Hi everyone,

I have a 2000 Sportivo and it is missing the cooling duct to the ECU box. I believe a number of owners leave this off, but I would like opinions as to why we need to cool the ECU? By the way, the entry to the ECU box has been blocked off and the car runs really well.

Regards.

Bruce

Sportivo or Celica?

I'll assume Celica since you posted int he Celica section. The cooling duct, I assume, is there to provide fresh air to the ECU box as the ECU, in Toyota's infinite wisdom placing it in the engine bay, it gets nice hot air from the engine bay. The cooling duct makes no difference and we have never run it on the Celica at here. It is probably there as 1 of the test mules got a hot ECU once, so they made sure it wouldn't be a problem in mass production.

      1989 Hilux Low Voltage

      I,m pretty sure they run an external voltage regulator, mounted on the side in the engine bay, its been a while now so I'm not sure if the original had points inside which pit, stick and so on. Get yourself a fully sealed electronic one from the wreckers, as chances are someone has updated to cure symptoms like you are having, even one from another Toyota model eg Corona, will do, If yours is the original it will have a big black top on it, No more problems This is what you need; Buy Jaylec Voltage Reg 12V Denso Ext 026000-4050/4051/4070 For Toyota In589 15-867 Online | Rolan Australia

      DIY Update GPS Maps on Toyota Corolla Ascent Sport 2017

      Hi everyone, I own a 2017 Toyota Corolla Ascent Sport based in Perth, Western Australia. My car's navigation system currently runs on iGO Primo software (version 9.12.14.545514). I'm looking to update the maps and keep the entire system updated. I understand that the recommended method is to visit a Toyota dealer, but I'm interested in exploring if there's a DIY way to do this. Could anyone guide me through the process or provide any reliable resources or links? Here are the details of my current setup: Car Model: Toyota Corolla Ascent Sport 2017 Location: Perth, Western Australia Navigation Software: iGO Primo 9.12.14.545514 Specifically, I'd like to know: Where can I find the map update files that are compatible with my navigation system? What are the steps involved in transferring the map updates to an SD card and updating the system myself? Are there any risks or considerations I should be aware of before attempting a DIY update? I’ve looked through the user manual and some online resources but couldn’t find a comprehensive guide. Any help or pointers would be greatly appreciated! Thanks in advance! Best regards,

      Upgrade from 2012 to 2023

      I have recently bought a 2012 Prado and was wondering if i could buy a 2023 strat write off prado and upgrade both interior and exterior so all the functions from the 2023 works regardless of the newer features and buttons. I'm planning to upgrade not just the exterior, I'm also planning to upgrade the interior dash and stuff as well.

      Towbars

      I went to my local Toyota Dealer for a nudge bar and tow bar for my 2017 AWD RAV4 and was told by their part's department was told "parts no longer made." Looking at aftermarket (ECB, Haymen Reese and ARB) but hesitant because sellers can't give 100% guarantee that parts will fit GLX facelift model.

      Concerns about Fuel Consumption in Kluger Hybrid

      I have the same issue with my 22 new Hybird Kluger. I also found my (grande) new Kluger has missed 220V power point and camera view on central mirror comparing with same car in US. This clearly are the short cuts to Australia Toyota customers which is unacceptable.
