Need Help Finding a JOBD Scanner for Live Data (MAF/Fuel) for Vitz Thesis Project! - Toyota Yaris Forums

Hi all,

I’m an engineering student working on my thesis , and I’m stuck. I need to pull live MAF sensor and fuel data from my JDM Toyota Vitz (2004, OBD2 connector but uses ISO protocols, JOBD?) to simulate airflow for CFD analysis of swirl generators I’m designing on the throttle body. The goal is to see if increased turbulence affects engine power output.

What I’ve tried:

Techstream cable : Failed to communicate with the ECU.

ELM327 adapter : No luck (probably because it’s standard OBD2-only).

I’ve researched scanners like the ANCEL JP700 (claims J.OBD support) and Autel AL519 (but I read it might not work for J.OBD). Can anyone here recommend a scanner that definitively pulls live data from a JDM Vitz using J.OBD?

Requirements:

Must support JOBD protocol (non-standard OBD2).

Needs to display live MAF and fuel trim data .

Budget is tight (student discounts or affordable options welcome).

I’ve heard mixed things about the ANCEL JP700—does it work reliably for the Vitz? Are there alternatives? I’m desperate for advice, as this is blocking my thesis progress.

Any help is immensely appreciated ! Happy to provide more details.

Thanks!
