Port versus Throttle Body (TBI) fuel injection. Needs to be understood. It’s a great topic to research as there is a significant amount of information on-line to read, videos to view, and EFI installations that use one or the other. A bit of history is required. Carburetors were the choice of...

I use Tuner Studio MS as it has all the options I want, the only tuning application for the Speeduino ECU, and is a licensed version. Licensed versions are recommended because there are features/functions not available to a user with a lite version. The Speeduino manual details how to download...

Started the review of the Tuner Studio (TS) software application last night. There are information buttons throughout the application describing the feature/function and if it relates to another feature function. A "note" button may also be included so that you can detail what you have done to...

Mentioned that I would be using the Spark Gap X4 as the basis for this PnP ECU. Have to look at the configuration of the existing board, extremely small and would need to have the board modified to fit the original CFI ECU case. This is a good thing in that there would be lots of room for...

Let's not forget it's a long way down, and twice as much coming getting up!:ROFLMAO::D

Took the Ford to the local garage for the oil pan gasket yesterday. Dropped it of around 11:30 AM got it back around 4:00 PM. Wasn't going to test the exhaust bolt gods; however, it was a $450.00 CDN bill all in using cash. Using plastic would have been another $60.00 CDN. Gasket was $130.00...

The engine tuning, Tuner Studio (TS), and data analysis, MegalogViewer (MLV), software applications, are from EFI Analytics. These software applications, the licensed versions, are powerful tools that you use to do the engine tune, and analyze the engine performance data. Starting with Tuner...

I mentioned this in my thread: https://classicgoldwings.com/threads/1985-limited-edition-and-1986-se-i-fuel-injection-motorcycles.14941/ The Speeduino Project ECUs are used for PnP applications because of the open source concept, lots of interesting developments being done with regards to PnP...

This is a follow on thread to my the 1985 Limited edition and 1986 SE-i Fuel Injection Motorcycles: https://classicgoldwings.com/threads/1985-limited-edition-and-1986-se-i-fuel-injection-motorcycles.14941/. I enjoy anything EFI. This thread will look at the tuning software, Tuner Studio, and...

My loyal followers have decided. I will engage the creative juices and start to develop thoughts on the above two topics. Have to put the GW on hold for a few days. The 2008 Ford Escape requires my attention regarding oil leaks. These vehicles historically leak oil, not all but quite a few...

I have additional thoughts on a plug-and-play (PnP) Speeduino ECU that would fit in the OEM ECU enclosure. The "strawman" that I have considered is using the Speeduino interface board v0.4.4 as the basis for this PnP ECU, with a few modifications such as dedicated tach and fuel pump connections...

Question to the collective and my loyal followers. On the more serious side of this thread :D:D by this author😇. Thoughts on doing a thread on the tuning software, what is available, the interrelationships between the various settings, and what it means for you the user. I have done this for...

Slow day at the office. Have been working on the wiring schematic(s) for this project. Rebuilding the symbol library. Think I have mentioned I am using KiCad, and open source application. IMHO, having an accurate schematic set is just as important as installing and making the EFI system...

18n gauge wire arrived today. Going to be a nice addition to the project. Striped wire makes for a good install in that you can differentiate from the standard solid colours that are predominantly used, and the OEM wiring as well. Had made a wiring schematic with the last time being in...

Slow progress day, so I thought I’d do a post about the ECU evolution; from the original OEM CFI ECU to the one I will be using going forward. The original ECU enclosure/case measured 6 ¼”W by 6 3/4”L by 1 ¼”H. Had two PCBs and operated a “fully” featured EFI system. Had a barometric sensor as...

Short update on "garage" progress. Have the wiring harness connector installed, will do one more confirmation of wiring connection. Have decided to work on the wiring changes needed. The original ECU wiring harness is gone, the CFI system has been modified (for the better I think), and I use...

Getting at the new ECU connector. Takes some thought to figure out how to use the provided wiring harness connector: Have to take the back off, the side that the wires go through, then feed the wire through, add pin connector and insert in the connector. Wire size greater than 18 gauge...

Have the bike on the bike stand, like not having to work on the garage floor. The new Speeduino ECU clone arrived, do believe I mentioned this, a Spark Gap X4 from openlogicefi. Chose this unit instead of the WMTronics Oscelot purely from a budget perspective, both good aftermarket Speeduino...

Road trial yesterday went well. Adjusted several VE table cells to bring engine operation into line with the 14.7 air-fuel mixture. Hear the exhaust "burble" every now and then, looking into this. I have read that some OEMs have calibrated the engine tune in and around the cruising range so...

Reviewing the logs last evening and noticed that the timing during fast idle is approximately 32 degrees BTDC, and when at normal engine operating temperature, 19 degrees BTDC as set in th spark table. Idle timing is "giving the engine" what it needs/wants, and the engine idles at approximately...
