ok, hopefully you guys will be willing to help a newbie with what is probably a stupid question.

i am getting ready to burn my first chip

the car is a 90 TBI 5spd camaro.

i got winaldl working and have been doing lots of datalogging for about a week here.

the weather has been pretty consistant when i did the runs.

here is my question.

how do i figure out if the data is good to use or not?
sorry i dont' have the files to upload, because i am not at that computer right now, i will upload them when i get home from work.

but what kind of range do i want in the std. dev to know if it is a good reading or not? and how many samples do i need per cell?

i read the tech article, that said to do this on a level stretch in a high gear (i have been trying in 4th , but to get to 3200 RPM in 4th is really breaking the law with 3.08 gears) would doing my runs in 3rd gear still give me acurate data? i am really just having a hard time finding info on what is an acceptable tollorance for the data, is a std dev. of 3 or 4 ok, or do i want to shoot for a dev. of <1 ? and do i need at least 10 samples per cell, or is 5 ok to use?

also, when you guys do this, do you just use the correction factor table from the BLM data, or do you actualy do the math on this data some other way? i have seen an equation for BLM-(INT/4)/128 or something along those lines, is that the same equation that the correction factor uses, or should i be doing something diffrently.

i am sure i will have a ton more questions for you guys, but i think that should get me started.

THANKS ALOT
John.
