Re: Marquis de Sad - 1997 Mercury Grand Marquis
Matthew figured out why the VSS wasn't working at low speeds - The MAX9924 goes into a more sensitive mode if there has been more than 85ms since the last output, which in my case works out to about 3.4 MPH. https://github.com/rusefi/rusefi/issues/4117#issuecomment-2050869491 There is another VR dec...

Re: Marquis de Sad - 1997 Mercury Grand Marquis
Some VSS scope captures at low speed for reference. There's a little EMI noise, not sure if that's what's causing the issues or not.

Re: Marquis de Sad - 1997 Mercury Grand Marquis
I got 34 automatically-shifting miles in today. The VSS is a problem, but otherwise it's drama-free. I reckon maybe the issue I am seeing with the VSS is probably the same as Andrey was having with ISS. The next step is to throw a scope on it to see if I'm getting a signal that ought to be usable.

Re: Marquis de Sad - 1997 Mercury Grand Marquis
I woke up this morning with the goal of making the transmission shift automatically. I didn't reach that goal, but I'm really close. Remaining problems: 1. I forgot to reconfigure my shift solenoids after my configuration got wiped. (I think this was due to changing FLASH_DATA_VERSION, but IDK how t...

Re: Marquis de Sad - 1997 Mercury Grand Marquis
A multimeter in DC mode, which I assume does basically the same thing as a RC circuit would, shows 9.8-11.2 volts. It doesn't seem to vary in a way that makes sense to me, it seems pretty random. I feel like ignoring for now, controlling it with ordinary PWM seems to work fairly well. I just thought...

Re: Marquis de Sad - 1997 Mercury Grand Marquis
I need help understanding electronics again. The pressure control solenoid seems to have PWM control targeting some current, but the duty cycle doesn't change significantly, only the frequency. This goes against my understanding. Does varying the frequency to a solenoid change its output force? KOEO...

His spirit marches on.
The 10K resistor has been quite successful. There's no noise when parked. When you start moving there's some noisy nonsense but it settles out quickly and behaves as it should.

I have acquired a 1997 Mercury Grand Marquis for a transmission test subject. It's got a 4R70W, which ought to be pretty easy to control. I bought this thing from a kid in Oklahoma City on January 20. I failed to sufficiently "buyer beware" and only gave the title a passing glance. As it t...

Re: ELI5 truck diesel engines
Short answer is "it varies"
Older stuff is purely mechanical, newer stuff has computer pressure control and injector firing.
Most new injectors are high-ish voltage piezo, and are fired multiple times per injection cycle.

Re: Hellen Ford Taurus SHO
In my head, the way to do this is to make an ELM327 Hellen module, and let it do the heavy lifting. Interfacing with the ELM327's AT firmware should be easier than implementing n weird serial protocols.

Re: Transmission Control logic
I need some ideas for generalizing the configuration interface for transmission control solenoids. Currently I'm looking at the GM 4LXX series - 4L60E, 4L65E, 4L70E, 4L80E, 4L85E. Control on these transmissions has a lot in common, but also quite a few differences. Currently I'm focusing on the 4L60...

Re: Transmission Control logic
There are still a few things I don't know about how the TCC is controlled. The service manual states, regarding the 4-3 downshift: The PCM de-energizes the TCC solenoid valve, and operates the duty cycle of the TCC PWM solenoid valve to release the converter clutch for a smooth disengagement, prior ...

I've used Dirtypcbs quite a bit, but I found that this board was big enough that it was cheaper from JLC. At least when I did it; pricing may have changed.

Re: V12 M73 to Audi trans, with Proteus in Lamborghini Replicas
Hook up your air compressor to the spark plug hole and listen for the hissing. That will tell you if it's the exhaust valve, intake valve, rings, or head gasket. 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.
