I will drive from Mpls to Bozeman on Sat. (gads is that gonna be a long day) Then drive to Ellensburg Sunday. I'll be looking for beer and burger...then a motel.

I'm camping out in Steve's backyard....he's going on a DATE. I think I can make Boz. Billings is where I'd normally pull the pin, but I've been told the wagyu burger (rare) and a pint of a red IPA at Montana Ale Works is something I shouldn't miss. It may be late but I'm going for it!

We got ourselves a brotherhood trade here. Steve is going camping, we all know that code words for something else, but he's leaving me a growler of a local brew, and I'm leaving him a coule 4 packs of Surly. Then on the way back, next Saturday, I think we're gonna meet face to face.

Cody, if you're in Bozafornia late on Sat..we could still meet up....I'd like to meet you. You can get my cell from Rich.

I tried calling him about an hour ago, just waiting on a return.

I will be in Bozeman all night tomorrow night.

I'll PM you my cell phone number (which I never take with me since it's technically my "work phone"). I'll give that number to Steve too....since the house number I gave him won't do either of us much good once I'm on the road.

Cody, I tried calling you back. What do you have, dial up internet out in the sticks?

If we don't talk tonight, I'm here. 307 N. Broadway in Bozeman. I'll be ready when you get to town tomorrow, give me a shout anytime tonight or tomorrow. Breakfast at Soby's or the Western, I'm buying.

Well, I finally got to meet Cody in person, and he's a great dude. We put a new tune on my Hydra and...no change in the cold start smoke. We figured out that the #1 injector was warming up the exhaust manifold slower than the rest, including the #2 (front driver side).

Contrary to what I thought, he's had experience with injectors running too lean causing the white smoke. He's leaning towards either a mechanical injector issue, or possibly fuel pressure, especially since #1 is the last to get fuel on that side. #8 is the last to get fuel on the driver side, but that one warmed up the exhaust manifold much more quickly.

Prior to replacing the injectors, I had cold start smoke. I was sure, however, that it was related to the two blown injector o-rings on #3 and #6. I was really hoping that this was tune-related, and was coming from a different source than before the injector swap, but that may not be the case.

We ruled out tuning finally, compression has been ruled out, the entire glow plug circuit is ruled out, the UVCH has been ruled out (by metering injector resistance at the 42-pin).

So, next step is to get a gauge setup for fuel pressure. It that looks good, then it's on to injector swapping. Though Cody would say to quit typing and start swapping injectors - he could've had it done by now.

Well that is a mixed bag of good and bad huh?

Good.....meet Cody, try one of his tunes and eliminate a few variables that aren't causing the white smoke issue.

The Bad.....you still have a white smoke issue

Good luck.

Steve's a heck of a guy. I did flub up on his tuning though......


Steve, PM your email address and I'll send you a different tune to put on your Hydra. Remember our little lack of power on the initial test run? Well, I fixed one problem and caused another.....I thought of it a few minutes ago and had to recheck the math in my head.

My calculation was skewed on the second test drive. If you're still around, give me a call and I can come load it up today yet.

Bad stick eh? I've danced to that tune more than once. I don't remember, new or reman? I'm not saying that will matter, I'm just curious.

If you dive into the VCs, check what the injector torque is before you pop the stick.

I met up with Steve and his GF last night. Elk burgers on the barbie...awesome. It did notice Steve left one thing out of his reply though. His version of AE v12...misreports the MAP. I guess Cody had some whiz bang Ford IDS or something and the MAP checked fine.

Crud. I'll work on a Scale to work around the problem.

I'm glad to hear you made it to Blowsman.....but you never called me once you got there.

When are you coming back through (if you're coming back through this way)?

Sorry Cody...I must have spaced that part of the conversation..zombie like after 800 miles. My plan is to head that way Sat...Likely lay over in Billings.

When you get to the Livingston/Big Timber area, give me a call and I'll tell you how to get to my house.
