I have a level 8 ecu with a baby pectel board how can I work out if it is a green or red to as the sticker is missing on the cover on the inside the flat upright bits on the circuit board are black & I have seen some with cream ones

IAN

 

the only difference is the chip

as it's running a pectel board, it all depends on who wrote the chip if the lambda is required or not

 

Is that the difference one has lambda & the other does not?

IAN

 

Yes. And the software dictates whether or not a lambda has to be present.
The hardware is the same for both.

 

So is the main board the same so its just the chip plus is there a way of telling what mine started life as

IAN

 

yes, the ecus are exactly the same,

the chips are the only difference
