I don't get this approach at all. The ECU and FI setup are so vital to the health of your Z
Why not just wait till its FI time? and get a complete bundle with a warranty .?
How would you feel if you turned up a year after having you Haltech done
to pickup your newly Fi'd zed. to be told "sorry, the haltech doesn't do the job properly!"?
If you are planning to go the FI route,....
You HAVE to get both done at the same time, by the same tuner.
No satisfaction, NO PAY! or a free return to stock
