Standard 3B chips part numbers

[SteveH]

Hi,

I'm returning my 3B ECU to standard to sell with some spare chips. The problem is I have so many chips I can't remember which were the standard part numbers

Does anyone have the part number for the 3B boost and Engine chips please?

I have these two with Engine and boost written on them, but I want to check they are both from the 3B. Failing that I'll burn some copies from files I have stored on the PC.

267 357 358 - Engine
267 357 519 - Boost
267 357 529 - unknown but must be a boost chip!

Thx

Well I documented the following valid for 3B S2:

1 267 356 560 (B57701) Top
1 267 356 531 (B57618) Bottom

If you can read them it might give you a clue via the size!
They might be off another 20V variant Ur 20V/200q 20V perhaps.

If you look at the pics on this thread there is a pic of some original 3B chips. Seems to confirm what I posted!

Cheers Robin. Very strange, at least one of these chips came out of my 3B ECU! I copied them when I took them out so I'll burn some new ones.
