Wierd maps and Checksum errod upon ECU resync

Post by Peace »

Hello everyone, especialy nistune support.
Recently i ordered a nistune type 3 board for my primera P10 94-95 JDM
I've downloaded my rom. And it was not like any others nistune saw. Finaly they say its most common to G20-P10 infinity.
Upon recieving my board ive installed it and my car runs fine. But i have issues wich not allow me tune my ride.
First of all, if I use G20_P10_SR20DE_512_E.adr file my maps looks tottaly messed, take a look

if i'm using P10-SR20DE_512_E_94-95.adr file everything seems fine

Using this address makes streaming mode trace maps right.

Another issue is that i cannot Sync my tuned maps to ECU.
When i start resync Nistune says Cheksum Error and closes consult connection.

I've tried turn debug mode on in configuration but no logs comes up in /logs folder of nistune installation.

I'm using com consult cable like this one

Could consult cable be a problem? all other software runs great on this cable and nistune connects to conslut without problems, logging is working, rom downloading is working. Resync from ECU to PC is working fine but when try to resync to ECU from PC "Checksumm Error".

Red alot of forum threads and recheked my ECU jumpers. Thats fixed the problem.

Everything seems works when i redone jumpers to CJ2 and installed new version of nisute.

The problem was due to ECU works on internal maps.
