oh, yeah I forgot to mention. I'll be using a wide band O2 sensor and the MSII box comes with a 20 PSI max MAP sensor. I thought about going true SFI but I'm getting a new better cylinder head and if I make an oopsie, it's a $300 mistake. I'll get it going with a standard TBI setup then if that runs good and I feel comfterble with it, I'll pull it apart and drill for injectors, I arleady would have the controller, would just need recalibrated. as for the TPS, I'd probably throw a new 1 on the Throttle bodie. The MSII uses a VR signal ( can be got from a Duraspark II distributor or even a MSD box can provide it ) to pulse the injectors, pulse width and all that is changable, for cold start, warm and operating temp. there is a TPS calibration wizard to take care of TPS complications. I knew about needing new injectors. 36 # per hour is what I should be using, I'll run 15 PSI of fuel preassure with a boost refrenced EFI fuel preassure regulator.

The Megasquirt is getting popular, by far the cheapest tunable ECM your going to find, started out as a build it yourself box, giving all the parts and good instructions selling in ' group buys ' but now 2 places sell assembled box's and Megasquirt kits. the place I'm getting the stuff from is www.glensgarage.com the software is free downloadable off the official Megasquirt site
