found this while cruising around various turbo sites on the internet. I contacted the Tim Systems Co address, this is the overview manual that was sent.

interesting approach to correcting the lean condition as boost increases

I saw this some years ago. Might as well use Megasquirt for boost enrichment. I'll ask you the same question I asked Tim. Where is the engine speed (RPM) input to the magic box? Doesn't matter anyway. They aren't being made any longer.

By the time you get done adding "magic boxes" to fix problems with an analog fuel system, you might as well take the plunge an invest the money in a digital fuel injection system.

I know Mega Squirt gets a lot of play here, and it is likely justified,,just looking around for an alternative.

I did enjoy the following quote from the MS site:
VERY IMPORTANT! If you do not own at least two fire extinguishers, go buy some right now! Experimentation with EFI can be very dangerous because you are playing with high pressure gasoline. Install at least one fire extinguisher in your work area (away from where the fire is mostly likely to occur) and carry another one in your car. Do not ignore this advice. We do not want to be visiting you in the hospital or worse!
