Default do I want a digital WB afr gauge, or the flashy light one?

I'm getting an lc-1, and trying to decide if I want to look at a #, or look at red, yellow, and green lights. I already have the flashy light "stoichiometer," and I am going to run MS.

I was thinking the lights would be easier to read if something "goes to ****"...at least I get a color designation.

What do you guys think?

I find myself ignoring the colored led's and only looking at the number.

what's gonna "go to ****"? injectors don't just stop working, ECU's don't make up a new tune as you're driving... if your fuel pump dies, you'll know it.

If you want a digital...and the led sweep..just get the AEM one..you can get it for like 250...which is cheaper than the LC1...and a gauge.

If it's easy enough to read while speeding on streets, it should be alright where you don't have to worry about much traffic or pedestrians.

My AEM just has the gauge so I figured, I'd run it
and boost is kind of important...EGT might be useful, but thats a lot of gauges....2 on the a-pillar is enough rice for me

Yeah AEM is probably more supported if you're going to be plugging it into an ecu or something.

I think both AEM and LC-1 work great with the Megasquirt, I just got a great deal on the AEM and I like the gauge and how it looks in the A pillar with the boost gauge...

detonation maybe, and AFR won't tell me that...especially sense I don't have knock control yet.

MS Knocksense would be a much more useful way to spend $100 than a WB gauge.

I was going to wait and see how to hook it up with ms pnp...since I have no clue what its going to look like. I guess I could hook it up through the CLT...right?

a WB is great when you are tuning. not useful all the other time.

I run a narrowband O2 gauge to keep an eye on fueling (gives me enough info for keeping an eye) and I use the narrowband with the MS to keep stoich off boost.

I also run an EGT gauge. That will tell me a lot about how the motor is running.

why not just go off the data logs, and watch the computer screen when tuning?

Ever tried watching your tach/speedo all the time while driving in a car your not used to? It takes a second to see how fast your going...its even harder to check out a computer screen.
