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...

Here is a sticky guide to cams that I got from Clubsi a while ago. I hope you guys enjoy it and just so you know it's through the experience of someone else, not I. Let me start by saying that the following are my comments on these cams. The following comments do not reflect the thoughts of others, ClubSi owners or anyone other than me. These are the critiques and facts that I have experienced from many other people here on the boards and in real life. If anyone feels that I got a critique...

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 our own... So, like every other measurement system it seems that everyone else uses a different scale than we do, but unlike most other instances where we have had the good sense to create different units of measure in this case we all use the same name...

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...

This information is intended to help everyone running a b-series transmission. The charts below list the top speed in each gear factoring in final drive and tire diameter. Obviously, there are other tire/wheel sizes here that I haven't listed however the sizes listed give you an idea when considering the small changes in overall diameter between slightly bigger wheel/tire combinations. The below speeds/rpm drop down points assume an engine with an 8000 rpm redline. 94-01 GSR...
