Hi guys, not sure if anyone else has experienced this but I've got an Uprev tuned ecu with NATS disabled in my Z , it's a 2004 from South africa ( we only got the Grand touring models here from 2004-2008) , reason I needed another ECU was that our local DE's in south africa don't have the Rom capacity for map switching and ARC features, so long story short I got an ECU from Canada ( all hardware from donor car being same as my Z) , my car runs amazing , all features working and no noticeable issues besides a CEL that shows up all the time. Scanned the code , getting a P1610 - which is NATS malfunction , so my question is why would I get this code given NATS is disabled via uprev ? So I've cleared the light before and tested this a few times , It stays off after clearing but as soon as I remove key from ignition, it's the same fault all over again , so it's a stored issue , no idea the cause ? Hoping perhaps someone has insight or experience with it, I'm just pedantic on having a clear dash lol.

 

Whoever did it for you doesn't know what they are doing. You have to disable NATS, and bypass the 1610-1615 codes

 

Hey man thanks for the reply , by bypass you mean turn the DTC's off yes ? Because I've heard that Uprev removed the DTC disabling function with their newer Rom editor versions, I'm personally not too clued up just yet but I'm learning slowly 🙈

 

Has to be done by a protuner
