NOX is due to it running lean and or hot. When you swapped ecu's, did you disconnect the battery for 30 mins? When you re-adapted , how many miles did you put on it as it will take trionic7 about 200 miles before it sets all the parameters correctly. Put the nodic ecu in there and see what happens. Clean the maf as well, and how many miles are on the maf? If you have the vacuum hoses on wrong, you could be pulling in to much air. Is this a rolling dyno test, did they ahev fans on keeping the car somewhat cool?
