like the fast cause it does both banks ,not the price , both my chargers have big blocks with headers !!! street cars . auto meter has a bunch of gauges , anyone using one ? OR am I opening up pandoras box !! ones ben on the road for 9 years other is almost ready after 7 years in the building .

not at all! I have an innovate LM1 but I ain't hooked it up yet (bought it used from a CL character so hopefully it is still OK). I have the 8MM bung needing to be welded in. iirc there are some round gauge ones that you can permanently mount in the dash that are pretty accurate. I'm looking forward to the responses also

welding is no problem , have mig and tig in my shop !! thinking fathers day present wife wants to get me some tin i can really use , LOL told her i think i got a idea

Lots of people use the Innovate gauges and they're supposed to be a good. I use the AEM UEGO, it was cheaper when I bought mine and it has a really good reputation in the tuner community. Whatever you do just make sure its a wideband and has an actual digital readout...

I use an Innovate LC1, my brother uses the AEM one, both work ok.

Depends on what you are going to do with it. I am moving to EFI this summer so I wanted one that had an output I could use for engine management. I went with the Innovate MTX. In the year I have had it on the car logging and helping with tuning, it has been great. I have been able to chart the changes in gasoline formulations, carburetor adjustments, etc. Now I have a baseline to reasonably judge the EFI changes and what they mean.

I'm using an innovate LC-1 with an in-dash gauge. It's relatively cheap compared to the LM-1, however the LC-1 does not datalog if that's important to you.

Is there any reason you want to run two sensors? Are you jetting one side of the carb different from the next or running a cross ram intake of some kind?

I bought a LM1 from Innovate before they came out with the LM2. Used it about 4 times and it took a dump. Innovate wants too much money to diagnose it and fix it. I heard the AEM UEGO is really good.

Innovate MTX no problems in 3 + years

Same here

I run two of the FAST analog gauges mounted together so that I can reference the readings as I drive. I do not have any needs to record the data, I just reference them at a glance while I am driving. They are both 5+ years old and I have had no issues with them. (except a recent loose ground wire that was my fault.)

I installed a summit UEGO in my build. It's exactly the AEM unit rebranded with a different faceplate.

I've only had it in and used it for cam break in and 4 different 10-15 minute test drives, but it seems to be working correctly and very responsive to show changes as it relates to tuning. (So far set idle mixture, checked off-idle AFR, cruise AFR)

Price is right too, less than $200
