Can someone take a look of my datalog
 

Can someome please take a look at my datalog i want to make sure its running safe and nothing damage the engine thank you and appreciate!http://www.datazap.me/u/carewyip/log...29?log=0&data=

youve got a little bit of knock your IAM dropped when you floored it outta nowhere. Log RPM next time. I'd say decrease your timing there a degree or two nothing major. good logs fuel trims look decent.

What fuel are you using? Did u end up using ultra 94?
Your IAM dropped to .88 then back to .9. If I'm not mistaken it should stay at 1. Flkc hit 2.9.

Some one more knowledge might crime in but if you are running 91 you might want to consider 93 or ultra 94

Im running 93 esso i dont run 91 unless theres no 93 or 94 available

Yea, you've got some knock up high. Your engine is probably safe but you're losing power. I'd try different gas (Shell, etc.) -- go to a place that gets lots of customers so their gas is fresh. If it doesn't go away with different gas, you can tune it out.

Log RPM next time. Remove KC Learned if you're out of logging parameters.

That's correct IAM should for the most part always be at 1 unless theres bad quality fuels

this is another log i did today can someone take a look and let me know? im using stage1 91oct tune with 93oct gas thanks!

my IAM dropped to 0.36 for a second twice what can cause that??

answers will be no different for the new logs.

Faulty readings....

this one looks better now?
http://www.datazap.me/u/carewyip/log...data=1-8-11-12

Could do with taking out some timing over 5k or maybe make it a little richer.....

Here's a good view

is taking out timing recommended due to the 3.5 flkc reading? (from log above)

i ask because i am still trying learn what the readings mean in relation to my tune (latest link below)

http://www.datazap.me/u/n8brz/log-14...=0&data=1-5-13

also @ the 11.3 afr reading, is running too rich or too lean? thanks

that last log, commanded vs actual AFR... thats WAYYYY off.

commanded 12:1
actual 11.25:1

yet lt and st fuel trims are at 0... that makes ZERO sense.

How many KM are on the tune?

At least he is on the richer side :iono:

I HAD ABOUT 100KM ON THE TUNE

i dont plan to get it tune until i get the header but ill be taking it to the track want to make sure that im not damaging anything haha

1000km is more than enough for the car to 'learn' the new tune. I haven't had a chance to look through your logs, but if your IAM is <1.0 on the street, it more than likely will drop further on the track as your Oil/Coolant Temps rise. You could always give PC94 a shot. I had good luck using that when I was on the Stg.1 93 tune.

How does that make no sense?

sorry its 100 km not 1000 km lol

apologies if I created confusion concerning who's log that reply was towards. this thread seems to be a little more lower level conversation than the sticky I originally posted that in.

still trying to learn which values are critical for a healthy engine. if the KM question was to me, i had to of put much more than 200 miles on since this reflash. prior to that was another 93 tune that was too agressive so the relearn of ecu from switching fuels isnt a possibility.

couloured link below on ECU logging might help

If ltft is low then that usually means the closed loop portion of maf scale is good ie kind of the lower rpm and light throttle portion, section below 3v maf.

if the commanded and actual afr follow each other well in wide open throttle areas means open loop area of maf scale is good ie sextion over 3v maf


in this case it appears the closed loop is ok but the open loop section of maf scale is not correct hence his ltft is low but car runs rich during wide open throttle runs


11.2 is the rich limit of standard 02 sensor scaling so it might be even richer.

fix would be to reduce the values in the open loop area af maf scale be the percent difference in the afr and commanded afr in this case about 8%. Their is a nice maf scaling tool that will do the work for you.

I have no idea how to do it would you able to help a noobie out? Haha
