It's out of their hands really, a lot of parts I've even ordered from other companies are delayed due to the labor disputes.

Can anyone offer an analysis of my datazap?

if its the one a few post back

looks reasnoble
bit of knock in places can see some evident arround 5000rpm
your IAM is 0.98 again indicating minor knock
AFR and fuel trims look reasonable for oft tune

you need to log knock parameters
FLKC
Knock Correction (FBKC)

instead of VVT intake vvt exhaust

to see the knock better

are you on 91 octane ??

91 octane, stage 2 UEL 91 2.063 tune, OFH and inlet/kn filter.

I will do another log with the knock parameters youre asking for.

Thanks for taking the time to look

talk to @JB86'd he is on 91 with same tune I think and should be able to give you Base_timing_B and IAT temp compensation tweaks to sort that knock out on 91

very cool. I also just made another log, a short one, but it has at least 2 pulls in it and I turned on the data channels you mentioned. Will post tomorrow.

Lol our 91 octane sucks butthole.

Now that my IAM is pretty steady at 1, I'm going to be switching to E85 pretty soon for the long term

nope your 91 is better than our 98 ron fuel iam 0.5 stock and our south african mates only have 95 ron stock cars on stock tune iam=0.2 to 0.3

but we do have pumpe85 that guaranteed e85

you guys got it made and its cheap petrol to

I beg to differ lol on 91 you can seem your IAM drop to .50 in some cases I've seen it go below that! I even have the datalogs to prove it. The 91 tune is quite a bit too aggressive, if you don't pull timing you're pretty much gonna be running around half timing.

The 91 tune isn't a 91 tune at all from my experience with it lol, but I remember reading in a thread that shiv says it's okay for your IAM to drop below 1, knock sensors are just doing their job.

Here is my second log with knock correction and flkc recorded... I see no knock correction but then again I don't know much about what I am looking at.

Looks like you have some knock in the 3600 to 5000 RPM range.

Reflash your tune (this resets IAM to 1) and start logging and go for a cruise, let the ECU learn a bit then maybe do some WOT pulls & you'll be able to see where the ECU begins to pull timing but from your current log its 3600 to 5000 RPM however there could be more knock elsewhere when your IAM is starting at 1.

Yeah you have some FLKC even with your IAM at .63, which means you're going to need to pull timing, maybe find better gas if possible. What fuel are you running?

fucking 76 "top tier" 91. I hate this state sometimes.

Same. I would try Shell if you have a station nearby, I've had good luck with Shell, it's more knock resistant than Chevron in my experience, don't know about 76.
