UnitedMotorsport 55 Posted March 23, 2008 Report Share Posted March 23, 2008 It'll run fine, just not make as much power if you have an early OBD1? Link to post Share on other sites

UnitedMotorsport 55 Posted March 23, 2008 Report Share Posted March 23, 2008 EARLY OBD1 as in the 6 pin maf. It is a misconception that all 2.9's are OBD1. Altho all corrados were as far as we know,Which config do you have? coil pack? 6 or 4 pin maf? Link to post Share on other sites

UnitedMotorsport 55 Posted March 23, 2008 Report Share Posted March 23, 2008 I just looked through your engine install pictures and see you have a distrubuter, just as you replied.Unsure on the extra pin, it could be an air temperature output. Link to post Share on other sites
