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.

Will disconnect squirters and take more readings. With the main stacks removed, how will I know when the mains kick in? Also, do you think it's an issue of only 1/2" gap between the velocity stack and air filter? That's the ways it's always been but it doesn't seem right. Do most setups run the velocity stacks?

Do most setups run the velocity stacks? the 1/2 inch may or may not be a problem....i run velocity stacks but it seems like i have more room than that. its raining right now or i would run out and check. post up some pictures of your setup. you could find out pretty easy while your out testing......make a pass with your tops on than make another pass with them off. and see if things changed. and report your findings. you will know right away when your mains tip in.....the car will fall flat on its face. this step will teach you how to feel the progressin circuit. it is very important. soon you will be a weber master. thats why we are starting from square one. idles........disable you squirters, remove your main stacks, reset your mixture screws (lean drop) then drive it around. you will find out how the idle circuit works and when it stops working. and that will depend on your throttle position and vacuum. the farther you open the throttle the higher the vacuum, your idles will gradually become overwhelmed (leaner and leaner) youll see it on the gauge. thats when your mains will take over. but not yours cuz your mains will be on your work bench (IMG:style_emoticons/default/biggrin.gif) the idle and progressive circuit are handled by the same jet in the IDF carb. |
