Just some insight on Lyndon Wester, he wrote and sells and licenses his own ECM tuning software for GM vehicles, he was one of the first if not the first to crack the OBDII code back when GM switched in 1995. He is working on a full blown solution for the Bosch ECM and that is how he can do what he is doing. You can download the tune with HP Tuners but there are parts of what he did you can not see or change with HP tuners. If you check with any other tuners who are doing GXP tunes, all of them require you send in the ECM. On other vehicles and the NA, Westers sends out a replacement ECM and you send yours back. GM won't sell the ECM's for the GXP so you have to send it in. I will sacn every car before I install the tune and send the scan to Lyndon. He has several authorized independent tuners in the states, check his website. They use his software to tune Vette's and the like. If one of them wants to buy the license agreement for the Solstice you will be able to drive in and get a tune. That is up to each individual shop. If a Westers shop is near you you could have them call Westers about becoming an authorized installer for the tune, that is up to them.
Thanks for the info. Makes sense. I was mainly wondering if it was a tune I could just pay Wester's for, download it, and install it with HP Tuners. Sounds a little more involved than that though.
