Are there any tables or constants in the $61 code that could be manipulated to disable or minimize the effects of EGR activation? This has probably been hit before, but I didn't find anything in a search. I also looked at the $61 hac and I honestly couldn't see anything, but I am sure I wasn't looking in the right places. Does anyone have any table or constant addresses that I could play with? I am trying to do a rudimentary fan install without having to go ROMless just yet.
Thanks in advance!

Thanks Grumpy. I found those. I was wondering if there was anything else I could use to try and minimize the impacts of EGR on my fuel and spark so that I can run the fan off the EGR without having to go ROMless for a while. AFAICT, it ain't gonna happen. I wonder if I could use tranny controls in conjunction with something else.

 

Fire up the ole ECM bench, and see what happens.

It's only enevitiable, you going ROMless.
To argue is futile, you will be assimulated.

 

$D019 is added EGR SA

$D2A1 is BPC table for EGR

I too see a ROMLess future for you. . .

Thank you both for your generous visions, Master Jedi. The young Paduwan will learn with time the ways of the Force...
