Hi guys!

Hoping to do some logs this weekend - just wanting advise on what the main reading to log?
AFR
Load
TPS
KR / Knock
RPM
Fuel Pressure (to ensure over 1600psi)
Boost

Anything i am missing?

Mains just want to check boost levels, AFR knock and that fuel pressure is OK

Learning/reading up on tuning as i go as it's quite different to my Nissan tuning days for mid 90's cars...

Basically want to log to check values, will then pass onto my tuner to evaluate and help tune.

As i learn ill get more into the details adjustments, once my mods get installed

log RPM, APP, fuel pressure, KR, actual equivalence ratio, desired equivalence ratio, absolute load and wastegate duty cycle. Basically the General Performance preset. Those will tell you if you have good fuel pressure, any KR, and if you are getting the AFR and load that you are requesting.
