Scanmaster 3 on a 91 Stealth TT

[bluestealth2003]

I purchased a scanmaster 3 because my car has been running strange. Now that I have one installed, I don't know what normal readings are. Can anyone share what their readings are so I can compare? I have a 91 Stealth TT. Below is the data I got:

bst: 25.8
AFR: 10.0
02t: 34
Lt: 81
Mt: 100
Ht: 100
AF: 56
R: 843
InJ: 2.8
Idc: 01
TPS: 08
SP: 16
MPH: 0
CLt: 174
CEL: -
BAt: 13.9
iSc: 04
AtS: 96

the o2 trim looks a little low, and the mid and high trims have not learned yet

how is the car configured? Any modifications?

wow, thats a large pile of parts.

Did you buy the MAF, ARC2, and injectors as a package? The ARC-2 is really Matt Monet's thing, so you will need to get him into the loop. I don't have that much experience with it.

When you say "running strange", what do you mean?

Do you still have the fuel pump resistor and relay?

What fuel rails and fuel pressure regulator?

Is your BOV vented to atmosphere? Are you running the stock Y pipe?

Yes, the MAF, ARC2 and injectors all came as a package but that was several years ago. I've never gotten the car to run properly in that time period mostly because I upgraded too many things at the same time.

I've contacted Matt before about helping me tune the ARC2, but I think I have a deeper issue going on. The car has always ran super rich since the upgrades. Recently I took out the 660cc injectors to install the original ones and I could actually get the car to idle properly (proper A/F ratio). For some reason it can't handle the bigger injectors.

I don't remember doing anything with the fuel pump resistor and relay, but I have read about that. I wasn't sure what the benefit of that was.

I've got the stock fuel rails and fuel pressure regulator.

I've got the Greddy Type S BOV and I believe it is vented to the atmosphere (the angled nipple has nothing connected to it).

I've got all of the intake pipes replaced since I now have a FMIC.
