Help with datalog need a few pointers
The dashboard is saying map 4 and the switch is saying the same so I am not sure. I will check that other stuff when I get a chance.
The boost map is set to ECU because I have a MBC. I will probably just change it to 0 though.

MalibuJack -
Attached are 3 runs I just made. Temperature was about 70 degrees w/ a humidity of 39%.
I noticed that I'm now receiving more knock than I was from the other night. I'm assuming this is because of the temperature? If you could suggest some timing/fuel changes, that'd be awesome.
BTW - I tried uploading one of my runs with the Dataloglab program and could not get it to show a power graph.
Thanks in advance

Some more info on your setup- and situation would help..

My boost is set to 1.35-1.4 bar. I still have my mbc installed, haven't got around to installing the ABC.
As far as my setup, it's just a cone filter, mbc, txs downpipe, stock cat, txs cat-back and the UTEC.

Also did you fill up on gas recently? When you are more tuned bad tanks of gas will be alot more obvious...
I don't think it's the gas, I notice that I've been getting knock in this same area ever since I've installed everything and it knocks a lot worse in the day time. Worse enough that the car stumbles. Ever since my knock issue, I've been just running it on map position 0. These logs were done on map 1.
BTW - Thanks for the help Spec C, I really appreciate it.

Keep in mind in stock mode the utec will not listen for knock nor pull timing..

The stumbling is the timing being retarted over a certain amount of crank cycles..
I would try and tune that knock out.. The 1's could be engine noise but since they are in the same area as where you get the 3's it is most likely mild knock..
Lemme see if I'm understanding you when you say theres a jump in the timing (Sorry, teh n00b). In the first 2 runs, the timing looks to be advancing progressively almost evenly as the RPMs increase, which is what it's supposed to do, right? But in run 3, it goes from +10.6, down to +6.4 and then back up to +7.1 and then jumps to +11.6. Is that the jump you speak of? So basically when the UTEC detected the 3 counts of knock, it pulled timing down to +6.4, correct?

What i am refering to is in the map itself, in that area will go 10,11,12 13 etc sometimes a full point jump will induce knock.. The reason you see those fraction of points is because the Utec interpolates the maps..
I am not saying it is definetly the problem but some cars are more sensative to it..
Let me ask you this.. When on the stock BC did you boost start to taper off by those rpms? Now with the MBC does it hold? If it is holding more boost up top that timing in the base map could be a bit much for that boost..
Like i said try and remove a half a point in that area and see if it helps..
I'm glad someone had a chance to look at that post.. I have been too busy this past few days to read some of the UTEC posts..
I'll try to post some insight on this tomorrow when I get a chance to compare your log with my log.. I have a bit of a stumble with a new map I've been working on.. and it seems to be timing related in a particular area where the boost is higher. At first I thought it was a misfire (it very well could be) I didn't register any knock with that stumble, but I did capture a timing jump of about 1 degree, and the fuel map was a little lean at that point.

After the MBC install, it did hold the boost longer. With that in mind, wouldn't the installation of the TXS ABC and the nature of the Stg1 boost map be the same thing? I'm going to try what you suggested tomorrow Spec C, hopefully it works out.
