Hi, I'm new to the forum.
sorry for my bad english.

I illustrate my problem:
I have a renaut scenic 1.9 DTI that mounts an ecu bosch msa 15.5 (0281010077),

I performed the immo off following the procedure of "immo universal decoding 3.2", total MOD
Now the car starts but its performance on the road is not good,

following the other procedure in "immo universal decoding 3.2"
the car does not start.

I tried to follow the procedure in nyo4 2014,
the car starts and the performances are excellent
but if I turn off for more than 30 minutes the car will not start anymore.

Does anyone have any other solutions or advice?

thanks in advance for your availability.

As I remember,after you write immo off file in 24c16 eprom, you need to short circuit leg 7 and 8 on eeprom. Otherwise, immo will become active again. See the attachment, it could help you.

The only instructions I have are you need new eprom, and do these other two mods to ecu shown in the pictures

i seen this be for when you load the modified hex dump immo off file, lock it so ecu dont rewrite the file again

I used this solution with the mod of nyo4, but I do not remember what kind of memory I used. in the mod of Universal immo decoding besides this there is more to do.

I used this solution with immo Universal decoding, but the car has no performance, I do not remember what memory I used.

Inside is 24c02 or 24c04. You need a new chip because the one in the ecu dont have WP pin. make your immo off write it on the chip lift pin 7 and solder it to pin 8. The other way is to use emulator.

Hi friend
immo off for this typ ecu msa 15.5 work 100% with software immo kiler
but friend change eprom 24c02 or 24c04 or 24c08 lift pin 7 and solder it to pin 8.

Fill strings 0x30, 0x40, 0x50 with FF FF FF....
Use new eeprom 24C02WP, 24C04WP, or 24C16WP

Good luck

I solved the problem, with the procedure of immo universal decoding I used a 24c16 memory because the file to write was 2 kb,
Now the car starts and the performance is excellent.
Thank you all for your cooperation
