If anyone is still interested in this topic, I passed emissions test today. Basically I put 1.25 gal. of alcohol in the tank, used a vortec timing table with 5 degrees taken out from both tables. The...

Well I ordered the other wideband gauge and it should be here tomorrow. But in the the meantime, I couldn't stand having spent that money on the first one and it wouldn't work. So, I sat down and...

Shit, you're right! I guess I just saw they both had 0-5V outputs and assumed they were the same scale.:doh:
I guess I'll see how fast I can get the right one in. It cant be rescaled that I know of,...

Here is spike test bins and logs. I added pics showing log and gauge differences for each to

Right, and 72 is what I had started with, before I started to max out my fuel tables and was told to lower flow rate in the bin to get more room to work with. That's how I ended up at 59. I just made...

Ok. Verified fuel pressure. 18 psi with pump running, 17 psi while cranking

I will do this test today, although I think I've basically done this just with changing desires afr instead of injector flow. Flow was set at 59 because I was told when I first built this engine that...

So I moved the output ground from an engine ground to a sensor ground and nothing changed. Here is a short log and current bin, along with a pic showing the differences. It's like this all the time....

Dave that's the same gauge I'm using. I'm wondering if my output ground is what is messing it up. Because the gauge itself is reading correct but it really if ever will go below 15 in the log. I set...

So, it's not battery voltage. For some reason the gage is displaying correct afr but the data log is is always showing about 1.3-2 points higher. Anyone had this issue? Do I need to try a different...

So, I figured out this morning that my logs aren't actually reading WBO2. For some reason it's still logging battery voltage. Feel like an idiot for that.
I must have missed a setting somewhere?
I...

I appreciate the help so far Dave. My fuel tables are now starting to exceed 100 at fairly low RPM, and I still need more fuel. I've already lied and set injector flow rate as 59.... is it ok to...

Thanks, I figured it out though. Mine was adding columns for lambda and wbo2 voltage so it threw the columns off. Just left those out when exporting.

Now my question with this process is... I've...

Are you saying that based off Dave's screenshot or my logs? I don't think his screenshot was of any of my logging.

I'm not to good with Excel. What is the easiest way to copy the csv info to the worksheet? My csv from a log today has columns in a different order than the work sheet. I copy and pasted individual...

Thanks Dave . I'll take a look this afternoon

Here's a little test run with the WB. Everything looks lean. Where should I be making changes?

FAST I think you're the one that helped me get this thing running a few months ago.

I finally got a WBO2 put in today, about to go test logging. Hopefully I did it right. Lol

So had already...

I have a true dual 2.5" exhaust and they put a cone around both of them when testing. My O2 sensor it heated and before testing I'm running it up and down the highway a couple times to make sure...

Should have mentioned, I started the log before I pulled into test facility and threw the laptop in my backpack. So, the test start right after the truck shuts off then back on. ;)

So it will run on my PCM? Heres the results I got today. Sorry I'm just hesitant to throw a file on my truck without understanding what it is

What is that? Difference tool shows a bunch of undefined line items

I'm still new to the tuning thing and I'm due for emissions test. Recently put a 383 with cam, aluminum heads, and ported throttle body in my 93 K1500. Has no EGR passages. Test is on rollers with a...

Ok, so I finally got brake issues worked out so I could drive the truck. But the ignition timing is making me feel like a complete idiot. I keep adding timing to open throttle table, or taking away...

Little update: I got the knock sensor replaced this week and got the truck running good enough that I drove it to work a few days. Had a few issues I was having trouble figuring out. But, Friday, my...
