50Trim, 680s, SAFC, e85 mix Log

[DSM_PWR]

Let me know what you guys think.

Wideband read 11:1-11:5 from 3k-7k
Running a 50/50 mix of e85/93 octane

RPM Timing o2
2644 20 0.9
2925 16 0.92
3253 12 0.92
3625 10 0.94
4097 10 0.94
4617 10 0.94
5121 12 0.92
5625 15 0.94
6074 16 0.92

Timing from 3k-4600 make me nervous

You need to log another run with a lot more data points. One sample every 4-500rpm is no bueno. There is a big part of the picture missing. It's impossible to tell if you are having timing pulled in between the points shown, and recovering before the next sample. And take it up to at least 7K rpm.

Painted with the broad brush that it is, however, this does not look too bad. The timing dip to 10* is OK (I go as low as 6* when my E3 16g hits), perhaps not rising quickly enough, though. And I usually like to be in the 17-18* range by redline.

Try another pull or two with a percentage or two of fuel added from 3-4.5K and see what happens. And change up your logger to collect more data points, and turn off all the ones you don't need, like the stock o2 reading. When I log runs, I only collect rpm, timing, and airflow. That's enough, with your WBo2, to get a great idea of what's going on.

yea my logger sample rate sucks trust me. This is as good as it gets, reason being i only logged rpm/timing/o2

I hate the fact that i can never see anything passed 6k but im willing to bet timing should redline at 18-19degs

What logger program are you using and what Palm model are you running it on?

[DSM_PWR]

i got the software from OBDloggers.com its called "Proscan". and its for my laptop.

Anyone know of a free software for obdII that logs IDC? and better sample rate?

I use TunerStein for Palm. There *might* be a Windows version, or a Palm emulator you could run on your laptop. I get pretty good samples with it. Logging timing, rpm, and airflow, I get about 1 full reading every 150-ish rpm, once boost hits and rpm's are climbing rapidly. That's plenty tight for me to get a good look at what's going on.

AFAIK, there's no software for 2nd gen OBDII that logs IDC's. The only way to do that on a 2g is with DSMLink or some other comprehensive ECU software. You will have to resort to math to figure out how much your injectors are being taxed, and then it's only a pretty close estimate, not exact.

I was hoping there was a way that we could increase the number of samples / second you are getting, but I have no experience with laptop OBD-II logging. Are there any settings in the program for data transfer, such as byte timing, packet or byte delay?

Matt is correct, 2g's don't output that data to the OBD-II port, so without DSMLink, you're stuck at guessing.

[DSM_PWR]

aw shucks!

well ill take a look at tunerstein to see if they have a pc version. If not i guess im stuck till i get DSMlink

[matthewdesigns]

Freeware palm emulator.

What are your IDC's at by the way?
