Well, I started pulling my bits out to sell (FCD and S-AFC), and I noticed that the Fuel Cut Defender has not been plugged in all this time! The unit was installed on the dash when I got the car, it had the power wired in properly but the signal wires to the ECU were just dangling.

They had round connectors on the end, but I'm pretty sure they need to be spliced into the loom like the S-AFC wires. The guy that installed it probably ran everything up until that point, then realised there was nowhere to plug the wires in and so just gave up.

I saw the wires there when I installed my S-AFC last year but didn't think they were anything important and so didn't bother tracing them back. I thought they were speaker wires for splits or something.

I would bet $20 that this is the whole cause of my surging problems. Consarn it! Oh well, the PowerFC should make me a happy chappy.

    • 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?

    • 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/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.
