FAST: what if my boost exceeds the 2 bar MAP sensor?
what happens if I switch to a 3 bar MAP? Will the tables intrapolate with the data I had in the 2 bar GCT file and I just tune for cell above the previous 2 bar limt?- fast4d

FAST: what if my boost exceeds the 2 bar MAP sensor?
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?- fast4d

changing injector size w/FAST
when I changed from 50# to 72# low impedence I had to make some slight changes to the VE. it was making more corrections while in closed loop.- fast4d

VE tables over 100
check your electricals. I had a bad alternator ground. the engine was running crappy and inconsistent. I had high VE numbers just to keep the A/F in check. Once I fixed it I lowered my VE . although it's normal to go over 100 once you get heavy into boost.- fast4d

F.A.S.T. question regarding afterstart idle...
this is happening when the engine is still "cold"? sounds like you need some enrichment - base on coolant temp- fast4d

Fast update...Craig ? Where are we ?
you guys with the "faster" laptops that still has a serial port. use a dos boot disk to boot to dos and run ccom. it's fast because I don't have to wait for windows to boot up. hopefully you have a FAT or FAT32 partition.- fast4d

Inlet Air Temp Sensor.
I have an question regarding this topic currently my air temp sensor is located in the lower intake which samples 1 port. should I relocated the sensor before the throttle body? I suspect the heat of the lower intake (alum) might cause it to read hotter due to heat transfer?- fast4d

Target A/F (Speed Pro)
is your alternator putting out the same voltage as before? how about adequate grounding for the alt and engine? I had my acessories brackets powercoated while I was going turbo from S/C. Since then the car hasn't been running the same. very high VE, inconsistent performance, etc. After some...- fast4d

FAST dashboard question
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,- fast4d

Where do I start tuning??
yes but not right away. I rev it up a little so the "dot" will move out of the cell(s) I just changed. once it comes back then I'll see a change. I could be wrong but the A/F table will still affect even if you are in open loop.- fast4d

Where do I start tuning??
you might want to idle in open loop. Even after switching to a "mild" cam (18" vaccum @ idle) I found it easier to smooth out the idle using open loop. I don't go into close loop till 2k. set idle speed using the screw at the throttle body. only use the IAC follower for fine tuning. once the...- fast4d

FAST VE table not reading boost
I have both the dos and windows verion of c-com. I use the dos version 98% of the time. I only use the windows version to datalog because it's easier. goto bootdisk.com and make a dos boot disk. if your laptop is win95/98/ME then it's using FAT so you can just boot off the dos boot disk...- fast4d

easy FAST C-com question?
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.- fast4d

Autometer A/F gauge hook up to FAST WB?
there are several low cost WB O2 setups with display out there ($300). I bought 1 of them and welded up a second bung so I can view without a laptop.- fast4d
