Default data logs, my03 wrx

hey all - i picked up the tactrix openport 1.2 obdII cable during the week and logged a couple of runs this morning using ecuexplorer. installed a new exhaust system last saturday and wanted to get an idea of how was running.

not tuned at the moment (although ecu will happen asap now as a result of these logs), and didnt reset ecu after the install.

was just hoping for feedback on the attached run, shows some interesting results. first gear and second gear pull around 50% throttle.

car and mods as follows:
MY03 WRX, BPM GT Split Dump exhaust sys w/ metal cat, intercooler hoses, panel filter, shortshift.

this log shows a lot of knock correction occuring under boost, and at several points the inj duty cycle hits 98%! i spose the main question behind the post is to determine if the injectors are actually maxed out or if this reading could be high as a result of a weak fuel pump or similar.

are stock my03 inj 380cc?

Use absolute pressure.. so you can account for atmos conditions.

Should do WOT (100% throttle) runs in 4th from a very low speed.

That nice big 20 AFR hill in the middle is not much to worry about but would be better to check it with a wideband.. its more likely to be due to the fact that you have taken your foot off throttle and the injectors pulse has been switched off.

Although i would not use the stock AFR sensor for basing any REAL judgements on.. definately use a wideband.

Also using Fuel Sensor #1 Learning would be good too.

Ahh yes the knock correction.. if the knock correction is heading south (into negative numbers) then its a cause for concern.. not too bad overall however.

-1 or -2 KC on cruise is pretty normal.
