  1. Dear All, This post may not be related to tuning but more towards wiring problem but I am hoping that I could get some basic guidelines as I consider myself still new in the arena and still got a lot to learn I am currently using Link G4+ Monsoon on a 3SGTE ST246 engine on my Toyota MR2. Car was running great for the past few months until recently I could not get my car to start. After I did the basic check-up I found that the fuel pressure is '0'. Therefore my focus would definitely be the fuel pump. For your information, the wiring was not done by me but I am now learning to do such wiring myself. My fuel pump is activated from a relay that uses AUX 6 of the Link G4+ Monsoon. I try to run the test using PC Link and can hear the sound of the relay clicking but I don't hear the priming sound from the fuel pump. Then I try to directly run the fuel pump from the battery (12v current) to its connector and I can hear the fuel pump priming. For that, I concur that my fuel pump is working and is not the fuel pump issue itself. Next from the connector that I have disconnected from the fuel pump, I tested it with a multimeter. What I found that there is a current supply of 8v-9v to the fuel pump when the key is ON (after finish the 2-second priming that I have set at Link G4+). When I set at PC Link Software 'test ON' for AUX 6 which is the pump, the current supply becomes 2.8v-3v along with the clicking sound. Picture attached is as per my explanation. Picture #1 8v-9v before TEST ON fuel pump at PC Link Picture #2 2.8v-3v during TEST ON fuel pump at PC Link Next, I try to test all the fuses that I can have my hands on but all the fuse seem okay. As my logic and understanding of wiring, I don't feel its the fuse as there are still current flows to the pump but it just seems that the current is low for the pump to operate. As I mentioned above the wiring was not done by me, therefore, I try my best to detect the wiring with the limited knowledge that I have. I seek the advice here to guide me on how could i further diagnose and solve this issue myself. Your advice and guidance is very much appreciated.
  2. Hi @MGV101, I've been reading your thread with alot of interest. I am currently using the 3SGTE ST246 (Gen5) engine into my MR2. This engine originally comes with COP setup. In that case it is as similar with your issue. So what exactly your solution? What did u do to makes the A/C runs same as stock?
  3. Any updates on this? Did u manage to solve the issue?
  4. Why would you recommend engine running time instead of MGP, MAP or TP? Is it better if we take into consideration when the car moves?

    Thank you. Yes you r right. Problem solve!
  6. I'm also facing the same problem and confuse. As the theory state the hotter the air the less dense it is. I am using Toyota MR2 with 3SGTE ST246 engine. Being a mid engine car, this is car is known for it heat soak. My IAT sensor is place between the intercooler and the throttle body. The car runs well in a normal temperature (AFR of around 14-14.7). My location has an average ambient temperature of 35 degree Celsius. However, during hot restart in a hot day, the the AFR reaches 16-16.8. In that time the IAT can reach up to 55-60 degree Celsius at idling. when the car starts to move the IAT will drop and once AFR reaches 14.7 the engine runs smooth. Therefore i need to increase the fuel in the IAT correction table.

    Dear @Simon, Sorry i am actually quite new and still learning. So just to be clear.. 1) How to know that my unit run full scale? 2) Attached below is my wideband configuration table. . - And also i attached the calibration table provide in Link G4+ help manual. 3) So based on my configuration table with reference to the table provide by Link G4+ manual, the low value here refer to 'Low Voltage' or 'Low Lambda'? In my configuration table, i register AnV4 Error Low = 0.05 and AnV4 Error Value = 0.000lambda..Which should i corect it?

    i have one of those..Zeitronix ZT2. Is there away from me to recalibrate it? because i receive ECU Fault Code 20: An Volt 4 below Error Low value which refer to my wideband sensor
