m30 gurus needed.!

Hmm I need to crack the ECU open and have a look what chip it has inside I think...

I'm guessing some crap ebay "tuning" chip would cause rough running.? If that what's been put in..

Get Speedtouch's "Mild" chip as a replacement if it has a cheap fleebay one.

As above should be a 179 but yes a later m20 ecu with the right chip will work IE a 173.
Try the correct ecu as this sounds a bit like the problem. Have you had all the plugs off the manifold and managed to swap the tps and icv plugs when refitting?

Zorst, I didn't do the engine conversion. I got it off a guy I know as a running project for cheap, he knew it didn't run great but had to sell it on to finance other things. He completely rebuilt the engine and fitted it but never got round to ironing out the fine details....

OK, just pulled the ECU. Upon first look, its obvious its never been opened before, metal tabs were factory sealed and no tool marks where you'd normally see after prying the metal tabs up.

Does anyone recognize the number on the chip? Is it from a m20b25?

[Speedtouch]

A '173' ECU is a 325i one, so yes, chances are, it's probably a 325i chip.

I can supply either a standard or upgrade M30B35 chip that will work in that ECU.

[mcbonio]

I just googled "1 267 356 288" its deffo for the m20b25.....

Can you do me a mega cheap chip Speedtouch buddy old pal? I'm broke until payday...

Thanks,
