Hello there

I was thinking of getting into tuning(learning) and i thought of getting the practical reflash tuning course

I thought of going with uprev since i have the tuning cable already but i think its best if i go with ecutek

My only issue is, based on researching my car don't have wideband and if that's true i won't be able to put my knowledge to the test

How do i confirm if my ecu really does, and if not whats the best way i can learn and practice my tuning if i dont have AFR access and no easy accessibility to local dyno's?

My car:

Nissan 350z 2004 (LHD) Manual Transmission

ECU number: CD505

03-04 350z didn’t have widebands. Later models do. You can still practice idle and light throttle tuning with these sensors since they are accurate near stoich, then you’ll want widebands to tune full load operation.

I know on uprev theres an option on external sensor but cant find much thread on forums with decent information on this because im gonna need it regardless and dyno is kind if hard where i am at

I do havr a 2008 HR tuned by the Goat rsenthalpy so i dont wanna touch that car either even if i have my tuning file but if i switch to ecutek i will lose my uprev license

Decisisions decisions 💔

Ill still get the course and start learning tho
