ecu chip

[scjimbo]

I'm thinking of getting an ECU upgrade chip from speedtouch.

How do i find out my ecu code?

Cheers mate. I looked on that before but mine is a 1987 320. Which as far as i can see comes with one of two systems.

I'm probably just being a plank

or check your ECU as someone may have swapped it over or it may not be compatible with the one you have.

Thats what i thought would be best. Is it actually written on it somewhere?

If your car is an '87, you're going to have to physically look at the ECU. There's no other way to confirm it.

Have a look at this ECU:

You can clearly see the code number on the big sticker, it's the last three numbers you need.

As an aside, I have one of Speedtouch's "Mild" chips for a 320 if you're interested

Oh really? PM sent

The ECU is under the kick panel on the drivers side, check it and open it up to see if a chip hasn't been fitted already.

Cheers dude. Just off to have a look. The bloke i bought my 30 off was 72 so i doubt it somehow.

You don't have to open the ECU; just look at the metal tabs underneath from the cover that fold over the base (you'll understand when you see it). If those tabs look chewed or scratched, then the cover's been off at some point, usually for chipping. If they're clean, no chip.

Well just had a peek. all looks pristine and untouched under there. turns out its a 309 ECU.

[Speedtouch]

Alas, a 309 on a 1987 320i will be analogue L-Jetronic, and can't be chipped unlike the later Motronic.

Your only option, should you wish to chip it, is to convert to Motronic 1.3.

[scjimbo]

Cool ok mate. My car would be a pain in the ass. I'll put a wanted post up. Is it a pain in the rectum to convert to the other ECU?

[Speedtouch]

It is quite a mission. See mattyb's thread:

And the Wiki guide:

Cheers mate seems quite involved. I might get a quote for my mate whos an automotive sparky
