hmmm...you can't really unless...
well I had the afc for about a year before moving to an additional injector controller from efi systems. (www.efisystems.com)
My car is an 88 and unless you have the 90 (full range TPS) its gonna be tough to get it to work right.
Yes it works at low end, but not where you need it on top. You could theoretically make it work by adding some HUGE secondaries and tuning the thing very lean. The problem I was having was that the AFM was actually hitting wide open and wouldn't measure anymore. This was on a pretty big turbo (t04 compressor on stock 91 turbo). But in the top of the gears the AFM reading on the bottom line of the AFC face would climb and then peak out at a point. So you can see how this thing can get untunable real quick.
I am just getting back into TII's (wife and baby took my other ones) so I am gonna have to start this stuff all over again. But I am def. going to go with an additional injector controllers again.
