ecu corrupt via flat laptop

[gazza19800]

hi wondered if there is anyway around this , was downloading files from the ecu when lappy went flat .
so unplugged everything now car wont start i believe it has corrupted the ecu file and immobiliser code

is there anyway of fixing this via 1.3 limitless cable or 2.0 one i have both or is it new ecu time ?
but then still immobiliser will need coding wont it?

thanks for anyones help

Have you tried flashing a rom back onto the ecu with the imobilizer disabled

[gazza19800]

dont know how to do that yet as just got software today and leads , trust this to happen i was rushing about sorting some other car out and lappy had switched off
how do i disable imobilizer ?
plus i havent got the rom it never got to finish downloading but i dont mind starting from a std rom , car was 410 bhp but power delivery was absolute rubbish so i was going to map it . i have mapped several big power cars and never had unstable software tbh ,so i should have paid more attention
thanks

Evo8 gsr ?

[gazza19800]

yes

[gazza19800]

i cannot connect to ecu via 1.3 cable . seams like immobiliser is stopping power to ecu
not bothered if i loose immobiliser etc

[gazza19800]

tried ecu flash too
same happens

[gazza19800]

is there anyway of powering ecu to get a rid of immobiliser and flash with new rom?

[evonut270]

download ecu unlocker from aktivmatrix then run it before you open ecuflash.then try to read the rom file again

[gazza19800]

i will try that
thanx

[gazza19800]

it part uploaded rom file thou i know it takes ages first time . i went to do something else and lappy was off when i cam bk . i knew it would corrupt it but i couldnt do a thing

gazzatry what i said and see what happens.

[gazza19800]

it wont connect at all ,so wont flash ,unless ecu unlocker works .
it like no live to ecu as avcr wont come on eithier , i am going to chase wiring to to see if avcr is live via ecu

what happens when you turn the ignition on?does the ACVR not power up?

Are you sure it has not blown a fuse as the avcr will take its feed before the ecu

[gazza19800]

if it in same feed to ecu then i would make sense really
as immob will be killing the live to ecu

[gazza19800]

avcr doesnt do owt just dead
i press immob and lights flash but no start .
and no connect to ucu

The avcr should still power up with the stock imobilizer on is your alarm arming and disarming with the remote fob

[gazza19800]

i will look tomorrow hope its simple like that but doubt it .
stock imobiliser red light on colum goes out when pressed flashes if not

gazza

does the engine management light come on?

[gazza19800]

when?
before immboliser pressed?
when 1.3 cable atatched to ecu dash light flash

[gazza19800]
