Nice! Knee deep in development now. Have basic boost control up and running. Working on fuel control and logging next week. Then hopefully can get some preliminary tuned 1/4 mile numbers.

Nice! On the alpha testing front we've sent a few alpha systems out.

On the development front, for the Mazda3 at least, I've determined we'll need MAF control to get the gains we're going for. So I have that on our test car now in testing. And will expand to the BETA testers once we're 100% it's working properly.

I don't know yet if MAF control will be required for CX models. If so its likely a different control scheme than the Mazda3 which uses a new SENT based sensor. Hope to find out when we see some alpha tester logs.

Greetings Terry,
I was wondering if it would be possible to fit a stock BMW B58 heat exchanger on the Mazda3 Turbo setup? Or are you guys planning any upgrade for that?

Cheers!
