Datalogs after some mods
Hello,
Im new to the whole datalogging thing but i did set up a zeitronix zt-2 and
zt-3 with NDash screen before i did any mods. I added EC heat exchanger, new Bosch 010 pump, colder NGK plugs, EC mid length headers, Fabberge mids/x-pipe with 200 cell cats, EC box tune.
These are back to back short 3rd gear pulls. From what I know and can tell all seems ok from what ive researched but I know a lot of you have good amount of experience looking at these. One thing Id like to know is on the second log you can see the timing doing these little "waves". is this a small amount of knock retard and is it normal? it doesnt seem like its pulling timing way back so i dont know. This is also for only 91 octane.

Iats look good, afr looks good, timing is steady on the first and rising compared to second pull.
You need to do a longer pull to see where you are at 6k rpm min
What is the amb temps there since you are starting at ~70* iats?
