TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

thats at idle. what is it at when your at MAX MAF g/s ?

 

I’m trying to figure this out. I’ve never looked at it myself before.

Maybe, I should stop posting pics until I get a handle on it... lol

 

Wow! 11.6. What size pulley is that?

 

2.55

 

Ahhh, the dreaded 7.5. That means the datalog is inaccurate because the UCON and computer aren't playing nice together. Try restarting the program on comp, start truck, then connect USB. Check the gauges on the program (the first page) you should see real numbers. If you see afr's or any other data that is at 7.5 then you need to re-start the process again.

 

OK, that makes sense. I was just about to post that both fields are flat across the chart.

That explains it.

 

If you get a lot of erroneous data. Here is what I do and it works just about every time.

-Unplug the UCON USB cable.
-Start windows, let it load completely.
-Wait a full minute.
-Open uTune.
-Start engine.
-Then plug in the UCON USB cable.

 

OK, thank you. I’ll try that. I think I’ll wait until morning. I leave the house at 5:00 AM. Less traffic to contend with.

 

The 7th is working. I wasn’t thinking. I have the files from Sat to look at. That’s the file that I sent to Scott Sat morning. Not sure why he wouldn’t look at that?

 

@ThomasMore66

Sorry to be short before. I was learning decipher this software...

2.55 with the 7th injector. That, I can now see, is indeed working.

 

yup .. its looks like its working.
Im assuming you upgraded injectors ? 65% duty cycle at 5200 rpms.

 

Indeed. 640 cc

 

Noob...I don’t think so.

 

That pic looks very noobish.

 

Lol! I was trying to point out the “NOOB” decal on the cab corner. Not very noticeable in the pic I guess.

 

That looks just right.

 

Alright, I sent Scott the pic showing that the 7th is working.

Unfortunately, it is not working properly.

His reply:

“It’s adapting 30% - same as what is commanding thru aux…”

Snorkel is fine as long as you never set a P0101 code…


7th injector is not hooked up properly.


Need to see how you have it wired – the standalone harness that plugs into the back of the UCon that is next to the USB cables…

“
Yes, the system is running beautifully…


My bet is the harness isn’t pushed in all the way at the injector or at the UCon…


S”

So, I’ll pull the UCON tomorrow night. I’m sure I just didn’t get it plugged in all
The way.

 

That would be good too. Better even

 

No, I saw it. I was just looking at all the armor, the gear up top and the spare driveshaft. I wish my rig was that noobish.
