Adger, you got me thinking more about this. I'm going tonpull that thing and measure that with a dial indicator, with my dvom connected. Thinking about my lab 'scope connected to see what kind of wave form I get with both the old and new switch to see if the new one is ant cleaner. It was too cold and wet to test today so we got some running around done. Think I can get in on a track rental Mon, so will do some investigation about this tomorrow (Sun).
Thanks for some new thinking about this.
Ed

I always had stick cars before. They are way more fun to drive, no doubt about it.
I'm not up to more maintenance than I have now.

Now, GET OFF MY BUTT ABOUT BUILDING A STICK CAR!!
LMAO!

Ed, does your XFI have an internal datalogger? If so can you view parameters such as rev limit signal voltage? My system indicates a certain voltage ....3.2 volts = rev limiter on 0 volts = rev limit off. May be a way of seeing if in fact it's being requested to be on. Also may have to set sample rate very high.... fast as comm will allow. Just a thought. Joe

Joe, it does. I have never noticed that parameter. Sure something to look at!
Thanks Joe!!

Ed, Are you seeing any abrupt changes in your injector Pulse width or timing? If you can see it on the Datalogger lookat the Pulse width closely it should not change, if it does we;d need to see if it's due to some incorrect input. Wish I were more familiar with the FAST system, however diagnosis should follow the same approach. Please let me know if you see anything irregular as far as the PW or timing. Joe Forgot to ask what inputs are you using for Crk and Cam? Possible Crk sensor issue, as I believe Cam is only used at start up
