EGR Disable E6 Definition File

I could use some help disabling the EGR on my 93 GMC, which is the E6 Definition File. I have a couple screen shots from my Tuner Cats Software, Switch and Constants Tables.

Thanks,
dave w

I do not have tunercat; I use Tuner pro. just set your (Disable EGR if MAT < X) to some high number

edit: in your constant table, set every number that has to do with (EGR on) to a very high number

I thought if you used tables/functions and set EGR duty cycle vs. LV8 and RPM to 0 so it doesn't expect the egr to do anything. I don't really know though.

Re: EGR Disable E6 Definition File

I think changing the following ECM switch and constant settings will work?

I haven't seen that flag and I'm playing around w/ a $6E. hmm... looks like it'll work though.

The ECM I'm working with is 16168625 definition file E6, that uses a 27C512 chip. I think the 6E definition file is for ECM 1227165 that uses a 27C128 chip.

right, i think the definition file I'm playing with is for a 350 tpi camaro. I'm just hoping to find some similarities so I can learn by watching what others do.
