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.

I'll get new mains tomorrow because the 135s installed are the biggest I have. Do you think 145s are big enough? Regarding the air corrector jets, I have 210s installed and the biggest I see listed is 220. Is there anything besides larger air corrector jets that will bring the mains in sooner?

Is there anything besides larger air corrector jets that will bring the mains in sooner? lets work one problem at a time....what is your wide open throttle readings now? find a long gradual incline and do some 3rd and 4th gear WOT pulls. are your plugs new? valves adjusted? carbs synced? air filters clean? do you run premium fuel? i forgot........one very important thing. you need to disable you accelerator pump squirters. i just pull the little cotter pin thing and let the arm fall. when your done with the jetting we will hook them back up. you may find you only need a little squirt from them. but you have to disable them cuz they will throw of your readings. |
