[Diy_efi] EEC-V Tuning

[Ben P]

yeah. I did hear something about the standard computer being unable to cope 
with more than about 12psi, no matter how modified. Is that true, or is that 
just a MAP sensor limitation?

and how do you go about changing the calibration of the map sensor on a 
factory computer when you change it (to one that reads higher)?

thanks
Ben
