I would be thrilled to get a count of 17,000, never mind 70,000. I don't have an Insight, but I do have a dashhawk and I seldom see the count get any higher than 8,000. Around town, seems to do a regen in the 6,000 - 7,000 range. On the highway with the 5th wheel, it's in the 8,000 - 9,000 range (3 exhaust sensors running around 850 degrees).
Seems like the harder you work the truck, the less frequent the regens. Going through the hills in north western New Brunswick, I actually saw 12,000 (3 exhaust sensors running around 925).
The dashhawk has a regen filter, regen filter target, and soot load pressure. The regen filter target never changes and has been fixed at 4. 5. The regen filter varies between 2 and about 5 (except when the truck was new, it actually made its way to 12 before starting to fall). The soot load pressure appears to be the exhaust backpressure due to the DPF and varies with boost and time since last regen (usually 0. 1/0. 2 at idle and I've seen it as high as 6. 0 when climbing hills with the trailer in tow).
