steve260z Posted June 2, 2013 Share Posted June 2, 2013 Got the idle around 900. I ordered another return arm and spring from Pierce Manifolds on Tuesday. They were supposed to ship USPS 3 day. Still not here but been tweaking the carbs. The plugs used to look rich. Made a 15 mile run. Look much better now. Maybe lean??? Quote Link to comment Share on other sites More sharing options...
T-Bone028 Posted June 2, 2013 Author Share Posted June 2, 2013 I would say those plugs look pretty good to me, I believe they should be a light gray to tan color when running right. And I know its easy for me to tell you how to spend your money, but...invest in a wideband! $150 to take the guess-work out is worth it to me. What is your jetting?

steve260z Posted June 3, 2013 Share Posted June 3, 2013 Which wideband would you suggest? I'm running the following: 34 chokes but have some 36s coming.... air corrector, 160 Main, 145 Pump Jet, 45 Idle Jet, 60F8 E Tubes, F2 Steve Quote Link to comment Share on other sites More sharing options...
T-Bone028 Posted June 4, 2013 Author Share Posted June 4, 2013 I went with the AEM UEGO, but I know another popular option is the Innovate motorosports MTX-L (at least that is what seems to be the most comparable to the AEM UEGO). I went with the AEM due to the reviews I read regarding inconsistent quality of the Innovate, and AEM being pretty dependable. I think the main benefit of the Innovate is their data-logging interface and wider range of AFR. AEM goes from 10 - 20 AFR. Innovate goes 7.35 - 22.4 AFR. I havent been outside of 10.5 - 13.8 AFR's so I dont really see the range issue being applicable. Both are pretty much the same price on Amazon...$150-ish. As far as my jetting: 33 main venturi 4.5 Aux 130 Main 170 Air 55F9 idle F11 emulsion 45 pump jet, 50 exhaust valve I'm going to try F16 e-tubes with 135 main and 180 or 185 airs this weekend and bump timing from 13 to 15 degrees advance. As I make changes, I think thats where the W/B pays off. I also may try larger chokes in the near future. Let me know how the 36 chokes work out...I posted this graph on the Weber sticky, but essentially the author's findings point to the 34's being a better choice over 36mm chokes for 40 DCOE's...but I guess everyones experience is different and the only way to find out is test!

steve260z Posted June 4, 2013 Share Posted June 4, 2013 What sticky is the pdf from? Regarding the Wideband, do you just hook it to a laptop? I looked it up on Summit but still not sure how you datalog with it. Says, no laptop needed. ss Quote Link to comment Share on other sites More sharing options...
T-Bone028 Posted June 4, 2013 Author Share Posted June 4, 2013 Steve, If you dont mind I'm going to move our conversation to the Weber sticky (listed under FAQ -> Engine Components -> Fuel Delivery -> "All who live for triples"). My initial impressions of my DCOE install is now over (they are awesome) and tinkering for fun has now begun! Quote Link to comment Share on other sites More sharing options...
