TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

Thanks. Do you think it would be okay to combine both gauges to a single wire and run it to ignition?

 

I believe when I had my gauge I was using the washer fuse in the cabin with an add a fuss to get power with ignition on. My gauge randomly died and I haven’t put one back in.

 

Should be fine. The gauges do not draw much power.

I run my trans temp and oil pressure on a single circuit with a dedicated fuse.

 

Speedhut gauges has up to 4 on same fuse. At least that’s the wiring harness they provide when you order 2 or more gauges. I have 2 tapped on same add-a-fuse.

 

Much appreciated! @Murphinator @Scott B. @henryp

 

It's a 12v system from the truck. The little LEDs in the gauges and miniscule power to run the PCBs adds up to very little draw. You'll be fine to double up, especially off a bigger amp fuse.

 

Looking good! Sticking with the TRD tune long term? He did my tunes for my FJ cruiser! TRD Tune ECU will be just for CA smog

 

Thanks! Grabbed the TRD tune just to make the truck drivable. Will do the OTT tune once I add the rest of my mods. Y-pipe, exhaust, fuel pump, etc.

 

I want to like this gauge mount better, but I feel like I would get annoyed by it blocking the instrument cluster. I also don’t like the A-pillar mounts because it’s not stealthy and I don’t like more lights shining in my eyes at night.
If/when I ever get gauges, I’ll probably find a spot to put them below the radio and a/c controls or something.

 

There is plenty of room down there.

However, they can reflect off the passenger door window at night...

 

I can’t lose my cupholders though… I’d probably recess them where your radio is.

 

There is plenty of room there, and, most likely will not reflect off the window.

I do miss the cupholders...

 

This gauge panel by @loginfailed looks tits! Hope it gives you some ideas.

Yeah. I have my ultragauge on the A-pillar right now using the Spiker Engineering mount. I'm going to run this for a while but @SUMOTNK has got me thinking about that open space in the lower dash now...

 

Nice, that’s what I was thinking… and gauges that let me control the backlight similar to the dial on the dash that allows me to FULLY turn off the lights at night if I want (off-road, speed/rpm doesn’t matter when just exploring).

 

Finally got to turn the truck over and get it on the road. Good news, sounds awesome and feels great. Bad news, got the dreaded bank 1 and 2 lean codes. Now I'm chasing down a vacuum leak somewhere. Long term fuel trims are reading nearly 40 on both banks. Cleaned MAF, checked around AFE Intake, checked vacuum lines. All seems OK so far. Really don't want to pull off charger to check the intake manifold gasket but it's brand new so I don't see that being an issue. Any suggestions?

 

If it's the Momentum GT part of that is the MAF housing size. It's larger than stock and will require scaling. But I've never seen it 40% out.

 

It's the Magnum Stage 2. I may pull the MAF again just to double check. I'm not sure if this would have to do anything with it but I am running it boost referenced but everything at thw T seems solid. Same at the fuel pressure regulator. Everything is capped off until I install my gauges.

 

Yes, boost referencing the FPR will throw the fuel trims off a decent amount (in the positive direction) as it lowers fuel pressure when the manifold is under vacuum when the stock/TRD calibrated ECU's calculation assume it's fixed at ~43.5psig.

 

Ok. I'll switch it back over and see how it does, thanks!
