Just went logging. Help with SAFC Settings

[b11dragone]

Ok guys. I just took my logger out for its first run and these are the results.

RPM O2 Timing
824 .74 12
2168 .94 10
3352 .98 7
4952 .96 9
5228 .98 12
5680 .96 14
6112 .94 17
6324 .94 17

What do you think I should do for My SAFC settings. Thanks for the help. Oh ya why is it so hard to get the plviewer on my computer to view my logs. Thanks again.

your timing is contiuously advancing... and O2s are fairly good.... dont do anything.

We need to know a lot more info.
1) Relevant mods (fuel, turbo, psi). If you post them in your post them people don't have to look under your mod list which could be out of date.
2) What your current safc settings are, injector size.
3) What gear pull was this.

Did you convert your log to excel form from plviewer. Because you don't have enough data points. I mean you go from 2168 to 3352; 1200rpm without a sample? Either you need to get the sample rate up on the logger->ecu connection, or you didn't post the entire log run. Other than that, the mini log looks O.K. .98 and .96 might be a little high o2's, but timing seems to always advance and not get pulled.

I haven't touched my afc settings so everything should be 0'd out. I haven't even changed my throttle points. Stock injectors I didn't want to touch it untill I got the logger. I think my samples are alittle slow but it is at 10per secound. I did another run and here are the results with less gaps. This was a third gear pull at about 14psi. How do you convert to excel? Thanks

Did you at least set the safc up to work with your car? Like set it to "karmen" meter, and "4cyl", and the "arrow going up". Then you just have to set the throttle points (30% and 70%). 10 samples per second might be the best you can get. Play around with byte timing and see if you can't get it up more. To convert to excel, open the log in plviewer, and then under "File", there should be "convert to csv". Do that, save the file somewhere like your desktop. Then you should be able to double click on that new file and excel will open it up with all the data points in it.

The 2nd log looks pretty good. I wouldn't go changing any of the fuel setttings on the safc. The stock ecu is doing a good job just the way it is.

Ya I initialized my safc. I am not retarded. Im pretty sure my car would be running like crap right now if I didn't. I just wanted some tuning help with those numbers but if it looks good that is great. I just didn't know what to look for. Thanks.

My car, with basically the same mods (stock fuel pump) I'm leaning out 5% up top on the S-AFC 2

 

[b11dragone]

Thanks that sounds good. I lean it out about 5% up top and do a log. Ill get back to you guys with those logging numbers later when I get out of work.
