Tank Posted July 25, 2022 Report Share Posted July 25, 2022 Hello folks, Planning to get a link ECU for my build. It is a 2000 Lexus GS400 Supercharged with a Vortech. I am under the impression that I will have to retain my stock ECU for the throttle and VVT-i system to function. since main engine control will be handed over to the Link ECU wont the stock ECU go into limp mode with all the 'missing' sensors and limit throttle?

Adamw Posted July 25, 2022 Report Share Posted July 25, 2022 The link can control the throttle and VVTi no problem. But I suspect you may have the story slightly wrong. Wouldnt the bigger problem that may require the factory ecu be the auto trans and dash in that car? Tank 1 Quote Link to comment Share on other sites More sharing options...
Tank Posted July 27, 2022 Author Report Share Posted July 27, 2022 Yes, you are absolutely right the Auto trans would pose another problem, but the car has be manually swapped so thats one less issue to deal with. Apologies for not mentioning it. For the dash I was also seriously concidering a Link race dash. The only thing really standing in my way is finding a sutable dash adapter/bracket for a nice clean look. So, the current line of recommended Link ECU's for my build (Fury, Storm, Extreme) would have no problem controlling throttle and VVT-i? Thats great to hear. That eliminates a lot of potential issues I was not lookng forward to dealing with. Perhaps the Person/dealer I spoke with has outdated information. Anyway, thank you for the update! Do you guys have a wiring schematic available for the above mentioned ECU's VVT-i 1UZ-FE for viewing? Speaking of ECU's are there any plans to upgrade the Link Thunder to the G4-X line? Thanks again for the info! Quote Link to comment Share on other sites More sharing options...
koracing Posted July 28, 2022 Report Share Posted July 28, 2022 The Fury and Xtreme can both do DBW but the Storm can not. Tank 1 Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 28, 2022 Report Share Posted July 28, 2022 I would probably lean towards an Xtreme for the 1U. The Fury would also do it if you wanted built in Lambda. Coils would be wired in wasted spark pairs with the Fury since it only has 6 ign outputs. Wiring for the Toyota clutched throttle is in the help file, Wiring Information > Input Signal Wiring > Analog Inputs > Throttle/Accelerator Position Sensors > Specific TPS/APS Applications > Toyota Clutched Electronic Throttle Wiring for the VVT and coils is in the help file: Wiring Information > Output Wiring > Variable Valve Timing (VVT) Solenoids > Specific VVT Applications > Toyota 2UZFE VVT Wiring Tank 1 Quote Link to comment Share on other sites More sharing options...
