Fuel and Turbo quest?
Hi...
How do you control fuel when adding a turbo an a TPI engine?
With a SC you use a FMU but with a turbo??
Can I use my DFI setup?
Thanks/N.

Your DFI allows the use of a 2 or 3-BAR MAP sensor, so you can use it for a turbo/supercharged application and control the fuel enrichment there. I would recommend against an FMU, it's just a "Band-aid", and not he proper way to control fuel. Controlling fuel enrichment and timing retard through the ECM is the optimum way and will yield better, more reliable results.
