Please help read my logs

huzidada · 08-06-2010, 04:47 PM

Hi. I have a 2002 JDM STI.
Rebuilt motor( detonation caused piston damage), but besides all bolt on mods, car is quite stock.
Stock IHI VF30 turbo, boosting .95-1.0 bar on 95RON(useless fuel).
Injen intake, full exhaust back to front.

Was wondering if anyone could have a look at my data logs please. I would like to understand whats going please.
I live in Swaziland, Africa, so no tuner here to explain to me. Tuner is in South Africa, so a bit far from me. Car is ECUTEK'd. If the wastegate duty cycle is low, its because I use a boot controller, and this is the low boost setting for the "useless" fuel. Used ECUEXPLOREr

3rd gear log

1st-4th gear

This is screenshot from Learnview but I dont think its working properly. The IAM value is cool though, it can read fault codes and reset ecu'

from what i see 3rd gear log.
your only building 13psi of boost...right on par with 0.95 bar.
0.75 lamda..11.0 afr
but you're only at wot for about 1.5 seconds..

jaxscuby is saying you haven't given us complete data to look at.

go out and take 3 datalogs of 3rd gear, 2000 - 7000 rpm, and log these variables:
rpm
boost pressure
turbo dynamics
maf voltage
maf airflow
wideband afr
calculated load
injector duty cycle
throttle position
fbkc (feedback knock correction)
flkc (knock learning)

ask a question. what are you trying to learn from your datalogs? the list i gave you will inform you about open loop (wide open throttle) operation, but not much else.

Thanks guys...

Uh Im using ECUExplore and some of those parameters are not there(maybe they are and are called something else???)
