Need help on a major tuning problem with fuel adjustment

[redgst95]

Follow these instruction for the PLXM300 Rear-02 location. If you want to simulate your narrowband you can follow the PLX link dirrected in the notes. I strongly suggest connecting the front 02 sensor for tuning your LTFT's. I used a wideband simulation for 9 months with poor MPG & LTFT tunning results. It's just to far down the exhaust stream for accurate LTFT tuning.

For tuning your LTFT use this

Any other questions. Ask..

Thank you for the links scottsee it answered alot of my questions!...... How accurate is the dsmlink afr compared to the wideband sensor located in the rear o2 bung?I have a good size exhaust leak right before the wideband sensor would that cause pretty inaccurate readings on the wideband?

The estimated afr is not something to rely on but it is supposed to be a close match to the wideband if your air metering is correct. It does so on my car.

A leak will definitely cause inaccurate readings.

Who said we won't help him anymore?

Im willing to help but he needs to at least learn the basics or do research before modding. With a setup like that, he should know that a car needs an o2 sensor

EVERY thread i've started where i mentioned i dont have link registered in my name its like people turn the other cheek and thats the end of the discussion.

Oh well

All you have to do is pop open the ecu and call ECMtuning or e-mail them and they will re-redgister it in your name..
