I need a simple way to monitor my A/F or simpler whether I am "smoking" on my 6.2 diesel. I believe I need to turn down the ip a bit (never would smoke before upgrade) but even with that turning 500-1200rpms at times will mean I am riding the edge for smoke. I am geared so the motor outputs just enough to keep it moving on the flat, no more no less this drives like an old 3 on the tree except I have two overdrives after that.

I am wondering what the cheapest way to monitor this would be?

I am thinking one of those $9.99 see in the dark security camera jobbers aimed at the exhaust might work but I haven't seen any good deals in over a year.

Otherwise I may need to install a wideband to keep the A/F around 16:1 or higher.

Its way too easy to give it too much fuel so I need something to get me into proper throttle and shifting points. But the power boost going to MT has been quite amazing.

And I have sucessfully driven 600rpm @ 30mph without smoke, just a fethers touch is all, doesn't help the throttle is sloppy and hard to accurately control though.

Any ideas?
