Hello,

I got code 20 (ELD) and code 23 (knock sensor) with the P73 ECU. I has replaced the knock sensor but code has not gone and I pretty sure all the sensor are in good condition and no error with power fc.

I heard many people the would run with P28 and it is the best for swapped engine. Could P28 disabled the knock error code?

Or other ECU should be better you suggest?
Thanks!

 

A chipped P28 can disable those sensors. Run one in my DC4 and one in my buddies B16 swapped DC2.

 

Did you run the wire for the knock to the ECU?

The knock wire from the factory is shielded wiring

also is the B18c gsr or type r spec ?

I think the ELD is part of the underhood fuse box

how are you running the obd2 ecu? i am assuming a jumper harness ?

 

It's a strange thing, there are no knock sensor and ELD wire connect to ECU plug, Now , I had rewire the knock sensor to ECU directly, Code 23 has gone.
I will re-wire the for ELD . But I don't know where is it located and the ELD wire path.

 

here is the pin out

it looks to be on connector D

Thanks for your help.
I know which pin for the ECU input it is. I don't know which one is the ELD signal wire to jump to ECU.

 

May be there are no ELD circuit on my JDM version? What do I do to disable the eld or delete the code20?

 

is this a jdm eg?

 

Yes, JDM

 

Your chassis has no ELD. You can software disable it on a chipped ecu. If that is not an option for you, you might be able to make a voltage divider circuit with a couple of resistors that outputs about 2 volts the the ELD pin at the ecu.

 

well......look into how to wire one in i guess....

 

is it should be below the fuse box?

 

It’s integrated into the usdm fuse box. That’s likely the most complicated solution.
