Here's my Datalog
can someone take a look and adjust please ;)
Also how would i be able to tell if i need a new o2? This one looking ok
? k20z3
cai
s2 alpha header
catback

Re: Here's my Datalog
Ok. Understood. I'll upload the calibration also soon today.

Here you go! Please adjust if you can :D

Re: Here's my Datalog
I think you need to either calibrate your CAI so that the air flow is properly measured, or just switch to the MAP based version of the tune you have, which is "Civic-Si-Race-6-SkunkHdr"
Re: Here's my Datalog
Ok. So i tried that today. Its called "FG2/FA5, MAP based, CAI, Skunk2 header & catback". Here are 3 Datalogs that were ran from home > Stopped somewhere > Left to stop somewhere else > then home.
Thx for the quick responses & help!

Re: Here's my Datalog
It looks like the O2 sensor works OK at very low loads. At medium loads the measured AFR starts to look abnormally lean and at high loads, the measured AFR is obscenely high. There is no way your engine actually needs that much fuel, unless you have a supercharger you are unaware of. You also have fair number of knocks, although I do not know if they are detonation or false knocks. It's as if the O2 sensor is working properly, but the AFR reading is incorrect at medium and high loads. I wonder if you might have a exhaust leak where the header bolts to the head? Does anybody else know if such a leak would throw off AFR's so badly? I don't have experience trying to tune a car that's not 100% mechanically sound, or without driving it, for that matter.
Also, you never get to high cam since you don't go over 4500 RPM. Why? Is the car running that poorly? And, there are several times, when throttle is at 0%, and the engine is at idle speeds, but the RPM oscillates from 850-1400 RPM for several seconds. At first, I thought you have a vacuum leak, but then noticed it's happening when you are are in 5th or 6th gear. Have you noticed this? What are you doing?

Re: Here's my Datalog
First off thanks for your response.
Could I have a bad o2 sensor even though you think it's not that. I have a alpha header & catback. I had a honda tech put on my header. He used a mirror ro make sure gasket was good. As I was under the car helping.
Tomorrow I'll do a few pulls so it'll help more. On the o2 afr tach gauage feature. What should the reading be? 4500rpm = 14.5? And during the whole pull?
The car runs fine and pulls harder then stock cali
I've sprayed all over with carb cleaver to look for anyou vac leaks. Around injectors, lines, booster, and tb.

Re: Here's my Datalog
A typical "pull" would be (assuming you are by yourself on a deserted, straight, flat, stretch of highway with a 70mph speed zone): put the car into 3rd gear, let RPMs come down to about 2500, start the data log, roll into the throttle quickly so that you're at 100% throttle at around 3000 RPM, accelerate at full throttle until 8200 rpm or so.
But, if you are going to use the tach-AFR feature, you obviously will have no idea what RPM you are at. The tach-AFR will be 4500-4700 rpm (14.5-14.7) for light and medium loads only. Once the manifold pressure is high enough, the car goes to WOT, and tach-AFR should be 2500-2800 (12.5-12.8). I'm pretty sure there were no times during your datalogs where your measured steady-state, high-load AFR's were below 14. If it were my car, I'd want to figure that out first before driving it too hard.

Re: Here's my Datalog
So I did some maintenance so now I can get back to it. Yet still having tb learn issue. I asked vituned for a solution. I did explain as much as I could in an email. I just the the response "get a tune". Here's 2 different data logs & the cali.

Re: Here's my Datalog
Cool! I already sent you the basemap :).
