Hello,

did you try the EGT input ? If yes, did it work ?

Thanks,
Not yet. But I tried similar chip on other project - works just fine.

But, please note that stock Subaru engines have unknown EGT sensor... Actually I'm not sure that Subaru EGT sensors are termocouples.

When you say "tested using console" was there a an actual Subaru IAC hooked up?
Yes. It was connected. FW was running self-simulation and blipidle command was used for idle valve testing.

Hi. Sorry I had no chance to check my settings in TS. Spend whole weekend trying to create ini file for my own board. No luck. Also stuck with some strange bug with slow ADC.

Re: Looking for a solution for the Subaru EG33

Regarding voltage should I be getting 3.3volts on either pin? With the PWM set at 50% I'd expect 6v connected to a 12volt source. Looking at the schematic for Frankenso 0.4 the low side drivers output 5volts. So maybe 3.3volts is what I should expect and its not enough to drive the IAC? Low side ou...

A screenshot of the idle settings in TS would be helpful if possible.
Ok. I'll do. Previously I did all configuration by code/defaults modification. I run TS for few times only. Time to learn new tricks.

This is how IAC is connected to ECU on EJ20G. I don't think think they invented something new for EG33. Actually this is the same.

Re: Looking for a solution for the Subaru EG33

I connected center pin to +12 and drive open and close ends using PWM. I was able to rotate IAC from fully closed to fully opened by changing balance of duty cycles. This is what implemented now for two-wire IAC.

Re: MicroRusEFI, not recognised by computer?

as i cant see anything else on that circuit that could pull the signal low, is it safe to assume the MCU is dead? On MRE 0.5.0 TLE8888's WatchDog can pull reset low. You should remove R2 (if you populated it)... Looks like you did. Also, as TLE8888 is powered from +12V it may pull it low when board...

Re: MicroRusEFI, not recognised by computer?

Hi.
Did you check power lines?
Check that you have 3.3V on TP3.
Check that RESET line is high (Reset button side close to MCU)
If you have oscilloscope - check that X1 is oscillating.

Re: BMW M10 carb to EFI setup

On pre 0.5.0 TLE8888's ignition outputs are available on test points. But no gpios routed to TLE8888 ignition inputs. As far as I understand datasheet ignition outputs can not be driven over spi only. But this is not 146%.

429discovery uses 144LQFP version of the chip, 407 uses 100 pin footprint. Pin count matters :)
STM32F429VIT6 is in LQFP100 package. :)
So if you want 429 chip on 407 discovery it is doable. Not sure about reasons. More memory?

I think you can solder 429 on 407 discovery. If you really want 429. Chips pinout should be same.

Re: TLE8888 Ground path.

I recall the calculated lift of the GND plane for like a 10A current was around 0.001V. That amount of lift of the GND pin is negligible from the ADC stand point. It would be interesting to measure the lift and check it against the real world. Does this include voltage drop on ground wire from ECU ...

Re: L9788 - multifunction IC for automotive engine management system

ST has released datasheet for L9779.
Very similar to TLE8888.
Has integrated 3.3V LDO. This is cool.
14 LS outputs + Relay + 4 push-pulls for stepper + 4 ignition. Less than 8888 has, but all this outputs are on-chip, while 8888 has 6 pre-drivers for external mosfets.
