can i just try the 1.5v battery test on different empty ecu pins until i see an input?
could that casue damage to the ecu tho?

 

On USDM cars, pin 73 is used for MAP, and pin 74 is a fuel level sensor. Pin 73 should definitely be MUT38 even on your car. Pin 74 can be read on MUT3E. Rear O2 should be pin 75 and can be read on MUT3C. You might want to check your wiring into the ECU.

 

i'll give 75 a try tomorrow
this is how my ecu is wired and i have checked the n/c do actually mean no cable connected to that pin.

my ecu pinouts

 

I've got most of those pinouts from MLR as well. :-) The Evo 5 thru the Evo 8 all seem to have pretty close to the same pinouts. The main differences appear to be sensor inputs being added to later Evos rather than things being moved around.

 

quite surprised that the spare adac inputs haven't all been found and mapped out for the various ecu types as inputs are a tuners best friend!
i'm having trouble understanding how req 38 and 12 and 3c can relate to 1 single pin input?

 

They are well known for the USDM 8 and 9. I'd bet money that the pinout-MUT relationship I mentioned in the earlier post is exactly the same for your ECU/ROM as well.

 

as you've probably gathered fred the mut stuff is over my head

 

Have you had a chance to double-check the LC-1 and MAP sensor wiring into the ECU?

 

double check it? if you mean to verify the inputs are the correct voltage range and are rising and falling as expected then yes they are correct.
as said lc1 is working correctly and evoscan is reading it with all the scales correct etc on pin 73 and request 3c
"wbo2" was the reference log item

 

never actually got this sorted.
there is now a USDM rom that will port to jdm (thx ziad)
does that rom have inputs and requests all figured out ? or atleast 2 1 for LC1 and 1 for boost?

 

Lee, did you see my ADC thread on MLR?
