I'm running an Electromotive TEC I in my 20B, but it's not finished yet so I'll get back when it's been tuned and running. I really liked to features of having the stand-alone coils and crank wheel for an accurate, high-voltage spark and timing. The software is pretty easy to work with as well.

Didn't Mariah already tune it?

Sorry Mr. Ace, you're thinking of 3 rotor which is the guy with the white 10th aniv. 20B. He's running the stock ECU which is why he can run the turbos sequentially. Ray from SR Motorsports gave me the initial map and I'm having a local Electromotive dealer do the final tuning.

You're right. I should have looked at your name. :sigh:

power fc reprogrammed by XS. Runs really good but I'm wondering whether I would get more power by going haltech. Can i run less conservative lamda's with a heltech?

The Haltech would allow more flexibility in your setup--injectors, etc.--but you'll lose some of the feautures of the stock ECU, such as electronic control of the oil metering pump. By lambda, do you mean A/F ratio? You'll need the same ratios no matter what ECU you run.
