I got curiouus, and Pat mentioned he's done a couple of Mega-squirt inline
VWs. Went online and did some reading on the MS website (linked below for
the VW app.)
I have a lot more research to do, but a cursory look around at the
information indicates there are plenty of VWs that have been done, the info
is out there, and the conversion to Mega Squirt is downright rea$onable in
cost.
I am going to keep researching some more. The only thing that has me
somewhat intimidated is that I've never been very adept at working with
wiring in complicated compact circuitry and I'm not adept at soldering
stuff.
I think, that with my modified inline VW motor, the ability to refine the
tune, to revise the injection programming to better suit the different cam,
the custom exhaust system and the increased compression ratio, that migtht
make the time and expense (I am sure I will encounter some frustrations)
worth while. I'd expect some further increases in power and fuel efficiency
by replacing the VW factory computer operating parameters with custom tuning
done specifically for this motor as it exists in my vehicle.
Could be interesting..it will certainly be a learning experience..
