Don't risk it. Get a Utec, or if you have to, an Accessport.

 

many of us have used opensource successfully for years...

I've said it before and I will say it again, if you aren't well versed in engine tuning and dynamics, AP is your best option.

I personally don't like the UTEC interface, but thats probably because I'm used to the opensource tools.

 

^^^This

if you have the set it and forget it mentality, go with the ap. If you are like me and are willing to dedicate DAYS of time into reading, tuning, and datalogging, then opensource is the way to go.

You could also pick up the cable. Then buy a Clark map. Which will be a great base map to learn from.

 

As I've said in the past, lets not forget that the AP2 is no longer a set it and forget it only option. Cobb gives you access tuner race along with their AP so you can create your own tunes with the AP2.

 

But if your going to create your own tunes, why bother spending the 600, when you can do it for the price of a tactrix cable. Does the AP2 offer anything that romraider doesn't?

 

As much as I dislike AP, it does have it's place in the Suby aftermarket crowd. It offers map switching, w/o a laptop, a scantool for check engine lights, 0-60 and 1/4 mile estimates... all w/ a small, compact hand-held device. Romraider, Learning View (from Merchgod) and help from Airboy, you can get all the above. But you need a laptop, and some it is not as user-friendly as AP.
Now, AP offers Speed Density. Get rid of your MAF and just use your MAP sensor. Again, there is someone on Romraider working on speed density hack, but all of this is user-beware.
I personally bricked my 05 FXT ECU, I am working on a set up to force SH BOOT MODE, so I can reflash it w/ a base map and then sell it. Live and learn, Freon, finally explained that if you have an error, in the middle of reflashing, to NOT turn off your ignition, reboot your laptop and reflash the car again.
The problems start when you have an incomplete flash and you turn off your ignition. I wish I would have known that 4 months ago.
