;) open source design https://github.com/corygrant/DingoPDM_HW Im looking at getting a run of these assembled to have a play around with... any interest if i get a few extra? Will probably do the standard 8 output and the 4 higher current output 'max' versions. Not sure on timing as i would prefer t...

Got a question for the smart people... Why are lowside outputs 13,14,15 & 16 the only ones with flyback diodes build in? Im having some issues getting my VVT solenoids working at high PWM frequencies and I think it might need a flyback diode to fix the issue (well thats what im going to try next...

I do 24hr lemons racing and have been looking for option to get a live video stream and telemetry from the car. Came across this fpv drone software that uses rpi hardware and combines video and telemetry into a single 2.4/5.8g wireless link. Looks pretty promising assuming the mavlink data stream ca...

Thanks Andrey... Ive tried a few times but this might be excuse I need to get deep enough to understand the firmware code.

I have a new proteus 0.7 for the race car and looking forward to using the sd card logging. As i understand it the card doesnt log if theres a usb connection to the ecu. Is there any way to change this behaviour? I have a rpi permanently connected running tuner studio to display the dash. This also ...

Turn off "Print verbose trigger sync to console", though. I bet $1 that's the issue. I owe you a dollar. Its now smashing the limiter at 5700 with no trigger errors. ETB works quicker than i was expecting so can probably adjust that a bit higher. Off topic but can you recommend a windows ...

Probably unsurprisingly the GM high feature V6 bottom end seems pretty similar to the ls v8s. Its got exactly the same arrangement except the sensor is on the opposite side to the starter.

The v6 even has piston oil squirters.... its just crying out of 15 lbs of boost once the ecu is sorted.

The crank input is currently from the factory hall effect sensor connected on the digital 3 input. The trigger wheel is located on the crank between the 4th and 5th main bearings. Modifying it to remove teeth would be messy and difficult. I will try the suggestions over the weekend and let you know ...

Files links below. I didn't save the trigger log but will grab it in the next couple of days.

So I'm assuming this is a trigger decoding issue in the firmware then? I am just a little offended by your assumption. We know for sure that we handle high RPM at 60/2 trigger just fine if we get a happy signal. I don't mean this as an accusation or a criticism of what you have created... just tryi...

For simplicity of configuration, try turning off all cam sensing stuff first. Disable the cam inputs, set the cam modes to NONE. Set ignition to wasted spark, it should run totally fine that way. That fixed most of the issue. Its still having issues above above 5500 but is clean below that which is...

I replaced the VR crank sensor with the original hall effect sensor and connected it to one of the digital inputs. I also seperated the cam sensor wiring from the rest of the harness but am still having the same issues with it missing crank teeth above 2.5k RPM. It doesn't appear the problem is rela...

i have used the shielded twin core from the factory harness although i did have to join a couple of pieces. Will 0.5mm2 screened industrial 'dekoron' cable work ok? it the only stuff i think i can find locally at short notice. I think it only has a foil screen though. The vr sensor is from a vz comm...

Something else I probably should mention is that this particular engine was originally running a hall effect crank sensor. It is very close to the exhaust so broke when I was taking it out so I ended up replacing it with a VR sensor from an earlier model spare engine I have. I assumed that trigger w...

Still starting to lose teeth from 2.5k rpm then going batshit at 5k. With wasted spark on it recovers after the revs drop again but runs poorly after that.

This is 2.5k RPM.

Went through the trigger setup again but still not looking like it should. I think I had it the same previously but had changed it in my effort to try different things. fixed trigger.JPG tune file https://rusefi.com/online/view.php?msq=959 log with individual spark [*] https://rusefi.com/online/view...

So my engine is running, but not well and i have an issue where the engine loses sync at at revs and shuts down. When it cuts out I'm pretty sure the ECU thinks the crank is a full revolution off its actual position as it continues to fire the ignition and injectors just on the wrong cycle. Generall...

thanks gents will wire in series and see what happens

Its a relay to power the WBO2 sensor heater.

The existing outputs are used for
6 x injectors
2 x vvt solenoids
2 x fans
main relay
starter relay
smart alt control
intake manifold solenoid
fuel pump
check engine light

I could probably repurpose the check engine or consolidate the fans i guess

Just realised these are logic level outputs so hence the reason it doesnt work!

I have a car with a split fuel tank and 2 separate level sensors. I want to create a custom channel that calculates the total based on the two signals but am struggling to find where to define a custom analog signal... What am I missing?

I have used up all the low side outputs so want to use a spare ign output to drive a relay.

Will this work and do these function as high side outputs?

Finally installed my v0.3 in my latest track car (Holden VE commodore with the LEO Alloytec HFV6). Car starts and runs... yay! There are a few errors on the online pinout diagram for the 23pin connector I found in the process of getting it working. The main one is that pin 14 is listed as a gnd but ...

I have created an unvented version and sent all the files to Andrey to drop into github.

I have kept the LED holes with thought of adding printed light pipes.

I had a go at a 3D printed case in fusion 360. Obviously not waterproof but I figured it would be better to include ventilation as I assume it will run warm. I will share the model files and stl when i get a chance. IMG_20200910_191952.jpg IMG_20200910_192004.jpg IMG_20200910_194904.jpg IMG_20200910...

Anyone have an STL for a 3d printed case for this?

Interested in getting in on this... Have sent you a PM mck1117.

Im in australia.

Lots of really great progress... Wish I had some time to play along at home!

looks great... my reflow oven is on standby ready for a successful prototype.

I though I had the path set as a project specific variable and have been saving everything in the one folder but maybe not properly... will research what I have done wrong... I haven't contacted infineon about the eval board but probably should. L1 is based on the recommended starting point for indu...
