Perfect, thank you very much.
What do I have to do next?

I have done exactly what you have showed me in the picture.
This battery is at 12.5V.

Watch the TPS meassurement. There is no TPS connected of course, just the 3 wires. I m using the internal USB to connect.

My laptop is connected to the main connector. I have tried with and without charger. I have not changed the original battery to chassis setup and it worked perfectly. I have meassured the continuity of the ECU grown to the chassis and it shows a great connection. image.png This is my connection to t...

malfunctioning voltage regulator? does it happen during cranking? bad battery?

The engine is stopped and I'm not cranking the engine. I'm checking the sernsors and actuators of my EFI system and found this issue when I connected the ECU.

I have all the connected cables in the crimped pins inserted in the connector. The ECU is supplied with 12V from the battery with pins 1 and 5. I made this diagramm to create the wiring harness image.png If I check the voltage as I showed in the picture in a previous post, in the last log the voltag...

The last upload failed. I have reuploaded it. In this log, the voltage is all over the place. I'm not touching anything and the TPS and MAP are uncontrolable but should be steady.

I have posted a new log. This time the voltage is higher ever though the battery voltage is still the same

I have uploaded the tune and log. I calibrated the tps 2 min ago and I didn't touch it in the log.
It doesn't show in the log, but sometimes the tps value shoots up to past 100% and the Vbat increases at the same time a bit (1V)

When this picture was taken, Tunerstudio said the ECU was getting 7.6V
I bought the ECU directly form the online store preassembled.
Where do you suggest I search for the problem?

I m supply the ECU with 12V with a relay conected to the ignition key to pin 5 and with the main relay to pin 1. With a voltmeter I measure 13V on both pins on the back side of the ECU.

Hey all, I m a college student that is restomoding his Peugeot 205 GTX, changing the original carburetor to EFI. I m running into a bit of a problem and I was hoping someone could help me solve it. When I power on the ECU (microrusefi) and I connect my laptop to it, Tunerstudio shows that the voltag...
