Dumb question. Is the vacuum on the 24x setup the same as the standard LT1? Im trying to see what ports and such needs to be capped off. I have no A/C or Heat if that matters. I was looking at this diagram below. I just dont like surprises and would like to know.

Do I keep the canister purge valve and EVAP solenoid?

24x does not care in the slightest about vacuum, other than MAP.

You need a dedicated line for BOV, FPR, and EBC. Otherwise, cap it, or plug it.

AFAIK, 24x will not run EVAP, so remove it all, and run a breather line off tank.

Seems you may be able to run the EVAP purge but not vent, weird?

Either way, I would ditch it.

I was looking at the link you sent. At the bottom of the chart. Im guessing thats the low fuel level light.

Those are LS1 PCM signals, not the LT1 side of things, so don't worry about em. PCM does not see fuel level AFAIK. Its a cluster to tank only connection.

So what all vacuum ports on my intake need to be capped off?

You need three. Pick three, cap the rest.

Assuming you have a BOV, FPR, and EBC.

So any 3 will work? I do have a EBC, BOV and FPR

Any three will do the job.

Hey bud, if Im not putting the car into boost for a while, Im prolly not gonna hook up my EBC, can I cap that port off? Also do I need to actually run a vacuum for the BOV upon startup?

Sorry for all the questions, my 1st time doing this.

Why do work twice?

Hook it all up correctly now and be done. I use my EBC as a boost/vacuum gauge so its nice to have hooked up IMO. You can always set all the settings to zero and it will be like you are on WG spring only.

I would hook up the BOV for sure, is it 100% needed for start up? No, but again, work twice...
