SDS, Simple Digital... Options

[TimT]

We (Bill) just tuned a car the dyno managed by SDS..

Well a result is that we are now SDS distributors..

Its very easy- the reason you can't see that is because you have not used it.

A good example was being able to tune my 912E on a 105 mile trip, from scratch, in the dark through some patches of rain! Because it does not have a PC to hold onto one doesn't need computer skills to use it. You also don't have to gi by a laptop just for the purpose.

I have experience with autronic, haltech, emerald, weber redline and some limited megasquirt experience and have tested all of those against SDS on the same engine, except megasquirt..

The reason the controller is easy to use is it functions with and is complimented by the enrichment knob. When cruising at a given, problematic MP or RPM FUEl value the knob can be richened or leaned to the point where the engine drives best. Then the tuner can click one button to see how much of a percentage of change was needed to take that value to an optimum point. Then with the click of the button again the fuel value can be changed by that percentage and the ECU then sets that as the default.

So if at 11.2MP you are stumbling and hesitant reach over and tweak the knob till the engine smoothes out or you reach the desired AFR you want. Then look at the percentage of knob and add or subtract that amount from the fuel value at 11.2MP- its that simple.

Its so easy that we I fully tune engines on the dyno by my self, even new combos that we have no previous data on. I don't build the same engine over and over- in fact I don't build exactly the same engine twice! I ave never had an issue with tuning a new combo with SDS.

I haven't had the programmer or knob out of the glovebox in my 912E since the week after I installed the system. when Len and I travelled to the runoffs last year we went up through west Virginia and at 5K+ feet the system ran flawlessly.

I'm using SDS with my wife's 79 vert with the Super 2 liter+ Turbo engine. This will be her 100% daily driver 40 miles each way per day. If a girl thats an accountant can tune the system, that proves the point pretty well..
as for performance, Autronic made 3% more peak power than SDS When optimized but the ECU costs double that of SDS and they have shitty support.
Don't condemn something that you haven't tried-
