SVO extender and Methanol?

[micheal985]

Will the Extender correct the Air fuel ratio when using methanol injection?

I do not think it is going to automatically change when meth is being used. Meaning, If you’re a/f ratio is set to 11.0 now, and the meth is added, it is still going to fatten it up the extra .5 to 1.0 that it usually does. However you should be able to use the extender to lean it back out again, but use of a wide band will be needed to make sure of the changes it is making. Going .5 leaner with the extender settings does not always equal the A/F ratio actually changing .5.

Ok that make sense. My PMs went out on me at a ford vs chevy race. I put the extender in, hooked the vacuum line to the BTM and the car ran the best MPH without methanol 131. My sixty foot fell off from 1.4 to 1.5 but the car et 10.30- 10.40. best et with the PMS was 10.20-10.30. this tells me I need to work on my tune in the PMS. Turning on the methanol with the added timing my car picks up .3 et and 3-4 MPH.
thanks!
