[QUOTE="cheeser, post: 16233094, member: 142342"] VMP re-reviewed my datalogs and provided me a tune that would address the readiness monitor issues, in addition to turning off the P219A reporting ability. They verified there wasn't anything wrong, in addition to this only popping up once every few hundred miles. I didn't ask if they had the ability to widen the acceptable variance instead of just turning off the reporting function for this one code. I downloaded the updated tune to my SCT X4 device last night, but when I tried uploading it to the car, a 110D8 downloading error would pop. I couldn't return car to the stock tune, nor upload the new tune. After looking on different forums, some suggested tuner needed an update, while others mentioned the tuner saw low voltage and self destructed. I decided to update my SCT X4 device (took 3.5 hours), and unhook the battery. I hooked up a battery charger and tried again....finally worked. Had to reload stock tune first, and then upload the new revised tune. Drove it a bit last night and then to work today...all of the readiness monitors finally went green. Great since I can now pass emissions. Car idles and runs fine. I'm a bit down on power (560 RWHP) as VMP didn't get too aggressive as we only have 91 octane. Keeping my finger crossed no other gremlins pop up, but happy so far. [/QUOTE]
