Re: Good news... kinda
Interesting. Looks like it's option 3. Something between the time you did your first wb sensor test and the time you did the dyno changed your a/f ratio.
Can you use emanage to return the numbers back to 12:5 - 13:2? Then, drive for a couple of months and see if it stays that way or goes back to 11s?
And, can you figure out if there is anything you might have done to have changed the a/f ratio?
Keep us updated because this is very interesting data. Thanks.

Guess I'll find out soon enough.

I have all the charts in winpep format, but would rather distribute them to each person to post up themselves if they wish. Doing a screencap, resizing, and hosting all of these runs would be quite a project. I'll gladly send these to anyone who'd like to take that on.
Besides, the charts really wouldn't show much unless you put them on top of eachother to show differences between cars or baseline runs. I can surely do some individual requests like that.

Here's an interesting one...
All three of these are stock Z's (two 04's and a single 05) making about the same power within the margin of error.
However, the 05 one (green line) seems like it's got a richer map than the other 04's.

Wow, after reading through this thread I can imagine why some of you guys might be disapointed with the #'s. Makes me wonder how I would have reacted if I got #'s that were not up to my expectations.
Hopefully the next run will have more favorable weather and everyone can compare dyno's again.

More interesting results
Well, I reset my ECU and was able to get in a couple more WOT runs on the way back to work again and the results are quite interesting. Below are the graphs of both WOT runs yesterday as well as the ones today after resetting my ECU. They are virtually identical +- .2!
Looks like it may just be a case of adjusting the numbers on the eManage to get into the good range again.

Your A/F looks a little on the lean side. Have you tuned your SAFC yet?

Do any of you have the actual Dynojet run files to post?
Also that nitrous A/F graph looks terrible. How is this dry shot setup?
Dyno posting etiquette is to post all numbers in SAE correction and make the runs in the closest gear ratio to 1:1. Which is 4th gear in these cars.
