So far I have only really read my ECM and made the changes in there, simple stuff so the SES doesn't come on, speedo etc.

What I want to do is flash in a complete F-body manual transmission cal so I can get the AC and reverse lockout to work. What I thought I could do is use the cal from another car to modify and then put in my car, but it looks like I have to spend 2 credits to be able to save the changes to manual car file? I already spent 2 credits on my current ECM and I didn't really want to spend more, I will if I have to, but maybe there is a way around that? What I don't get is that I thought the HPT doesn't have the ability to change the VINs, so if I spend the credits on the manual car file and flash my ECM, won't I still have the 4.8 truck VIN still?
