https://www.vauxhallownersnetwork.co.uk ... gs.147203/...Yeah, the looms are interchangeable. You can run an NE engine on an SEH ECU and vice versa (so long as they're both Bosch Motronic 1.5's), although it's not a good idea to mix and match the engines and ECUs for long because the engine will either end up running rich or lean, depending on which engine has which ECU plugged into it.
If one ECU is bigger and looks different to the other, you probably have the old engine management system, Bosch Motronic ML4.1, as used on the <1990 2.0 8v's (in which case, the ECUs won't be interchangeable). Motronic 1.5 was used from 1990 onwards
1.5
This system was used on some of General Motors engines (C20NE, 20NE, C20SE, 20SE, 20SEH, 20SER, C20NEF, C20NEJ, C24NE, C26NE, C30LE, C30NE, C30SE, C30SEJ, C30XEI...). The system is very reliable and problems encountered are usually caused by poor contact at the associated plug/socket combinations that link the various system sensors to the Electronic Control Unit (ECU). Predecessor of the ME Motronic. Also used in the Opel engines C16SEI
https://en.wikipedia.org/wiki/Motronic4.1
The Motronic ML4.1 system was used on Opel / Vauxhall eight-valve engines from 1987 to 1990,[12] Alfa Romeo and some PSA Peugeot Citroën XU9J-series engines.[4]
Fuel enrichment during cold-start is achieved by altering the timing of the main injectors based on engine temperature, no "cold start" injector is required. The idle speed is also fully controlled by the Motronic unit, including fast-idle during warm-up (therefore no thermo-time switch is required).
The ML4.1 system did not include provision for a knock sensor for timing adjustment. The ignition timing and fuel map could be altered to take account of fuels with different octane ratings by connecting a calibrated resistor (taking the form of an "octane coding plug" in the vehicle's wiring loom) to one of the ECU pins, the resistance depending on the octane adjustment required.[12] With no resistor attached the system would default to 98 octane.
There is a single output for the injectors, resulting in all injectors firing simultaneously. The injectors are opened once for every revolution of the engine, injecting half the required fuel each time.[12]

Creo que peco de novato, me baso en lo que me comentó mi mecánico de confianza tras cambiar el motor. Hablando con el anterior dueño del motor parece que el sensor de aceite sí que está presente:
Gracias por la respuesta. No lo he comprobado por lo comentado anteriormente. Aún tengo culata + bloque + todo lo del motor anterior, pero el sensor del aceite de un C20NE está en la tapa del cárter? Perdón por la pregunta de novato. Serían muy buenas noticias lo que comentas. Si fuese así, le pongo la tapa cárter del que tenía antes y a correr? La respuesta de Alan parece corroborar que sí, que el sensor de aceite está en la tapa del cárterLa_Machine escribió: ↑Mié, 13 Mar 2024, 08:37 Edito: por gañan y no terminar de leer. Veo que el modelo donante suscita dudas.
Hablamos del "parche" en el carter, ¿Cierto?
De ser así, ¿no es compatible la anterior tapa del Carter con el nuevo motor?
Gracias Carlos. No tengo ni puta idea, aunque sí que creo que puedes tener razón y que lo que pillé no es un C20NE, sino un 20NE. esta foto es de unos pocos días antes de pillar el motor:
Muchísimas gracias por esta información. Me pongo en plan guiri -> I honestly had no idea about this, and that's why I now think my "new" engine is a 20NE with Motronic ML 4.1, in contrast with my "old" engine C20NE with Motronic 1.5, which could explain a lot of wtf is going onHerr Farruku escribió: ↑Dom, 05 May 2024, 23:11Muxo ojo, muxo_frio, que las diferencias van más allá de la forma de la tapa de la distromuxo_frio escribió:...Pues resulta que este C20NE es pre-1994, pues la distribucion lleva tapa cuadrada (igual que el que tenía antes mi calibra) pero sin embargo hay una diferencia notable: No tiene donde enchufar el sensor de nivel aceite.

El C20NE puede venir con dos ECUs diferentes, en principio según año/modelo. Motronic ML 4.1 hasta ~1990 y Motronic 1.5 a partir de entonces. ¿Tienes la ECU o al menos el mazo de cables del donante? (el conector de ambas ECUs es distinto). Aquí hablan de operar un NE con ECU SEH pero la idea es la misma, observa el comentario:
