Default sd tune question

ok if i got my car tuned in sd would I still be able to pass emissions if its just visual and obd2 scan not a sniffer test? Like would it still complete the moniters or no? Also if instead i got the p1113 and p1153 code for insuffecent switching would it still run all the monitors for the car or no?

Mine passed with a SD tune. If you set to no mil it should take care of the codes.

So your saying if it is sd tuned it will still throw the maf fail code? Also if i had the p1133 and p1153 code tuned out would it make it run in open loop or could it still go in closed loop?

The code will be there. You have to change the "DTC Processing Enablers" to non emissions, it will trigger a code but not fail the E-test when tested.

At least that's what I did, and it passed just fine.

By setting the codes to non-emission it can be read but will have no effect. If you were to check for codes with your software the MAF FAIL will show up. The OBDII scan only looks for codes that will affect emissions. By setting the MAF codes up to non-mission they will not cause a failure.
My car was scanned for OBDII codes and none came up. I even had the MAF removed for the visual and they did not catch it.
I even had mine tested with a tank full of E-85 and I passed.

All the sensor monitoring will remain intact.
