P28 D10 ELD - help

[Lyle_57IAL]

Gday,

Currently on a P28 S300 from a 92 - 95 Eg Civic. Having a lot of difficulties getting my D10 Eld circuit to run. When i datalog a 0 - 5v input into D10 the car will idle extrememly rough for only a matter of seconds then drop out.

I have opened the case and looked at resistors R136 and R138. R138 does not exist and R136 does. So i remove 136 - Then the car will idle extremely rough no matter if a 0 - 5v input is connected up or not.

So my question is. What do i need to do to get this imput working properly?

Cheers

You will need to be much more specific in what it is that you are trying to do and exactly what you have done and how you have things wired. Post calibrations and datalogs showing the problem as well.
