[@DrBernard989]

Having used an Arduino mega in some initial prototypes , interference causing the Arduino to hang was a persistent issue unless it was fully enclosed in a metal housing and any external connections used shielded cables. Being anywhere near a VFD for an induction motor meant issues were certain, for example. Great video thanks.

[@TykeMison_]

Yep when the arduino reboot issue happened my immediate thought was RFI/EMI! Motors make a ton of noise from the coils/ignition

[@MattExzy]

Error recovery might be possible using the 2560's watchdog timer.. if an operation takes too long, maybe halt interrupts and reset.. buuuut. I think the Arduino bootloader itself hogs the timer in some ways. I think a shiny metal box is called for, definitely.

[@Sevalecan]

My first question would be are we thinking conducted or radiated emissions? There's no VFD on this car and the electronics are primarily the arduino itself. The main culprit could be the ignition circuit in that case, I'm guessing. That's a high voltage switching situation which could generate large EMI spikes. Second, it didn't sound like the arduino rebooted. It sounded like the ignition jumped out of time(at least to me). But doesn't the crank wheel have a tooth that indicates 0 degrees? So maybe the processor did mess up. But I still wonder if a small radiated emission might've messed up timing somewhere. Faraday cages and shielded cables can do their job when used correctly, just seems excessive to say it's required. I would suggest making sure things like the ignition switching are separated and that the emission sources aren't right next to the arduino. But I could be wrong, maybe it is that sensitive. Not impressed if so. This of course all assumes the firmware on the Arduino has no issues with throughput and is not missing samples. Always a challenge doing real-time processing

For your speedometer, get a bicycle one! They sell them for like $12 at Walmart. You attach the magnet to the inside of the wheel, attach the sensor in the wheel well close enough for it to read it, enter the tire diameter in the computer and you get a speed that gets updated every revolution, instead of a choppy GPS signal!

[@SalveMonesvol]

Or, you can attach 2 sensors and imput 1/2 the diameter to get more frequent readings.

[@thefirstmissinglink]

Put it on the axle next to the transmission that way you don't risk damaging it from dirt and road hazards. You would still enter the diameter of the wheel the same way.

[@GoPaintman]

Supercharger boost formula is pretty simple. It’s the ((air the supercharger makes in 1 rotation / the engine air) * 14.7)-14.7. The air that the sc makes in 1 rotation is it’s capacity * pulley ratio. You can make an excel sheet with different pulley ratios to see what the sc will make.

The Arduino layout is notoriously prone to emi and transients. And a spark plug is noisy emi event. I'd put ferrites and shielding on everything, and maybe look into getting an industrial hardened version. Also maybe a resistor plug to limit noise.

[@racingjason]

Facts. I use arduinos for Halloween props and you can't keep them close or they will trigger each other.

[@lazar2175]

Yeah, my homemade CNC is running off of the Arduino GRBL shield. It kept freaking out and destroying my projects randomly until I figured out it didn't like being around large brushless motors and the power supply. The problem finally stopped once I put the Arduino into a metal project box, attached it to an independent power supply and moved it from the SMPS. So I think it would be logical to make an aluminum enclosure, add ferrites and maybe even a voltage regulator for Arduino power. I'm not quite sure what's powering his Arduino right now, but they are rather sensitive to voltage.

[@nerd1000ify]

I was enough of a fool to actually try to use one to drive an ignition system on a model engine. Even with shielded ignition cable and careful grounding it never worked. Pretty sure the voltage transients cooked the inputs on the chip.

based on my personal experience from MAP based tuning, I recommend you try hitting some partial throttle points (88 and 80 kpa). That will help stabilize your AFRs during WOT pulls so you get more consistent and smoother acceleration. Drops in atmospheric conditions will have your AFRs all over the place.

[@shenaniganswhatsoever363]

I love the series, really look forward to new episodes. I dont mean to sound like a broken record, but the cvt is not efficiently giving you power on 3rd gear take-off. Its designed to handle something like the ratio of 2nd gear at most, with that much weight. That is why it undershifts (overrevs,) then overshifts (underrevs.) A bigger torque converter with a bigger diameter secondary could help greatly. Or just a standard or centrifugal clutch, with proper gearing. Sorry for the long winded reply, thanks for the great content!

[@2flyabove]

Excellent recommendation.

[@Timmy6216]

I have serious respect for your engineering mostly because of this little detail that you are utilizing the OEM transmission which so many people tend to not and I don't understand why it's just another gearbox to change more gear ratios to help you get the vehicle from point A to point B.

[@tiporari]

Good progress. I suppose some power input shielding on the Arduino, some opto isolation on inputs and outputs, and perhaps some RF shielding on the PCB would preclude future corruption. Not exactly industrial grade electronics there, but easy enough to rectify the obvious weak points. Cable routing matters too. CANBUS uses differential signaling for a reason.

[@theonewithin609]

Not required at all. You might be best to look into what a Speeduino is before making comment.

What a treat. Coffee is made and wife brought me biscuits. Happy me.

[@X7rocks]

Just an idea for the cvt. A stiffer spring can help kill that high end dip in power to come in a little bit later, and the guides on the rear pulley will help dictate how much of a drop in rpm can occur when the cvt is upshifting. A smoother angle can also help control the drop in rpms so you don't stay out the engines peak range.

[@robotcantina8957]

Thanks ! I'm holding off on tuning the CVT until after the supercharger. The torque curve is likely to change drastically.

[@tblosser8921]

Yes tighten the rear spring for sure looking at your data log it looked like it was pulling at about 3300 and with your intake and exhaust I think (just from my experience with hemi 212s) it would do a lot better closer to 3800 and would cut down on belt slip which I believe is what is causing the choppy rpm reading

[@shenaniganswhatsoever363]

Need a bigger secondary, hands down. I've toyed with springs and ramps. Just band-aids for the real problem. Much bigger setup needed. I'm gonna find a broken record for my avatar picture lol.

[@X7rocks]

@@shenaniganswhatsoever363 bigger secondaries would help with pulling a bigger sprocket. But if the angle isn't smoother to maybe a 45 degree angle or so the rpm drop will still be severe. But still a very good mod to think of when using overdrive pulleys

[@shenaniganswhatsoever363]

@@X7rocks maybe on paper, but the secondary size is a huge factor. I've put alot of those torque converters on go-karts. Hands down the biggest performance improvement is choosing the right gearing. I've played with secondary springs and ramps. Also messed with primary engagement and weights. The only way to truly get them right is to not over-gear them. So if you wanna go 55 mph you will need a snowmobile sized torque converter. Then play with springs and helix ramps. EDIT: And primary weights/springs! It all needs to be tuned together! They make a comet 94c primary with a 1 inch shaft for 4-strokes. I would recommend an arctic cat secondary with a yellow or red spring. Get helix's 44 through 55 to play with.
