Hi, I'm running a USDM p28 with my Canadian 98 jrsc gsr and I'm throwing CEL 20 & 41. I pluged this ecu into my buddies obd1 gsr and it gives him the same code.

Is this a basemap problem? or a ecu socketing problem? This ecu is prepped for Hondata, however I'm not running Hondata. My ecu has a custom chip using Techtom.

I bought a Hondata prepped ecu because in order to run a chip the ecu has to be socketed anyways. Is there something that is done to a Hondata prepped ecu that isn't necessary for a normal chipped ecu?

 

USDM ECU's look for an ELD.

Canadian ECU's did not look for this sensor because the car isn't equipped with one.

 

Canadian ECU's I'm sure have ELD's. My friend whos a mechanic at Honda verified this. I'm not sure about obd1 ecu's but my 98 integra has one. He told me he's replaced 2 fuseboxes as a result of code 20.

 

My 92-95, 96-99 Civic and 98-00 Teg Helms disagress with you.

Question then: How many wires do you have hanging off of the alternator connector - 3 or 4?

 

Yes, I thought so too, the Helms has a (USA) beside it.. but, he says any honda technician will tell you our cars have it .. My buddies a senior technician there.. I don't want to doubt him because he definately knows his ****.. I'm not saying that he knows it all.. but when I told him CEL 20.. he immediately said .. ELD.. Electrical Load Detector.. so I knew he knows about them.

After asking him if our cars has them he says yes.. civics, accords, and integras have ELDs. He didn't go into saying which specific models..
