Hey guys I got a question for you. I'm getting ready to do a few mods (cam, converter, headers,)and before I do, I wanted to get my wideband setup squared away. Other than being able to monitor each bank individually is there any other advantages to a dual setup vs. a mono setup. Also is there any big differences or advantages with using an LM-1 or an LC-1. For the record the tune will be accomplished by using EFI Live if it matters.

 

I looked into a dual setup until a friend of mine (and good tuner) quoted this:

"a man with two watches never knows what time is actually is"

In other word trying to tune with 2 is going to be a lot more of a headache than with one.

 

i agree with radkon. go with 1. dont waste the money on two setups, you will be kicking yourself at trying to tune to 2 widebands. get one, and put it in the passenger side of your exhaust, it is the side that runs the leanest.

 

Interesting quote.

I run 2 widebands when tuning on the dnyo with high hp FI cars, since you never know if one bank will be leaner than the other, I've found more cars with cam timing issues and injector problems this way. (2/4 valve mod motors, not lsx)

It's like having 2 watches, you go by the one that is most conservative, so it you have to be somewhere by 6, and one watch says 5:55 and one says 6, you better be there. Worse case your early.

I'd rather have one side of a motor 11.2 and the other 12.0 than have one side 12.0 and the other unsure (12.8 maybe) if you have a fuel delivery problem

but on a basic na car, just throw the wideband on the other side when your done, and verify airfuel.

Tune by looking at one.
Diagnose by looking at both.

 

Makes perfect sense. It's not like you can tune the two sides independantly of each other, so all you are doing is merely diagnosing both sides.

 

I thought the drivers side was most always leaner than the passengers side, so it's best to tune from that side no?
Isn't the #7 hole on the drivers side?

 

If you have bank to bank tuning capability, get two widebands. If you have individual cylinder tuning capability, get 8 of them. If you are like most people, and have to tune the entire engine at once, just get one wideband and tune a bit on the conservative side. What difference does extra info make if you have no way to deal with it? BTW, extra info is always nice, but realistically, it doesn't do any good if you can't use it. I have read up to 50HP gains with individual cylinder tuning, but knowing that only serves to **** you off if you have no way of doing it.

 

I pull plugs all the time and notice some have more carbon some have less. Some of the plugs look too cold some look too hot.

You are probably right in the case of the gear head looking for that extra boost.

 

The only advantage I see is like was mentioned before, in using it to diagnose a problem. If one side is leaner than the other, it could mean an issue with clogged fuel rails or spark (plugs, wires, coil packs etc).

 

Thats the side my wideband is on. I thought that would be the leanest side.

 

Anybody read this about tuning each cyclinder with a ir temp gun..is it possible.

 

I have a laser heat gun. It wasn't too expensive. I think the problem is that you really need a temp sensor in the exhuast stream.

 

You can always check your trims to get a bit of an idea if 1 bank is out. Its not as good as using a WB but if the trims match up that's pretty good info to say all is good to me.
