Re: Wideband Controller: Fully Custom, no ASIC!

I am developing a carrier board to support dual controller modules. They will share the +5v power supply and the CAN output. Electrically, it will appear on the bus as two nodes. I added termination bits to the board as I imagine this will be one of few, if not the only, CAN device being used with ...

Can you log the cam and crank signals, and nothing else? I want to see what the real trigger shape looks like from your engine, not whether it's getting decoded or not.

Re: Wideband Controller: Fully Custom, no ASIC!

Speaking of testing: My Volvo race car has two O2 sensor bungs right next to each other, just after the turbo - I added the second some time ago especially for testing multiple wideband controllers/sensors at the same time. For this test I raised the idle to ~1800rpm, then varied the target air fuel...

Re: V12 M73 to Audi trans, with Proteus in Lamborghini Replicas

Can the software compensate for the fact that the M70 crank pully is 4 teeth off the M73 timing? You can see the sensor mount is dead center on the 4th tooth after the missing tooth on the M73. My Hope is rusEFI can compensate for the pulse difference . Andrey is this true? no problem, you can infi...

After a lot of research I finally realise that the 2JZ pattern from rusefi is completely fucked. With a friend, we take the signals from cam output and from ignition of cylinder 1 with an osciloscope. We realise that it is completely random. That why I had 1 chance on 12 to start.

If this is PnP for the M111, then presumably it is PnP for a late run M104 with the addition of a few more inj/ign drivers, no?
That is the plan, yes. The 4/6/8 cyl ECUs are the same, just with some missing some output drivers.

In that case, you can use any analog input, provided that you install a pullup resistor on that channel.

On proteus any digital input will work. On MRE, you should be able to use the analog temp inputs or the cam input. Analog v...

Do we have a sample tune and sample log of the sensor actually working? Do we actually log flex fuel? :) We log it, the channel is called "flex ethanol %" or something like that. You can watch the impact of target afr changing even as target lambda stays constant. I tested on the bench with a funct...

Re: 1986 Ford Mustang 5.0 EFI swap

On older vehicles you use the HS outputs after you run out of LS outputs so it's now worth the bother to rewire. That's the only use I've ever found for them. I guess new vehicles have stuff that is HS from the factory And sometimes there's a mix of both for no apparent reason. The factory GM ECU f...

Nope, it's not 1k, it really is a single ohm. It exists to add ESR to C1006, as they together form a snubber to damp out ringing betwee...

Oh! I figured it had to do with power consumption concerns. There's plenty of amperage from the EEC relay anyhow so couldn't I jumper your 12V to 12V_MR pin? I can't really see any benefits from adding another relay if I've got enough amperage stock? Then I could just leave pin 1 disconnected. The ...

Hmm. I saw the stuff about the main relay in the wiki but wasn't sure if it was needed.

Re: 1986 Ford Mustang 5.0 EFI swap

Also, do you really want the main 12v and 12v MR both connected together? If the ECU has a pin switched by the main relay, you want that one connected to 12V_MR, and the ignition switch connected to the other.

Very True. I intend on keeping your trace widths of 1.27mm for High Side Switches and 5V Reference, 0.762mm for Low Side Switches, and 2.032mm for 12V.
I would go wider if you can - remember those traces on the board are VERY short so they can't make very much heat/resistance.

Re: 1986 Ford Mustang 5.0 EFI swap

You mean an ERC failure complaining that the ground pin has no power supply? You can suppress that with a "power flag" (search that in the component picker) and wire to to the GND net.
