[OVERSPEED]

You may have a CKS error

[oskarra]

the problem is why the car start if i disconect and conect the battery...
if i have a cheksum error the car never start, and this car start the first time i conect and disconect the battery.

[CustomCars]

This type ecu can start with problem checksum. But only once one.
Even with good checksum and some mess in file older ecu can start.. but most time only once.

[oskarra]

so , what can i do?
try to put original file?
or remap one more time?

[CustomCars]

1. check chksum. MPPS dont make checksum automatically for this ecu !
2. if not work remapp again

[oskarra]

how can a i check cheksum?
with win ols?
could you explain me how can a i do it?

[CustomCars]

any software ols ok too, can make it manually by mpps to, ad bottom you can find checksum button first it needed modiffied file, then orginal and save checksumed modiffied to new one and write

[oskarra]

so you want :
1.-conect mpps16 on car and make cheksum with mpps16?
2.-write the mod file on car.
3.-make cheksum after write on car?

[oskarra]

mpps16 do not let me to insert original file on car.
The program tell me that its not posible to write original file.
could you give me a email and i send you a video or photos.

[oskarra]

mpps16 co not recognice my ecu.what can i do?

[oskarra]

it says the last time i can conect:
Flash program attemps :1
Flash program Counter: 1

EPROM AM29F800

This is a NOREAD file and has been encrypted.



PLEASE I NEED HELP.

[OVERSPEED]

disconect battery and try again, remove dash fuse works some times... if it didn?t work make it in Boot.

I had problens with MPPS making CKS in ME7 when messing with engine torque monitor issues, ECM didn?t make it work, only OLS worked

[CustomCars]

100% checksum was bad that's why ecu can be reached anymore. Try with disconnect battery then try write checksumed file.
If not work only boot mode or programmer.
Mpps no needed be connected to make checksum and make it only once.

your file was not crypted. noread don't change nothing at OBD work with ecu.
