Hi all,

Just a quick question...

this may sound bodgy but its only for a test...

Fuel cut on an R32 Gtst, is there a wire from the ECU that i can just cut to stop it?

Or i have to go buy a Fuel cut defender?

Becuase i think it may be the problem with my car ATM.

All help is Appreciated.

spewing about that man,

as far as cutting a wire to remove boost cut, i dont think its that simple unfortunatly i found an ECU Pinout here http://www.rb20det.com/ecupinout.html had a quick look and only thing i could suggest is to modify the signal on the injector wires, but i wouldnt be game

On the Skylines with unmodified ECU, the first obstacle is a programmed mass airflow limit cut. The airflow meter is not at the limit, and if you modify the signal the car will run lean and probably detonate. The only wire you can cut is the speed signal to remove the 180kph limit. Turn the boost down.... and check the computer diagnostics for error codes in case there is something else wrong. If you want to keep the boost, you will need to have the computer replaced or re-programmed.

      Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

      Leak from Tokico BM50 Brake Master Cylinder

      The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/
