Fast 30405-kit Has anyone used the fast LS 30405-kit yet?http://www.fuelairspark.com/fas/gm-l...ntrol-kithtml/ ? I can't seem to find any info on this system. Looks like a nice setup and uses stock coils and sensors.
also interested to know. I found a few threads on other websites from a few years ago about a lot of problems with FAST on LS motors but nothing specific to this kit.
I like the price over the holley stuff.

A few months later...I called FAST to find out more. While it does have a wideband sensor, it uses only one upstream O2 sensor mounted on one bank, only.
It does not fire the injectors sequentially/in order. Rather, it fires the injectors all together, one bank at a time.
Also, (I hope I heard this correctly!) the maf sensor is not used. Instead, FAST substitutes their own (MAP?) sensor.
I verified each answer with the tech, because the answers were not what I expected.
It seemed as if the tech was emphasizing that this system was utilitarian...for engine swaps, so that one could get up and running with the least effort.

I have a question for this kit.
I'm looking at using this kit for a ls swap in a C10.
Since it uses the MAP (speed density tuning) can you use a 3bar MAP?
Will it support forced induction?
