Supraman Posted May 23, 2009 Share Posted May 23, 2009 Hi, I have a 1993, GZ, Aerotop, Auto, TT. Does anyone know if there was a change to the ECU for this model and later models? I am talking about pin layout, wiring, etc. Thanks for your help Quote Link to comment Share on other sites More sharing options...

JustGav Posted May 25, 2009 Share Posted May 25, 2009 Yes, VVTI's are different. Quote Link to comment Share on other sites More sharing options...
SteveR Posted May 25, 2009 Share Posted May 25, 2009 Auto/Manual ECUs are different, TT/NA are different, non-VVTi/VVTi are different. Mix those combinations together and I think that's all the different types. (e.g. Auto TT VVTi) Quote Link to comment Share on other sites More sharing options...
Supraman Posted May 26, 2009 Author Share Posted May 26, 2009 I was concerned that there may have been a slight variation to the auto ecu (pre-VVTi) i.e. toyota did an upgrade/change (to the 1993 MKIV ECU) prior to the VVTi introduction. Thanks for the replies. Quote Link to comment Share on other sites More sharing options...
JustGav Posted May 26, 2009 Share Posted May 26, 2009 Don't believe the auto tt ecu non-vvti has any variation, ie one unit since inception till VVTI. Quote Link to comment Share on other sites More sharing options...
