Nav software update: Will it Affect Uprev?

Jordo! · 01-03-2014, 01:42 PM

Okay -- whew. Thanks for clarifying!

Should I explicitly tell them anything to that effect?

As in "ONLY update the nav software -- so not do anything that alters the ECU", or will they just look at me like I have three heads?

On a related note, is the same true for body ECU stuff -- that alterations to that software are independent of the EFI ECU?

Cipher lets you access the bcm, so I think at least some of that is shared.

Does the Nav have a separate control unit?

I thought that it did (along with the body), but since it can probably all be accessed from the OBD port I wasn't sure what aspects of the programming code are shared and changed together vs. independently, hence my concerns.

Who's your tuner?

Keep it simple, just tell them only to update the navi

I'm pretty sure it does. I was under the impression the nav brain was in the back of the car with the amp for the Bose.

THat's what I thought too.

I'll make sure to tell them that only nav updates are to be made -- no touchy of the powertrain ECU.

Thanks, gents
