Re: acceleration stumble

An update on the accel stumble, and the results are less than good.  
I still have the problem of the engine leaning out during acceleration. 
 When starting from a standing stop, the engine leans out and has 
no power and tries to shake everything apart from bucking so hard.  
It does this for about 3-7 seconds then clears up, but only when the 
engine goes back into closed loop.  The strange thing is that the 
engine does not do this when in openloop.  I am using the SyTy 
code as a backup for now, but it only runs with the 2 bar setting on 
and running a 1 bar map.  Has anyone converted this code to a NA 
engine?  If so, let me know what you did.
