Turning off EGR

[3.8TransAM]

Going thru the hack from gnttype.org, I cant figure out exactly what I need to do to can all egr functions.

The functions run from 2CF thru 373?

I'm used to having something like a temp enable(like for the ccp, directly below it) that I can set high to shut down all egr functions.

Currently set TPS enable/disable very high, but I am still seeing a duty cycle for the egr being commanded.

Want ot shut off period so I can retune my lower maf tables for 128/14.7-8 without interference.

thanks

Been awhile, but looking at an old bin:

2A1: FF (Kills MALF 32?)
2DC-350: 00 (clears EGR Duty cycle Table)
376:FF (Kills CCP?)


This was in a "recall" bin I made for tuning my MAF tables (no egr, open loop). Won't swear that it worked, but I think so.

HTH,
Tom

You might try setting 2CF to FE and 2D0 to FD. That should turn on EGR when TPS >= 99.2% and turn it off when TPS <= 98.8%.

My guess is that I tried FF in both and that didn't work so I resorted to the brute force method of clearing the table.

Why not just pull the damn EGR off and weld it shut no more issues then
What we have always done around here, and many other shops I have worked duing performance mod's if there is no Block off plate for it
