Simple Digital Systems tuning device

I have an oppurtunity to get one of these for a *decent* price, but I've NEVER heard of anyone in the stang community using one. All i ever hear about it tweecer and PMS. Does anyone have experience with the Simple Digital Systems unit? Can anyone give me insight as to how it would interact with the 5.0 efi system? The guy selling it claims he used it to tune a turbo 5.0.

Can anyone point me in a good resource for the system? Their website leaves little to be desired.

hmm... no one got any input? Maybe I should just go with a tweecer instead.

this SDS unit looks like you get rid of the MAF alltogether and run a MAP setup. its also a complete stand-alone unit that takes the place of the factory unit. Looks a little complicated.





so, as far as the tweecer goes. Is there anyway I can save money on the wideband o2.. meaning, can I just buy the sensor and harness without the display unit in hopes the that it will plug into the tweecer and data log with it??? ugh, i guess I need a quick run-down of how the system works.
