I have to get larger chokes and re-jet my 1911cc/dual IDF40s and was thinking of installing a wideband air-fuel gauge to help with tuning. I've looked at a few digital gauges for around $200 that include the gauge, O2 sensor, bung, wiring, etc. Wondering if you guys have any sourcing recommendations and install tips. It looks simple from what I've read. Thanks for any help you can provide.

Here's what I have:
1911 cc with 8.6:1 compression Webcam #86 with Bursch exhaust ACN SVDA with vacuum connected below throttle plates. Timing set at 27 BTDC at 3500 rpm (vacuum disconnected) IDF40s with 32mm chokes, 135M, F11, 210A, 50I AF at idle is 12.5. When I accelerate easy in 1st gear it goes way lean...like 16-19+ and hesitates. Pretty much does the same in all gears, at steady state and 2500 rpm AF is 13.5 but giving a little throttle the AF jumps up to 16+ and it hesitates. Same at 3500 rpm. At 4500 rpm steady state the AF is 15.5. I will drive it more over the next couple days and take better notes. Sorry for not having better data but I had to rush home to meet a realtor...3 hours later my head hurts and I'm trying to remember AF data (IMG:style_emoticons/default/blink.gif) . |
