Also I understand D1 gets hot. Perhaps that would have some thermal via's. Yes - D1 is also dissipating maybe 1/10 watt, but it has almost no thermal conduction to the case, and almost all the conduction it has is to the already-hot Q1. Probably a better plan to investigate using a pfet instead, si...

Q1 doesn't switch. The tle8888 is using Q1 as an external linear regulator to get the dissipation out of the tle8888 itself, then doing the precise 6v -> 5v regulation internally. Per the tle8888 datasheet, page 58: A linear pre-regulator with an external logic level power MOSFET is implemented to k...

Stm32 does. 45-50c internal stm32 temperature is consistent with what I've seen running on 12v, sitting on carpet with only the bottom half of the case. My board pulls just shy of 300mA. So Q1 is dissipating (12v-6v) * 300mA = 1.8W. The 8888 should be dissipating around 0.3 watt in its regulator, pl...

I suppose I should provide an update on this car: July 17 I took the car to a track day, running on Frankenso. Other than identifying a (now fixed) trigger performance bug, the ECU did fine. The car had some pretty serious windshield fogging problems since it was raining, but that wasn't rusEfi's fa...

This got posted on Facebook, but not in this thread! microRusefi has now run an engine! Last week I successfully wired and started my Volvo b230 on microRusefi serial number 1. https://www.youtube.com/watch?v=YD1suLdczv8 Since the engine was already running on Frankenso, the tune ported over with al...

I've left mine running for several days with the trigger simulator running the whole time without issue! Powered from +12v.

Internal ADC is interesting - it's also not bosch, so documentation is far easier to find, and it's far easier to actually buy one (Mouser has them in stock). And they're cheaper: $6.55 in single quantities.

I think trying to run those extra 30 volts is probably unnecessary. I bet it will work just fine at 72v, though the injectors may open a tiny bit slower. From the link with scope traces, the part circled is the only part that would change: https://imgur.com/laM5r6s.png The slope would be around 25% ...

When you get the Frankenso pre made, can you see red dots of glue under the 0805s on the underside. I hear that 0603 and smaller will stay on the underside without glue with a 2 oven process - oven solder bottom side parts and re oven for the top side parts -, due to the solder surface tension, but...

First, how well has tuning worked with rusefi from adding a turbo to a vehicle that originally was N/A? A few of us now have run NA and turbo on the same engine with rusEfi. I've done it on my two Volvos (one NA, one turbo), and a friend of mine did it on his NB Miata. Ultimately tuning with a turb...

So for analog sensors, I count: 4x TPS (2 per ETB) 2x MAP 2x oil temperature 1x intake air temperature 2x "pedal" input 2x wideband Which is a count of 13, which could maybe fit on Frankenso with some rewiring, but might be more hassle than its worth. If you could temporarily live with a single oil ...

Hey, more people with LS engines in the PNW! I have a 1993 Volvo 240 with an LS swap that I'll convert to rusEfi at some point (the car was running rusEfi when it had a turbo 4 cyl). I'm up in Kirkland, and noxz on the forum is in Seattle. I could be convinced to come to the rusEfi party if it's on ...

I had a chance to look at the OEM circuit, and it looks like the CY220 uses a very similar architecture as the MC33816 or PT2000. There's really only one architecture out there for running DI injectors, and they both implement it. Because peak-and-hold injector drivers like these run closed-loop con...

I am very interested how to tune Injection Phase ??? For engines like ours, injection phase doesn't really matter much. You will probably get slightly better emissions, cold start, and idle smoothness if you inject against a closed valve so the fuel vaporizes fully by the time the valve opens. I wa...

I've heard not great things about Innovate's reliability. A few of us here have had good luck with AEM's wideband O2 sensors and gauges. They make both standalone controllers (no gauge) and integrated gauge+controllers. The gauges include an analog output that you can wire to the ECU so it knows the...

But what i will make with sensors? More precisely, with a count of them, because i have more sensors, than analog inputs on Frankenso What's the full list of sensors you plan to run on your bike? The second - is CAN-bus. Frankenso can recieve data from sensors by CAN-bus using other unit, which wil...

In my opinion... russian has wrong / low / undersized starting battery .. (or wrong starter, or wrong starter wiring - high transient resistance) If battery voltage drops below 10V when we cranking .. then we have problem ... :roll: "input voltage" pulses and "many in-chip voltage stabilisers" don'...

How low and for how long will depend on the engine, battery, vehicle wiring, etc, but it certainly wouldn't help if there was a dubious connection somewhere.

12V-switched is where most of the bulk caps are. We should have a PMOSFET to prevent back flow during cranking when the 12V will drop. Currently we loose the bulk caps during this cranking time. True - that will help with very brief dips, maybe 1ms at most. I think the actual issue with dropout dur...

chip which is desired for around 80V can drive higher by changing the resistor divider. But there are still other limits. And those other limitations are significant. To be able to turn on the high side nfets, you have to get the gate above the supply voltage, which means the gate driver needs to b...

This board was soldered with a stencil, paste, and reflow oven. They came out pretty perfect: https://i.imgur.com/2x4iNBg.jpg (This is the STM32, but the 8888 looked similar. I think this is a pic of the board that Russian has, if not, his is the other identical one I assembled at the same time) I o...

Let's start with the first rule of electronics diagnosis: Thou Shalt Check Voltages Apply 12v to the 12v pin, then check the voltage at: Anode of diode D1 (end towards connector): expected ~12v Cathode of diode D1 (end towards Q1/away from connector): expected ~11.45v Pin 2 of Q1 (large tab, toward ...

The tricore and GTM can do some cool stuff. However, I don't think it's worth our time to port rusefi to TriCore. There isn't a real problem with the stm32. The GTM is pretty cool, but we don't really need it-our existing software scheduler works just fine. Likewise, 5v I/O would be pretty neat, but...

Why not just drive it from the MCU? The STM32 has one or two MCO (master clock out) pin(s) that output a clock divided off of the core clock, which would work great for this application.

- Try to find out as much as possible about the injectors as it seems the MC33816 might not be able to generate sufficiently high voltage? - TBC If the injectors are solenoid (not piezo), the mc33816 can probably drive the injectors. Noxz will eventually be testing with modern Denso diesel injector...

I understand it's lite in terms of C compiler projects, which have many useful checks and balances. However it's bloated compared to bare metal hand written assembly. Absolutely - but I think that's a feature, not a bug. I'd have a hard time beating GCC at most of the stuff our firmware does. I cou...

(oops - I was typing this response when you replied - but we're on the same page here) Could HWA also be used as a kind of GRC add-on? Nope - something GRC-like is very high level, and HWA (or ChibiOS/HAL that we use) are for the very lowest level of hardware interaction. but the idea of these block...

Welcome! That car is fantastic. It'd be a shame if you ruined it with rusEfi... :P I've seen some pretty convincing fake Weber DCOE carbs that covertly contain a pair of fuel injectors... I think Jenvey in the UK makes some, but they're something like 600 GBP each (2 cylinders worth - so you'd need ...

In that case, it probably isn't working properly. Can you set the debug mode to CJ125, and share a datalog?

oh, that's what it's for! do they need tape for a suction cup to work? Yep, the pick-n-place machine uses vacuum and a little rubber suction cuppy thing to hold on to components. So anything that doesn't have a relatively uniform flat top needs a piece of tape or something. Likewise, the vertical U...
