Which wideband?

[Telco]

Hi guys, back for more help. I'm putting a new engine in the Silverado, and since I'll have a complete exhaust (current engine has a busted exhaust bolt in the head, too deep to get at without pulling the head, too expensive to fix when a new engine was coming) I plan to use a wideband to do the VE table and tune the truck properly. I was hoping to see a sticky with a rundown of widebands compatible with EFI. What I did find was a lot of stuff that looked like I'd be having to build cables and stuff to install a wideband.

So the short question is, which wideband do I need to buy to do a proper VE table on my truck that would also be a plug and play setup with no cable making needed? Thanks.

Definitely get a wideband controller(s) that is supported by the FlashScan V2 serial interface. I think you'll find that the Innovate LC-1 is by far the most used sensor (probably due in the main to cost). I have two of them on my car.

Other honorable mentions would be the Tech Edge products, FJO Racing or if money is n object the ECM products. Here is a listing of supported serial wideband controllers (http://www.efilive.com/index.php?opt...138&Itemid=143).

Good deal, thanks. Looks like the Innovate LC1 is the most supported here then. All I need is the LC1 wiring harness and the sensor, correct? I don't need any other interfaces, and the wiring harness will plug right into the EFI Live box, correct? Or is there anything else I'd need? This is what I'm looking at getting.

Yes, that interfaces to FSV2 using a null-modem serial cable, available from TAQuickness.

Sorry it took so long to get back to you. This is the first time I've had a chance to sit down and think about what you've said. Wasn't able to find out anything on the cable from looking around until I found the link about taquickness not being available and found this diagram.



If this is all I need to do, no problem. I can slap a cable together no problem. Ording the LC1 now.

Telco,

See post #3 here: showthread.php?9340-serial-port-cable-that-goes-to-v2

Or, you can fab up your own cable.

I have researched this same question over the last couple weeks, and folks that I have talked to lately are really high on the NGK AFX product for a couple of small reasons: ECM was involved in the product design (Engine Control Mgmt Inc, they are the world's authority on professional OEM exhaust gas analyzer equipment), and it uses the NTK sensor instead of the Bosch sensor (the NTK sensor is known to be far more accurate at low lambdas than the Bosch sensor, it is the sensor used in high-$$$ OEM exhaust gas test equipment), and it can be calibrated. So, the NGK AFX uses a real professional sensor, and has control circuitry designed by the best in the business. When I opened the box I was VERY impressed with the build/construction, the loom & terminations are very well made and generous, you get an exhaust bung and O2 sensor plug in the box as well so you can remove the O2 sensor and plug the bung, thus saving wear/tear on your sensor! The included instructions are VERY good, and downloadable on the web too. The LEDs are huge, you can read the wideband easily from across the street. And for $269 direct from NGK you get a lot of value in the box, it's twice as nice as the PLX wideband I used to run. Only 'con' is that there is no serial output, for me that's not a biggie. I like this product and highly recommend giving it a look if you are in the market for a WB02.

PS - One other thing that impressed me, I had to shorten the harness to install it in a '04 Silverado, and the actual wire they used in the harness is the best stuff I have soldered in a long, long time. It's a little thing, but to me signals a huge committment to quality. FWIW.

Thanks Mr P, but I've already got an Innovate LC1 sitting in the back of the truck now. I decided to use the one recommended by the majority here.

Is there any way to get NGK to add a serial comms port to their AFX...?
