TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

Possibly super rich. As others said, likely that timing is pulled drastically as well. Won't know the exact AFR until the gauge is in.
For timing though, the Scangauge can display that. What does it display at low RPM WOT?

 

The very instant I hit it, it hits like -5 for a split second but then goes to like 11 degrees advanced and climbs from there to like 24

 

Ding ding.

 

So have a buddy drive while you stare at the timing. Does timing advance increase rapidly right when you are feeling (turbo boost)?
Sorry Tor, couldn't resist!

 

Low end fuel map then I'm assuming

 

I would say the reason you're not feeling any power at the low end is because the ECU is pulling all the timing at low RPM. It's probably massively rich at the low end as well.

 

gimme a minute to find the map

 

Heres my R4 fuel map.

 

I've heard y'all talk about the 7th injector as well as snow performance's meth injection. URD's 7th injector inputs fuel, while snow performance uses a water methanol mix. Is there an advantage to running one or the other on a forced induction engine?

 

I believe meth cools more then fuel from a 7th. Water can absorb more heat

 

$460 from Snow. $585 from URD.

 

$408 from Amazon is what I did. AEM. I got the pump installed today, the rest tomorrow.

 

Oh damn! Where are you planning on installing the nozzle? From what I read on Snow's website, their pump starts and stops flow at a preset boost psi... does it run a vacuum line off the boost port on the SC for reference?

 

That is an option, but I got the one that sprays based off the MAF. Comes with this little controller.

Any opinion on braided lines vs high temp nylon?

 

It’s been a while since I’ve messed with the R4 software. Am I remembering correctly that the default value is 10? If that’s true then number below 10 richens it up and higher than leans it out?

 

This^

He 2nd's the first quote.

Good to have, but without corresponding AFR's, it doesn't having much meaning yet. Is that Split Second tuning?

The timing being retarded to what you saw at -5 is the issue. That should be the inverse.

 

Went back and found my own post.

So on your map @HamerMan yours has a lot of really low numbers. Wouldn’t that be pretty rich?

 

There is advantage and disadvantage to both.

Advantages:

Water/meth has much higher latent heat of vaporization. (It cools way better)
Raises octane for even more anti knock properties.
Cleans intake tract and possibly piston crowns.
Can be run on virtually any engine.

Disadvantages:

Water/meth tank needs frequent filling
Separate system so more parts to potentially fail
Separate system so have two systems to tune
Possibility of meth being corrosive to aluminum parts.

7th injector advantages:

If you have a system/ecu that supports it (UCON) its plug and play when you get the tune loaded.
No second tank to fill

Disadvantages:

Not as effective at cooling vs water/meth
No octane benefits

Thanks to @TRON for some of this info. I had asked him about it long ago.

 

Thanks crashnburn80 for helping last night get my pulley swapped! Now for some roadtrip testing!
