Topgunz full supercharger kits!!

I think this is the best SC kit out there and I'm trying to decide what level of PITA I'll be living with. Pulled the engine and tranny out of my 69 Vette a couple of times. Not that big of a deal. Tranny linkage is what everyone's paranoid on that one but adjusting it is pretty easy. I can build it off line if I've got a spare engine and tranny. If I blow it up I still have the original to put back in. I'm guessing it would be about 12 hrs the first time could bring it down to 5 or 6 after that.

With the a2a you would fail visual of course.

Aside from using a flex fuel sensor, there are other learning approaches that could be implemented using the ecutek custom programming language to determine ethanol content directly from combustion results, thus not requiring the need for a flex fuel sensor. There are multiple ways to handle flex fuel, each approach has its advantages/disadvantages.

I recently did one and I used every single table/variable that was available to implement my custom airflow modeling and fail-safes. Have you tried running an older version of the firmware? In theory, it should work fine if you could find a firmware that wouldn't trigger DTCs.
