  So what's the advantage of this method over having one solenoid on the top and one solenoid on the bottom? Like if I wanted to remove pressure from the bottom and allow the valve to shut quickly by venting the bottom. I looked through your other videos and I don't see that you have a video on the other dual 3 port method. Very well explained video though

• 
  @greenshortsperformance4722 ай бұрын

  You wouldn't ever want to dump the bottom of the gate. That's the balancing pressure coming from the manifold to tell the gate to open when the spring force is met by manifold boost. Two things open the gate, backpressure and reference pressure (bottom). 2 things close the gate, Spring force and applied pressure to the dome from the mac valve(s). So in this case whats nice is how fast 2 3 ports work and the ability to manipulate a pressure curve very quickly and hold a target rather than just applying a little more or less to achieve a target boost. This method would allow you to do something like say 20psi on the starting line to build boost, then quickly dump some to manage launch power then ramp back in to a plateau and even change the plateau for gear changes etc. a single 3 port can try, but its not every going to be as good or fast and will be very wasteful with co2 or onboard air to achieve the same goal

• 
  @LegitRaceCraft2 ай бұрын

  @@greenshortsperformance472 The bottom solenoid would be set up to only dump between shifts. the pressure is removed from the bottom of the spring only then. I may switch to this method though, I just finished running lines and configuring my ecu, but i ciuld easy switch. I'm not running co2, just turbo pressure. Would I need to run a dome pressure sensor for this method? In my haltech i can set up dual solenoids but this is only used for co2 (i asked haltech a while back and that was what they said). So I set up a generic output to control the second solenoid. It makes sense to me that I can run it from boost pressure instead of co2 though.

  Just wanted to give you some feedback on your suggestion on my fuel prime-crank knock, results....It works thanks again, no more start up knock! 2 more questions if you don't mind, you mentioned checking the timing old school with a pointer, have you seen many LS7s with the crank trigger off? in the process of rebuilding my 7 with AHP ported heads and BTR sg 4 V2 cam, vid up on my channel for entertainment. What value do you put in for air temp Vs timing? I have a little retard dialed in after 115 deg and retard up to 5 deg at 160 air temp. the C2 ls7 I'm working on has the air cleaner next to the radiator, not good but no room on a C2? Thanks for sharing all this cool tech!

  Your timing adjustments are fine. They'll all be a bit different but its good you're thinking ahead on them. As far as checking static its never a bad idea. from GM they're usually very close. If you ever have the wheel off or you have an aftermarket crank id definitely check. I once had a machine shop install a wheel 92 degrees off. That took me a minute to figure out

  Love your channel, question: 66 Corvette 570 HP wet sump crate motor LS7, FAST 102 intake and TB, AHP heads redone, mill .030 .040 MLS head gasket, CNC port. Terminator X, redoing the timing and fuel map, starting off from max 24 deg, down to 21 and checking data logs for knock, all good on acceleration but we now get an intermittent knock on startup, timing goes to 33 deg, 100% knock and retard table kicks in then back to idle 18 deg and runs fine, the knock is only 1 audible knock on first 1 second of cranking and start up run and that's it, no more knock. tried reducing cranking timing from 15 to 5 deg no change, tried richer target air fuel, no change, the trace goes down the middle pink area like you have and transitions up to idle, tried pulling timing out of the data log trace and no change, it seems the idle and timing goes high right at first fire up, starts quick and runs fine.......have you ran into this issue before? O, one more data point, we are at 5,000 ele, cranking PSI went from 170 to 208 after the head work, guessing we are around 12-1 now? Thanks in advance for any input!

  I was able to apply this to my drive by cable setup. Basically I opened the throttle blades with the screw on the side of the throttle body instead of making the DBW motor do it for me. I opened the blades up until I saw the IAC position drop to just above 0%. Then I recalibrated the TPS. Then I checked that my timing was close to matching my target timing. This told me that the ECU was not trying to reach target idle speed by either compensating for air with the IAC or trying to change timing.
