lity Posted December 21, 2018 Report Share Posted December 21, 2018 Hi I recently installed the the G4+ , found the following not working properly: Where do i correct the settings in the ecu for the below following: 1) fuel gauge meter is not reporting accurately. The fuel warning came up. Upon refuelling - it max out at 35 Litres. Altezza fuel tank capacity 60 L. 2) Traction control - light blinking. Can't turn it off. How to disable from the ecu? 3) Snow - how do disable from the ecu? 4) heater - how to disable ? 5) idling with air con - rev is bouncing between 400 - 1500 rpm .. thxs Quote Link to comment Share on other sites More sharing options...
Adamw Posted December 21, 2018 Report Share Posted December 21, 2018 It needs to be tuned in modelled mode for the fuel gauge to work correctly. I have attached a map set up in modelled mode. I dont think you will be able to get the traction control working & light off, our test car didnt have traction control so I suspect there will be something missing from the data streams causing this. The snow button is connected to the ECU and can be used for other functions such as launch control etc. It is received into the ecu as CAN DIG 1. The lamp should still turn on and off with the button as far as I know. What do you mean by heater? It is not controlled by the ECU. You will need to tune everything properly before idle control will work well. G4+AltezzaLink Turbo Modeled Fuel (2).pclr Quote Link to comment Share on other sites More sharing options...
lity Posted December 21, 2018 Author Report Share Posted December 21, 2018 Stupid question- where is modelled mode in the menu? Quote Link to comment Share on other sites More sharing options...

lity Posted December 23, 2018 Author Report Share Posted December 23, 2018 thxs. I still don't quite understand - how this impacts the fuel gauge reading - please can you advice further. Why wasn't 'modelled" made default ? It would make sense that we would want the fuel gauge reading to report accurately ... Quote Link to comment Share on other sites More sharing options...

I still don't quite understand - how this impacts the fuel gauge reading - please can you advice further. For whatever reason Toyota decided to have fuel consumption data as part of the gauge control. I suspect it possibly varies the gauge needle to reflect a "distance to empty" rather than just a fuel level. The only way the ECU can calculate fuel consumption is by using modelled mode so it knows fuel pressure and the size of the injectors etc. 16 hours ago, lity said: Why wasn't 'modelled" made default ? It would make sense that we would want the fuel gauge reading to report accurately ... This was something we learned sometime after we designed that ECU. I believe the ECU's have been shipping with the modelled map I attached above installed for some time now. The current PC link still has the traditional map but that has been changed to a modelled map in the next release. So possibly someone loaded an old traditional map back into yours?

lity Posted December 26, 2018 Author Report Share Posted December 26, 2018 OK to reconfirm - just need to run in modelled mode for the fuel gauge to report the fuel level accurately ? the injector size ; is this also required for accurate reporting of the fuel gauge level ?

JMP Posted December 26, 2018 Report Share Posted December 26, 2018 injector size and characteristics are needed for the modelled fuel model to work well Quote Link to comment Share on other sites More sharing options...
lity Posted December 26, 2018 Author Report Share Posted December 26, 2018 my tuner updated injector size as 320 instead of 365 , as the tuner found the fuelling values were too big via 365. 320 allows finer fuel tuning. Quote Link to comment Share on other sites More sharing options...
Adamw Posted December 27, 2018 Report Share Posted December 27, 2018 I think your tuner sent me your map earlier and I found it had a setting wrong in the CAN stream, I have sent him back a copy with the setting fixed, hopefully fuel level will now work as expected.
