Ka-t dies on decel

Post by blarousse »

So my afr seems pretty good most of the time, but when I'm slowing down or coming to a stop the car goes rich and dies. I have t28/550cc/z32 on an rs enthalpy tune. Any Info on what I should be looking into is appreciated.

No. I was thinking about it, I just have to figure out how and where to run the hose to on the intake. And I have to buy the kit. I was kinda hoping to be able to keep it vented to atmosphere because I love the sound. I've also noticed that the cooler it is outside the richer my car runs

It sounds as if you need to check your tune.

Are you blow through or blow by?

This is a very likely reason, unless your Enthalpy tune can somehow account for the sudden loss in air intake...which I doubt.

I've experienced an issue like this before. how close to the turbo is your MAF? If it's too close your maf will experience turbulent airflow causing the readings to the ECU to be innacurate.

Put your maf at the end of a intake pipe with a curve in it. Put your idle at 900 by using the screw on the tby. Worked for me.
