Hi Scott & Simon, Refer to the above mention, I have received ECU send back by Link and install back to the car everything work fine, only the fuel gauge is still not working correctly, it only drop quarterly. as mention above, in order to make the Altezza fuel gauge work correctly, we need to change the fuel equation mode to moderate. I have send my car to my tuner, we tested once we switch to moderate mode we can't start the car, like no fuel supply to the engine. My tuner ask me to check with link and request for a based map with moderate fuel equation mode setting. My current Spec as below Stock Engine 3SGE G1 with Greddy Trust Turbo Kit Warbo Fuel Pump Work Stage 1 Fuel regulator set at 4 psi Sard 530cc Injector dead time 1.10 m sec parts no 63516 changed stock O2 Sensor to Bosch wide band sensor with Depo controller Sard 68c thermostat Can I have your Email Address so I can send your my current based map and some of my log file. Many Thanks. Joseph Yong Email [email protected]

Raediyusof, that is 2 connector on the sensor one is 12V the other is 5V Signal output should connect to your ECU an volt input the sensor body is ground.

HI Scott, I have send back my ECU as per NZ Customs term, you should receive it within this 2 days.

Hi, I have done the registration to send back my ecu as per the info your given, do I need to wait for any confirmation before I send back?

Noted thanks

Thanks for the info, when I switch the VVTI aux pin to other aux output and config the selected aux output to VVTI will the ecu know that I have move the pin ? Do I need to perform any other setting for my VVTI pin relocated?

Noted with thanks. Will arrange to send back around next week.

Thanks Scott. I can arrange to send back my ecu for firmware upgrade anytime, can you provide me the address? Since I'll send you the ECU will you be able to help me set the modelled fuel equation setting base on my current ecu setting? Will get my tuner to tune once you return my ECU.

Hi can anyone provide me some info? I am using G4+ Altezza Plug in ECU, and I have replace my E-throttle body with aftermarket throttle body, and now wanted to add a ISC device to control my idle, may I know which ISC should I choose? 2 Wire or 3 wire ? And my AUX 1&2 currently is set for VVTI control can I use other AUX to wire on the 3 wire ISC?

Hi Simon, I would like to check with u, is the new firmware solve the Altezza Fuel gauge issue? If not can you give me some guideline so I can arrange with my tuner.

Ok thanks for your info.

Hi, need to check if I upgraded my ecu firmware will it effected my existing setting ? Do I need to tune my car again?

Hi Simon, I can only try on the setting part, and dyno I Can't make it cause my tuner is busy till after Chinese New Year.

Hi Simon, No problem for me to perform any testing, if you willing to provide me a detail guidance.

Hi Scott, my setting now is traditional fuel equation mode.

Thanks Scott , the oil press and oil temp is working now, the body of the sensor is ground. So that only 2 wire + body ground.

Thanks Scott, I have changed a new cluster and has confirmed the cluster got problem. May I know is the fuel guage issue solved? Can we just upgrade the firmware to solve the issue?

Thanks for the info Dave. Just to confirm, I am using the sensor that I attached. With 2 cable 1 ground and 1 signal , so I just connect the signal cable to the AN volt ( oil press) and AN temp (oil temp) and ground to the engine ground.

Hi I have done the obd 2 wiring from the altezza plugin ECU can/rs232 port socket , but I don't know how to setup the CAN setup to make it sync with my OBDLINK device. Can someone expert here give me some guidance? TQ.

Thanks for the detail info JMP

I have connected the round connector to USB port for tuning, can I connect obd2 from picture show socket? Can I have the pin out for this socket ? And do I need to install 120ohm resistor at both end or only 1 end?

But in the help file didn't mention the 5 pins can/rs232 socket pin out, and it is a must to connect the 120 ohm resistor at both end as mention in the help file?

Hi can anyone show me how to wire the OBD2 socket connection from ECU CAN Bus 5pins socket to the altezza original OBD2 socket? I am using Altezza G4+ plug in ECU

Hi Scott, I have install the oil temp and oil press sensor may I know which channel I can wire on?

May I know how to wired the 6 pins bosch wideband LSU49 o2 sensor to the Altezza plugin ECU?
