August 2020 Firmware Release

This month is going to be the start of us making a bit more noise about our software releases. We have been doing some release builds for some time (regularly since 2019) but it seems not everyone is aware of them. So with that said rusEFI presents it's August 2020 firmware release. https://github.c...

Re: E85 / Flex fuel logic

Just a general FYI, I am working on the framework for implementation and what code I am able to write so that it will only need integration from someone that knows the firmware better.

97 f150 is likely eec-iv, which we have a breakout board for the mustang version.
Would have to check the pin out and keying though.

Re: Breakout Board microRusEFI

I would recommend three improvements: silkscreen, silkscreen and silkscreen. On both sides. I am stunned. Normally it would be LEDs :P Though in this case some LEDs for some of the outputs could be done with some jumpers if you wanted to be able to connect a visual indication of a channel working.

Well I am glad I made a mistake and ordered the SMD ones with my last BOM, that resulted in me getting a bunch of these on next day. :lol:

The other problem we have seen with Bosch ICs is reliable supply. It is either dodgy Chinese supply or chips removed from OEM hardware.

Re: Connection problem with eBay board

I think getting a stm32f407 discovery is probably going to be your best option.

While rusEFI might work with other STM chips there are so many variation that we just cannot be sure any chips other than the officially supported ones will work.

One thing you may be able to do is get a donor ECU and remove the plugs. A 1l vauxhall ECU is worth nothing in the UK, you can pick them up for £20 on ebay. Forget using an ECU as a donor, this is a ME7.x based ECU so it's a funny non-standard internal setup without a PCB. I believe one of our memb...

Re: [info] rusEfi Scheduler Performance & Accuracy

That's not actually surprising.

When I raised the question of timing accuracy at work the consensus was 0.5 degree at 6000 was plenty good enough and that anything tighter may just be a statistical improvement and little gain in practice.

Experience has show the best cost vs performance one you can just open the box and plug right in is the AEM X-type. About $150.

SLC also do some cheap stuff but I am not sure the extra time is worth the lower cost.

I am told it is possible to set a new rev limit based on an input being powered.

It might be best to start a quick thread asking how to set the rev limit using the FSIO.

You can use the wideband to tune and then remove if you want to, watch out though as you may change the engine tune by changing the exhaust tuning. You are unlikely to hurt an LSU4.9 sensor with it installed very close to the cylinder. I have had the pipe around the sensor glowing redhot before with...

Re: vw 1.8t 20vt papillon electronique

I assume you mean a variable RPM limit based on speed.
So a 6x2 table giving RPM in one cell and a RPM limit in the second cell.

Very similar to the way it is done for the old motronics.

Re: BMW M10 carb to EFI setup

The M10 coolant sensor is the same as the M20 one.

Most common BMW (and Bosch in general) sensor curves are in the attachment.
The curves were carefully measured using an insulated 3d printer heat bed to get precise temperatures.

You will not get reliable Lambda sensor AFR readings from zoomie headers, there is often too much reversion along the tube that pulls 02 into the tube and causes an incorrect AFR reading.

The similar VW/Bosch 4 cylinder module is cheap and has readily available amp connectors.
I think I paid about £35 for 2 modules and £15 for two sets of connectors for them (to run an M20 with M50 COPs).

PN is 4D0905351 and plugs can be found on ebay

Re: Unable to do MicroRusEFI first flash on new pre-assembled board

Weird.
I have had issues with solder bridges under some of the smaller chips stopping the USB working but that was a hand assemble and does not explain why it worked before.

is it possible something between the usb and stm has failed? Either a trace or a component?
