ECU Error Codes Here's a handy chart for pulling your ECU codes. Pulling the code is a fairly easy process. For 92+ Honda's and 94+ Acura's: Before you can start reading the CEL (check engine light) in your dash, you need to 'jump' your ecu. Here's how. Located the factory two-pin connector of brown and black wires near the ECU on Civics del Sols and Integra's, or behind the center console for Preludes and Accords. Pull that 2-pin out of the main harness. Using a wire or paper clip as a...

Honda Engines List This is a list of commonly used Honda Engines for hybrid swaps in other Honda vehicles as well as other make vehicles to increase performance in the base chassis. Some engines may require a mount kit or shifting change (bar to cable, different length linkage, etc), hood alterations or oil pan customizations, and/or extensive wiring changes. Not all swaps are legal in all areas for on-highway use, so do consult your local laws before choosing a swap. Code Displacement...

United States Vs. European & Asian Octane Ratings In Europe 98-octane gasoline is common and in Japan even 100-octane is readily available at the pumps, but this octane nomenclature is misleading to Americans as foreign octane ratings are derived entirely differently from their own. So, like every other measurement system it seems that everyone else uses a different scale than the United States does, but unlike most other instances where we have had the good sense to create different units...

Well, I see a lot of weird stuff when people start talking about all these motors. I tried my best to gather it all from Hondas site into one place, hopefully it can help some of the confusion. If someone sees something I missed, let me know. This is a list Japanese models, and their respective motors, not USDM counterparts, those are pretty known already. I did not include B series models, even though they are mixed in the models and years through out, they are well documented already...
