Are you saying that RusEFi makes a TDC compression cycle flag per 720° arbitrarily?

without a cam sensor, yes

That green mark is the TDC mark as generated by the ECU - it's not a sensor. It certainly seem so with respect to the phase change between the missing tooth and the green trace pulse as a function of the "Trigger angle advance" variable, but if it were a true TDC label or flag, it should'v...

EV1 and EV6, both long, are compatible. My Volvo came with EV1 style (fat) injectors, and now I have the skinny EV6 type with no other changes.

After a little more research on these weird one-off Porsche injectors, I don't think they'll work with any rusEFI ECU today. They require some weird control to handle, so it's probably worth switching to newer units.

But if I change to another injector, it likely won't have the same flow rates, etc., so would complicate my ass-backward method I'm using now to build tables. If you're using rusEFI, it should be an easy change to switch injectors. Also, I'm not all that familiar with the different injectors availa...

Ooops .... I was wrong, they are actually 4.6 ohms. They are a Bosch 280 150 803 and I think they are from a Porsche 944 Turbo.

Are you opposed to replacing them with more modern high impedance ev1 injectors? Looks like the standard Bosch geometry, so anything else should fit.

For a test project, I was planning to use an engine with Bosch 4.5 ohm injectors. But I see the microRusEFI doesn't have enough drive current to do this, so am now planning my first test project with the Proteus instead. I assume the Proteus should be able to drive into a 4.5 ohm injector? 4.5 ohms...

Freewheeling diodes are required when you want slow turn-off, like if you're going to PWM a solenoid (VVT, idle, etc). Fuel injectors you specifically want to turn off quickly, which means they need active clamping instead. All outputs on proteus/microRusEfi/etc have active clamping at 40-60 volts, ...

Thanks for answer, I'm very new on STM32, how I build bootloader? have a look in that script - it'll build the bootloader before building firmware, then combine them in to a single bin image Ok but the board of the zip file works find? or it's better the kicad board, I ask because I all ready order...

Hi, I try to compile firmware and have a error, do you know what I'm doing wrong? It's looking for the bootloader to be built first, as the bootloader gets cooked in to the main firmware image. The most "bulletproof" way to build it is to use the build_wideband.sh script, found in the f0_...

1. Не смог найти где выставить зависимость время заряда катушки зажигания от напряжения в борт сети. Andrey has a created an issue on GH to track it: https://github.com/rusefi/rusefi/issues/3099 2.

Injured the engine a bit at the last race, so we rebuild it to find that we'd broken 3 top piston rings :shock: https://www.youtube.com/watch?v=9hL0jGzNt3U Engine is now rebuilt and back in the car, so here's the current tune+log: https://rusefi.com/online/view.php?msq=607 https://rusefi.com/online/...

Does the ecu give you any way to change adjust the TB positions independently? That would be a great feature if it doesn't...syncing the TBs is really the best way to sort this kind of issue before going to fuel tables to deal with the affects of the issue. It doesn't now, but I think he's going to...

and ISP752T.... for High-Side switch

lower current, 1.3A vs 2A, but yes

specs look very similar to the VNLD5160, should work just fine

BM2LC105FJ-C is replacement for VNLD5160

can you please post pinouts for both? i recall there is an opinion that pinouts are different?

he's right, there are two pinout options for that family of chip from ROHM, and it looks like the BM2LC105FJ-C does indeed match

On another note, thinking about a crazy idea, this issue of having 2 separate banks, do you see an opportunity to develop a dual MAP, dual bank configuration that would allow us to assign injectors to a bank and then assign a wideband to each bank. The Proteus has more inputs to allow this just won...

OK. I reversed the top and bottom pins on the TPS connector. Now it works. However the 10K resistor is too high for a proper pull-up for the KIA sensor.

@Andrey maybe this should be updated to the wiki?

I think the 10k should be removed if you have an analog TPS

Trailing coils have a special color in rusEFI console Engine Sniffer

they should probably get interleaved with the actual coils, ie

coil 1
trailing 1
coil 2
trailing 2

Yeah.

What kind of pedal are you using, and is it wired correctly? I believe both harnesses were shipped with baby Toyota pedal sensors https://github.com/rusefi/rusefi/wiki/OEM-Docs/Bmw/1998_750_e38/proteus_0.2/Proteus_ready_for_M73.jpg see https://github.com/rusefi/rusefi/wiki/HOWTO-M73-v12-on-Proteus ...

Just a side note I realized Andrey was correct and the 2 harnesses I had from him were different. One for V2 and one for V4. So I plugged the V2 board into the V2 harness. I powered Pin 23, 18, and grounded 19. I get similar results where the ETBs hum but no movement. In this case though there seem...

Hey everyone I'm back at it. I'm looking at the TPS issue now, I'll trace the wire back to the v4 make sure its' connected. Andrey wired the ETBs so I'm sure they should be connected. I'm guessing both TPS1's from both sides of the V12 are connected in parallel so TPS1 of ETB1 is connected to TPS1 ...

No, that's K-Jetronic. LH-Jetronic = airmass hotwire. K-jetronic = mechanical MAF (!) that actuates valves directly that control fuel flow.

PID looks overtuned, but it is tracking roughly. Here's with the scales adjusted so they line up correctly (even though one channel is 10x):

The pcb in master has some minor changes (swapping to use more of the same component) that have never been fabricated. If you would like to fabricate a board, please use the latest release (0.6) as those files are proven. If you really want to use kicad, the problem in master is that the copper pour...

With parts shortage what is the complete list of MCU options official firmware would run on? Matt does Proteus require 2MB of flash or would it work with just 1MB? Is the official build using 180MHz or 168MHz? Ideally let's document on https://github.com/rusefi/rusefi/wiki/Chip-Shortage-Parts-Inter...

Add a bunch of leaded solder over the top, partly to lower the melting point and partly for the mass so it stays hot. Hot air, lift the old chip. Solder wick off the old solder. Fresh paste. Drop new chip on. Tack a few pins with the iron. Hot air to reflow the new chip. Clean up any shorts with flu...

http://himeshp.blogspot.com/2018/08/fast-boot-with-raspberry-pi.html says total boot time 5 seconds. Do we need 17 seconds to launch java and connect to rusEFI?

that has no gui

Sorry, I should say "not possible without writing the dash in C++ and running it in place of init"
