Author Topic: DINAN chip - now a mystery - argh! (Read 4237 times)

So, a couple years back, someone gave me a DINAN chip for an M42. It had a sticker with a part number on it and now that sticker is gone [hardened adhesive, blown away?].

I never installed it because I could not confirm if it was the exact chip for my ECU or not.

It's burned onto an ST Micro 89017
M27256-2FI eprom

I vaguely recall someone saying they *thought* that it's from a super early E36 318is. My car is a super late E30.

So, what are the ramifications of installing this into my ECU and going for it?
If the car starts, will I feel a difference?
Is this a risky proposition? Is it worth it?
Can anyone read this thing and tell me what it is?

It sure would be nice to gain a few horsepower for free.

You will probably have to contact Dinan. My experience is that they aren't too helpful on older models. I sent them an e-mail once asking about their sway bars for an E30 and never received a response.

the really sucky thing is I posted about this chip ages ago on e30tech, I tried to research my ollllld post and it doesn't turn up.

EPROM chips are just blanks, like empty video cassettes. What you burn on to them is what counts. No you won't hurt your ECU trying to run a program on the "wrong" chip.

heh I know what an EPROM is... I work in the Silicon industry

I guess I'll pop it in an see. Some electronics are more sensitive than others, and these ECUs are not cheap if you fry one... so I thought I'd ask in case anyone has done this before.

with some further searching, it appears this is no longer a mystery chip. it's from a 1993 318. the ecu should end in #990. if it doesn't apply to my car, it'll be up for sale, cheap. stay tuned.

I called Dinan today, no callback. Nice long-term support, eh?

My E30 M42 ECU ends in 175...

I want to publicly thank Dinan for the return phone call.

Not.
