Hi xr8eater, the SAFC 11 current model from Nengun is $406. There really is no comparison, the type 1 SAFC only has 5 tuning spots and extrapolates in between them in a crude straight line. The current version has 8 load points for full throttle and another 8 load points for partial throttle, plus it extropolates via an algorithm so it gives a much more accurate A/F ratio adjustment.

The big advantage for me is the separate part throttle correction, previously the tuner had to compromise the A/F ratios. Many cars were too rich at full throttle but just right or a little too lean at part throttle. So you had to choose a middle line when tuning. Plus I can now tune for fuel economy at part throttle and power at full throttle. This makes a difference if you are going to keep your car for some time, you may well save enough fuel to pay for it.

If you do get the earlier SAFC, a tip, mark the spots where the knobs are turned to with white paint dots. They get bumped easily and it is a costly exercise to get the thing retuned.

Hope that helps
