i was thinking about getting one of these to do my tweaking and tuning.

For $200 bucks it would seem like a great way to test changes in jetting and performance upgrades and its a lot cheaper than multiple dyno pulls.

does anyone have experence with these?

are they fairly accurite?

My kids gave me the previous verion a couple of years ago...
I took it to the track once for a test and it was around +_.2 sec if I remember.
I never got a ticket, but it seemed to make me speed/accelerate more than I should though, so it's been on my shelf ever since...
For tuning, a better toy has been the LM-1 wideband O-2 sensor/data logger.

i got one!

i love it, it seems accurate and it is self aligning.

the older version you had to degree it by your self.
it has a great display and it shows 1/8mile also.

The shiftlights are great too.
you set the max rpm and it will blink with 1 light first,then 2 lights and finally 3 lights.

many options and a great display.
200 bucks well spend i would say.

I have the previous version and I used it a lot, mainly for 0-60 runs. It's very informative to be able to get a real readout after the run. Short of going to a dragstrip or chassis dyno, it's really the only way you can quantify the effects (positive or negative) of the numerous small changes we are always making to our cars.

Very good investment, IMO...............

Be very cautious with it on the street. It's easy to find yourself looking at it and not the road...and it'll make you turn public streets into dragstrips...IMO

thats why i focus on the 1/8th miler times and not 1/4th mile times.

with the odler version you could only get the 1/4th mile times, and i must say running 120 mph in my village was fun BUT DANGEROUS and IRRESPONSIBLE! :D

The older version gives you 0-60 times as well as 1/4 mile. On the street, the 0-60 time is the only thing that really matters as far as I'm concerned. Plus, it's the benchmark that every magazine and manufacturer utilize in describing acceleration.

My best 0-60 is 4.5 seconds, which I consider pretty good for a car with standard BF Goodrich radial tires. I know I'd do way better with more traction, but I like driving around in a street machine, not a race car...........

understood, i do live in a fairly rural area and there are a few places where we can play with out endangering others.

I have always utilized this tool for tuning both chassis and engine. It is also very handy when street racing to determine the best launch technique for your car ect. I use it to know different sandbagging increments Example: Know that using my adjustable MSD timing computer to pull out 4 degrees of timing yields lazy start ( maybe it allows hooking up easier ) and is .3 tenths off normal tune, meaning once the money comes out its just a twist of the knob to get there first. I use the car in second or high to measure HP although high vibrations skew this. The uses are unlimited. you can 60ft it only which saves a lot of wear and tear getting your launch down.

I have a brand new one (opened) in the box that I really never used that I would be willing to part with if you want it.

I can send pictures if you or anyone is interested. I plan to put it on ebay with some other nice parts that I have laying around......

I take the first $135 including shipping.
