Air/Fuel Numbers
I need to find out air/fuel numbers, so I wonder about following:
1) Which ones I am interested in: before air/fuel mixture enters engine, ones from exhaust, or both? What are pros and cons of each method?
2) Ones from exhaust I can read out through probe or using wideband sensor installed in exhaust. How I can read out ones before engine? Are there any ports on a truck that allow for hooking up of hardware/software that would read out these in real time?
Thanks in advance!

Your air fuel mixture can be measured at the exhaust. This is the standard way it is measured. Find a local shop that has a Superflo brand chasis dyno. The superflow will give you all the info you need. Just purchased a Superflow Dyno for bikes. Awesome machine.

Tony got it right...
With an abundance of modifications that change your air/fuel ratio such as intake and pulleys, you will need to increase the fuel pressure with a chip so you don't run lean. (This will really screw up your engine) If you have just an intake or 2# pulley...you really don't need to mess with anything. But if you go more extreme like 6# than it is HIGHLY recommended you change the fuel with a chip. (not the potato kind) So get a gauge and the sensor goes in the exhaust.

Dyno of my stock was done on DynoJet. What would be pros/cons of Superflo vs Dynojet?
Thanks again and in advance!

Zoran, a standard Dyno Jet machine does not have the software or hardware that can read and measure air/fuel mixture along with several other inportant readings. Dyno Jets are a great toy,if you just want to see how much horsepower you have, but if you want to start designing parts and or fine tuning, you need something that can give you more data. Superflow is a name brand of Dynos. For more info on the Superflow, go to www.superflow.com. Their web site lists all the locations by state. The read out on a superflow is on a computer screen, you can print the info out also. A typical dyno report on a Dyno Jet brand is 1-2 pages. The normal on a Superflow is well over 15 pages, even more depending on how many different measuring devices you have hooked up. They even have a hook up that measures CFM coming into you intake. SWEET. You can even map fuel injection systems with this thing.

Thats the only way to go! You can simulate countless conditions on a Eddy- Current. You can simulate your exact driving conditions with that option. That system in its simplest terms, applies resistance to your unit. It also will control your exceleration by any measurement, ie time, mph, distance. If your having problems, an Eddy-Current equipted Superflow is what you need. I would bet that all of them in CA are equipted with that.

Zoran, call John Seamen of Superflow, his cell is 719 440-2348, tell him you were talking with Tony (one of the guys he sold a cycle Dyn to Saturday in Indy), and you want some info on how his product will be able to help you. Im sure he will be more than happy to help and answer all you questions.
Good luck
