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

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

not sure the purpose of all that jazz. Fucker works plug in it a car,doesnt work you suck at soldering

done

turbohf · « **Reply #7 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.

walter · « **Reply #8 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

power, ground, LED signal from MIL ECU wire, other side to ground.... ill look for pics later, they are probably on old comcast.

turbohf · « **Reply #11 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.

turbohf · « **Reply #12 on:** August 31, 2012, 04:18:29 PM »

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.

92CXyD · « **Reply #13 on:** August 31, 2012, 04:49:49 PM »

Awesome

walter · « **Reply #14 on:** August 31, 2012, 04:54:37 PM »

no problem, here to help

walter · « **Reply #16 on:** August 31, 2012, 05:06:14 PM »

another question, how to pin for read codes? thanks HF!!!

that is to read codes. it will auto throw iat/iacv/and some other cool shit lol.

walter · « **Reply #18 on:** August 31, 2012, 05:47:52 PM »

wow! nice!!! double job, check if ecu is good and if there is a cel, it will shoot the code , correct? Thanks!!!

JaredKaragen · « **Reply #19 on:** September 06, 2012, 12:14:02 AM »

I have the moates model. Worth every fucking penny!

walter · « **Reply #20 on:** September 14, 2012, 09:24:00 PM »

Did it, tell me what do you think.

ECU 1 , stock ecu, checked it works pluged to the car, not cel. blinks but led light very low.

walter · « **Reply #21 on:** October 03, 2012, 05:00:09 PM »

finally i made it better, i will shoot some pics soon, idk how reliable will be this because i tested a ecu i chipped yesterday and found this problem.

http://www.realhomemadeturbo.com/forum/index.php/topic,20307.0.html

but , according tester , ecu is OK. $:-\$

JaredKaragen · « **Reply #22 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.

walter · « **Reply #23 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..

P.D already ordered a moates engine simu..
