Plan to go for the AEM #30-4100 wideband for my carb set-up.
Comments please.....be honest. Let me know what ya think

Thanks

 

I bought the innovate wide band, it was the cheapest and it works excellent, i went from a price stand point and i am pleased.

 

I just got one from ws6store.com I let you know how it is in a week, when I install it.

 

I have the AEM eugo. Keep in mind that you cant data log with the aem. Thats the only thing I don't like about it. Its hard to watch a wideband when your sawing at the wheel banging through the gears.

 

Well I am not totally committed to the AEM just yet. I can't afford the data logger just yet. But it may be good to have that as an option later. JONES89RS, which model do you have? Aren't they all around 200.00 or so? Thanks for sharing the information.

 

I bought 2 of the analog UEGO's at Summit for like $149 each (on sale) earlier this year. I thought they had 2 extra pins or a 5v output that could go to something like that allowed for logging? No?

I think having a carb on a newer technology motor like these...well its almost mandatory for getting the most out of your equipment aspect, and ability to monitor something that a PCM/ECM would be doing in the OEM config.

Anyway, I like them at $300 for the pair... they let me see (and tune) my tucks a/f ratios at idle, cruise, and transition phases.....and see some of the WOT readings.

bottom right:

 

THis is the one i have, works bad *** and the electronics are all internal with the gauge, it comes with software for the lap top for data reading ect, i am sure it will data log but i have not tried, i just look at the gauge when tuning.

Was 160$ when i got mine but the price is up on EVERYTHING in our slumped economy.

 

Heres a good "in theory" question. Can you get away with running 1 sensor, in 1 pipe of a dual exhaust set up with a carburator? I would think as long as the intake manifold dosent have any distribution problems (I.E. Big block chevy) it would work find for dialing in your combonation. Eric L

 

Most guys just run a single sensor in one side or the other. There are dual sensor units out there, but like I said most guys only run one side.

I know there are some guys who run dual sensor units. Would be good to hear what they see in the real world.

I will tell you one thing, WB's make tuning a carb easy, but then they start showing you so much detail that it can get overly complicated again. The data logging is nice if you want to tweak things like accel pumps and transition circuits.

Here is an interesting WB comparison. Not the exact model Zones listed, but I think it was the prerunner to it.

I run the single in my passenger side header.

 

x2...

 

I too have my sensor in one side.

 

I sometimes see about 1-2 full points difference between one side or the other while tuning.
If I had only one....it would be in a H-pipe or X-pipe.

 

So when that happens how do you change the tune to make them match?

That was my first thought, lol. Looks like a good place for a split dominator on a divorced intake, lol. Hmmmmmm, nawwwww, thats a project for someone with more money and better fabrication skills than I, lol. Eric L

 

My 750 Holley Street HP carb has a 4 corner idle, that's sitting on a GMPP LSX/LS3 dual plane intake. A little tweaking here...a little there... and it balances out. As one might think though.....having both sides of say the primary side at say 1.5 turns out....you wind up with one at 1.5 out and the other anywhere from 1.2 up to 1.8 out?
Or...you have one side showing richer/leaner then the other.

So....which is more accurate? The AEM UEGO's? Or keeping the same number of turns on a Holley on each side?

 

Ahhh, theres the differance. I forgot you have a dualplane. I never thought about it that way before. That is kinda a cool feature to using a dual plane. Im still not convinced that using a dual plane intake on a motor with heads designed to wind to the moon is a balanced combo though. I guess thats another discussion for another thread, lol. Hijack over, lol. Eric L

 

....well all I can say is it seems to work! This combo makes a lot more power then my 383 sbc did. And to tell the truth....never planned to rev it past 6500rpm (ok maybe 6800 for the 1-2 ) or so in its current config.

 

Sort of the point I was making.

I think having both sides instrumented would be valuable to look for other problems. Like a dead cylinder or exhuast leak. But not sure I would trust the accuracy of the gauge enough to start tuning one side of the carb differently than the other. A problem at idle would be a bit of a don't care to me. Especially the way idle AFR readings seem to fluctuate from day to day and with engine temp. For an idle imbalance I would probably just split the difference and keep the screws the same all the way around. But I absolutely wouldn't go beyond idle screws.

The AEM UEGO didn't score too well in accuracy in that wideband comparison link I posted a couple of posts back.

I did see an Engine Master challange where the guy who won used a different booster in one venturi of a dual quad set up. But he was looking at exhaust gas temperatures on the individual exhaust ports. Beyond my skill level for sure.

I guess what I am saying is having sensors on both sides would just confuse me and make me not trust the readings.
