Can anyone HELP? Evap and catylst not ready still exist. I driven quite a few miles highway speed. mountain roads etc. I'm lost for a fix inspection time due May 1. I do have high flow cats and had a Mafia installed to complete tune. 02 sensors are turned on in the tune. Cataylst monitors heat up( verified with scanner).

When they fixed the tune did they make it go directly to open loop?

On my race tune we have the car go directly to open loop. That way it doesn't flood the chambers with massive amounts of fuel. The car (stock) is set up to start and rev the motor higher to heat the cats, thats a bad thing when your running C16 and it takes a bit of heat for it to burn properly (to begin with through the huge huffer on there and it's worse). Hence we send it straight to open loop so it doesn't go through the heating process. Give it a few minutes to warm up and she's ready to go.

If they did this then the car doesn't go through the cycle to heat the cats and it might be causing the problem. It never gets the closed loop feed that says its ready to switch to open loop. Hence it never signals the cats and evap are ready.

Sorry, I'm not a tuning geniuse....not my forte but I hope I explained my idea well enough.
