ProphetVX said:Series 2 VX's if ecotec's have an ECU which can't be tuned.
It uses memcal technology whereas the earlier models used flash memory. There currently aren't any tools that allow tuning of a memcal, unless you get a piggyback ECU from companies such as haltech, motech etc. They come with their own issues that need not be discussed here. Its an expensive path to go down, as the piggy back ECU itself would cost up to $1500, then you have a very complex installation ontop of that.
To "downgrade" your ECU to flash also is a tedious task, requiring a major overhaul of your wiring harnesses, instrument cluster etc.
Obviously you need to retune your ECU to handle the manual as it will cause the car to run poorly without. So as you can see its a very difficult path to go down with the series 2.
If you're just going to get a shop to do the work for you, and still haven't purchased the car, I'd investigate costing before you commit yourself to the purchase.
You may be better off holding off till you find a series 1, or a VT that is to your liking if your heart is set on a manual.
Can you just use a vt ecu in the vx?
