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.

With the squirters disconnected I got basically the same AF readings. WOT in 4th gear AF is 11.0 at 2500, 11.8-12.2 at 3500, 12-12.5 from 4500 to redline. Except for more hesitation it drove the same as far as I could tell. I'm tempted to try with velocity stacks removed to see if that makes a difference. Thoughts? Thanks.

Thanks. dont wory about your off idle hesitation right now. we'll fix that after your jetting is done. that will be solved when you recconnect your squirters. |
