It works. The engine is running on SENT TPS.
One suggestion, remove the other pin options from the dropdown for SENT input. Why would you give the user an option if there's only one pin that can possibly work?

Do I need to use AN temp 2? In latest snapshot firmware it lets me select any of the AN temp inputs.1&2 were already used for IAT and CLT so I picked AN3, and removed it's corresponding capacitor C53. What does "no ICU" mean?

I removed C53 from my MREv5.4 and connected ETB SENT signal wire to AN temp 3, selected AN temp 3 as SENT input and GM type 1. I get error "No ICU on selected SENT pin".

?? The data sheet for TLE9201SG says it can work up to 20khz.

Another thing I wanted to mention, GM is using 10kHz to run the ETB, and it is virtually silent. When I use the ESP32 at 10Khz it makes an audible noise, but less than MRE at 3khz. The noise is not an issue for me, I am just curious why we are limited to 3khz, the TLE9201SG is good up to 20khz.

Awesome. I should have time to test it on the Chevy Spark engine in the next day or two.

No rush. I made an adapter to fit the Bosch ETB with analog TPS. Engine is running and tuned well enough for some testing. Throttle control is much better (more linear and predictable) than with the stock ECM with it's torque based control strategy, but I'm still not sure if it's going to work. Seem...

I have a generic ELM327 device connected to android/torque via USB. The ELM is plugged into OBD2 port. This was all set up and working with the factory GM ECM CAN bus, though I never used the AFR gauge with the factory ECM. RusEFI gets AFR from a 14Point7 WBO sensor connected to pin 26 of MRE, stand...

I have an android head unit running Torque Pro app for gauges. The AFR gauge in Torque doesn't match what I'm seeing in Tunerstudio, it seems to be inverted. If TS says 10 Torque says 20. Is there something I can do to correct this in TS? I'm using a 14point7 wideband which seems to be working prope...

I postponed the Acty EFI conversion, too many other things going on. I have all parts on hand and all fabrication is done, just need to find time to install and tune it. I took a distributor from some other honda engine and modified it to fit the E07A. I gutted it of everything except the 1x and 24x...

This is the pinout I have been using https://github.com/rusefi/rusefi/wiki/Hardware-microRusEFI-wiring The problem is that it doesn't name the output types. It describes the different types of outputs, and says which pins are outputs, but it doesn't say which pin is what type (gp_low vs gp_high), th...

No worries. The scattered info can be frustrating, but I knew what I was getting into when I purchased the hardware.

Yes, that fixed it. I tried that before and I didn't think it made any difference, but now I realize my timing light is not working and that was part of the problem.

Thank you, I believe you are correct, the primary is inverted. And yes I have the plugs out.

Thanks for the link to setup info. Yet another very helpful page that I have not seen before.

I am trying to set up a microRusEFI for a GM LV7 Ecotec. It's a 4 cylinder with individual coils, has a 60-2 sensor on the crank and what looks like Bosch Quick Start on both cams, I have the intake cam sensor connected. I'm getting no spark. I'm not familiar enough with rusefi or Tunerstudio to kno...

I've discovered an issue with my setup. ETB only works with USB connected. As soon as I disconnect the USB cable from my laptop the throttle powers off. Reconnect and it powers on. It doesn't matter if Tunerstudio is running or not. Any idea what's wrong?

Thanks for that pinout diagram, in all my searching I never saw that, I've been going by the one on github which doesn't say anything about which pins are high low or push-pull.

Yes, it is working now. So JP2 setting affects all GP outputs 1 thru 6? Ignition outputs are always 5v regardless, correct?

I need a 12v output to control my fuel pump relay. I have microRusEFI v0.5.4. I found JP2 for switching high side level from 5v to 12v. What else needs to be done?

Sounds good, let me know when you have something. I still need to set up my triggers and other stuff.

OK, I wired up a Bosch 0280750149 ETB. I'm impressed with the ETB control, no doubt it will work fine for me. So now it's a matter of fabricating an adapter to fit it to the engine, or getting the SENT TPS to work and use the original ETB. AndreyB, How soon could you have firmware available for test...

I've got no problem being the test mule for SENT, but I would like to have this project wrapped up as soon as possible. I can dedicate nearly unlimited time to testing, and I have a very good understanding of hardware and electronics, but I'm a novice when it comes to coding. I did write my own code...

Update, it is SENT. That is not a term I was familiar with before now, but the pinout for the factory ECU (Bosch E84) says SENT1 for the TPS pin. I assumed it was a potentiometer based on the symbol on the diagram, as well as the diagnostic info in the manual describing variable voltage. What would ...

Is it possible to allow using ETB with only one TPS signal? The 2016-2023 Chevy Spark has ETB but only one TPS. Maybe I can connect the same signal to primary and secondary TPS channels?

I'm looking at available options for trigger hardware, leaning towards an optical sensor due to the small space available. Can we decode this AEM cam wheel for Nissan? It looks like the Honda 1+24 pattern should work. https://www.aemelectronics.com/sites/default/files/product_image_product_sections/...

Both of the following pages say: Will be supported soon: Stepper IAC support

https://github.com/rusefi/hw_microRusEfi
https://github.com/rusefi/hw_microRusEfi/blob/master/readme.md

I read another post from a few months ago about IAC stepper not working, and no resolution. The readme on github says it will be supported soon. I could not find any mention of it working. I haven't received my hardware yet, but if it can't drive an IAC I have no interest in using it. I don't have a...

I just realized stepper IAC is not working with MRE? And there's no way to set up dual custom trigger wheels?

That's an old ECU, it hasn't been available for at least a few years, no sense comparing it to anything current. I used one to run a M70 V12. At the time there was nothing else that could come close to the capability of that ECU unless you spent twice as much.

I was thinking it may work with those settings, just wasn't sure about using 0 for skipped tooth. Thanks for the confirmation. I'm leaning towards scrapping the distributor and going COP. Parts for these are kinda hard to get in the US, so anything I can replace with common domestic parts is a plus....
