Well I decided to do my first datalog today since it was about 48 deg out. I did a 3rd gear pull to redline.
From what I can see there are no knock counts, but the knock threshhold is all over the place. If someone can look at my datalog I would be greatful. I'm a noob and am still learning what to look for. This can't be normal can it? I'm using the K20A2 Type-S cai dyno tuned cal from the Kmanager to start out with.
When I looked under errors I notice batt voltage was low until the rpm's climbed.
There was also a spike in a/f at low rpm at one point.

wow , mega lean man. there is no type s stock CAI cal. there is a k20a2 stock tuned , and k20a2 cai. be more specific.

another guy that cant do a datalog. whats with people rolling on the thottle? get the car at 2k rpm , FLOOR IT and hold it till redline. you started to throttle it at 2k , and didnt reach WOT till like 3600 , makes the datalog useless. need another one done properly.

My bad it is K20A2 dyno tuned cai.
Like I said this is my first time doing this. I thought it was 3rd gear at 3k then floor it.
Btw my tps read 100% at 3273 rpm

I hear that. I will try another run and post a datalog.
I have a dumb question. When datalogging should the car be in open loop or closed?

It'll switch to open loop automatically when your doing WOT runs so don't worry bout that.

If your tuning part throttle it needs to be switched to open loop through Kmanager.
