Your boost is claiming ECU too in the boost map..

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

Hey could you post your timing map also? What boost are you running? From what i can tell with no afr in the log, is that you are either having too big of jumps in timing in those knock prone zones, or running too much boost on pump with those higher timing numbers..

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

I'm just running an unmolested Stage 1 map, you want me to post that?

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.

I just looked at the base TXS map.. You are getting the knock in the same spot everytime so there is a definite problem in that section of the map.. Some cars are more sensative then others to timing jumps, i would either try and smooth the 1 deg jump in that area so it is more like fractions of a deg.. It may very well not be that, and could be you need to just yank a deg out all together, some cars are very sensative to advance, and it could be afr jump but we cant know that without wideband.. You really need to feel out what your car likes..

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.

Try to remove some timing in that area.. Start with a half a point.. If it still knocks i am leaning towards there being too much of a jump.. Some cars are sensative to even a 1 deg jump in timing..

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

But in stock mode the ecu will listen for knock and pull timing when needed, correct? I also don't get the stumbling in stock mode as well.

Yup the ecu will still do its job.. I am just saying the cel will not flash..

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 you are seing is the utec pulling timing because of the 3 count..

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.
