land rover discovery 93c56 dash help please

[jpsl]

Hi does any one have a clean dump for the discovery 93c56 dash, i belive i messed mine up by reading the chip wrong then it filled with ff somehow, so i can not get the orginal read from the chip
i need it to read 172516 miles if possible,
i have attached what i thought was the original dump
but i dont think i read it correctly as i have rewriten the file to the chip but the milage stays blank on the dash any advice will be great thanks

You can try this one,

thanks but it reads 107136 miles instead of 172516 think its swapped milage reading for km or vice versa
ive tried to change the km many times but it seems to write what it wants or random changes in upa or my script is buggered in upa as its always wrong
what do you use to edit the milage in the dump, and thanks for your help

oh its a uk disco if it makes a diffrence by the way

[jpsl]

not sure what i am doing wrong if i read your file in carprog online i get 172384 miles but when i write to chip and load clocks i get 107136 miles, am i writing to the chip wrong or is it a setting in upa , what do you think

[stoyanov]

172384km = 107136miles

Try this one

[jpsl]

Ok thanks will resolder and try ASAP and let you know thanks again for your help

[jpsl]

Thanks it’s close lol it’s 10 miles out so still flashing but I think I have to write to both the clocks and the bcm,
do you think if I write on both it will sync and stop flashing or is there a software apart from nanocom that can sync them together?

[Diagcar1]

You need to do BCM!!

[jpsl]

Hi Yeap thanks, do I do the same small chip or is it the big square one in bcm as not sure which one to do ? Thanks ;)

[Diagcar1]

Yes have had that one to.

[jpsl]

I’ll iupdate soon ;)

[jpsl]

Well I’m struggling to read it lol none of my adapters seem to work.
so if I copy the pin out from a MC68HC11 and conect rx, tx, reset, and mod A and mod B to GND do you think it will read and write OK. Or am I on the wrong path ? Thanks

[Diagcar1]

Don't know if that's a problem, as I can recall I read it in circuit.

[jpsl]

I’m back but no luck connecting to the chip, what mc68hc11 are you using I’ve tried a few but there are many is the mc68hc11k ok to use as I’m bit stuck now :(

[jpsl]

Ok I’m using mc68hc11ph8 I’ve lifted 3 pins from the board but it’s still not reading it I’m not sure what I’m doing wrong I’m coping the same way in the upa pdf but no joy, I have lifted 3 pins from another guide and ground pin mod b but still no joy I am getting
reading 1 error found range 0 - 2ff
any idea where I am going wrong please?

[jpsl]

Sorry any one got a pic or a guide on how to connect and read via upa please?

[jpsl]

Horay lol I’ve done it had ground on wrong pin,
any way now to learn how to sync the 2 lol

No need to sync, first do dash look ad exact miles, program that in BCU.
