comprehensive Greddy Informeter Thread - Page 2

I'm sure the problem with freezing up is a lack of power regulation. I get this idea from my own project that relies upon the 12V power system on these cars. The cars actually put out up to 14V. 14V unregulated to a Microcontroller (chip) wanting 12V will mess things up (temporarily and possibly, but not likely, permanently). If you want to test it out and be perfectly safe you could add a 12V single output, non-adjustable, voltage regulator to the circuit. ( http://www.digikey.com/scripts/DkSea...e=MC7812ECT-ND) They give off heat though and may need a small heatsink.

Here's an easier one to get a hold of: http://www.radioshack.com/product/in...entPage=search

Basically it'll take in any voltage up to 35V and make sure that it outputs something very very close to 12V. The voltages above 12V will cause it to give off heat, but I'm thinking that the highest you'll see from the car's electrical system will be 14.5V so you shouldn't need a heat sink.

As you can see the regulator has 3 pins. 1) voltage in 2) ground 3) voltage out. Read the spec sheet to see which pin is which and the wiring should be pretty simple.

Ok...last rambling post

Buy a used one on ebay. Paying anything north of $300 for one is crazy.

anyone get this to work on a 07 sti? tried both methods of wiring directly into odb port and cig lighter. unit says there is a communication error, response... any ideas?

Wow, awesome write up!! Though I dont have a Greddy Informeter, My blitz r-vit I color works exactly like your Greddy Informeter in terms of installation and functinality... Wish I could post some pics but got none right now..

i've just installed in my 08 sti, is very nice and smart but i don't know how accurate it is ...

anybody knows why this infometer can not read the speed ? linked by speed are trip, power, Gear Pos ...etc wich are not running

thx
