I would do a Holly Dominator EFI . When I say it can do anything you want I mean it ! It logs everything that a racepak can , and can use all the information from any sensor to adjust anything you want . There are three axis tables to configure any information and two axis tables for changing conditions on the fly . Adjustments are limitless .

If you want to have the car take out timing with front end ride height , make a table . Rear wheel tire temperature vs track temperature , Front tire vs rear tire speed diferance in percent / slip angle . Temperature of the cylinder head can make the lights turn on and have the left signal light blink !just make a table for it in the program ,,super easy .

Anything
