Would anybody mind viewing a 15 min segment of my Z06 EFILive V6 file and tell me if they think my engine is OK. It seems to me the O2 sensors are going wacky. They are all over the place and the left and right LTFTs differ significantly.

Thanks,
John

i'll take a look at it. email me the file at layzi3@juno.com

in closed loop they should be all over the place..

only when you're at open loop do you want them to be somewhat stable or linear in action.

JRP...you've got mail!

sorry, spelt my own damn email address wrong its layzie3@juno.com forgot the E in the first one. send it again if you can.

I was wondering why my mail came back.

Anyway, resent the file.

ok, looked over it. LTFT's look okay, there in the negative and just slighly postitve at times at .08 or so. you spark is all over the place though ranging from 40* to 4.4* . and is it just me or is your o2 voltage not on there . im more versed in V5 then V6 and i couldnt find the o2 PID on V6.

and wheres' the KR read out?

I can send the PID file. Would that help?

im just saying i thought the o2 and KR was a standard PID like it is on v5. i just couldnt find it on v6, i didnt mess with it all that indepth yet though. but from what i say its all good minus the low spark your getting at time dont know if there's KR present though since i didnt have the PID setup. but if your in closed loop then should look like a wave going up and down.

ok, got it . your only getting KR in one spot and that aint too bad. i dont remember what cell 21 is but your reading are way low, 0 o2 voltage and 4-10* of spark.

Thanks JRP. I'm going to log more data once the weather gets better. I want to get a good sampling from different RPM ranges under a constant load as well as some WOT .

Since I'm new to this, all the help is appreciated. BTW, there are some great guys on the EFILive forum as well!

I hope that's some dark import beer !

Timing from 0 to 45 degrees is possible, remember, these aren't springs and weights anymore!

BTW, in v5 and V6 there is a default PID file, but it's best to log only what PID's you need to keep frame rate as high as possible.

Do you have a link for the EFILive forum? Just started trying to figure this stuff all out.
THANKS!!
