Is there a cheap program & cable combo that lets us upload the OFT roms to remap the ECU on the FR-S?
I hate to buy a $500 tablet for something I might use once or twice.
Thanks

I've used my tablet 1000's of times, not only for loading tunes, but for logging as well as monitoring up to three channels in real time. I have learned how to tune through trial and error with my OFT. The OFT is much safer than cheap ebay cable methods, with built-in checks to help prevent bricking your ECU accidentally.
Whatever you choose, make sure to read up as much as you can before you load anything to make sure you do it safely.
One advantage the OFT has over other options is the Open Source ability to share tunes and knowledge/experience without revealing any patented secrets, or getting sued/pressured to remove what you have posted. We OFT tuners share what we learn, and help out others when they need it. I also own the Phantom Super Charger system, which is a unique challenge to tune for.
Here are pics of the the AVCS Exhaust tables from my tune, and from the tunes supplied by shiv@openflash for use with the Phantom. This is an example of how many changes I have made to extract maximum performance. I always try for smooth, geometrically progressive changes in the tables I make, because I believe sharp, sudden changes require sharp, sudden compensations if other areas, which can lead to drive-ability problems. I drive an AT, which is great for tuning, since the vastly taller gearing means I feel every flaw in my tunes. To get the same thing in an MT, you'd have to start out in 2nd gear, and then skip every other gear shifting.
