TwIzTeD_3kGt brought it up to me on 3si. My Evoscan log looks like it takes me 10 seconds to go 2k-3k in third. What settings to I have to change?

Might as well post the log and ask for tuning help here as well.
Need to adjust fuel trims on front(O2 sensor?) and see why it seems to hit fuel cut with a walbro 255 hotwired(though the pump doesn't whine anymore, but I can hear it run... Bad pump?).

Greg, would you suggest I just do more reading on the evom forums?

Your narrowband O2 sensors don't look to be anywhere near reading correctly. Most of the time they are dead, even when your wideband is showing rich. Your low fuel trims are way off (+12.5% on the front, -4% on the rear). Unplug the front O2 while it is running/logging and see if the correct input dies in the log. Maybe they are reversed somehow?

Are there any codes stored on the ECU? O2 sensor codes?

No wideband. Can't figure out how to get Evoscan 2.6 to pull CELs. I know in the past I had a front o2 code come and go(non chrome ecu) so I could check with palm. Front o2 is disabled in chrome

Why is the front O2 sensor disabled? unless you are using a JDM setup and only have 1 O2 sensor you should have both enabled.

edit: as far as pulling the CEL code, its an OBD2 ECU so hit up your local parts store and have them scan it. unless its some crazy Mitsu specific code it should tell you what the code number is (might still have to look it up though so post the code number here).

From my recent research it seems that you have to go into the Evoscan Program Files, and delete the "OP20PT32.DLL" due to some random conflicting codes or whatever the issue may be.

Front o2 disabled cuz I saw front trims at 12.5% and it not cycling.

the front trims being at 12.5% and the O2 sensor not cycling means there is a problem that needs to be fixed. turning off the O2 sensor doesnt fix the problem.

What sort of problem? I thought the sensor was bad, hence why I disabled it. Fpr overrun? Bad injectors?

Probably means your O2 inputs are swapped on your adapter harness...

could also have a cracked front manifold which would allow fresh air into the exhaust stream at idle making the PCM think that the front bank is running lean, thus adding fuel. it could also have a bad injector which is actually causing one of the cylinders in the front bank to run lean, and the PCM adds fuel to correct for it.
