AA+john-deere-utility-mat+(1) L12 - Phoenix ECU, DE10 - Stanadyne control, TIER 2 used in John Deere, Claas & more

As you can see from title... I want speak about L12 - Phoenix ECU, DE10 - Stanadyne injection pump control, TIER 2 engines... used in John Deere, Claas, Timberjack & more...

Here you have a picture with L12 Phoenix ECU... Exist more than 40 reference code, REXXXXXX... Here you have one of them.

I need John Deere, Claas, and another specialists opinions, specialists that know very well this ECU, this injection pump and John Deere engines & co

In the paste ( about... 8 years ago ) I made a simulator for this ECU used in Claas & Renault tractors. Here you have picture...

This simulator help me to repare / program / probe over 300 L12 ECU but... this simulator is made for L12 Phoenix ECU used in Claas / Renault tractors with John Deere engines. Along this 8 years of work with this simulator I see that if I want to test a L12 ECU used in John Deere tractors or John Deere / Timberjack forestry harvester or forwarder or in another device... the simulator don't work well, don't see various sensors or don't see well the sensors or another rare manifestation. In this time I don't have time and access to JD Service Advisor, I don't have JD interface... etc. But...

In present it come to me more and more L12 ECU from John Deere tractors, from Timberjack / John Deere forestry machine and my simulator don't work well. I install John Deere Service Advisor, I buy an original EDL interface and I start to make a new simulator that I want to cover all models from L12 Phoenix ECU that is used to control the DE10 Stanadyne injection pump.

In my research I discover 4 variantes to mount this ecu ( 4 electrical schematics that is not iguals ) here you have this 4 schematic diagrams...

1 - this variant is used in various Claas / Renault tractors 12Volts

2 - this variant is used in John Deere tractors 12Volts

[Image: L12-3-JohnDeere-12V_zps1tlxcylp.png]

3 - this variant is used in Timberjack / John Deere forestry harvester and forwarders 24Volts

[Image: L12-Timberjack-24V_zpsjlm8nspc.png]

4 - this variant is used in a compressor that use John Deere Tier 2 engine 24Volts

[Image: L12-1-Compresor-24V_zpson4ukzoa.png]

The hardware mode that is used L12 Phoenix ECU in this 4 variants is slightly different... there is small difference in the sensors region, in the mode that is made acceleration ( I know... acceleration on CAN bus... analog or digital potentiometer etc.) but if you see in the in the 3 and 2 image... one have accelerator pot and another a oil pressure sensor in same pins. And the difference continue....

My first question... do you know more different hardware variants ( more different schematic diagram ) in that this L12 Phoenix ECU is used ?!
Second question... dou you have and want to share PLD files for this L12 Phoenix ECU ?!
Another question... Somebody can download an share original PLD files for this L12 Phoenix ECU ?!
Another question... do you know original reference for this ECU ? RE ?XXXXXX ?! If you know, please post them here.

Thank you for watching and... why not... contribute at this post.

Best regards, Dan
