michael Posted October 9, 2009 Share Posted October 9, 2009 You have a "I" - it's near your right knee under the dash IIRC. Link to comment Share on other sites More sharing options...

Nic Posted October 9, 2009 Share Posted October 9, 2009 (edited) The 2JZGTE VVTi is OBDII, all non VVTi Supras are OBDI Edited October 9, 2009 by Nic (see edit history) Link to comment Share on other sites More sharing options...
merckx Posted October 9, 2009 Share Posted October 9, 2009 From what I remember there is more than one version of OBDII , not all fault code readers will work on the Supra. Link to comment Share on other sites More sharing options...
JustGav Posted October 9, 2009 Share Posted October 9, 2009 From what I remember there is more than one version of OBDII , not all fault code readers will work on the Supra. Yup, and the OBDII on the supra is the odd one and not the usual one either. I've forgotten which protocol, but something like PWM1412 or the like, I'll dig it out later.

Nic Posted October 9, 2009 Share Posted October 9, 2009 The R-VIT will work on a VVTi TT, but there are limits to what information it can monitor.r-vit-type1.pdf Link to comment Share on other sites More sharing options...
andyx187 Posted October 9, 2009 Author Share Posted October 9, 2009 can the port be changed or is there a third port or can i piggy back straight of ecu with a lead Link to comment Share on other sites More sharing options...
Nic Posted October 9, 2009 Share Posted October 9, 2009 (edited) I believe you can get OBDI to OBDII adapter cables, how much actual useful information you would get from the ECU and whether the R-Vit would understand it I don't know.

carl0s Posted October 9, 2009 Share Posted October 9, 2009 I thought it was the OBD-1 that was unusable with anything because there was no actual set standards on OBD-1, but that OBD-2 is OBD-2, no ? Link to comment Share on other sites More sharing options...
jackso11 Posted October 9, 2009 Share Posted October 9, 2009 If you change the ECU to a new plug and play, mapable ECU....can you then have an OBDII port fitted? Just a thought, would be useful if you can because I can then plug into my car-PC Link to comment Share on other sites More sharing options...
