If you can get the LM1 working, especially with RPM, it's a great tool. Try the full recalibration. One time, I don't remember why, but I had to reload the firmware. Another time a battery change solved whatever it was.

Here's a couple of screen shots from an dyno day to years ago. As you can see the Innovate's response was rapid. No question that the primary side had a pretty flat AFR for the pull, and the secondary needed work with the bleeds and high speed bleed. However, it doesn't show power or torque. Best you can do is compare slope of rpm.

The dynojet's WBO2 in the tailpipe was very damped or slower responding. On the other hand, effects on power and torque can be read at any mph or rpm. So this is also useful.

Also notice that some of the pulls show all three gears (727) and others only 3rd gear. With a stick car, I think the dyno owner will prefer you get it into either 3rd or 4th early. Chirping tires on the rollers is probably not a good thing!
