Huge plus having the Polar input to compare stock tune with Kerma non delete tune.
I finally took er' out with new Kerma non delete tune for a 60 mile freeway stretch. The Polar showed I was JUST ready for another active regen with 150 miles since last one. The DPF is only 7k old and. The stock tune never passively keep soot level burnt off, even on 700* freeway runs. Here are a few things I noted:
First thing I noticed was it sounded different. Not bad, not good, just slightly different.
Started & idled just as good as it always has.
Slight power boost feel, havent put it to the giggle test yet but it always felt strong.
Normally a 50 mile freeway run leveled out @ around 45mpg ish... Today the lie-o-meter read 50.3 @ the returning offramp and "seemed" to be slowly adding mpg still. More trips needed though to see.
The soot load stayed @ 0.0 the whole freeway portion. It went up to 0.5 midtrip as I idled thru Wendys drivethru, but passively burnt soot off on return trip.
Joy meter hit a nice spot everytime the car idled by reading much lower EGT's. Probably 50*+. In the past I made it a practice to shut a/c off & idle to bring EGTs down below 400*. Normally would only take less than 30 seconds but the temperature would stay over 400* if the a/c was on! Now 375* ish with a/c, 315* with out
Dont forget to add your 2 cents to the poll @ the beggining of the thread
