ABY ECU Intermittent issue

[twoqu]

A low tech way of assessing whether the ecu has been chipped is to inspect the tabs that secure the cover on the rear. There is usually evidence of pry marks as the tabs need to be bent up to remove it!
However if you really want to know you will have to open it. Not that difficult but there is a knack to it!

It is chipped I know that for certain, have already opened it once The problem is knowing it's good....

This is for the OP, not you Robin:

I guess you don't need my ECU opening hints then.

I can't read the label on the chips and I don't recognize them as anything that I know. Any better (closer) photos?

Well unknown chips and a checksum error would tend to suggest an issue. As you have suggested a subsitution would prove that!
Sometimes if you are lucky a diagnostic check with VCDS would bring up a Vendor. Withot knowing their origin, its difficult to comment.
Is the engine stock otherwise?

Engine is stock yes, I'll open the ecu and get some more photos that may help....

And I just thought, the waste gate spring I think has been uprated.

Quickly PM me your addresss. I have some some stock chips you can try.
Any funny business and you will be visited by my associates in Clacton!

PM'd.... Thanks

Missus wants me to go to the cinema with her tonight, if I can play any guilt cards I'll get in the garage tonight otherwise it'll probably be Sunday!

[twoqu]

Tim.
Check Pm please!

Enjoy the cimema unless its a chickflick tonight.
Not much you can do until the chips arrive. Might be worth devising a temporay OBD port so that its possible to hook up VCDS for fault finding. It only needs power/earth and the ecu line.
Lets see what happens
The chips are 1 267 358 021/022 which i have X referenced to ecu 145/146 which is the A (unimmo)version I hope.

ABY ECU Chip Photos

I snuk out while she was getting ready...

Here are the higher quality piccies...

Never seen those chips before. The lables look like something irrelevant that was cut up and used just because it had a sticky side. The "285" and "285PK" imply 285 hp. However, that is not possible with a stock ABY 2.5 Bar (250 kPa) MAP sensor

[edge_devil]

That's kinda what I thought. Stock ecu on the way so ill give them a go and triple check the wiring.

Sitting in the cinema now. .but I have a photo from the soldering of the rear of the board...not good!! I'll be re doing that and checking the other one. I'll post the photo later.....

Here you go: http://www.s2forum.com/forum/member.php?u=105 Pretty sure he knows what's inside your ECU.

I know he does supply chips and the text on your ECU is Dutch. 1 and 1 makes 2.

[edge_devil]

Zou wel kunnen kloppen want de motor en ecu is Nederlands

I'll send him a message he may be able to help. On a side note, where can I get the upgraded MAP sensors?
