I'd get one...

Also, what ECU are you using?

ditto.....

 

are you running an auto pm6 (forgot the name)??

 

factory hf ecu

 

then you need to know how to read codes if its the factory ecu...

1 long blink = 10, 1 short blink = 1

no thats only for OBD1 on the CEL. count the blinks and thats ur code. 5 blinks = code 5, 13 blinks = code 13 ETC...

yup ditto

 

Obd0-B16-PW0 and I get long blinks....

 

Bad ECU maybe? I know you said its throwing codes, but try a known good ecu. Usually when an ECU is screwed the red LED light stays on permanently, you did not mention that, but I'm just throwing out ideas.

thats true but we are talking about a usdm ecu

 

Ok, i Thought i was going CRAZY! I have been messing with this new car i just bought and it was blinking like 20 short blinks in a row, but my B16 car used to throw long blinks. So i thought the ECU was fudged.

Jason.

 

ok, i guess i might be semi-wrong then...i never had to deal with codes that were 17 short blinks...only time i really had to deal with codes where when the car had b-series and it was the long and the short blinks...sorry...

 

OMG i was right and i was the first to say it LOL

are u thowing any codes now that u are a expert it it?
