Ecu 2.0 8v

[jonnyk]

I've done a little research but thought I'd ask, as far as I can read my 8v gte has two rows of on its ECU , and quite a few of the SEH ECUs have 3 rows as the are from the later mk3 cavalier, but does anyone know which numbers are for the 2 row SEH ECUs
If all I've written is way of the mark could some one put me right please thankyou

Re: Ecu 2.0 8v

2 row motronic ML4.1, ident FH, bosch 0 261 200 116 20SER engine
3 row motronic M1.5, ident GD, bosch 0 261 200 374 20SER engine
3 row motronic M1.5, ident GC, bosch 0 261 200 372 C20NE engine (only fitted to cabriolet in the UK)

3 row fitted 1990 onwards iirc

Re: Ecu 2.0 8v

My ecu number ends 115 with FH ident so I'm going to guess that I can't put a SEH ecu on my car, does that tally?

Re: Ecu 2.0 8v

as you rightly pointed out there are slight variations of last 3 digits of the bosch part number (usually for different vehicles) but its not the case that SEH ecus are 3 row, you can get both 2 and 3, just like astra 20SER ecus.

if you can find a 2 row SEH ecu it will work fine, but it wont be the same ident as astra version. for example the 3 row SEH ecu for cavalier is GF, 3 row C20NE ecu is GE

Re: Ecu 2.0 8v

bit of googling, 2 row cavalier ecu is FU ident, bosch part number ending 133 and 134

Re: Ecu 2.0 8v

You can always just swap the loom for a 3 row type only takes a few minutes, the only other thing you need to change is the throttle pot rest of it can stay the same and it plugs in with no hassle.

Re: Ecu 2.0 8v

Oooo didn't think of that, that's an idea, will any astra 3 row loom work?

Re: Ecu 2.0 8v

If it's off a 2.0 8v and has the flap type air mass meter I don't see why it wont, I would suspect a cav loom would also fit ok.

Re: Ecu 2.0 8v

That's exactly the same as what's on car , checked it earlier when I got 5mins , so that's a SER ecu correct?
