* verify and fix harness

* and preferrably use the __old__ ECU because it was reliably communicating during all tests, with inputs outputs behaving.

If and only if your harness is really documented here __and__ verified

* and still experience problems (which must be documented very exactly including ECxx pin numbers and values, without the word "some")

* than pay +80 EUR and connect new ECU,

* upload your config after inputs are good, and outputs also tested.

* Please make the verifications and test in next few weeks, and latest on 2022-02-22 please send back new ECU (that hasn't been plugged in)

** (to Budapest address specified by crew)

** or send back old if the new has been plugged in, +80EUR must be paid in that case

* (or keep both, and pay +400 EUR in that case)...

Please carefully check that all 5 GND-s are connected, and EC36/23 flyback also. See the paper of the new ECU (apply to the harness).

Plugging in new ECU without carefuly checking harness and documenting __and__ thorough verification is not recommended, and voids warranty. (As the old ECU also worked fine on test-bench but misbehaved in the harness, the new ECU will most likely misbehave or get damaged if plugged in without thorough harness verification or rework, so it is very important to do thorough checks).

Even if it works with one ECU but not the other ECU, it is very likely the harness has some problem (and might surface in the future). We hope the thorough tests reveal something, and old will work well... But include the new so you have the option to try (without more delays), but - however tempting it might be - plugging in new is not the way to solve this.
