I've just installed my MegasquirtPNP2 and though I haven't scratched ANY surfaces the difference is incredible.

I can't believe the how much smoother the engine is in terms of response. The ease of installation and getting it "working" was so simple. Obviously the name implies it's going t be PNP, but still I suspected I would pull more hair out.

I've started reading the manual, and will probably have to read it a few times to start using this new tool effectively. I've installed/setup a variable TPS, loaded a stock 1.6 tune, and run it at idle/a bit above to snag a log - that's it really.

Now I can scratch "have a computer plugged into my car" off my car nerd bucket list.

WARNING!!! DANGER TO THE MANIFOLD ;)

Good to hear!

I'm still in the process of dealing with wiring, but I didn't go PnP...

Nice! I go back and forth with my MS'd cars. One of them runs great, minimal tuning issues, and is all the awesome. The other I've been fiddling with for years now and while it's good enough to dd, it has some nagging hot start and other issues that I've been unable to resolve. Balancing MAT retard, MAT fuel correction, PID idle control, and ASE/warmup enrichment under almost-operating-temp conditions has proven to be an equation that I can't quite balance so far.

Gearhead, is your E30 the one that runs great or the "other?" I've seen your car on the "featured reader's ride" tab. I've got a M42 powered 318is, and am looking into turbo; I wonder if most people go megasquirt for that sort of thing.

I would say that most people that go to MS are annoyed by something they can't do with the factory computer. Sometimes turbo is easier to deal with than a wild NA setup.

Here's to hoping the miata 1.6 stock map is a good map to start tuning from?

Seems like it would be well developed. I suppose it doesn't hurt that this is just a track car and I live in southern California (therefore I'm much less concerned

The "other" is the one that runs great - custom fuel injection and distributorless ignition on a relatively powerful small block chevy. Took very little to get it to the point of being comfortable in everyday driving; all that's really left is optimizing timing and fueling a little more to improve fuel economy.

I didn't realize my car had ever made it to that tab! In fact, I had completely forgotten that it was even in the Reader's Rides section! I really need to go back and update it; the car has changed a lot since then. The car runs very well most of the time (and has for the last ~35000 miles that it's been turbocharged) but there are a few specific conditions that are harder to replicate that I have not been able to resolve.

I would say that most people running MS are running setups that can't be easily accommodated by a reprogrammed factory ECM. That, or they're updating older systems that don't offer the features that MS does.
