For wiring, the flex sensor is 12v, Gnd and signal. Does the signal circuit need anything external on the H64 that uses the digital input?

If there's an internal pullup, then no, it doesn't need anything else.

Yes, this is certainly in the plan. Probably to be implemented via lua, since it requires huge flexibility to actually be useful.

your tune is pretty crazy, what is going on here?
At 38 IAT and 65 CLT, the total fuel multiplier is something like 2.3. What's up with that?

Dude, you're hitting 100% injector duty cycle. If we hit 100% duty, we cut fuel.
Get bigger injectors, reduce boost, add fuel pressure, etc.

At the moment Proteus are often shipped without baro sensor due to chip shortage drama.

You can, however, of course install an external baro sensor. Even just leaving a second MAP sensor flapping in the breeze (or connected between filter and throttle) would work fine.

You have a cam sensor selected. Please set it to none.

HW limitation is not RPM but RPM*tooth count. We are confident that we can do 11000 rpm * 60 tooth trigger

11k with 60 teeth is probably pushing it. A safer place to be is a 24 or 36 tooth wheel, for example, a 24t at 12k is similar to a 60t at only 4800 rpm.

His board is configured for magical new VR interface.

Jimmy's is too, so we've run two engines on it now!

Let's try to stay on topic, this thread is specifically about the fact that we have two slightly different different configurations in the firmware for 60-2 wheels.

..in real life... is difference a half tooth on offset between HALL and VR... on 60-2 is 3deg., on 30-1 is 6deg. etc. I'm less worried about that. Checking offset with a timing light on a running engine is a required step for any new setup, except for extremely known configurations (GM LS 24x for e...

There should be no difference (that we care about) between hall and VR. We should be only looking at rising edges, which will be in the same place between hall and VR. All we care about is that there are rising edges at even intervals, then one gap between rising edges that's 3x the length of every ...

I compared the images of 60-2 and 60-2 VW from our wiki: https://github.com/rusefi/rusefi/wiki/All-Supported-Triggers This is just overlaying then differencing in photoshop: image.png The differences between the 60-2 WV option and the 60-2 option are: Falling edge during the missing tooth in a diffe...

Does anyone have the inverted version of the wheel with the gap being a solid block?

yes, my volvo is like that. They use the edge of the flywheel, with 58 notches cut in it.

supercharger solenoid?

swap in the plentiful and cheap M111 Kompressor engine, but with a turbo

I don't think he plans to run a supercharger.

I don't use official binaries because I modify the Haltech can communication because some of the channels proteus send I send them by another module (like Wheel speed). I made a custom module for 4 VR speed sensors and send those values over can bus to my datalogger display. And if this module and ...

Josh can you please check supercharger clutch solenoid resistance?

that's about https://github.com/rusefi/hellen128merc-issues/issues/10

Jimmy says about 3.4 ohms

mk e, you mentioned you ran the pressure down to 1 bar before the flow calculations started to fetch up in the ECU. Does that imply your ECU is using fuel pressure as one of it's inputs? Mind you, he's not using rusEFI. rusEFI does support a fuel pressure input for automatic flow compensation, thou...

Did you really build proteus firmware? You mention F407, but the proteus firmware image requires F427/9 for the extra memory.

First step in diagnosis: let's get the warnings under control. image.png CUSTOM_OBD_LOW_FREQUENCY CUSTOM_VVT_MODE_NOT_SELECTED CUSTOM_OBD_SKIPPED_SPARK CUSTOM_OBD_SKIPPED_FUEL With so many happening, it's hard to tell which happens when. Please either disable VVT input, or pick a vvt mode so that on...

Let's start with collecting data: can we grab a trigger log in Tunerstudio at idle and 4000 rpm?

It would be nice if pin selection drop-down list in tuner studio displays only pins that are actually available for the feature, e.g. vss input can only be assigned to pins of a certain category. Moreover, AFAIK, can, usart or spi (if at all available), is assigned to couples or groups of pins, i.e...

Higher pressure is fine. If anything it improves the spray pattern (higher pressure -> finer mist due to more turbulence).

Flow is proportional to the square root of pressure. Doubling pressure increases flow by a factor of 1.41 ( aka sqrt(2)). Quadrupling pressure doubles flow.

The Oil issue being my bigger issue because it looks like hell and smells like hell. The problem popped out of no where a week after I started testing before I found the bad cyls.

This almost sounds like a stuck ring.

If it's the rings, there's all kinds of potions people put in their cylinders to try to free up the rings. Sometimes they even work. Unless it's a broken ring (been there, done that), perhaps the most effective potion is horsepower. A friend of mine fixed an oil consumption problem on his miata wit...

Is it worth getting the car together enough to go for a drive (even if down a cylinder and the injector unplugged) to try and get some heat and pressure in the rings?

rusefi.com/online also accepts logs

Can you take a log of cranking? If "fuel map" is injecting no fuel, it probably means something else is wrong.

Interesting. I'm using rail-to-rail LM324 opamps: 511-LMV324IDT https://no.mouser.com/ProductDetail/STMicroelectronics/LMV324IDT?qs=%2Fha2pyFaduibZAP9%252B5%252BCY2oSbPgWZew9Bgw6Sz79D3I8LujhD5rsqg%3D%3D Those are not as rail-to-rail as you think they are. They can only manage about 50mv to 4.5v out...

When I first gave it a go yesterday, I couldn't get the TBs to work. Calibrated TPS just fine, but wouldn't run the PID-cal routine. From neutral to closed, they would respons just fine, but as soon as I tried to get them open past neutral point, the TPS gauge would oscillate between real value and...

To expand: if you have a cam sensor, it will start on wasted spark, then "fix" the engine phase with the extra knowledge from the cam sensor.
