Problem with my tune, misfire on low trottle

Post by Erajk » Wed May 25, 2016 1:46 pm

Hello!

https://drive.google.com/folderview?id= ... sp=sharing

Can someone help me have a look at my tune?
The car misfires on low trottle and are running rich under WOT.

The car ran great when we tuned the car but one day after the car fuel adjust bad when cruising and running rich (AFT 10.2-10.5) WOT.

How is this possible?

Is this wrong?

Have you discussed this issue with your tuner?

I have a simliar issue like this.
My Civic Tpye-R runs rich in WOT but in cruising all good. I checked the spark and changed O2 Pri sensor. Same problem with new sparks and new O2 Pri sensor.
I will change the injectors maybe one or two are bad and leaking.

Hope it helps.
