Uprev Tune Issue

Pelemenii · 10-04-2020, 02:58 PM

My first thought also was that the cats are failing, but my Z is very new only 27k miles so I didn’t think it was that, as they should have a lot of juice left in them. I got the burble map with stock cats because I wanted to hear how “bad” or “quiet” it sounds as everyone always says. I was planning to get test pipes some time down the road.

Did the tuner explain to you how the burble/crackle/flame maps work? And at least warn you that they're bad for the engine? I would never have done one with stock cats... they could literally fail the next day.

providing his map has been done by someone who knows what they’re doing, it’s highly unlikely to cause any internal issues..OEMs have ECU tunes that include burbles that are reliable and designed to last 100,000+ miles of hard use.

I would just get the z1 tps and some aftermarket exhaust..

Doesn't matter if it's straight off the factory line or has 100k miles on the odometer -- running raw fuel through a catalytic convertor will cause it to stop functioning properly. The burble-and-pop mode runs raw fuel through the cats. The outcome was inevitable.
