Hmmm...seems like you're running ultra conservative timing at WOT. Your total timing is even less than the Cobb OTS 91 map Primary+DA A in many cells. For instance, at 6800rpm+2.90load the Cobb Primary+DA A is 28 degrees while you're only targeting about 26 degrees there. Why are you running even less timing than the Cobb OTS 91 map?

It is more like the Cali map..

Hmm that spread sheet looks familiar? But anyways, give something like this a shot. You may want to lower higher rpm/loads this was something I just put together quickly to display what I am talking about. You still have way too much timing down low IMO.

[flatthump]

Hmm....well I did something a little different than that but it worked. Im not running straight 16*. It tapers as the load increases from about 19 degrees to 16 degrees. But only untill 1.9 load.

I think I can tune out some of this 'bucking' at part throttle where im inbetween 1 and 1.9 load. other than that it worked perfectly. I hit some of my best load numbers tonite: 3.49..didnt go into the 2's untill after 5800 rpm. Im very pleased thankyou.

Yea, those are just say 'testing' numbers to get an idea of what I was talking about. There should be way more saftey and smoothing built into your timing curve and trend. Wow I think I am on to something here. Crazy how you can solve a knock trend at 5000+rpms by fixing a timing trend below 3000rpms and 2 load. Ill do some testing today to see how much timing my car will take before I see any noise.

Well my timing is working great, but at very light loads like .44/.80 or less accelerating normally from a stop light the car is now pulling timing. My timing is stock below 1.0 and above goes up to 16d. I also noted the car is really rich(I have my second O2 zip tied but plug-in).




Another example.

Yeah...to be quite honest, it actually annoys me

I'm going to see how much more timing I can add inbetween 1 and 1.9 load untill it starts to pull timing again at 5000.

First off, I would suggest logging less parameters. It is slowing down the log rate and you are not getting enough resolution to get an accurate look. When you hit the - ignition timing value, it looks like you were getting off the throttle. That is normal sometimes due to the fact that the injectors cut out. Watch your DA values rather than your actual timing values. If the ecu detects knock it will more than likely show you negative DA rather than negative timing. There are thousands of tables in the ecu that change things for decel and accel. Does you knock learning table show anything severe? By severe I mean more than say -2+*. Next to try and tune the richness. You will most likely need to do a seperate logging/tuning session for your MAF calibration. Due to the fact that you have you rear o2 out, it would not surprise that you are running rich. This has been discussed before. I believe it will soon be possible to turn off the rear o2 signal to eliminate any bias it has towards the fuel calibrations. The fuel and ignition tables in the ecu are literally some of the most complicated calculations you would ever see. It references a ton of different RAM values based on feedback from a bunch of things including sensors. Thats all I got for now. Gotta prepare for the track tomorrow hopefully.

All zero's in the KC table.

My rear o2 sensor in in. The wideband 02 is right at the bellmouth of the DP.

Thanks Crystal, I already lowered the loggin parameters. DA values are set stock that means 0 at that load point. The ECU pulls the timing when I start applying gas. My Knock Learning table is clean all 0. For a second the car feels like a carburated car when it's flooded and then it goes like nothing. I will move my O2 to the downpipe before starting tuning fuel.

Oh I thought he was replying to me...woops.

Try tinkering with your TDC tables then. It may be possible as I mentioned when I posted it, that it is a little too low for a drivers taste. Also check out your boost tables. An unsmooth transitions will cause it to stutter slightly. Lastly tinker with you CL/OL transitions. Mess with the modified loads and TPS and see if you can get it to smooth out. This is a huge problem with the 07's IMO not to mention there funky AVCS settings which you should actually mess with slightly. Again its the art of balance. Now you see why we go crazy sometimes because one change in one table means a dozen more changes to other tables to accommodate our needs.

Will do, thanks
(btw good luck tomorow)

Hey flatthump, did you fix the problem. Mine started again today I think because of bad fuel. I need to stay away from that Sunoco station.

[flatthump]

I didn't run that map for too long but yes, it fixed the problem. I have made a completely new total ignition map with much higer targets. I took some timing outta the 1.0-1.6 load sites but barely any at all. I dont have a problem with DA being pulled but now I have a problem with reaching my targets. No DA is being pulled but the timing I data logged isnt matching up with what I have in Crystals excel worksheet.

Lol..I've heard 3 suby's with loud exhausts ripp'n it while posting this..
