If our cars are high impedence, could we use the dsm 450cc with resistors? I know they might seem a bit much, but I plan on using the greddy emanage to adjust the a/f ratio.

P.S.- Its for a T28

 

Already been covered but yes.

 

Please run a search. 450 isn't too large (with proper piggyback or EMS), but low impedence may damage your ECU if you don't account for the difference in resistence. If you read some of the existing threads regarding this issue, you'd learn that a few Miragers have fried ECU's that way. The physical size of the injectors may be different as well, causing a lot of condensation of fuel in the IM. I don't know if anyone has used this technique yet. It's perfectly feasible, however there are a bunch of possible hiccoughs that should be looked out for...the two big ones being what Quez and I mentioned.
