I'm using a 2 bar MAP sensor with FAST. what if I get 17psi in the manifold? will FAST just use the a/f and timing data closest to the cell within range?

I have "GRS CORR" in my dash while in the VE table. it's not showing any corrections while I'm in close loop. Do I have the right field? which field will show the total correction made by the computer while in close loop? TIA,

which key do I hit if I want to automatically adjust a cell in VE so that correction becomes zero (or close to it) while running in close loop? Thanks.

It would be awesome if you guys would suggest what I should try next. I switched from S/C to turbo and also installed a mild turbo friendly cam from cam motion. I get 18" of vaccum @ 1100rpm Now I'm trying to set idle. I can get it to idle steady and smooth at 1150-1200 rpm. This is...

I'm currently using open loop until about 2500rpm due to a fairly "big" cam. 10" vaccum @ idle I'll soon switch to a turbo setup with a very mild cam (overlap wise). I was told it'll idle like a stock 5.0. 15"+ @ idle. Should I even try to idle in closed loop or should I even bother...

I need to goto an aftermarket engine management on my bmw. It has a coil for each cylinder (6). I'd like to use FAST since I'm familiar with it. Can it control 6 coils? I believe the factory system use a crank position sensor.

I'm using 100 unleaded. I would like to mix in a little leaded 113 octane gas before going to the dyno or track. Will this harm the WB O2 sensor? Since closed loop is dependent on it I'm a little worried.

I've decided to switch from 50 (high impedence) to 72#(low impedence). I know the injector drivers don't need any changes. When I enter the new injector size into the ECU, will it automatically recalculate the VE table for me?

After a long drive then turning off the engine for 5 min it often refuse to start. I pulled a plug and it's NOT soaked/flooded. Usually I can get it started after cranking it a while and give it 50% throttle. What the general strategy in the cranking vs CTS table ,etc.?

is it normal to have VE values of over 100 in cells over 130kPa and around 2200rpm? I'm getting some lean pops from the intake when I accelerate from a stop. anyone got a VE base fuel table I can look at? what does a typical one look like?

I've read and heard negative comments on the MSD 50lb (high impedance). Mainly that they take too long to fire and inconsistances. They are made by rochester. Like to heard some opinions. I can swap them for a set of 83 siemens which are a bit overkill but I'm approaching saturation with the...

I just installed a FAST system in my '89 mustang. I'm not getting a ground from the "fuel pump" wire when the ignition is on. I had to ground my pump relay manually to get it going. I got my engine started for the first time today. The fuel pump field in the dash shows a "0" which means "off" I...
