Ah now.... $250 to spend on that thing!

 

That looks pretty cool, but for 250 I really don’t think I would use it all that much.
But I sure would be popular at the local MEETS.

Question.
I understand how it works by the use of acceleration and vehicle weight, but how does it read RPM’s if it only plugs into the cigarette lighter outlet ?

HE HE HE....
Here's a "cheap" way to try it out:

"We offer a "No Risk 30 Day Money Back Guarantee". If for any reason you are not satisfied just send it back for a full refund"

 

thats crazy it can tell the rpm throught the cigarette lighter... Does it measure voltage fluctuations or what? Damn someone order this thing and get a review done of it!!!

 

I found the manual for it here -----> http://www.gtechpro.com/downloads/competition_1_2_0.pdf Look on the 14th page it tells you how to calibrate the RPMs.
You put your car in neutral and it takes one measurement then you rev to 2000 hold it takes a second measurement then you rev it to 4000 hold then your done and through it DSP it can sense your enging RPM through the voltage fluctuations or something. Any electricians who really know whats going on want to chime in??

 

i would rather buy the apex'i rev-speed meter for the same price.

all these things read off voltage. higher revs, more alternator work, more voltage.

only problem is that if you have amplifiers, you most likely wont get an accurate reading because of power draw.


i think im right on this one... anyone care to give their input?
