Hey, what is everyone's opinions on the Innovative Motorsports LM-1 Wideband A/F Monitor? I'm will be investing in a laptop for college sometime this summer and I'd I wouldn't mind putting one of these monitors on my Malibu to help get the most out of my 357SBC. Is anyone using one these Air/Fuel Monitors? I'm looking at the LM-1 kit with the RPM converter option that way I can get a clear look at what my engine is doing. So what does everyone think of these? Later on, Nick.

Are they a great tuning device? Yes. Are they incredibly accurate in giving you a true A/F ratio? Eeeeh, people can say what they want in this regard, but I don't think so.
What causes the A/F reading to be inaccurate? So what do you reccomend instead of the LM-1? Later on, Nick.
For what they cost, I think it's a good investment. There's alot that can be learned about what's going on with your combination once you start logging data.

Not sure. I see calibrated units come back that read a full point off on every dyno the car sees. Like Todd said, it's a great learning tool as long as you don't rely on the A/F as being 100% accurate. I think the other features you can upgrade to are equally as important.
Things I found which can make it inaccurate:
misfiring cylinder
exhaust leak before the O2
But, I can tell you the LM1 paid for itself when I first took my blow thorugh down the track as my engine went way lean and was able to shut it down before any $$$ damage ocurred.
I bought the AUX box as well. Look on Innovates webiste as they have a forum for support in which fellow users (and Claus) will help to support the product as well other questions you may have.
I can't wait to start reviewing logs that have fuel pressure (first must buy a transducer) so I can see how bad the boost reference fuel pump is hurting the combination.

The few that I have seen up on our dyno read differently than what our dyno wideband read. The cars went quicker after a little dyno tuning even though they thought they were pretty close with the LM1. I hear that they are tricky to calibrate?

There are huge resources on the net to help you thru any issues.
I would recommend any Wide Band for tuning. The lm1 w/ an aux box is great because you can data log. Some w/b don't have any data feature. With a w/b you find out how bad you good tune is..... :shock:
What are you doing in Whiteland???
My WBO2 (it's an FJO Racing, and now what Holley sells) unit has proven invaluable as a tuning tool. It has saved me hundreds of dollars in tuning time by allowing me to do it myself.
It also read richer (like a solid point higher) than the dyno WBO2 at Apex Motorsport, but I believe that was because they stick theirs in the tailpipe where mine is in the header collector. My plugs and knock computer seem to confirm my readings.
I would never go back to a car without a WBO2 and datalogging capabilities - it's like flying blind. Good data rules!
