re no maf, you would have to go stand-alone ecu. run an alfa-n tune (goes off throttle position) and vacuum signal for idle (note that the obx unit has a vacuum plenum; would have to adapt a throttle position sensor to the cable throttle linkage) and presume go to wideband 02 sensors, as well as an iat sensor (since no more maf). all the new stand-alone ecus can drive variable valve timing these days.
