So im looking into getting a link ecu, It will work nicely, there is one thing though that i'm wondering. I know the link ecu has a PWM output, what is the control of that PWM can it be customized and controlled by certain engine parameters just like Fuel and ignition. The reason Is i have a VNT turbo that is controlled by PWM and if i can control the vanes via certain engine parameters that would be amazing and make it so much easier to set up. EG The Vanes open based on engine load RPM and boost, so at idle your closed so the exhaust will have an increased velocity rocket nozzle style, but as you mash the gas and the rpm increase the vanes open so its ideally in sync with the exhaust gas volume giving optimal spool, it doesn't have to be crazy accurate because in reality it goes from closed to open extremely quickly but a little control would be cool

 

Depending on what you're trying to do, it sounds like you can do this with any of the current crop of Link ECUs, the G4X & G5 lines, or even the older G4+ ECU lineup. You'll want to use an available AUX output to control your low current draw output device (can be a solenoid or normal or solid state relay), and you'll set up that AUX in the Link software as a General Purpose PWM output (GP PWM). The software lets you set up the X & Y axes of your PWM control table to be pretty much anything you can think of (e.g., RPM vs MAP; RPM vs. TPS, etc), and you can even include several conditions to enable or disable the AUX output, e.g., AUX is only active when coolant temp is above the number you set.

I'm running a Link G4+ in my single turbo FD, using one of the AUX outputs to control a fuel vapor purge solenoid just like the FD's OEM setup like this. Suggest you check out Link's customer support forum here: https://forums.linkecu.com They have an excellent support forum, and have been very helpful to me in climbing the learning curve with the ECU.

 

Awesome that should be perfect for what i need
