A T-fitting in the line or a 1/8npt drilled and tapped into the side of one of the aftermarket injector holders for those with the bypass injector setup. The little block and banjo fitting above would be nice too.
Forgive me for not reading through the thread again !!! Just wondering how this worked.. I"ve got my MS and a few other items and just want to be sure I have all the items I'm going to need.

If you are using Lambda/FV control only then the pressure sensor is not needed by the system. it's only used for the eWUR control.
However, logging system and/or control pressure is still certainly useful and can be done by adding the pressure sensor to the existing lines with something like the below

The alloy Lambda head I have here has a test port on the top system pressure gallery that feeds the cold start injector but nothing dedicated on the lower chamber.

Yes! mechanical/hydraulic constant flow injection can be managed by a modern EMS

Looks familiar, had Len (BoxterGT) build mine then added a gauge.

Hi everybody!
Hi Steve!
Could You please explain to me this?
The DPR value in mA I see on tunerstudio gauge is what ecu asks to pressure regulator or it's the real value of the current? I hope the question is clear.
I noticed a few days ago empty spaces when I accelerate rapidly from idle, done some datalogging and I see negative peacks in dpr values, even -60 mA.
Normally I should have an increase.

the DPR Ma shown in the gauge is the total mA value the system is commanding (request)

if you are seeing negative spikes there is something in the control values dropping the commanded fuel amount or causing the fuel cut to trigger

overspeed or overboost maybe?
how stable is your RPM signal, are you getting spikes on the RPM input during acceleration

Since this thread is still rocking here's few snaps of my FCIS modified rear electrical panel about ready to go back in.

As the last picture shows, I extended the "shelf" portion of the rear panel to accommodate new goodies while still leaving space for the rear wiper relay, rear window heater relay etc. I have run additional power to the panel and will be delivering it to the dedicated fuse block via a relay mounted on the square adapter in the LHS corner or the panel. Now, mounted on the rear panel I have:

-Microsquirt
-6 position ATC fuse block
-Relay adapter 911 round hole to standard modern square adapter, my own design I may start selling once I've road tested the design
-2x3Bar pressure sensors for MAP and constant baro adjustment, on a 3D printed bracket of my own design
-Boost control solenoid
-3D printed terminal strip for connectivity with ignition and sensors

Not shown is the knock sensor controller, still remains to be mounted.

Beautifully done, with extra points for no zip ties

lol thanks! admittedly my lacing skills aren't what they were, but it looks ok and is solid.
