Bent back the clips but the top cover aint goin nowhere while the yellow painted mini torx have it screwed to the plug

Is my ECU unusual or something? Any idea what size that is, its tiny....

Still, the K&N filter went in ok

Never heard that one before, all the ones i've done, bend the tabs back lift off and fit the chip.
What yrs the car??

1990 touring

my i.s had them dunno what size they were though, thought all ecu's had them

Well, its a torx 6... and the chip aint on its own thing its soldered to the board with all the other chips --- any ideas? I could have tried to unsolder the chip but ideally I'd have access to the back of the board, and its all clipped in solid.

I'll post a pic later but right now I need to plug it in again and do some stuff....

what car is it to start with? the chip you have will be a plug in one , no need to undo any screws or soldering

Mine has tiny little torx screws as well! 1991 i.S

The I don't think the wiki guide mentions that there is usually a black plastic cover over the chip that needs to be removed before you can see the chip itself - maybe that's throwing you off?

all have screws on the back of the ecu, they hold the board inside. The only ones not straight forward are the 320's as they are duel layer

Chip to replace is top right with the white label (I think....), definitely soldered on!

Cheers!

Its not under that metal clip thing at the top is it??

No, are they injector drivers?

I revise my previous statement, I took mine apart tonight, I just didn't have the balls to pry the cover off the first time! Thought mine is different to the case pictured, it was still just 4 bolts on the top cover

Torx T6 screwdriver. These are on my ECU too, a 1990 car also. The chip was not soldered on though.

that chip is not soldered in it will come out,try some long nose pliers.

I was hoping someone would say it was under the clip.... if I get the chance will take it out again and have another look - was sure it was soldered though

Very strange,my ECU came apart just as the wiki guide,plonked Ant's chip in using a credit card to ease the legs in at one side.Well,we learn something new everyday here!

I guess with these 20-30 yr old motahs anything goes

... Will whip it out again fnarrr fnarr when I get a chance this week

I had issues with my ECU aswell, although mine looked different again to your pic, mine was a double board :/

Ended up picking up a second hand ECU here on the zone and chipped that one instead LOL

Well its definitely soldered on. Had another go and a better pic on my phone and an electrical engineer mate had a look, recognised the chip as a dual in line http://en.wikipedia.org/wiki/Dual_in-line_package

The type most peeps have is probably litterally a socket which BMW probably realised made upgrading the engine tune a bit too easy so pulled the plug on that with a drop of solder.

He suggested I could clip the 28 legs and solder the new chip on top. Or an engineering firm should have a special tool for softening lines of pins solder allowing the chip to be removed.

Pain in the ass, now my under steering cover is loose

Ho hum!



edit: fook is it really a month since I last had a go? lol

Thats an ecu i havn't seen before.
Has the car come from overseas?

Don't think so - Edenbridge pretty much all its life

Replacement ECU maybe?

Could be a replacement as the stickers on it look different to all the ones i have seen in the past.
It's a 325i right?

Yeah 325i.... was hpi checked

Funny google e30 ecu and the first link says this:

e30 ecu help
Hey
I bought a performance chip for my 1990 e30 325i Convertible. I pulled my ecu out to install the chip when i had a problem. By the way my ecu is a 525 in pretty sure. My factory chip was soldered in.

Just checked and my chip number is 1267356425 which is a 380

aaaah should look like this

5% of 318s ECUs here are soldered, maybe the instructions should be updated to reflect this

An update, never one to run from a challenge haha, I've bought a solder sucker and am looking to cut the chip pins and solder on a dip socket....
