okay so about a month ago I ordered the sf3 tuner and 3.73 combo. I ordered my original tunes for 3.73 gears since I had intentions of installing the gears before ever using the tuner. Well that changed so I ordered a new set of tunes from BAMA for 2.73 gears (otherwise exactly the same as what shipped with it)

Now I was not aware that you could set up certain options before flashing the ECU but I seem to be having some difficulty gettin the speedo to read right.

First off If i choose 2.73 axle ratio in the options before flashing my speedo is way off. (speedo showing 70mph when gps indicates less than 60)

If I choose stock from the axle drop down menu for either of the new tunes i got (for the 2.73 gears) the speedo will be correct.

But if I choose stock for the race tune(orignal 3.73 tune) the speedo reads slower. (speedo shows 60 when im actually doing 70) If i choose 2.73 axle ration in the options I get the same problem as above(speedo70 gps60).

Whats going on here? It seems i dont understand what the tuner is using for stock value? (is it what i orignally ordered the tune for or is it looking up whatever was on the stock tune?)

I'm almost positive my car should Have 2.73s in it. I bought it brand new and its a 2012 v6 401a (pony package no brembos)

As it stands the only way to get my speedo reading correctly is to choose "stock" from the pre flash options menu ONLY on the revised 2.73 tunes you guys sent me any other option puts my speedo off.

 

That is pretty weird. Have you email or called our Tuning Specialists at Bama?
