Who's installed the GIAC 2.0T In-Tank Fuel Pump Upgrade?

So any resolution to this?

I am going Revo stage 4 and everything is done minus the lpfp upgrade. I can't find a definitive answer anywhere.... Can I swap the lpfp with the TTRS pump leave the original control module and wire in the PM3 unit? This is supposed to be a "plug and play" solution just really can't find any confirmation

I opted to go PM3 rather than GIAC's dual lpfp.

The PM3 helped raise and keep actual pressure above 4 bar with the tiring oem lpfp still installed. But the PM3 and oem controller works with the oem pump and the TTRS lpfp. You can wait and upgrade it to a TTRS when you see pressures drop below 4 bar. I plan to integrate the TTRS into the oem housing and sender when this happens because of the following.

The PM3 and oem controller will plug in to the TTRS upgrade...you just will not have correct fuel gauge readings with the TTRS sender installed. The readings will be slightly off...meaning it won't read completely full and may run empty when it sayd you have 10 or 15 miles to go. I found this out when I had the TTRS installed for a couple of years.

Here is a diagram from Torquebyte. Hopefully this will clarify how things are hooked up. Yes the OEM controller is still used for signal but not for current anymore. That signal is passed to the Torquebyte unit which replicates the signal and will now supply the current to the pump via its big fat wire connected directly to battery (max current).
