I own the LM-1 from Innovate Motorsports. I love it, it works as advertised and has enough features to keep me happy. The big thing is Innovate's forum is very active with knowledgeable users including the engineer who designs their products. You won't go more than a few minutes without getting your question answered. I met the head engineer at the PRI show in Orlando last year and he's a very nice guy who knows his shit and makes some really badass high end products.

 

all my tunes have been done using the innovative wideband. its very accurate and good quality. i recently bought the AEM and will be installing it shortly.

 

With the Innovate, you don't need the gauge, you can see the A/F ratio on the display. BUT, I know that sometimes its nice to have a simple gauge and hide the box. You can either buy the LC-1 I think it is, which is just a gauge and sensor that doesn't do datalogging but its like half the price of the LM-1.

Or.....

What my favorite is, get the LM-1 which will datalog in the box without a laptop (I datalog A/F ratio, MAP, and air temp). The LM-1 has 2 fully programmable outputs. You can set one of the outputs to mimic a standard narrow band sensor. Then you get the Auto-Meter A/F gauge only (to match your other gauges) and wire that to the LM-1 output. So the LM-1 is tricking the gauge into thinking its a narrow band, but you're seeing the accurace of the wideband. All you have to do is tweak the output of the LM-1 so the middle light of the gauge is lit at your preferred A/F ratio.
