View Full Version : Ecu programming questions

02-27-2014, 09:21 PM
Friend recently got a 99 1.8 avant Quattro, came with 2 chipped ecus, one with newspeed stage 1 and one with unitronic stage 1. The car is only running a peak of 9 psi on either ecu and we've been looking for and not finding boost leaks. Scanning for codes all we get is computer programming not completed, this is with both ecus. Car runs good, no misfires or anything, feels pretty strong but not strong as it should.

Why does it say computer programming not completed? What does it mean beyond the obvious? Car runs the same with both of them. Newspeed chip is on original ecu and Uni chip was an extra ecu that came with the car
