fault code questions: 1111 ecu ... happens on some modified ecus?

[Josh-stateside]

HI every one

I am registering two fault codes:

1111 (Blink Fault Code), VAG1551/2 Fault Code Number 65535 Engine Control Unit (ECU) Defective memory circuits, incorrect Checksum for EPROM(s) (this can occur on some modified ECU's) Check ECU ground connections, Replace ECU?
2111 (Blink Fault Code), VAG1551/2 Fault Code Number 00513 RPM sensor Open or short circuit, Defective sensor & cables, metal fragments on flywheel teeth

Is this true about modified ecu's? That they can pop code 1111. I don't know if my ecu is chipped or not?

Any help is appreciative in the path that I should check to correct the problems.. I am searching hard.. but I will take what I can get.

Thanks
Josh

hAHA....

WHat a dumb idiot I am ...

Engine wasn't running when I checked them, because I am not sure about an oil pressure issue.

so with the motor running.. I shouldn't get 2111!!!

So 1111 is the code.

The engine seems to be running well.. I am not sure why 1111 would pop.

Anyone?????

thanks
Josh

Hey wait a sec..

How do you tell the difference between 0000 and 1111 with blink codes?

Thanks

Well done!! you seem to have fixed that all by yourself!

An interesting insight into the thought processes of the mind..

(I'm only jealous, I'd never work anything out for myself, at least not with an S2 anyway!)

Well done Josh..

With the swap I am doing I sadly have the majority of wiring memorized, including the bently diagrams. i know most of the positions of the wires on the ecu too.

I can be obsessive with knowledge as my girlfriend found out last night.
