[norbs]

You will be giving up the following features with the DFI.

Evap canister control
Lean Cruise based on MPH 14.7 for cruise 15.4 for highway mode with highway spark advance.
adjustable timing advance for 3 gear, different A/f target for 3rd
Fuel cutoff on Decel
A/c idle rpm/ fuel enrichement .4 tenths of a sec before a/c clutch engages
Leaner idle a/f ratios stability from using the MAF and Stock O2 at lower speeds
Maintained a/f Ratio between Park and Gear, and different idle speeds for in and out of gear.
Reduced Data logging power logger logger 19 frames/sec for 44 items at once.
MPH data logging.


This list is pretty hefty I would think...but if its just a Race car you don;t all that stuff

Dont think I'm using these but a lot of those items sound like things that we made adjustments to with the XFI. I'm going to look into that. If some of those features are what makes his car run so good than I'm not gonna run the motor without them.
