Joel,
    If you don't get any more pertinent responses, you  might try using a 
wide band O2 sensor in the exhaust downstream of the turbo to  give feedback to 
your Megasquirt controller.  Initially try setting the  controller to run 
stoichiometric (around 14.6 A/F ratio) under all  conditions.  Then you probably 
have to richen up the mix (say 12 to 13 A/F)  for smooth idling and high load 
operation as well as sudden throttle  opening.  But keep the stoich. setting for 
economical cruising.  If  you have good air/fuel distribution and good 
ignition settings, you might even  be able to run low load cruising at leaner than 
stoichiometric, but you'll  probably need a knock sensor to handle that (Ray 
Sedman's SafeGuard would be  ideal for that).  Also, lean operation will tend to 
increase the NOx  production so you might be in VIOLATION of the current 
emission  regulations.  But I'll never tell<GGGGG>
    Please let us know how it works out.

My  buddy Shawn is just about ready to fire up his .60over, Isky Cam'd 140
now  with individual TBs inplace of the carbs. We were thinking we might
have an  easier time if we had some fuel maps from other 'squirted 'vairs to
work  from. Anybody able to  help?
