The row of solder is where most chips/daughterboards will go

does anyone have an actual pin-out diagram for this ECU?

do u have a e-mail and i can send u some pics of the ecu and u can tell me if u think its been chipped ...also when u say the row of solder where do u mean :wonder: ... today is the first time ive looked at a ecu so bit of a newbie in this department ....

Youve probably been mislead. It cant be invisibly altered: if it has been adapted then therell be a rectangular EEPROM in the location vacant in the picture in post 2. JDM cars need a socket soldering in: UK cars have a socket already.

can some1 tell me how to post up pics ive just signed up to photobucket as im sure thats whats required ive put the photos on there just how do i get them from there to here ...

copy the "direct link" with the right click, then click on the postcard icon in the toolbar above the message box here

http://i318.photobucket.com/albums/m.../scoobynet.jpg

a new box will appear, clear the http:\ text and paste in the new link and click ok

...or click 'quote' on a post with picture; and observe the syntax...

not sure if these pics are gonna come up but here we go ...:wonder:

Completely standard. 260PS, just as JECS intended.

ok im goin to photo bucket copying the link with a right click ... then goin to sn clickin on the pic icon pasting the new link in and all im gettin is a box with a cross through it no pic ..... just like my last post ...

cheers :thumb:

Open the picture > right click and copy the adddress/location and then paste that into the reply box here. Prefix it as follows: [img] and suffix [/img]. If you click quote on my post above - youll see what I mean.

Just post the link on here mate, once we know what it is we can img code it.. and see if it's a photobucket thing or you :D :D

*shakes head*

Its HIM; otherwise how do you explain my post with his pictures in it?

Oops, didn't realize that was Lee's pic you pit up GC8 :wonder:

OK... Lee you're doing it wrong...:brickwall :D

I had quoted his reply, but in the end I had to C&P the picture address to make it work.

Sorry to hijack this thread but am I correct in thinking that any 4 plug ECU can be used in an early 4 plug car IF it has a Polar Performance chip fitted?

I ask because I have a Z4 ECU in my car and want to fit a Polar chip and it is cheaper to buy a 7K ECU from ebay as the chip socket is already fitted (mine would require soldering)

Youre absolutely right. Better to keep your more desirable Z4 and find an old UK ECU: itll be cheap and it will have the required socket fitted.

So is it the same for say an ecutek remap? i.e a chip soldered on?

That depends on what you are after, on their site ECUTEK offer a replacement board that fits into the original ECU casing

ECUTek is a software solution.

ok ok ... it was meee .. lol

sorry have not replyed in a day or so. But i have figured out what i was doing wrong when posting the pics. When i was posting the link from photo bucket i was just copying the address from the tool bar at top of screen on photobucket ... what i didnt realise was that they also give u a list of other links 1 of which is the dirct link which is diffrent to the one toolbar ..

sorry u was right the first time ... just didnt see the direct link option !!:thumb:

so now ive figured how to post... how do i resize ?? i ajusted the size in photobucket but still takes on full size when i copy the link to sn :thumb:

Thanks for all ur help gc8 .. the 1 question i have left is where would the chips be solderd on, i think on the pic that i tryd to post but failed .. and then u put up u can see more clearly .. u can see three lines of solder .. would it be on any of these ..??

In your picture above - in the 10 o'clock position. UK ECUs have a rectangular socket there, whereas JDM cars just have the foundations for it (as it were) on the board. A socket can be soldered onto these boards, but its easier to buy a cheap UK ECU with it already done and preserve the more valuable Z4. When the ScoobyECU / ESL part is fitted it will over-ride all of the ECUs existing parameters, so the part you start out with isnt important.
