im trying the help out a guy in town car get his car dialed in, he bought the car allready modified. he has a pocket logger that sucks ass. you cant log runs and review them from the pda, you have to dock it to a computer, so i tryed to read RPM, front o2 & timming off the logger while he made 10-15 2nd and 3rd gear pulls, but to no use. we set his safc from on high/low anywhere from -20% to -12% (he kept telling me to zero it out, i just told him to shut up and drive). I couldn't get rid of his fuel cut around 6000 in 2nd. so i was hoping someone could give me a good base line on the SAFC1 for high/low's

the car needs alot of help, its slow as shit. his timming droped down into 8-9 range in the higher rpms right before, durring fuel cut. i set his boost to 15psi. i forgot to mention that.

dam scottsee i wish i could help you but i dont know to much about the afc settings.i need to get up to speed on it but the maft i know pretty dam good.let me look around and see what i can find for ya!

i figure a good place to start is around -30% on high/low. and go from there. what do you think?

450/660 - 1 is about -32%. That will compensate for the injectors, and that is where you should start. That should provide stock 9.5:1 AFR, but timing could be high if you are not staying over 2.1 g/rev airflow. If by zeroed out you mean he wanted to run at 0s, it would be 32% too rich. I'd be surprised if the motor even ran halfway decent.

thats why i told him to shut up! im going back over to his house on tuesday to fix his TPS it shows 92% at wot, he also seems to think there is a boost leak. i'll get some logs on a 3rd gear with -32% high and -32% logging Rpm, front 02, timing.

The ECU considers anything over 90% to be WOT anyway. Set the TPS so that its jsut barely on zero (almost on 1) percent with the throttle closed so the idle switch functions properly. Then see what you get on the high end. Some poeple make the mistake of going to far negative (still shows 0) reducing the reading at WOT. Either way though, the ECU will still function the same over 90%.

A boost leak will make it even richer than it would otherwise be, so I would definitely let him take care of that shit before doing any more tuning.

Good luck with it.

he has a pocket logger that sucks ass. you cant log runs and review them from the pda, you have to dock it to a computer,


Is this the software from www.pocketlogger.com If so, you can read the logs on the PDA. After you create a log, click on the bottom right side of the screen. It looks like a magnifying glass. This will take you to the saved log screen. Then just click on any log to bring up the graphs. You can then drag your stylus around to see the #'s. It's a little clumsy at first, but better than going through all of the shit with the computer and PLViewer.

If it's not the software from www.pocketlogger.com , than nevermind! :smile:
