I remember the epic thread that was averaging a post every few minutes for weeks and months....
The experts (you know who you are) were stating they will never come up with a fix. WRONG...
The experts, if there is a fix it would require urea injection.... WRONG
We knew they could fix it early on, because it had already been done by CR. They disabled or bypassed the triggers that sent the car into "no test mode" or "cheat mode" to keep it in "test" or "dyno" mode..... which passed EPA standards. The performance and MPG was documented. It lost a few MPG's and 1/2 second on the 0-60 mph times I recall. The EPA cert and issues of reliability took about 2 years, and you get extended warranty...... Still driving Heidi (2010 JSW with 40K on 2013 engine...). My plan to keep it for another 3-8 years is happening with an extra $5K in my pocket.....
