Yesterday was a write off, weather did not cooperate for road trials. Good day to peruse the forums for pearls of wisdom regarding engine tuning, barometer sensor install, and such. Found some very good information regarding the four-stroke timing cycle that made sense of the information I have...

Corresponding with a fellow in the UK. He is reverse engineering the '85 OEM ECU. I believe I have mentioned this previously. He is looking into the programming for the travel computer as well. We are having a conversation regarding the OEM engine timing. Specs are for an idle timing of 10...

Going to be installing a remote Baro sensor and using one of the OEM CFI PB sensors. Bench tested it today, had done before, and all is well. Will be using an existing ECU 5V and ground circuit, just need to run a signal wire to the ECU. The PB sensor is a ND 179800 sensor, and this sensor...

Road trials progressing. As mentioned new to engine tuning, great learning experience. Getting the fuel correct is key so working on the VE table with a few small tweaks to the spark (timing) table. Used the AFR table generator to get an AFR table. Hard to tune the engine scientifically at this...

More thoughts on this type of project. Have most of the components that I think are needed for a pilot project, bench test of such a project. Need a Hall Effect sensor, wouldn't hurt to have a spare available. I have the 36-1 trigger wheel. The 1500 engines have a 12-1 crankshaft trigger...

A bit more information to digest. The NO2C Speeduino interface board is the same size as the Arduino Mega 2560 microprocessor - 8X4X0.2 cis. OpenLogicEFI (previously Detonator) Pre-Ignition X2 assembled - NO2C clone - $99.00 USD w/4 bar MAP sensor installed – QTY 1. Comes with the...

Mike - easiest fix if the ICU goes south is to replace with an old identical PnP ICU. If you are adventurous, a new unit as I am mentioning. I am going to do a wiring diagram to indicate what I think the wiring should be for a Speeduino ECU that has the NO2C interface board, maybe a UA4C as...

The forum has been rather quiet so I thought I might do a what-if thread regarding the GL1200 engine ignition control module (ICU). Don't know if I have covered everything, but this is a topic that many may have been thinking about, not so much doing this type of project but what if this little...

Road trials are progressing. Tried a new tune with an VE table based on an AFR of 15.0:1, not going to happen, too lean. Dropped back to 13.0:1, went for a ride, changed AFR to 13.5:1, just on the cusp. Adjusted timing a few degrees, will need more time with this. There is an Acceleration...

Road Tunng - more info. First need the tuning software and data logging analysis software. I have this software, licensed, and have just upgraded to the more recent upgrades. Have Tuner Studio MS Ultra and MegaLogViewerHD. This software is essential for engine tuning. It was mentioned...

Continuing with road trials. Lots of good tuning recommendations from the Speeduino forum. If this were a car, could have someone with me changing engine tune parameters on the fly, could do the same on the bike, but never easy doing anything extra on a bike. Have to change my tuning process...

I picked me up a Big Blue lift a few years back and had an HF style lift as well. Got rid of the HF style lift took up too much room in the garage, the Mrs keeps insisting her car has to be in the garage as well. The Big Blue lift works well. All lifts have some quirks, but the Big Blue lift...

Best item since sliced bread! Have you ever needed a third hand for a flashlight or the trouble light you are using is too big for the area? Check out these LED Flashlight gloves, I got a pair for Xmas and have been using them on a regular basis since: These gloves can be battery only or...

Thanks for reading. Have started a "reflections" thread over on the Speeduino forum. Intend to consolidate what I have learned and even include some pictures.

It does take time to use a program at the start. I find that when I make changes to a component/whatever, it may not line up again - frustrating. I took some more time and finished V1.0 and it's not too bad. I made some symbols for fuel injectors and COP components, added in the WBO2 sensor...

Weather has not cooperated, trials on hold, but have been progressing my learning new schematic type app, KiCad. Not the easiest to learn, but I intend to conquer this one. I have tried a lot of drawing/schematic type programs in the past, got frustrated and into the bin they went. Have a...

Quiet here as well. Got a bit of snow, snowblower works well. Learning a drafting/drawing app, KiCad. Have been working on the new CFI system wiring schematic. Can't do much with the GW until the weather improves. Hockey weekend is here in Victoria with the CDN teams on the ice, going to...

Took a picture of one of the many grounding points: One wire with four attached with the infamous blue tape, just one of the many splices/joints in an '85 GW Limited Edition CFI wiring harness. FI models do not like noise and with this type of wiring, there is apt to be lots to varying...

Quick update - have been doing a few rides. Data from the rides is interesting. Seeing how the engine is operating and being able to make adjustments is quite satisfying. Started this project to get rid of the annoying fuel smell on start and during a ride. Have accomplished this so project...

Very nice and welcome.
