funny smell after new cam i just put in my tr 230 and started it up to make sure everything was okay before i put the stall in and get tuning, ive started it severel times and it smells strong of gas i guess, anyone elses do this, im not for sure its gas, the smell comes through the exhaust?? any thoughts?
Re: funny smell after new cam Mine ran rich till I tuned it with EDIT
From what I understand the longer duration Cam keeps both valves open longer at the same time. Allowing raw gas to pass through the exhaust.

Re: funny smell after new cam Yep, that's what's happening, you're not alone. If you look around you will see there have been several threads on this lately. I fixed mine my scaling down the VE and the Open Loop mixture. Are you going to be tuning it yourself?

Re: funny smell after new cam When somebody mentions scaling down the VE, are they referring to the crank VE or main VE tables (or both)?

Re: funny smell after new cam
It would just be the Main VE Below 1200
But I left my alone, and raised my IAC's.

My gasket's/head bolts are being delivered today, so I'll be able to finish up my 5.3L Patriot S2 Heads / TR 224 cam install this weekend. After that...it'll be tuning, tuning and more tuning!!!

Re: funny smell after new cam
yump..mine's doing it too. Just installed the TR224 and it's pretty bad. It's called cam surge and will happen until your car is tuned. It's very noticeable since you have a stock T/C (like me). Higher stall T/C wouldn't jerk the car that hard, but the engine would still surge up and down.
thanks for the info, i will be tuning it some time very soon!!!
