Check radio's ground connection.

Does radio flickering occur when anything is plugged into to ALDL/OBD2 port...? Or only when nothing is plugged in...?

Do you have anything else (i.e. aftermarket) on the CAN bus...?

Usually use 1 WB.

Would use 2 WB's to compare left/right banks.

I have been using 2 WB's, I setup my correction pid to select the leaner WB on the fly.

VATS: yes, should be able to (but I don't remember of there are any 2001/2002 special cases).

VIN: yes (using V7 scantool).

FSV2 does not provide 5V output, you have to provide your own.

FSV2 only provides signal input and signal ground.

Don't drive it like that, but rather mix in some 100 or 120 to bring the octane up.

Are you using V7 or V8 EFILive software?

Glad you got the injectors sorted out.

Also look at the GM.STATExx, pids one of them will indicate the reason for timing pull.

Post your ECM and TCM .ctz files, I'll have a look.

With that overlap you should be able to drop the idle speed.

Sorry I missed your post 2 weeks ago.

In the V8 scantool chart/graph display, right click on the pid, and you will see a display precision.

^ this is a great diagnostic, thanks :cheers:

Steve, Thanks for the update :cheers:

( Hi Madman13, I deleted your duplicate posts, the forum was marking them as unapproved, I'm not sure why. )

Thanks for posting your findings.

Hmmm, interesting!

Also, did you check for leaky injectors...?

Also, did you check for air leaks at the injectors, and between the MAF and intake manifold...?

I'll look at your files.

Are there any airleaks in the exhaust after the NBO2 sensors (say up to 12 inches past)...?

Hi dhoagland,

First, check that you are logging all the pids mentioned in the calc pids and filters that you're using.

Second, you need to use the pid() call to enclose the pid strings (and you...

Post your tune .ctz file, let me take a look around in it.

Do you have the latest V7 software installed...?

Also log TFT, this may give us some insight (if fluid getting too hot then TC is...

Age08, I'll take a look at the file you posted.

Try looking in the Engine Diagnostics segment.

Looks like you've found the tune file location. Thanks for posting it :cheers:

Yes... the info posted by Highlander may be late, but it is a very good method to detect air leaks (you can localize the brake/maf cleaner using the red straw that comes with).
