Re: Wideband Controller: Fully Custom, no ASIC!

Is it possible to get the can address and position of the Lambda data. Reading through this thread AEM X series protocol was used. but the AEM output on a different CAN ID address 394 if im correct. Im seeing ID of 400 and 401 on this unit. also the aem is buffer 0-1 Im not seeing valid data on that...

Re: VSS digital input

My next question is, Why do the range of usable pins change with updates. Im using the discovery firmware, I was using PD15 as a injector the Comms LED I have set to PD12, But the latest firmware has taken away the Status LED selections and is also forcing Comms LED to PD15, even changing the INI fi...

Re: VSS digital input

So after a change in the resistors, it is working. Was hoping I could have used Rusefi as a alternative on my ecu's for what is already out there, but future ecu's will work perfect. Today's goal was to get my CANBUS displays working on Rusefi. Ill also add the CANBUS wideband to the car also. https...

Re: VSS digital input

current limitation, on 4 digital input circuits im not using a op amp, these have a 3.3v zener diode to protect them also for over voltage, putting 12v onto one of these pins the zener will protect it and as the current is weak on the other side of the divider the zener is able to sync the voltage w...

Re: VSS digital input

The selection of the voltage divider is its output is 3.3v at 5.2v and ive carried over from when I was working with teensy 3.5, 0.1v over will kill a teensy as they are not 5v tolerant at all on any pins and I haven't really until now had a problem with those values.

Re: VSS digital input

so the same pin on other firmware works fine on the hardware, functions perfect as a square wave 5v running through a voltage divider to 3.3v and is a floating pin. I get 3.3 volts at the processor with the pull up enabled. But rusefi it doesn't work unless I bypass the voltage divider, but bypassin...

Re: VSS digital input

Ok seems to default to a pull down. I have got it working by removing my voltage divider as the resistance of that can't overcome the trigger threshold. with the 5v side the mcu pin only gets to 0.7v with the voltage divider inplace, Takes my 5v to 3.3v normally, But the pulldown is too much for the...

Re: proteus iat and clt sensor drops temp when power apply

Im running my own hardware, but mine does the same. I've just calibrated to the correct value when the car is running. I would say its a firmware thing and maybe to do with the voltage conversion for the battery sense on the 12v

My next question (and ive read the thread 10+ times and BOM) I can't find the part number for the 12 pin carrier board connector anywhere.
Can someone please tell me the part number.

any chance of a .bin file for this firmware, Im not a coder and can't get it to compile even watching 100 videos on how to do it, all I get is it can't find the directories after it does the bootloader section.

Re: Trigger settings - VVT sync requirement

Im working on getting logs, I don't get much of a chance to run this engine on the rusEFI as I use it as a daily, it currently runs on the "Other open firmware".
I do appreciate you guys helping too.

Re: Trigger settings - VVT sync requirement

So ive run the car with the modification.
Better 80% of the time.
Can i run the injection in a Semi-sequential without changing the sequential wiring? I don't want to run simultaneous, so it will fire pairs of injection?

Not having even started on the car,any idea whats not going to work once the factory ECU is removed or should i be piggy backing on to the standard system?
