Fair enough, but Crankcase pressure in all but the most worn engines I have ever measured would not even register on a standard PSI gauge. Horrible engines would not likely get over 1/2 a PSI (inches of water using a manometer). That and the pressure would relieve through the PCV system unless it was clogged.


You would be much more likely to see oil past the rings in that case.

Thanks for the suggestion about checking the automatic transmission mapping, sorry it took a year to get to it:



That was easy, and it helped me understanding that there are code tables loaded for different transmissions in the same ECU. This really helped me make sense of some things in Engine Coding Part 2...

I did find that the auto mapping was very similar to the manual mapping, except for one very important difference: at low rpms there was a jack-rabbit type shudder. Also a fault code for lack of communication with the auto trans control module.

I switched it back to manual mapping, and checked this suggestion off my list of things to try.

There was another suggestion that had been nagging at me though... [continued in part 2]

"Just alter the boost maps to atmospheric." Brilliant!

I forgot to mention I had brought the NarfMOBILE out of storage for the Great Lakes Mistake Lemons Rally (details here:Lemons Rally: The Winners and More From the 'Great Lakes Mistake')

I enjoyed driving it so much I got to thinking about how it needs to pass emissions in September. I had three options that I could see to get rid of the check engine light:

A) Most Expensive: re-install turbo, and all those pipes, and have all those issues all over again and, what about the timing belt, and, and, nope - not going there!

B) Less expensive: get a stage 0 tune, get laughed at by engine tuner or pay extra to have a flashzilla shipped to me, seems like a foolish waste of money

C) Practically free: just set the boost maps to atmospheric, YES, that should work, no boost request, no boost available, no harm, no foul, no check engine light, right?

Okay, option "C" it is then. Only problem is, how to download the code from the ECU in the first place? After reading a whole bunch of documentation I finally found a mention using the "Galleto 1260 interface" so I punched that it into Amazon.ca and...



$23.99 in stock in Canada and free shipping? I couldn't believe my luck! Could this thing possibly work? It was worth a try...

Two days later I had this super nice quality cable, and more importantly, the software CD, in my hands:



I plugged it in, and tested every button on the panel, including the download button, which is actually the upload button, whatever, IT WORKS!!!



Now I had file I could open in EDC Suite:



And now to "just alter the boost maps to atmospheric"...



Yup, I just hit "select all" entered "999" and "fill" then clicked the little lightning bolt, hit save, saved the file, uploaded it to the ECU by hitting download, and BLAMO! My ECU no longer looks for boost! I am still laughing 2000 km later with no more check engine light.

I can now add "turbo delete" to anyone's engine tune. LMAO!!!

This is the best part:



I had to go back and review the item on Amazon.ca:



Good times!

Haha, they do, but I prefer games with better odds:



This means I can update the registration stickers for two more years of a sweet handling, comfortable ride with ridiculous fuel economy!

Winning!

Ridiculous fuel economy? My ALH is stock and I regularly get high 40s, low 50s mpg. Just a little bit of coasting and traffic light timing, along with no tailgating. I'm not sure you can attribute your improved fuel economy to a lack of turbocharging, especially since the turbo improves the VE of the diesel engine.

I meant ridiculous fuel economy compared to our gasoline vehicles.
