Im running a modified OTTP tune given to me here on the forum. Runs great.
I played a lil with it and added a degree of timing. Logged for knock and saw none. So that puts me at 19.
Should I push it till I see knock (and back off) or leave it as is. Car has basic heat mods so no meth (hopefully in the future).
Some LSJ guys are running 20-21 without meth on 93?
Heres a log. Input?
What are your mods? M62 or TVS?

M62 2.8 60s zzp catted mid length/dp combo, stock catback, zzp 3 inch cai, zzp s2 h/e, zzp 1.0 pcm with ottp hpt tune basic power mods anyway. oh and 2 heat ranger colder plugs
should be the relevant mods.
With the proper cooling mods and phenolic spacers I've been able to squeeze as much as 21* up top on 93 octane. It's a bit aggressive but back-to-back runs testing the IAT2's and looking for KR will ensure it's safe.
I've been doing a lot with mid-range timing on the LSJ's and I've had noticebale improvements on driveablility and throttle response. A nice smooth ramp with some additional timing has given a lot towards the feel and out of the hole/out of corner accelleration.
Basic stuff but I thought I'd share
