Nice work.


I mounted mine in the same place as proffighter did, see post #10 here:

Another EFI conversion

I cut off the height of the knock sensor from the front leg of the throttle linkage plate and sandwiched the sensor in there. It works great, using a sensitivity of about 26 on the SDS, I can not iduce any know when free revving but have to isolate knock sensing to about 5500 rpm as there is a lot of noise up there and it can sometimes shows up. Also knocks when you run into the rev limit but thats expected with the sudden hard cut the SDS has.
