NEED HELP WITH SCANMASTER READINGS

[griffgoody]

Ive finally pulled my car out of storage (86 GN). Put about 100 miles on the car in the past 5 years. I have a few mods that was done in 2003 or 05. I'm thinking my readings are to low or high on some.

SCANMASTER READINGS AFTER 5 MIN OF RUNNING:

AF---05
LB---39
BAH 13.9
INT 125
BL 105
ATS 73
RPMS 800
TPS .24
IAC 47
NAL 45
If these #'s are to low or to high. Plz let me know how to correct. Tks John

From what I see an been told about mine is that BL should be around 128 now your lean an tps needs to be @ .44 an iac needs to be low 20's hope this helps out.also get it good an warmed up on next scanmaster #'s clt temp around 170 k.

Ok thks. Also, what is BL and IAC. I think TPS is throttle position sensor. If so, how do I get it to be .44

You also have a malfunction code of 45. Dont remember what that is and i dont have my list with me, but those are listed in the scanmaster user manual. If you dont have that you can download one from turbotweak.com.

oxygen sensor rich

Thanks rafs-t-type. Causes for this code include bad o2 sensor or wires, wrong chip, or fuel pressure too high. And the manual can be downloaded from fullthrottletech.com. Just google it and youll find it.

Hope this helps.

So, does this mean I need to change 02 sensors.

It could be that...or it could be fuel pressure is too high (I would check that first), or the chip is wrong, or the tune is off.

Any idea how old the current O2 sensor is? They don't last forever & they are usually easy to change.

The last time I changed them was about 8 yrs ago.

Probably wouldn't hurt changing for a new one.

But he switched to vacuum tha next day. He also stated that once you rcv unit to check it to make sure everythings ok. $280 shipped. What do yall think. How and why could this unit blew a fuse.

You should probably make a new post on this subject in the Brakes & Suspension section. More people are apt to see your question that way.

Good luck
