hello, where is the best place to buy a ecm scanner? thanks, tom

 

Depends on your needs.
I'am satisfied with my AutoXRay:
www.autoxray.com

But i think the best solution to diagnose your car is
making your own ALDL-cable and connect it to a Laptop.

 

I'm happy with Ease but to use it you must have a laptop with a serial port.

 

Can u just use a normal pc?

 

A regular computer is fine in your garage but at some point in time you are going to want live road data.

 

Is there a way I can pinpoint my problem I have in my car.. with a pc..?

I have a 1986firebird 2.8L v6 and I am getting HORRIBLE gas mileage! 12MPG! I did a tuneup too, plugs, wires, cap rotor. replaced maf, alternator, and a new egr valve.

 

Could be the O2, or need new injectors. The scannig software would tell you that. I would guess that unless you intend to use it severals times it might be better to let someone else do it. $300+ for scanning software is hard to justify for one shot.

 

wuts wrong with winaldl? thats free? Alls it would cost me is to make the aldl cable...

 

You can get the fault codes out of the computer with a paper clip in the correct terminals of the computer connector block. Check the manual.

 

yes, i know how to pull codes. i'm just looking for a good scanner. i know the gm tech 1, you have to have a "E" pin adapter for 86-88 305/350 tpi. is it like that with the aftermarket scanners? as i have a 86 305tpi. thanks for your replies. tom
