Which 850 turbo ECU came without EGR and SAS?

I have a '94 850 turbo, and recently acquired a NA intake and throttle body along with the proper 960 throttle plate. I'd like to give it a go without tapping the manifold for EGR. I've heard that there are some '96 cars that had neither SAS or EGR and would like to pick up the proper ECU so that I don't have to worry about my EGR anymore. I just want to make sure if I buy a '96 ECU, that I don't end up getting one meant for a SAS car, or one with EGR. Is there a particular part number to look for? I called Volvo and they said they didn't have any different configurations listed for a '96. Hoping someone here can point me in the right direction.

That's a tough one. My son's '94 850 (non-turbo) had an EGR...I thought only naturally aspirated cars came that way.

Can the NA 850's without SAS and EGR be reflashed with a turbo 850 bin that has been modified to no longer detect/use the SAS and EGR? Will it be compatible with all years of 850's?

You can do an SAS delete easily- just soldering in a cheap resistor between 2 pins on your ECU as I did on my '98 S70 (and I yanked the secondary blower out from under the battery), but I'm sorry but don't know a thing about an EGR delete. Did a google search and found this regarding the EGR. http://volvoforums.com/forum/volvo-850- ... yes-31523/ You might search and find more.

I use Volvo 850 T5-R 240HP 0261204134-355830 with no EGR and no SAS. It also works with an automatic transmission and does not give a CEL for manual swapped car.
