Loaded that tune into a spare G4X Xtreme and ran it on a sim and all the injector pulses appear to be working, is it something you can replicate?
Happens every time I run the car. I have no idea what's the issue because the injector clicks with I do an injector test. So I did not bother checking the wiring. Aside from switching everything around I even applied a pulse from an external injector tester and the cylinder would come to life.

can you attach a copy of your tune saved from the G5 software please.
go back to G4X PCLink and select ECU Controls -> Update Firmware

Updated link g4x Xtreme to latest firmware and using g5 software, then lost cylinder 3, appears to be an injector. ECU is wired in an Evo 4, stock harness. Checked all the usual, spark, fuel, injector etc, injector clicks during injector test.
How can I roll back firmware?

Probably just 2 power grounds will be ok provided the wires are decent size. You would likely only be putting 6-10A to ground with everything maxed out.
You dont need both sensor ground pins connected.
B5 will need to be powered. Note you are going to need to add a bit of extra stuff to control the main relay for ECU hold power. Something like below should work I think. Mitsi pin numbers on the left, Link ecu on the right:
So for the grounds I can do the following?
Pin 13 --> pin A25
Pin 26 --> pin B25
Pin 92 --> pin A24
Also, I'm not seeing info on Evo shielded wires and how it's handed in the harness, so what should I do with pin A7 and B17?

I came across a good deal on a Xtreme ECU, for use in an Evo 4, 4g63t engine. I want to take my time and build a new harness as this would be my first time building a harness. So untill then I'm trying to use a breakout board to wire the ECU into my existing harness. I have a few questions about this, each link ECU connector has 4 grounds but the Evo harness has 2, can I split this? Each link ECU connector has 2 sensor grounds but the Evo harness has 1, can I split? The 14 volt on connector B, do I still wire this if I'm not using E-throttle?

A voltmeter or oscilloscope would, but if the ecu says no signal then it means it is receiving less than 1.5V from the trigger sensors. Since both stopped working at the same time then it is more likely the common 12V supply or ground to the sensors is missing. Start by confirming you have 12V and ground on the correct pins at the sensors.
looks like my crank sensor is gone, voltage on signal wire not changing when i turn over the engine. which 2 pins do i check for resistance?

was driving and the car died, now when cranking the trigger 1 and 2 signal in run time values stays at no. So 2 questions, is there a better way to check to see if the ecu is seeing signal and if the crank has no signal will the cam sensor also not show a signal? i know some of the tests like continuity to the ecu pin etc but im just kinda worried and dont want to have to remove the timing cover to check the crank sensor yet.

If you mean the quick tune function, then this is designed for steady state tuning on the dyno, there are no filters. If you are worried about over-run fuel cut then just turn it off when you are tuning.
Based on the settings available I kinda figured it was designed for steady state tuning. Was hoping I could just leave it on where driving around on the street and have it collect valuable data. Thanks
