Hey man, I must again thank your for your guidance. Had to replace the sensor ground, also noticed a burnt AC fan connector and replaced that as well. Any further electrical problems and I'd replace the entire harness. I believe the car is now ready to be tuned with all parameters set correctly. The only thing I can find documentation on is how to setup knock control for this version ECU.

Finally got this sorted, turned out to be a faulty Cam sensor. The CEL comes up ever so often and it's always Voltage above High value on the MAP, IAT and TPS I think I't may be best to have the car rewired as I tested the Boost Solenoid for voltage and got 12v from both terminals and my speed sensor works intermittently. I swear, I didn't anticipate these issues and figured finding the link in there was a blessing but with what seems to be bad wiring... IDK
-
Ok, I will turn off the additional IAT, just not sure how to identify which one the ECU is using for the IAT reference The TPS works. So, having cleared the codes I finally decided to do a WOT run with the car and strangely I hit the RPM limit at 4500 RPM and the log shows a jump from 4500 to 7800 which is the configured RPM limit. I'm thinking it may be trigger related but haven't gotten around to doing a Trigger Scope... sigh!

This worked perfectly. The car seems to have two IAT sensors configured... there's one just before the TB and another via a tap on the head. I cleared the code and all seems well but are there any benefits to doing this dual IAT setup?

Hi finally got chance to attempt to identify the firmware version via the ecu information screen but it looses the connection and I get a response indicating version 0.0 When I go to the firmware updater, it reads the firmware as 4.10.2 (see attachement) The error code is visible at the top but I'm still unable to maintain a connection to the ECU What do you suggest?
-
Thank you. This worked, I can now see the error is related to a temp sensor, however, I'm being prompted to update the firmware then it seems I lose the connection. I've looked at the firmware update videos for the G4+... assuming the procedure is the same should I proceed with the update?

Hello Everyone, I recently purchased an 04 JDM STI and got a CEL. Upon investigation I realised the ECU is not OEM but carries a board with the following markings: PCB Rev 1.2 Serial# 16816 I tried connecting it to the PC via the USB cable with the latest G4+ software and it says "the ECU is too old" How do I connect, check and reset the codes causing the CEL and further, can any Link ECU tuner perform future tuning (I understand there is a code of some sort required for tuning)
