W/A injection and NLTS

Skinnaird · 12-30-2006

I have a base kit installed on a '90 Eagle Talon. (Works GREAT, BTW!).

My custom ECU has a "No Lift To shift" feature that cuts fuel when the clutch is pushed in. Essentially, when using this, the fuel injectors will be closed, but the water/meth injection will still be on. (I run a 50/50 mix with an M5 nozzle).

Is it possible this will cause the meth to burn too leanly?

We have not heard of any issues with this. In fact it's better you have some fuel in there under boost instead on nothing that's how you run lean and pop a piston. Methanol run richer than pump gas by the way.

I was getting a bad miss/stumble after using the NLTS feature, but I've since cleared it up.

My theory: I use a switch at the TOP of the clutch throw to start the NLTS (ie: shut off the injectors). Most people use a switch at the bottom of the throw. I'm guessing that the W/A injection may have been wetting the plugs enough to cause them to missfire until they cleared up.

My fix: I've connected the boost switch ground to the clutch switch. This shuts BOTH the injectors and the W/A injection off during the NLTS.

The miss/stumble is now gone.
