Just a note Andrey that the Legacy console, thinks the 0.2 proteus board is F7 and won't let me DFU. I downloaded the F7 Firmware and used the console from that package to DFU then used the correct Legacy firmware and it works. Not sure how the consoles got mixed up.

Latest update after a few setting changes to get the throttle to respond better. There about 1 inch play in the pedal before it starts engaging the throttle so we're having a tough time getting our foot down to the point where it engages the pedal. That should be fixed with a change of a spring, but...

@lambo97:

Instead of this plastic stuff:

The M73 has a long angled plastic tube inside the intake that condenses oil vapor. It connects to the center of the this plastic PCV end cap. Without it I wouldn't have PCV. I don't mind the black it fits the motif.

I'll perform a run up to operating temp next post. I'll show the AFR delta just after idle and at operating temp. I'm hoping the 3/8ish ID hose will get me closer to balanced. Last run I was 1.4 delta between banks at operating temp.

Ran up the Diablo's car motor last week, idles great. AFR is a little off still. I guess due to the side to side differences between the intakes. So I continued to look for a crossover tube solution to equalize the vacuum across the intakes. I purchased new PCV's, drilled out the location of where t...

Update 36.857 Motor is in and run up once 2 days ago. Lots of raw fuel coming out the back, even though I leaned the crap out of the VE table at idle until the engine starting a slow up and down pulse. Running through a new compression check to make sure all is well after rebuild. Checking plugs ton...

I have to hold down the AT button while I boot the device to get into AT mode correct? 2 second slow red blink.

What Terminal are you using. I've tried Putty no go, every setting just sits there. Just a note that I can connect to the Bluetooth no issue, with pass 1234. Just would like to increase speed and set name. I was using "Mybotic Serial Connector" terminal to successfully connect to HC-08 but...

OK I have the HC-05 and USB adaptor. I was able to terminal into the HC-08 no issue but the HC-05 is not responding. I'm in AT mode slow blink 2 seconds. Do you need a voltage divider "resistors" to get the V down to 3.3 to be able to communicate with HC-05? My terminal connects but AT com...

The module description is: SH-HC-08 Bluetooth 4.0 BLE Slave Module to UART Transceiver for Arduino Compatible with iOS I've already connected using USB to Serial cable, set Bluetooth Name, PIN and 153600 Baud for serial communication. I can talk to it using AT commands so I'm guessing it's compatibl...

I'm adding this to both my .4 and .6 Proteus. Was wondering if the HC-08 Slave module is fine to use? OR do you need both HC-05 Master / Slave module only for this to work?

Interesting, Soon we will be able to run Pulsejet or Turbine with Rus EFI!

Finally an update, after a few months working on a 460 Ford big block. I had to finish this motor and transmission for a friend. All done, but too bad there won't be any EFI on this motor. 460 Ford Big Block image.png image.png image.png Finally cleaned the block surface and installed the head gaske...

Hey JRD would you be interested in building me a few of these. I can desolder but would have trouble soldering the cap.

Hey I saw that a few pics up about wireless possibly Bluetooth connectivity added to the board. Is there anything stopping us from using a remote bluetooth adaptor connected to the USB port? Also the adding real time date to the log, am I to guess that when the key is turned off the board shuts down...

I ran through a $350 set from Latvia for the first rip and strip. So this time I only bought the gaskets I didn't couldn't use RTV for. I got the head gaskets from Ebay both Victor's so at least I got them . The ones I really didn't want to make were the upper to lower front case gaskets that are a ...

Update: Heads are back, Was waiting for Gaskets from the only place on earth that seems to sell parts for M73........Latvia Should be pulling the engine from under the cover and starting the reassembly. Machinist resized the stem guides, 3 angle grind, all looking clean and no more air leak! Should ...

Ok the Motor is out and the heads are at the machine shop. 3 angle grind, deck, resizing of the valve guides to match the valves. Perfect AFR here we come. image.png image.png In this picture of the lean side, we can clearly see oil leaks. I marked the 3 cylinders that had dark plugs. Cyl 8, second ...

So there are 3 problems. Cyl 8 is 60 pounds under testing. Cyl 11 is 170 where all other cyl are 205 to 210. And an Oil leak making nasty plume behind car on that bank. I took the springs off and spun them with a drill for a few minutes. They seems to seat nicely but the intake based on the position...

So bad Cyl aside I can't seem to find the reason it sprung an oil leak inside one of the cylinders. Oil smoke is the reason I moved away from an old Carbureted V8 and this is pathetic. Working until 2:00am most mornings for months on end and it comes to this. So I took a week off so I could loose so...

Hey there, I was frantically testing last week before we had a family vacation planned for this week. I found a dead cyl 8 this time, plug was wet. Ran 2 compression tests to make sure it was an issue and was only getting 60 pounds. I ran air into the cyl and I could heard a hiss in the intake and e...

Yes I changed the coil cable and plug. This reading is after the change in pulling all the plugs again tonight to see if there are more issues.

Update crossover tube installed. It's 0.6 Inches in diameter. It's brought the banks closer together around 1 point difference in AFR.
Now Time for Tuning to get the AFR closer to Stoich.

Getting closer. Decided that a crossover pipe between the intakes might equalize the vacuum and provide a little extra air at idle. Off to the home depot for some knurled fittings.

Just thinking of how the V12 was originally built as 2 separate motors with a common crank. I saw this motor running smoothly with using 2 separate ECU's with 2 sets of sensors. If we could virtually assign injectors, MAP and O2 to separate banks, theoretically even down to the cylinder you would be...

that's epic! thank you for betting on rusEFI Hey Andrey no problem, there really isn't any other option to run sequential V12. Also if I was running a less complicated motor rusEFI would be the most cost effective and easy solution to run most any motor on the market. On another note, thinking abou...

Todays update, I worked with Matt the Wideband and Proteus developer and after updating firmware the 2 widebands are working. They are confirming the right bank is way more rich than the left bank. We did a plug check and it seems Cylinder 4 may not be firing. I've ordered new copper plugs (easier t...

Ok Finally got a video of it running, lots of tuning, current issues with widebands not reading anything but working through that. One bank seems richer than the next bank so I'll go through and do a check of spark to each cylinder.

Matt and Andrey were on the money 30 Degrees trigger offset is perfect. This after going through the Proteus trigger setup, step by step in the manual. Getting late tonight still have to put the plugs in and put all the wiring back i took apart for diagnosis. Next post could be video of engine runni...

Getting close to starting: ETBs work, TPSs are checking in, Set base trigger to 28.125 Degrees (360 degrees divided by 64 teeth on flywheel equals 5.625. Trigger is 5 teeth away so 28.125 degrees initial) I'll spin it over and check timing first but the temp sensors are a little more tricky. IAT is ...
