2 ECU's :S

[ST-eater]

With my conversion kit i was given 2 ECU's. I was told that one of them was chipped and the other not. Could someone advise me how to open them up to check which is chipped and which isn't.

Secondly the codes on the ECU's are different, and i dont know if i can use them both, or just one of them.

The engine im fitting is the DIZZY type with a lamba sensor in the exhaust. Believed to be an astra c20xe engine.

The ECU codes both have MOTRONIC stampped on the front, with the same connectors, but one has FP in bold white letters on the label, and the other has GX

FP- Bosch 0 261 200 185 GM 90 299 569 (FP)
GX- Bosch 0 261 200 479 GM 90 410 501 (GX)

Can they both run the engine/sensors, or is there only the one that will, or even worst case do neither of them fit?

If i was to try them both would i do any damage to the engine/sensors?

So far on google i have found (using numbers on ECU)

Astra 2 litre 16 Valve (C20XE)
88-91
Bosch Motronic 2.5











90 299 569











and

Cavalier GSi 2 litre 16 Valve
91-93
Bosch Motronic 2.5
Cat (C20XE)
0 261 200 479

Meaning that these ECU's are for two seperate engines by the looks of it. Could i use either? or is one for dizzy and one coil? :S

thats where the chip goes, mostly the 'tuner' ones have the name of the tuner stamped on them

Cheers, il have a look once i get the things open. Am i correct in thinking i can use either ECU for my engine/loom setup?

you can, i'd use the gx one tbh.

Is there any reason for this? the only thing i could think of was that the map might be slightly better due to it being mapped for a larger car... kind of logical thinking without having a clue lol
