I am using the AEM unit on my 70 Challenger and I love it. I bought an aftermarket gauge bracket and mounted it to the underside of the dash above the trans tunnel.

Thanks for the responses. I need to keep my budget around the $210-$220 mark (FAST or AEM units) but I can buy a gage bracket at my local auto parts which is no big deal. I think that the Innovate unit is out of this budget (thanks DT for the pm's on the extra items required) and I like the simple look of the FAST gage. This info give me something to think about over the next couple of months. Thanks again for the replies.

Shaker, How much fluctuation do you get during a drive with that digital gage?
Thanks

I get quite a bit of fluctuation while driving the 4 speed and going thru the gears. At a steady cruising RPM it does not fluctuate much.

The steady cruise what was I was curious about. Thanks again for the reply.
Do we have any FAST vendors on Moparts?

I have the LM-2 with the optional analog gauge in my Coronet. I have found that when racing, I can look at the gauge enuf to see that I'm safe, but the logging to look back later to tune is very nice. I wouldn't discount the desire to be able to look at a log to make adjustments later on.

What is a number to shoot for when checking the A/F ratio at idle, cruise, and WOT. What is considered too lean or too rich? Thanks

14.7 is 'the target' so to speak, the theoretical balance point. In practice, often you need to idle richer because the engine is not that efficient at idle. The specifics of your engine will make a big difference too for what a/f will make max hp and how lean you can go before detonation.

Thank you once again to all of the replies. Can anyone with an auto tell me what you are getting in gear at a stop?

Would the innovate LM-1 be adequate to check basic readings at idle & cruise?
