First Test Ride of My Honda Pacific Coast on Fuel Injection

After literally years of work, I finally pulled my Honda Pacific Coast out of the garage to test it out for the first time ever on fuel injection.  The tuning went well up until I hit a slight snag.  I had the exhaust cover sitting in the trunk during the test ride.  That cover ended up hitting the battery cutoff switch that I installed several years ago.  When the bike lost power, it backfired.  The backfire blew out the wideband O2 sensor due to a JB Weld failure.  The moral of the story is that I need to weld the exhaust bung in place.  A friend is going to come over and do the welding later this week so that I can get back to my tuning next week.

 

After so many years of work, the bike is FINALLY starting to run with fuel injection.  I do believe this makes me the first ever in the history of Honda Pacific Coast motorcycles to ride one using fuel injection.  Huzzah!

Getting Closer with the Honda Pacific Coast PC800 Fuel Injection Tuning

I spent some time today on my Honda PC800 fuel injection conversion project.  I am getting the tune file together so that I am ready to take the bike to a dyno for final tuning.  The biggest things that I still need to address are 1) tidy up the wires, 2) adjust the TPS sensor so that it can sense low throttle positions, 3) finish up the primary tune, 3) figure out the enrichment settings for startup/warmup and acceleration.

 

I’m going to try setting up a very old NetBook running Ubuntu with TunerStudio so that I can have the ability to modify my tune while I’m out and riding.  Also that will allow me to more easily log data.  At some point I’ll probably get the BlueTooth wireless adapter to be able to log data with my phone while I ride.

 

Slowly but surely my bike is coming along!  By summer, I think I’ll be out and riding again.
