mike i found acess to a windows machine at my wifes work its updating now.

thanks

so i thought i was good and updated but i only have 1r03c. when i went to drag and drop ( on mac ) 1r03h it wouldnt let me do it. i went through the registration process i believe and it says updated 3 times. any info?

i need to see if someone will take a look at these logs and export them to .csv for me so i could open them in excel on mac.

im obviously having misfire issues and was going to send the logs to the dealer to prove my point.

thanks.

i logged my stft and ltft and stft bounced so much its hard to get a clear number but at idle it was between -1 and -4 both banks. same at 2000 rpms

ltfts where -5 bank 1 -1 bank 2 at 2000 and -4 for both banks at idle.

Not really the ones while driving that bother me. It's more the ones at idle where you can feel the miss and see your Rpms take a steep fall. I'm worried about cam damage or burnt o2 sensors or clogged cats all those things are pricey

no 100% on that. i have my diablo with me but truck still at dealer. so aggravated told them leave it alone i was coming to get it.

so after i began running some logs on my intune i started to notice misfire counts of any where between 2-10 on many of the cylinders at idle and upon decclerations.

well i took it to my dealer and they claim there scan took/data logger doesnt show any misfires.

so is the diablo reading wrong or ...

i ran a 10 minute log yesterday and had 2-4 counts on every cylinder. i know this is not "that bad" but i also know that months of 2-4 count misfires could end up being bad.

it seems like the last few days i get a few misfires while driving but alot more misfires in park at idle and if i raise the rpms the misfires get much more prevalent. would this be "normal"?

10 silverado 5.3

I'm reading abs throttle at 16-18 and throttle position sensor at 3-4 at idle

Should the throttle position sensor read the same as the absolute throttle position? If not how much difference should there be at say idle?

im trying my damnedest to find all info i can. post up you misfire counts when you get it logged please

ive ran logs at with both stock and 87 octane tunes, with DoD both on and off and i am still getting these low count misfires. mostly at idle and with deceleration. i get 2-4 counts of misfire on cylinders 2/4/8 every time my motor decelerates.

is this normal/common?

mike i guess my biggest question was is there ever a time when the numbers on the misfire counts are insignifcant. or should they always be 0 no matter what situation?

sorry its a 2010 silverado 5.3l 6speed

yeah all my logs are with stock tune. its very erratic tho its not a constant thing. two nights ago it was only at idle now its mainly with deceleration.

honestly i feel like its playing with me. i can tell you this tho every single time i decelerate like ...
