Anyone else have experience with the Megasquirt? I just started looking at these. Might have saved a bit of money over the Haltech I bought last year. The Haltech is doing fine, though. If I could just find a few minutes to get the high rpm WOT maps down out of the 9.x AFR numbers. I think I could be a little faster if I was leaner.

That's neat
So what's it have to do with the megasquirt again?
My megasquirt will run my peripheral port engine... I drove it around as a daily driver for about 6 months on a stock port S4 6 port engine with custom manifolds, never had a single problem with it.

Well if your just looking to learn some simple EFI for cheap Megasquirt is a good option, Microtech also makes some cheap boxes.
You do get what you pay for as far as price range though.
There is a reason that a Autronic or Electromotive box costs triple what a Microtech flying lead does, but as I'm sure you know it depends on what your needs and budget are.

MS is now getting to the point where there is a critical mass of users with rotaries to help support people. It's never going to be totally pain free (It's a DIY project), but it gets better with each code iteration.
Now that some people have picked up on the igntion code development it won't be long before there are most of the options that are needed for 90% of people. For the other 10% they will either have to be patient or start learning to code in C :-)
For your application it should not be too hard to get up and running. If you can let myself or Roger have a dyno plot we can probably knock up a WOT map and work out injector sizing for you.

Even the decel fuel cut wasnt helping on the MS, b/c its time based. And on top of that, any tuning that would make the car smoother in that low rpm range would cause a big stumble on WOT shifts.

This sounds like a transient throttle issue more than a decel fuel-cut issue?
Sounds like you need a full 2D transient throttle function - Haltech E11 can do this.

But with the haltech you do not have access to the source code to add you own function. That's the real joy. When a problem is found the code can be changed to meet the challenge. And as there are code monkeys with no spanner skills and spanner monkeys with no code skills (and a few with both skills) the mutual bartering that takes place brings people together and makes friends in a way no Haltech can.
Interestingly a lot of the issues with transients can be cured by using mapdot as well as tpsdot in the calculations. A few people I know have abandoned TPS all together.

2D enrichment is now being tested. Once done on accel, decel is easy to add. Don't you just love open source :-)
