Pete Posted July 12, 2006 Share Posted July 12, 2006 I know this has been mentioned before, and I thought it didn't work properly, but according to the site this software will work for "all Toyota Supra's, even 1998 models". Any tried it? Link to software homepage Link to comment Share on other sites More sharing options...
Chris Wilson Posted July 13, 2006 Share Posted July 13, 2006 The VVti has none compliant OBDII , I have tried umpteen scanners on it, none work, it's not even wired conventionally. Link to comment Share on other sites More sharing options...

Pete Posted July 13, 2006 Author Share Posted July 13, 2006 I just re-read the text and think I got the wrong end of the stick entirely. In general, Asian, European and Chrysler vehicles are ISO-9141. The few exceptions are 1996-97 Toyota, most are VPW, 1996 ISUZU is VPW, all Toyota Supra's, even 1998 models, are VPW and 1998-Newer Chrysler 300's, Intrepid and Concord are VPW. All Ford, with very few exceptions, are PWM and all GM, with very few exceptions, are VPW. What does VPW mean? I guess by this are they saying Supra isn't ISO-9141 which we already know so it's not going to work and I wish I hadn't even mentioned it.

Justin Posted July 13, 2006 Share Posted July 13, 2006 Blimey, accurate AFR would be nice. Especially if you could record a road test too. Link to comment Share on other sites More sharing options...
Pete Posted July 13, 2006 Author Share Posted July 13, 2006 I sent a message I don't know what VPW means. I was hoping to use your system on a Toyota Supra 1997 VVTi model, can you confirm in plain English if it will work or not? Just got a reply... What OBDSCAN Unit did you have ? GM , Chrysler, Toyota use Interface call VPW, ISO-9141, and KWP-2000 Interfaces that talk to Vehicles. And Ford Vehicles use PWM Interface( from 96 to 2003), but from 2003 Ford started to use CAN Bus Interface for Ford F-250 and F350. And by 2005 to 2008 all Vehicles that sold in North America had changed to CAN Bus Interface. Now, Chrysler use VPW, KWP-2000, and ( CAN Bus Interfaces for Chrysler 300 Model ), and Toyota use VPW, ISO-9141, KWP-2000, and CAN Bus Interface for Toyota Lexus and PRIUS. That is why we have OBDSCAN + CAN Units, and this Unit will work for all Vehicles with an OBD II from 96 to 2007 and beyond. So he's saying it will work? I'll ask for confirmation again I think.

Kranz Posted July 16, 2006 Share Posted July 16, 2006 KWP-2000 is Key Word Protocol I think.... Can is + and - can wires in a twisted pair communicating every sensor & control system throught the two wires via a can bus system. VPW??? Variable Pulse Width???

Pete Posted July 17, 2006 Author Share Posted July 17, 2006 Oh well... Pete In that case I don't think our OBDScan will work either. The Japanese models are not OBD-II. Best Regards Dan Harrison Harrison R&D Link to comment Share on other sites More sharing options...
Gaz Walker Posted July 17, 2006 Share Posted July 17, 2006 Nah we tried a number of things to try and get it working. In the end we bought an proper JDM diagnostic machine, boy does that work Gaz. Link to comment Share on other sites More sharing options...
