TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

No worries my friend. We are all here to help each other. Everyone brain farts every now and then.

 

@crashnburn80 what's the latest, how's the truck running today?

 

WOT testing on the way home yesterday and the way to work this morning with zero issues. Truck runs like it never happened. Haven't yet had the chance to investigate more yet.

 

About the same as I get. 13 city, 15-16 hwy.

 

Great to hear. Last month I had a couple of days where the truck would pull timing at WOT, no other symptoms. Thought it was bad gas but it went back to normal before I added octane booster or changed anything.
Running theory is the knock sensor went into defense mode then decided everything is ok after all, been fine ever since. Hoping yours is the same.

 

+1

 

Depending on which sensors we are talking about, doesn't one side have a longer wire than the other? For instance when I installed my URD ypipe I switched the sensors unknowingly, and then when I went to install my roost ypipe I had to install them on the correct side for the wires to be long enough.

 

This is what i was about to say as well, i thought they were side-specific

 

These are non issues really as the connector is the same for both upstream sensors, HOWEVER, their connector location makes doing simple sensor swaps an absolute PITA to do and the risk exists of pulling the wires from the connectors and good luck repairing the issue if you do. That's why to me, it is best to check their general voltages at idle and their amperage output. Combined, both readings will let you know if the issue is sensor based or if it is unrelated to.

 

The rears are slightly different lengths. You can check the fronts to ensure they are the same part # but I am pretty certain they are the same part. If there is any difference in the front censors, the only difference would be length of wire.

 

No worries. I have extenders in the garage for my URD headers that I can use if needed. However, when I went to drive home the light was off and no issues. I am sure it may be symptomatic and will check the voltage.

 

The light off means nothing. The issue will likely return and will likely return with a higher frequency as time goes on. These trucks can see fuel trims of as much as +-15% and never trigger the light on so just because the light is gone doesn't mean it's still not running lean. You may want to take a look at the fuel trims again just to make sure.

 

^^This^^

Why I like my dual afr gauges.

 

Waiting for clutch masters Black Friday sale for hydro bearing. And lc engineering for some head studs. Anyone sees or hears anything let me no.

 

if you do urd is having a sale right now.

 

same.

 

Lol yeah that’s above average for me

 

Ditto on the CM hydro... I also need Spec to have a decent sale.

 

11-12 all city. 14 all highway. 16 if kept below 70 MPH. Not horrible considering the performance it has and all the weight it carries from topper, bumpers, winch, tools, roof racks etc.

 

Mmmm. Spec
