well im graduating and moving out probly... so it will probly be a lil bit of time before i can spare $600 for it. PLus i need to have my other truck running so I can afford to have some down time on the T/A (cuz right now it is my daily...).
Lets make a lil situation real quick... lets say i have it all wired and ready to rock. How long beforei oculd have it tuned good enough to drive everyday? Cuz like you and I said, the learning curve is steep. So Im curious how long it owuld take to get going...

I already had a used FAST ECM w/ WBO2 sensor to go with it. You can probably get used for around $900 bringing your total setup to around $1600. It's steep compared to megasquirt, but the time saved was more than worth it.

Re: Tuning for boost with stock pcm?
In more food for thought, a friend of mine mentioned the whole "megasquirt" thing to me a while back - but when i first looked it over I didnt want to get that deep into things so I decided not to do it on my car.
He used the "auto tune" on a rotary engine and to my amazement it worked suprisingly well. I wouldnt have thought it would work so well for a "tune itself" sort of setup - it was quite accurate. I dont know how effective it would be on some of our cars though, as running lean while it figures things out might mean the end of a piston of something.

Considering you've done what I thought to be too insane (and seem to have great results!) what do you feel about the auto tune on our cars? Seem viable? Also, did you ever consider allowing the MS2 to function in a way to provide traction control? Either it could be used with the speed sensors to pull timing, or just "gimmick" it so that if the rpm increases above a certain rate that it pulls timing... Having a reasonable and effective traction control system for $600 on a 600+rwhp car would be a good investment all on its own!

the autotune feature will work very well with a wideband sensor, i am only running a narrowband, stock o2 sensor for right now, so i have only used the autotune for idle and cruising around, and it has proven to work quite well. The problem with the narrowband and autotune is if you are running so rich that you have unburned fuel in the exhaust, the o2 sensor will read that unburned fuel as dead lean, and then autotune will add more fuel, creating an even richer engine. so with a narrowband, the tune has to be somewhat close before you can use the autotune feature. My MSII has been awesome so far and i highly recomend it to anyone, all you need is basic soldering skills and patience...then you can go spend the $2K you saved on a 9 inch rear end
