Help trying to pass emissions test with turbo 6.0 using plx wideband not 02's On a Open loop Speed density Tune. Dono How evap was from factory or why its showing trouble. Need a direction to start.

 

I have this same problem

 

EFI Live has a setting that will allow the Evap test to run in open loop. I looked through a HPT tune i have and I could not find the setting, maybe some one of yall can find it.

 

I found them.. I got evap gone but still working on the o2s. I'll post what I did tonight. I'm on my phone ATM.

 

I think if the evap is cleared you will pass.....you are not allowed more that two readiness failures according to my inspector.

 

i was pondering this myself but if all codes are off , they will pass readiness tests .

my question is for sd tuned , you have to keep your maf code at least the p0101 for your engine to go into sd settings . is there a way to have this not show up and still run so when they check dtc's it isnt there?

 

"For off road use only .
Found this googling around : "P0131-P0167 - Oxygen sensors P0400-P0430 - EGR, AIR, and catalysts P1133-P1156 - Oxygen sensors P1404-P1416 - EGR and AIR systems P1441-P1443 - Evaporative purge Set to "not reported" should show you what you want to see, at least with regards to the tests. Leave the MIL indicator enabled for all " , not my work and have to state again "OFF ROAD USE ONLY" ."

Follow this and it will clear all the system checks I was trying to clear.
I dono about that one either maybe someone else can help us. I will post it in my efi live support thread and see if I can get an answer for us.

 

If you set P0101 to "not report" the pcm will not go into SD mode, and if the MAF is gone, the pcm will flood the engine with fuel.

 

Correct.. I tried it.

 

I've always had to switch back to a mass air N/A tune for emissions.
