Guys/gals,
I've been trying to get my car to start up properly in very cold weather with cat warmup delete. I have been thusfar unsuccessful. Attached is my current tune with cat warmup enabled with cams in the stock configuration. I will pay the first person to get my car to start and idle properly with the cat warmup deleted $50.00 via Paypal or Venmo.
The issues I'm having are when the car starts up and is very cold, instead of idling where I've set it, it will bog out and stall. Sometimes, it will bog out then correct itself several times before it settles and idles ok. I have not been able to correct this with any adjustments to Optimum Spark, Optimum Torque, etc.
The first attachment is with cat warmup enabled.
The second attachment is my attempt and disabling it.
