Ok, I'm getting close to the point of powering things up (side tracked by body and suspension work). If I don't have aux 9/10, which of the current Link lineup do you think would best fill my needs? G4X XtremeX? Other than the e-throttle issue, the G4 Xtreme I have does everything I need. Since I have a stand alone e-throttle module, would a G4X StormX be enough?

Any way to make this work?

Having said that, at one point I thought my Xtreme red had outputs for e-throttle at 9/10. I then discovered the Xtreme silver had these outputs specifically for e-throttle not the red. I made the (hopefully not false) assumption this was because of the current draw of the e-throttle and in the red these were not able to supply the current necessary, hence the external module requirement. This topic is not really covered in the manual. My manual does not have that line. I take it this means my ECU will not drive all the outputs I need. My manual does not distinguish the Xtreme red from the silver. This has led to my confusion about the e-throttle capability. With VVT alone, I cannot use Aux 1-4 for signal 1. Looks like I cannot have VVT and e-throttle let alone EGR. Is this correct? Everything I had read online about the G4 Xtreme suggested it would work for this engine. The information necessary to make this determination is not readily available unfortunately. I wish I had known this before making the secondary purchase of the external e-throttle module

I haven't got that far...still wiring, haven't accessed ECU through software. Wiring loom has aux 9/10, manual says it has aux 9/10, but I haven't accessed them. Just reading the manual which came with the unit. Says it's the manual for G4 Xtreme and Storm. Says Storm has 8 aux outputs, Xtreme has 10.

Hello, I'm wiring up a Subaru EZ36 to my G4 Xtreme Red. To manage the e-throttle, I also have the e-throttle module. I am wiring that in now and have run into a problem. In my engine wiring I have Aux 1-4 running the four valve timing solenoids. I have Aux 5-8 set up as a stepper motor to run my EGR system. I left Aux 9 and 10 open for the e-throttle (how it is wired in the manual for the model with built in e-throttle..?Xtreme Silver). The wiring instructions for the module I recently purchased however say signal 1 must come from the ECU's Aux 1-4 and Signal 2 must be from Aux 5-8. Is there a way I can rectify this conflict and still have my valve timing and EGR? Thanks in advance.

Thanks Adamw! Thought that was the case but not sure. Didn't know about those boosters, will investigate more. Looks like a cost effective solution

Just to confirm required modifications: I'm using my G4 Xtreme to manage a subaru engine. The vehicle I am putting it into requires modifications to the tachometer (older vehicle, tach input originally from distributor I believe) to accept the input from a similar vintage (mid 2000's) Subaru ECU were I using that. I'm assuming the output of my Xtreme is the same as the Subaru ECU output and the modifications to the tach would thus be the same. Is this correct? Thanks in advance...

Thank you very much Adam! Problem solved!

Hi, am wiring my G4 Xtreme to run a 2008 Subaru EZ36 engine. Making good progress but am having trouble with the AVCS actuators. Not clear to me how to wire them and the engine manual I have doesn't help either (solved the TPS, EGR, and AVCS sensor wiring for me; not clear on the actuators). The Subaru engine harness has different wire colours for each of the connectors on the actuators so it's not clear if one is power or one is ground. The G4 manual tells me which outputs to use for each actuator but it's not clear to me which connector of the two in each actuator it goes to and what to do with the other 4 connectors. +12V? Ground? +8V? Help much appreciated.

Thanks! Can DI1 be tasked to something else?

Hi, wiring up a Subaru EZ36 to a G4 Xtreme. I'm a little confused about what to do with the cam timing sensors. The G4 wiring manual asks for Trigger 1 to be crank sensor, and Trigger 2 to be RH intake cam sensor (the side with cylinder #1...I think that's correct!). However, the manual also suggests wiring the cam position sensors in the D1-4 positions for quad cam engines with VVT. Should I split the wire from the RH intake cam sensor and run one tail to Trigger 2 and one to D1 or can I leave D1 or Trigger 2 empty? Thanks in advance...

Thanks Adam! Will purchase external module. I'm digging out my soldering iron and getting ready for wiring...

Hi, I have a G4 from 2009 which I plan to use to run a 2008 Subaru EZ36R engine. I am a little confused about whether it can run the Subaru's drive-by-wire throttle. Everything pointed to it being able to but I am just reading the installation manual included with the PC Link version 4.10.2 (the last/latest update for G4's) which says only the G4 silver case can do this. Mine has a red case. Anyone know if my unit can run the e-throttle? I guess this begs the question whether I have the correct version of PC Link. I'm not sure which one to choose. I assumed the PC Link software would update the firmware on the ECU so chose the latest and last software version for the G4. Am I wrong on this? Should I be downloading the PC Link version for the firmware on my unit? How do I tell what firmware my unit has? Sorry these are all rudimentary questions but I am new to Link and not sure how the firmware and software interact. Also, really want to be sure my G4 can run my engine before the wiring begins! Thanks in advance Sorry, meant to say my unit is a G4 Xtreme red case.

So, don't need a huge amount of computing power but a decent screen a good idea?

Hi, I am hoping to use a small laptop or tablet for tuning only (no apps or programs running in background, wifi off). What are the minimum requirements to effectively tune using the link software?
