car stuck in closed loop? Hello fellas, I bought my car 67 chevelle with 95 LT1 and trans from a camaro. The guy told me its tune is in closed loop so it runs like total **** until it warms up usually 5-10 minutes. Any suggestions on who or what to use for a re-tune??. What would the adavantages of this be, im guessing the guy who built the car was an idiot?

I got the car on a trade. All I know is it was rebuilt 8k some miles ago, and was a stroked 383. As far as internals I have no clue on compression or anything??? But Its cold blooded as hell until it warms up. spits and sputters if it doesnt get a chance to warm up. once Its up to operating temp it runs great. Also It has to cranks just alittle longer than it should before it fires up.
Sounds like you need another tune. Your car can't be stuck in closed loop lol.
Open loop is when you first start your car cold. It's running off of set parameters in your computer, with no 02 feedback.
Closed loop is when everything warms up. Your 02 sensors start feeding back information (closing the loop) to the computer in order for it to make adjustments and get it running right.
Idk much about tuning, but maybe Solomon or someone will chime in here.
