Hi everyone, I found out that R136 and R138 are bad in my ECU.
Does anyone know what the specs on these are? And where I can get them?
From my research, the resistors are 1k 1/8 watt resistors, is that correct?
If so, can i use these: http://www.radioshack.com/product/in...ductId=2994579
Thanks in advance guys!

R136 and R138 are directly tied to the ELD input.
they are typically removed to increase stability when using the input for wideband support instead of using it as the ELD input.
yes those will work.

I was previously using the ELD as my input for wideband datalogging but found out that there is an issue with smanager and using the ELD to datalog AFRs.
Many people have not had the problems I have had but this posting from the hondata forum says it all:
"Using ELD input as wideband is not a good idea. S300 disable ELD error only, but ELD correction is still working! You can tune maps with wideband at ELD connected, but when you detach wideband from ELD input - AFR will be poor.
Use EGR input in JDM ECU. You need just 2 diodes and 3 junction. And it working best of all.
Maybe sometime hondata will add choice possibility of EGR port input for USDM or JDM ECUs."
yah, Hondata hasn't figured out how to disable the functionality of the ELD input yet.
(neptune has, I'm not sure about eCtune)
