for the conversion i used a GTS Link
after swapping engines i have gone back to a factory 25det ecu (mostly coz it was a lot easier to do so to get the car running asap)
knowing what i know now, i should have just swapped injectors and used a factory 25det ecu for the conversion. (the afm and wiring loom are all the same
in the r33) that would have solved all the tuning issues/time. and if it pinged u can just retard the base timing from the cas.
the perfect mod for a 33 gts4
