hope this works

What MAF/chip display option do we need to use while viewing? LC-1 WB right...?

The first file (004) is got some electrical issue going on...... for the longest time... there is no 02 milivolts reading.... then all of a sudden (around 21.5 sec) .... as you roll into the gas.... you get a reading.

Your MAF reading looks real low...... maybe you have a translator and LS1 MAF meter? ....... and that is causing it to read 1/2 of the actual airflow....??

If you were at WOT, the TPS is way out of whack.......it should be close to 4.5 volts at WOT......your's never got over 3.5 volts....

edit - after looking at the 006 file.... I assume you didn't actually go WOT on the 004 file..... and did go WOT on the 006 file....

It apears if you only look at the portion where you get on it a little.... things look decent.......as it was on the 006 file...... albeit I don't ever make tuning decisions based on non WOT data.....as would be my recommendation to you... I mainly look at high gear only (3rd).... WOT data.....



(006) file - This time the TPS went to 4.58 volts. It still had the same issue with the 02 milivolts not even showing up until you mash on it......

As far as only the portion you are mashing on it.... this file looks pretty good IMHO..... TPS good.....pulse width OK....... 02 milivolts in the .730's.......boost at 20 psi........no knock....... nothing stands out as potential issue to me...... other than the .000 milivolts on the 02's before you mash on it.

Easy explanation why his NB O2 isn't showing any activity during a lot of the time, especially obvious in 006, If you graph his WB and NB at the same time. You can see that he is running extremely lean during cruise

FRom zero to 8.6 seconds, NB out put is normal, as is WB at about 14.6.

Then the WB goes to into the 16's from time 8.6 to 12.7.
Then the WB goes up into the high 17's from 12.7 to 24.1 where he is light on the gas pedal.

NB's cant read much of anything that lean.

thanks much for the replys...I do have the lean cruise on and I think it leans even farther than normal because of the E85. As for some of the readings not being WOT it's because I just left my laptop on to record when I got on it...tps=3.5+ or something like that, so it just recorded anytime I started to get on it. Back to the lean cruise...It shouldn't matter how lean it goes with no load...right??? Well as long as it still runs good of course.

I had thought you might have a lean cruise.....it appears to be working wonderfully...... 18:1 AFR at one point..... Mine used to run about 16.5:1 on lean cruise.......although I would want it as lean as possible and still run good....like you say....
