FIAV Bypass for 1990 Throttlebody??

[tsi1991awd]

My old DSM was a 91, and the FIAV Bypass plate bolted up fine. But now I have a 1990 and the throttle body is different. Will the Bypass Plate for the 91 work on the 90? Or is there a different plate that needs to be used or what?

On a 90 throttle body there are no bolts connecting the FIAV to the throttle body. If you want to get rid of it you have to cut it off and weld the passages shut. You can make a plate as well and have it welded on.

If I left the FIAV and ISC on the TB, could I get rid of the coolant lines and just use DSMLink to override those, or do I have to remove them in order for DSMLink to compensate?
