Hey,
Is there anyone here, who is capable of calculating checksum on Nissan ZD30 Zexel ecu or knows a program, that works?
I have already tested with Ultimo, Winols, ECM Titanium, Lsuite and manually calculated by CRC16. Non of those works.
Have validated multiple times, that it must be checksum issue. Even if I edit only drivers wish map in one single cell by 1 mg
the car wont start. I wirte back ori files and car starts. What is even more confusing is the fact, that Rumpig on this forum has
successfully tuned these ecus without even touching the checksum. I wonder if it could be the difference between SW versions
manufactured for different continents.
I ll also add mappack if maybe somebody wants to tune same ecu in future. Should have all the basic maps found there for standard tune.
(If you can crack the checksum issue).
Thanks in advance guys
