no its not garbage left over.

I did it so those values are populated with sane values rather than being blank. 8d is vehicle speed == vsbar. I have it logging for vsbart_rt which is reverse calculated vehicle speed from the oss on newer ecus. Since the older ecus dont have it I have it showing the vss mph so anything that relies on it such as histograms or my calculate nvbase is correct and still populates.

The payload list shows you the order the payloads are being polled. http://efidynotuning.com/payloads.htm

Your mising the top byte 1f1f for the variable speed fan which a1c doesnt have.

d6 is the atmr1 timer
396 is ipsibr
b6 is ect
b7 is act
etc...

11a is the throttle position sensor voltage which other than iego and iegr is the only useable ad channel to read. On newer maf ecus imaf would be another. The other ad channels are only useful for diagnostics and serve no purpose to log for tuning.

raw ad values usually get passed through rolling average filters then passed through transfer functions to come up with a useable value such as the ect and act. Logging their raw voltage wont give you any useable data for tuning.

That should clear it up for you and make it easy to understand. If not lmk and Ill break it down.

nah your good.

You might as well fill out and submit a vehicle info sheet just to verify you don't have anything that would cause any issues. I'm going to go ahead and put together a base tune for you so you can verify the datalogging for me tomorrow.

Yep that is a bone stock tune alright.

nvm its PYM SAD 806x I have 1.0.0.3 dated 2020-06-05

Whats the latest and greatest version disassembler ??

Who's was resolving 0x100 offset odd word shortcuts?

yea I thought of you when this popped up. Theres been a couple others expressing interest as well so figured id toss it on my to do list. I already have most of this strat disassembled with my own short hand xdf for the trucks I tune I just need to make a user friendly xdf for yall and restructure the logging for the latest adx.

nope thats how it functions stock. My marauder goes in to cat protect everytime I get on the interstate at least once. If I didnt have a way to log or a wideband you would never know it as most people are completely unaware.

You can raise the commanded lambda if you want or disable it if you dont have cats otherwise leave it be as it helps the cats survive your driving habits.

yeah no problem

go ahead and read out your stock tune and post it here so i can copy over your pats code and vin

Nah its not neccessary. Give me a couple days to crunch it out and I'll post it along with a base tune.

If your lightning is modified youll need to become a premium member otherwise if its all stock or basically stock I can post an xdf for you but hadnt finished the logging since no premium member has used it yet.
