I think it doesn't work with the early 03 models. Not 100% tho.

Everyone else should be good

 

I have osiris and LOVE it. my maps:
1) 93 performance (for TX)
2) 91 performance (for KS)
3) 100 Shot Nitrous (3300-6600)
4) Economy Tune (4500 rpm, 13.5 afr)
5) Valet (35mph, 3500 rpm)

 

You should take out your ECU yourself, you can find a DIY on AlteredAtmosphere.com, send it to them and have them give you a tune. They do the best work, IMO.

 

so if you on map 2 and the set light blinks 5 times are you on map 5 or 1?

 

Wow... did they sell you or what? Since every car is different, no preprogrammed reflash can match a good dyno tune with the car physically on the dyno. They can get the tune down over time, if you keep sending them your ecu over and over again, if you have data logging. Otherwise, the tune you get from them is just a guess or an estimate, and will not be 100% accurate.

 

For real. I don't care how good their system is, the specs and tolerances are different on every single motor and nothing can beat what you get when you put it on the dyno with a knowledgeable tuner. A preprogrammed tune is by far better than stock, but not optimal for YOUR ride

 

One push and one blink for map one. Two pushes and two blinks for map two. Three pushes and three blinks for map three....

It doesn't matter what it was on before, it starts over each time you set it.
