*Closed* 20% Off Supercharger Group Buy 2nd Gen 4.0 Engine

Good info. Thanks! Even if I think that's a stupid setup on Toyota's part.

 

Well, not really, its actually helping your truck out a bit. Your engine probably takes the better part of 4 hours to cool off anyways, and that just runs the coolant a bit to accelerate the cooling. If youve ever popped the hood after driving around in boost, especially on hot days, that SC is steaming hot, so I don't mind moving the coolant around a bit more when its off.

 

I'm familiar, since we have multiple forced induction vehicles, but I don't think this is necessary. My GT500 gives off MASSIVE amounts of heat and my wife's BMW 335ix isn't far behind when we park them, but neither of them do this. Even if it was necessary when the truck is hot, it's certainly not when it's just sitting there at ambient temp. For that, I'll stick with my original "stupid" assessment.

 

The place where Magnuson says to tap it is a bad location IMO. There's not a good reason for the coolant pump for the LTR to be running each time the LDP comes on. I've been meaning to change mine but haven't gotten around to it.

I went on vacation for a week back in early December and my truck wouldn't start when I got back. It sat for 3x that long pre-supercharger and fired right up. It's the LTR pump that killed it.

Unless you go on vacation and leave it sitting for a week or two.

 

Water pump turning? Intercooler water pump? No, it's will not turn. What you hear is the evaporative canister pump. And it's active only few hours after shutting the engine down.

 

False. The Supercharger coolant pump gets tied in to that system check so it kicks on for a few seconds every couple of hours.

Sorry, I didn´t noticed there was 1 page more discussion.

Weird thing, I didn´t known that, I thought that it will test after 5 hours and that´s it, but maybe it continues then. Here is the explain of the evap system working: http://www.fjcruiserforums.com/foru...l-tank-1gr-fe-evap-system-troubleshooting.pdf

I haven´t connected my IC water pump below that ECM fuse, it´s connected from a different source and switch, so I have not this problem.

 

Cheers then! Seems like you did what 90% of the rest keep saying we shoulf probably do!

 

FIFY

 

so i should remove the tap? or unplug battery if parked in storage? from time to time, i dont drive truck for 3-6 month

 

Move the tap to another circuit that comes on with ignition. That is what I plan to do if I ever remember to do it when I have free time. The tap is only powering the relay itself, not the actual pump. So whichever circuit you chose to use shouldn't really be affected much. Relays generally draw 250mA or less.

Or leave it alone and just disconnect the negative cable if you're going to let the truck sit for a lengthy period of time.

 

For you taco guys having bd tune problems is the ecu cal id you have now the latest from trd or an outdated version?

 

Mine was listed as what the most current that toyota had in their system. Thats why they said they couldnt flash anything. Cause the bd/magnuson tune snuck in like "oh hey, Im an official trd tune, dont mind me" and tech stream bought the bull.

 

Re-reading that, do i sound a little bitter?

 

Ha, don't blame you!

 

Here, I'll say it. Fuck Bully Dog. Although it's probably Magnuson's fault.

 

Jberry with the ninja quote. Regardless, the hand and the instrument both played their part.
