99 euro ecu support

[The-Stig]

Hello all, just a polite inquiry, i have a euro spec 1999 ecu, I realise that chrome will not run on this ecu and i was wondering if there was going to be any support for it?

I would like to be able to access the fuel maps and timing etc and was wondering if anyone has a rom and xml files that may be compatible to try.

noobie to this side of things so done lots and lots of reading and trying to make sense of it all.

i have tactrix, flashecu and evoscan already.

You guys do some awsome work.

Regards.

The immobilizer is the reason why chrome doesn't work on your ECU. It's a unit external to the ECU itself. That needs to be disabled.

Hi thanks for the reply, my car is a 1996 Gto TT currently on the hybrid system. There is no external immobiliser from what I know?

Oh well then you should be good.

Oh well then you should be good.

So am I able to flash chrome directly or am I some sort of guinea pig at the moment ?

[Greg E]

The cars I got feedback from were all stock 99s. So you get to be a Guinea pig.

Lol that's reassuring, if it don't work would I be able to revert back to the original ROM?

Willing to share all information if anyone is interesting in any r&d.

Waiting on a harness so I'll repost once ready to rock and roll.

Thanks for the help dude.

Read the image on your ECU and save it before writing Chrome onto it.

Do you know how to so this? If not, I can give you a copy of the stock euro rom to flash back on with the immobilizer disabled. You won't be able to do much with it though nor does it have the chrome mods.

I have the 99 euro ecu.

Had some troubles with the immobilizer. Blackstealth helped me disabling it.

Greg made the defenition file for me with everything you need. Fuel map, timing map etc. Doesn't have everything of Chrome I guess but I think it has everything you will need honestly.

Works for me anyways and I'm happy with it. If it doesn't work out for you then I can send you my files if you pay 10$ to Greg. (for the def file he worked on)

Looks like Greg is the man!

I already extracted the rom from my ecu (you can have it if it helps anyone analyse it etc).

Would love to look at Greg's version with the def files, let me know how to make the payment and I'll send it over.

I'm not really interested in the rest of the chrome etc at this stage I only want to look at the fuel maps and timing data just to get me off the ground.

Any help is greatly appreciated.
