"746 ECU" I changed EGR temps to 0's and now when driving around, I see that the BLM's are showing rich. Something definitely has changed. I can kinda understand that, but when I look at the log I see that the AIR Divert solenoid is still going on and off. Is that correct or does that mean that I haven't disabled the EGR and need to also disconnect the vacuum line to the valve?
Also, should I now correct my VE table to correct the rich BLM's?

 

Will need to also disable the CCP. That will add fuel vapors to the mix. The AIR shoudn't have an affect on your VE table tuning.

Rbob, what's the CCP? Thanks for the help, too.

 

Charcoal Cannister Purge. It is the black plastic coffee-can size can with the soleniod on top. Holds fuel vapours from the tank to be burned off later. Prevents HC emissions while the vehicle is sitting.

So do I unplug the hose going from the canister to the front of the TBI unit? If I unplug the solenoid it could throw a code. I'm not sure if this old of ECU actually monitors the solenoid itself though.

 

No code for unplugged soleniod. Better off disconnecting and plugging the line to the TB. Every couple of days hook it back up to purge the cannister.

I'll give that a try. Since I disabled the EGR, I've been taking a ton of fuel out of the VE table and it still keeps showing rich. I'll try this and keep taking fuel out to see how it goes I guess. I was hoping to help out the gas mileage a little since I can pull some fuel out now.
