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...

Our august release candidate is now available at the link below: https://github.com/rusefi/rusefi/releases/tag/20200803 We have had releases for a while but it seems people were not aware of them so this month is the first time we are trying to make a bit more of an announcement of it. Hopefully in ...

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.

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.

Genuine question, is the list unclear? Could it be improved?

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

I'm a little confused as they are all listed? See below. 1-- which pin does the crankshaft sensor go? Variable Reluctance #1 negative? or DIGITAL 1 Digital trigger/switch input ? You have VR sensor so: ## White 35 Pin 776231-2 | 5 | VR1 pos | vr | Variable Reluctance #1 positive | ## Black 23 Pin 77...

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.

also, anybody know how the IDLE AIR is handled on the BMW? i have nissan throttle bodies with nothing built in for idle air. Idle air on the BMW is normally done with a Bosch 3 wire (duel circuit) IAC valve. I am not sure if the V12 used the ETB for idle, Andrey may be able to confirm. You may be a...

okay i am wiring up the engine now... so a few questions 1-- which pin does the crankshaft sensor go? Variable Reluctance #1 negative? or DIGITAL 1 Digital trigger/switch input ? 2-- camshaft sensor. .. same?? 3-- coolant temp sensor? pin # ? 4-- throttle body.. 2 of them... 5-- gas pedal.. 6-- MAP...

I'm using the registered version of TS. The following picture is an example what I mean for the Ignition advance of my MS2 powered C18XEL. It would be nice to have such tuning maps for rusEFI. 3D.PNG There is a little tick box in the top right corner of the maps that should put it into 3d mode. Can...

Hi Thomas. I can probably answer most of these for you and the good news is that most of these things refer to features that have been updated or improved and the documentation has not caught up yet. So going from the top: (no knock processing, no WB-controller and Bluetooth onboard) - Andrey has co...

Welcome to the madhouse.

Another C++ developer on board would be a massive help.

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...

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.

*wave* I work within a university/research institute and we have exactly the same issues. The modern ECUs are so complex we can spend as much time working around the ECU as performing the test program. We have had some discussions about using rusEFI for some of the future test benches or cheaper stu...

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 have tested this FSIO formula out today on a discovery board and it seems to be working fine. I will rig a temporary wire up on the E30 tomorrow and see if it is happy on a car. To enable this set your TS as shown in Andrey's screen shots and use the formula below: 0 fsio_analog_input 2 > 2000 700...

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.

I think that can be done via the FSIO.

Let me ask about, we may be already able to do that.

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...

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.

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. Regarding the cam sensor issue, the toyota 1ZZ-FE uses a fairly common sensor configuration, I expect a hall eff...

The developer that was working on the 'launch control' has left the project so it would be safe to assume at this time that all of the settings presented in that menu are untested and potentially not functional. What you intend to use the launch control for makes a large difference to the amount of ...

The issue is mostly developer time, we are very short of developer time and the only way at the moment to crate more developer time is for someone to directly hire a developer to assist.

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

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?
