Post any questions to this thread. I have not run this modification yet in my vehicle as its only just been discovered by a forum member, but all tested well on the bench

Matt,
I noticed on page 34 of Nistune software Users Manual regarding MAF mods that 2 parallel resistors & R201 was removed in the previous mod,
Is this still required for the 87-89 ECU's as well as daughter board pin14 removal?

Kind Regards
