Is there a site for scanmaster??

[y26]

Just wondering if there is a primary site for scanmaster that will explain all the readings and other facts...

Thanks

go to www.gnttype.org and look at the basic operating perameters page. It will show you where all the readings should be.

Is it best to see Blm and Intergrator at idle????? or WOT


I got the car at 47 psi static fuel, 17psi boost, 93 octane.
02 volts 752 kR 1.2

but blm is 144 at idle
int 150 idle

SHould i check them at WOT?????

Sumthin' sounds wrong.

47 psi sounds high, but blm at 144 and int @150 sounds like you aren't getting enough fuel. As does your 02 at 752.

BLMs and INT at idle should be around 128 +/- 10 for a perfect tune. O2s at WOT should be between 770-800. BLMs and INTs are somewhat complicated, and your best bet is to read the gnttype write-up on them.

47psi may be too high and it is making your fuel pump work too hard and not letting enough fuel in. Usuall is 43-45 psi. Do you have a fresh fuel pump that is hot wired?

I see you do have a fuel pump. Is your chip set up for those injectors? 17 lbs of boost may be just a touch high. You are running it on the edge. That is about where I would run it, but I tune until I see knock and then back it down a touch since I am running 25 psi. 1.2 degrees of knock at 17 psi isn't bad. 752 02 count at WOT is about as lean as you want to see. If it gets any lower, you may want to drop the boost about 1/2 lb.

As I said, your wot #s are pretty good. Your idle and blm seem off. Is your TPS (throttle position sensor) and IAC (idle air control) sensor in spec?

TPS should be .44 and 4.5+(when gas is floored).

Yes I had Jay carter burn a chip for my injectors. Someone mentioned that he may need to tweak it out. I thought that was alot of fuel especially with 40lbs injectors. Now when i lower the fuel the o2 count goes lower. Should i tune the blm at idle??? Tps is at .42 4.66 WOT.


Thanks

Got some new readings as of now, Int is at 128 but BL is 140, i made no adjustments as of last post......

Iac 23
Tps .42

That sounds a lot better. Watch the blms, they should move around a little. Like I said, go to the www.gnttype.org and read about blms and ints. Its pretty overwhelming, but you just need to get the concept.
