I bought that demon and he PM me that he had an engine sim. for sale for $85. :noel:

But yeah I'd like to see a RHMT version, I doubt anybody on here is doing one. :noel:

done

Post by: turbohf on August 31, 2012, 01:34:40 PM: i made 2 of them years ago. obd0 and obd1. it was just a 9v battery to power up the ecu, and a LED on the CEL wires. it blink? ECU is fine, solid? try again.

made it when i blew up the crx then sold it. so i couldnt in car test anymore.

Post by: walter on August 31, 2012, 02:22:15 PM: how did you do that exactly?

I remember that stole your idea to test a couple obdo ecu's

worked perfect

how did you do that exactly?

power, ground, LED signal from MIL ECU wire, other side to ground.... ill look for pics later, they are probably on old comcast.
Title: Re: DIY ecu tester?
Post by: turbohf on August 31, 2012, 04:06:22 PM: obd0 i used pins: A13 power, A16 ground... you hook up a standard 9v battery. if the light in the ECU blinks your golden.

obd1 i used pins: A25 power, B2 ground... one side of LED to power the other to A13, D4 to ground... again 9v battery for power/ground.

havent found pics yet. im sure they are on my PC... and i still might have these testers around somewhere.

found this one that leed did forever ago. way nicer than one i made lol

only tests that its not a solid CEL, not to trouble shoot the functions of the ECU.

but , according tester , ecu is OK. :-\
Title: Re: DIY ecu tester?
Post by: JaredKaragen on October 14, 2012, 04:41:33 AM: add a resistor to the CEL circuit if your using an LED; it doesnt get pulled down enough and lights up dim.

damned LED's are efficient these days.

My moates engine sim always has dim lit LED's.
Title: Re: DIY ecu tester?
Post by: walter on October 14, 2012, 05:13:20 AM: i dont know how efficient is this tester...it says my ecu is good but when i connect to the car is throwing solid cel.. :noel:

P.D already ordered a moates engine simu..
