Hi all,

Does any one know a program to calculate the checksum from excel ECU from a Patrol GR 3.0 DI from 1999?

I've read somewhere that doesn't need checksum, but i've tried with no luck, i end up putting back the old chips.

Thanks.

Do you think this might be due to chips used? i've used AM28F010B-90JC. Original chips are NM27C010VE120.
