Re: VSS digital input
The stm32 internal pullup/pulldown should be on the order of 30-50k ohms. That's not your problem.

Re: proteus iat and clt sensor drops temp when power apply
Calibrate while the board is supplied with 12v. It doesn't know that the sensors don't have an accurate 5v pullup when the 12v ignition supply isn't active, so it reads wrong. When powered over USB, the 5v rail is really more like 4.6 volts due to the diode drop in the protection circuitry.

Re: Injector and Ignition Pin Mapping
As is, that message is more confusing than no message at all.
I'd write something like "wire each output to the corresponding cylinder number, rusEFI handles firing order"

“As numbered from the end with pulleys” isn’t always true on V engines. Some MFG use various other schemes, including your BMW V12.

you don't want a FET at all, you want an IGBT designed for ignition coil applicationsmtmotorsport wrote: ↑Fri Jul 07, 2023 8:58 pmThe actual FET you use for ignition coil control is very important. It needs to have a very high avalanche voltage (350v+), very fast turn off time at moderate current (5-10amps), and very low RDSon.

Re: VW Type 1 "Single port" injection
Run it in batch mode, but with the fuel injector flow rate set to half what it actually is. The fuel injector flow rate parameter is actually "injector flow per cylinder", not "injector flow per injector", but those usually align to be the same thing.

The first step is to add correction factors for all important analog inputs: ..... Instead of a sensor, you can connect a voltage generator there and do it with it - it doesn't matter how it's done.

Re: ECU accuracy
This means that we should be able to correct the readings of these input data so that the readings in the ECU correspond to the real data. And this proves to us that a single correction for everything, for example, vREF for all, is garbage! This is a bold claim to pull out of nowhere on your third ...

Re: Vibration vibro test
Yes, that glue is for vibration resistance. The "vibration problem" of electronics is not something you're likely to be able to find with a sawzall because the frequency isn't high enough. To try and get those caps to fail, you'd have to vibrate at a frequency that excites the mechanical r...

Re: Discrete components VR decoder with zero firmware code
Also, that edited schematic doesn't actually fix it: The problem is with the clamp diodes, not the opamp inputs. If you delete the diodes the opamps are less protected, but the common mode input range is expanded. Edit: just move the diodes to the inputs of the first opamp, instead of prior to the 1...

Re: Discrete components VR decoder with zero firmware code
You can also pull this off by capacitively coupling the sensor inputs, then doing whatever you want with the DC offset.
Ground one pin, ground the other pin, doesn't matter, it'll work.

Re: Gen 4 LS - no crank trigger
Shared sensors grounds are generally fine, not enough current there to cause an offset.

Re: Gen 4 LS - no crank trigger
Ah hah, that'll do it! Our input voltage threshold is relatively low (2 volts or something? don't remember exactly), so even a "little bit" of ground offset can trip things up.

Re: Gen 4 LS - no crank trigger
I'd make sure that the ground wire is going to the ECU's sensor ground, and isn't connected to chassis/engine somehow. An easy test is to unplug the connectors from the ECU, then measure ohms between the sensor's ground pin and the block.

Re: Gen 4 LS - no crank trigger
Has this crankshaft/sensor combination run an engine before?
I ask because the 24x vs 58x trigger wheels need a different sensor (24x black sensor, 58x grey sensor). If they're mismatched then you'll get a crappy signal or no signal at all.

Proteus has internal pullups on the digital inputs already.

look at how the gap ratios are 1.0, 2.1, 0.84, 0.54, 1.0
For N-M wheel, gap ratios expected are 1.0, (M + 1), (1 / (M + 1)), 1.0
