Logs - Fuel OK?

Hi all,

I've recently flashed Stage 2 93 with supporting mods. Would someone please be able to cast their eye over them?

I'm in Australia and from what I've heard we don't have the best octane out there. Whilst I've never had any issues, I wonder if the logs indicate that I should be running Stage 2 91 instead to be a bit safer?

Thanks in advance!

I'd say you're good on 93, timing was pretty tight and advancing all the way up. You had knock up top on one run but there was no corrections from it.

Thanks Mojo!!

Here's another log from the same night but with a little bit of acceleration into 4th too.

Should I be concerned by the knock appearing on 2/3 of the logs?

Try the 91 map and see if it disappears, the power difference between the two isn't substantial. Make a support ticket with PTF and see what they say.
