One of the best tuning tools I`ve purchased. Shows me how deadly rich a Dominator is during cruise mode on the street, shows how horrible my tuning skills were before it and my wide open power came alive.

Wow, so far we've got... 1 , one 1 , and one vote. I love this place! FWIW, the kit I bought 2 years ago is a single-channel LM-2 deal which I was planning to set up by putting the O2 bung in my x-pipe to try and get something of an "averaged" reading from both banks.

Interesting......... prior to my dyno tune(wide band readings) I went low 10`s then got my first 9 so,.........
you dont have 3 carbs and an 18" long plenum to deal with.
also, i dont see how a wideband tells you where your motor will make the most power, the dyno did but not the wideband

Well, what I'm hoping to use it for is to tune for a reasonably flat air-fuel ratio across the WOT RPM range, but let my on-track jet tests still determine what the engine "wants" to make the most power.

its amazing your car can even run without one let alone drive a couple hours to the track, run a 10.50 @3700lbs and drive home

It is a tool like any other tool, the end user determines how effective it becomes Mine has help me immensily Buy a dual wideban with the ability to read RPM and store data so you can transfer it to a laptop or some other devise to read and analyse it later instead of having to focus on the gauge while driving, racing or in traffic
I agree! Add this with some experienced advice from guys like Cab, and it really makes a big difference in performance and tuning. It's a must have device in one form or another.
I got the FAST dual band with a portable handheld reader, but I don't recommend it. Get the type Cab describes above. The reason is you can't slow down the playback, jump to a particular spot or transfer the log on a laptop to study it in relation to RPM etc.
It's essencially provides you with a real time reading that allows you to capture one log at a time. It only plays it back at real time too, and the changes to the A/F ratio redings are fast. Especially in a fast stick shift car.... It works, but it's not ideal. It helped me in spite of it's shortcomings.
I have been able to successfully tune using it, but it could be a lot nicer and easier to dump the data in a laptop. The Fast dualband is dated technology.
FAST says they make a software & attachment to allow the hand-held one I have transfer the logs to a laptop, but I couldn't get it to work and their Tech Service regarding it is abysmal!

just making a point that you obviously pay attention to how your car is running to run as well as it does. IMO experience with the wideband, it will not show lean cylinder to rich cylinders. my six pack has jetting all over the place. i do what i have to do to make all cylinders look equal. a wideband just wont tell you that unless you have bungs in all cylinders.
as for guys washing down cylinder walls, sure, i know many bracket racers that slap something together and as long as they can run consistantly thats all they care about. that makes me crazy. puffing black smoke driving around the pits and they dont care. then i see other guys times pickup as the weather gets hotter because there car is so lean.
i'm not saying not to have one, i have one in my car and its ON every time i go for a drive. but can it fine tune a crossram or tunnel ram? it may help a little but you wont get your tune right unless you look at plugs. if you only use an wideband to tune, you could have lean cyl and rich cyl and not know what is going on at all

Actually a good point. A wide band looks at the average, and not each cylinder and obviuosly you want to stay within a range, but there are those of us that have intakes and carb set-ups that not all cyclinders are equal, and this is where more work is required. I try and stick with intakes that don't require a tone of work to get the plugs to look even. For the most part, on a single plane intake and only one carb, the plugs should be farely close...If not, there is more work to do than just tuning the carb for best average A/F. There is more to it than that. Most bracket racers are not satisfied with "runs ok" and we like all our plugs even, but a smidge lean. Our temp swings here in one day can be too much to want to change jets every time the weather changes.

I wouldn't bother building a car these days without a wideband in it. The things are so cheap it is crazy not to use them. I see engines every year that are ruined by guys who have their carbs jetted too rich. The extra fuel washes down the guides or the rings and the motors get toasted. The engine builder I work with sees at least one motor a year that gets killed by a bad tune.
That's exactly what happened to my motor prior to getting a wideband. I have a 3 circuit dominator. I was cruising in the 11:1 range...can you say rich as hell. Had to install a power valve, jet down the primaries 8 sizes, restrict the tranfer slots down to .063, and jet down the intermediate jets to .020. Now it cruises at 14.5-15:1 and the plugs look perfect. So to me a wideband was priceless!

so you couldnt tell there was an issue looking at the plugs before that?

I like the wide band but at the track I use the MPH for my WOT setting then check that with the wide band not the other way around... the wide band is useful in the mid range

I can't imagine ever going back to tuning without one...... The "look" of the plugs only tells you so much.......just like that number the O2 spits out only tells you so much....It shows lean and rich stumbles and you INSTANTLY know it's a lean OR rich stumble, instead of guessing and spending DAYS trying to dial it in....I just thought I had some of my cars dialed in, until I hooked my LM1 up!! lol You can turn just ONE of the six idle mixuture screws on a Six Pack and SEE it on the O2 that's in just one pipe.........There's NO WAY reading plugs will tell you that..... You can also see when your PV opens up........you can watch the motor get leaner as you tip in, then watch it get instantly rich......Plugs won't tell you that and the ass-dyno isn't that accurate........ If it's a race only car that has to only idle and go WOT, you don't really need it (but it can help)........but for anything street driven, IMHO, it's a must-have......
If you can't handle the truth, you're living a lie.......

how have you applied this to bracket racing? I guess I am one of those guys that don't give a flip whats going on as long as the car repeats lap after lap. that's what wins races/money not having a perfect tune. I could care less about being politically correct. I give mine what it wants to make it run the number. but I would like to know what the LM1 says just from curiosity. bring your dang gizmo down and spend a day at the track
