Piggy backs
 

I dont want to reflash my stock ecu due to warrenty. But just for a random noob question does anyone have any experience with this in the Z

Uprev is your best bet.


You can switch between stock map and your other maps.

You don't want to reflash the ecu but you're ok cutting and splicing wires for a piggyback??

seriously tho, uprev's the way to go

I have gone the piggyback engine management route before. there was no wore splicing needed just plug in some harnesses. despite that the driveability wasn't so great.

for the record it was a turbo xs utec for a 05 350Z.

just go with a ecu reflash, can't go wrong with osiris.
