as me).

In the meanwhile, can anyone give me a reason NOT to just DIY my own MS3/MS3X combo? Is it a bad idea for a somewhat-noob? I get that A/C functionality won't be as good as stock, but as long as it's usable, that's what really matters to me. Any other points to be made here?

 

This depends on your soldering skill and experience with electronics. If you have none then I recommend getting an assembled megasquirt.

If you are confident with soldering then follow a ms3 build writeup such as Frank's/Brain's here: http://westfieldmx5.devocht.com/mega...ms3/90-97-ms3/

Thanks for the link. Looks like there's a DIYPNP ECU connector much cheaper than the DIYBOB. Added it to the first post.

I have a pretty basic knowledge of electronics and am comfortable soldering. What I'm afraid of, if I decide to go DIY, is:

1. Not having vendor support if something goes wrong or I have a question.
2. Finding out there's a feature I need/want that is either impossible to add or cost prohibitive.

 

1. DIYAutotune has awesome support. Here and through email directly to them.
2. I cant help you with that so keep researching on what you need/want and compare.

Why not microsquirt?

 

I'm ready to do the same, I need to do something. I've talked to rev a little. Bus been sporadic. I'm watching this thread for sure. I'm sure some of my questions will be answered as well... wish there was more local support, brain is fairly local but haven't met he or anyone else if for anything but to discuss and get opinions.... can't wait for warmer sunny weather..
