Yesterday afternoon I had such a “duh” moment. I realized that I can use a Megasquirt system on the Saab engine I was originally planning on using. So now the plan is to get myself a 2004-2011 Saab 9-3 2.0T with the B207R engine. 2003 and 2008-11 all wheel drive models had secondary air injection which is stupid. I can remove it, but it’s just easier to not have it in the first place. Hopefully, I’ll be able to use the car’s original computer to run things, but if that’s not possible I can always go with Megasquirt. This engine would be easier to run with Megasquirt than the LE5 anyways because the B207 doesn’t have variable valve timing.
