Here's the second UOA on my 22 Wrangler with the Ecodiesel. This has 5k miles on AMSOIL Signature Series DEO 5w-40. The first one was dealer installed oil, no clue what it was, the second is what AMSOIL recommended, European FS 5w-40, Most of the Ecodiesel world is showing great results using the European MS 5w-40, I figured I would see how the DEO works. This is using an Ecoguard oil filter. It's my understanding this engine likes to shed aluminum. We will see. So far I don't think this is too bad.
I'm surprised nobody seems to offer a solution like the start/stop device I put in my new truck. Remembers my setting when shutdown. And while it still starts up in start/stop, it stores/evaluates what mode it was in when shut down and will change it whithin a second or 2 of startup. It'd be nice to have something like that for the DRLs.
I will be doing that for sure, but I need to solve who has/ where I can find a bidirectional scan tool that will support OBD 1.5. I'm kicking myself because I ebay'ed a Snap On MT2500 that I didn't think I'd ever need anymore. D'oh!! I'd rather not buy another, so I'll contact a few local shops to see if they have one and how much they'd want to do the procedure. I'd rather have the ability to do it myself... I wish there was a modern tool that could do it all, but I'd have no idea what to buy.
The theory with the pulled timing is that it mimics a rich condition. The delayed spark causes incomplete burn and the O2 sensor picks up low oxygen levels. That's interpreted as a rich condition so the PCM pulls fuel and that shows up in the deeply negative fuel trims.
