Hey y'all,

I'll upload some logs but it appears im getting some ignition correction around full throttle and 3000-3500rpm. I'm assuming it's a fouled spark plug so I'll pull those today, but if anyone has any suggestions let me know.

https://chadneu.com/cobb-log.csv is the latest log. You'll see around lines 200 that I get a good amount of correction. This manifests, while driving, as a slight bog. It quickly recovers and doesn't happen above 4000rpm.

Ill update after I do a plug swap. I'm also upgrading my dizzy tune so that might fix it as well.

Here are my plugs. 1-4, left to right. New plugs are in, gonna go do some pulls with logs enabled. Hopefully this fixes it.

I find it interesting that 3 and 4 seem to be leaking some oil or they're getting pretty hot. That discoloration aint great. My car never overheats or show signs of being too hot. I have a trip pass rad in there.

Aaaand new plugs fixed it. I did a bunch of 4th gear 2000 to redishline pulls so I'll upload the logs for anyone who wants to dig around em.

edit: https://log.tunezilla.com/s/mGVfx6yD https://log.tunezilla.com/s/6En3d87y https://log.tunezilla.com/s/WtucRZIW No bogging or anything anymore, but still some adjustment. I figure that's normal? Input from others?

Oh, also, when I pulled the old plugs they were all gapped to around .030 which is a bit too large. That could have been doing it. All the new plugs are gapped to about .026". Now I'm just waiting on Jason over at Dizzy to send me the v3 tune.
