nope no cat or lamda

but the car is a 1989 car so over ere it should have had a cat fitted but it has been taken off i assume

[rubjonny]

ah so you are not in england then?

[sidecarphil]

no mate netherland's LOL sorry but i am english Expat

[rubjonny]

aha!  I wouldnt have thought a lambda retrofit ecu would be significantly different to a 'normal' one, but it seems it is the case, unless there is something else wrong

according to etka the ecu with part number 037 906 022BB can be replaced by:
037 906 022CT
037 997 022FX

there are probably more that will work made before the BB code ecu but I can only look forwards, not back!

[sidecarphil]

thank you very much

i found a 037 906 022 CT on fleabay

dont suppose you have one ??

the digifant 2 ecu with lambda is very simalar to the non lambda one,   TC's  digi2 ecu runs lambda

[rubjonny]

yeah thats what I thought, etka has different numbers but assumed it was just a bit milder map for lambda or something.  obv the ecu plugs are the same!  plus when vw retrofitting a lambda dont want to be rippin out half car loom...

[danny_p]

just thought in theory i have diagrams somewhere.

appently there are 4 maps stored on digi 2 ecu's  so all the ecu's have the same maps but depending which ecu it is depends on whitch map it reads

[danny_p]

lambda ecu   

pin 25 - ignition output signal to control unit
pin 18 - ignition signal input from dizzy
pin 2   - lambda

[sidecarphil]

so can i just swap the pin's around on the wires ??
