Magnuson Supercharger Install / Modification – Crib Notes

[DAVECS1]

That is my favorite movie scene of all time! Damn that is so cool.

Not to break my own arm patting myself on the back, but the small pulley tune is the bomb. The sound alone is worth it. I keep the exhaust valve cracked at take off to battle the jumpiness at tip in. The supercharger just sings. Had a guy ask me if my jeep was electric, LOL

What's the ball park cost on getting one installed? I'm really dying for some more power in the gladiator.

Dave, Can you give a bit of a description on how you are naming your files to help figure out which tune is for the trans and which is for the engine? GladiatorSCEVONP1, GladiatorSCEVOT82, etc.

I have an automatic tune which includes the engine and auto trans tune.

And I have a manual transmission tune, of course that just has the engine, but the engine tune is different for a manual (long story)

I had just versions of the EVO tune out for manual and automatic, but I have had to change as now I have a pulley and non pulley tune

So EVONP stands for evolution for No Pulley 1

My pulley tune has continued on with evolutions and so has the manual tune.

Couple updates here.
1. Have worked on the fuel surging during cruise in 7th and 8th. I am not sure if the surge is all gone, but it is improved.
2. I have changed the throttle gain. This is gonna be real wonky after the initial flash. The control will need to rifle through the new gains and get them loaded and it will smooth out. This is to help with the step off.
3.Alot of timing changes, this is to help the step away, and it also smooths the part throttle acceleration through the gears
4. Some cam position changes to gain a bit of power and also smooth acceleration
5. Torque Demand tuning to help the 7th and 8th gear cruise as it was struggling to get in 8th sometimes
6. Shift schedule tuning to help smooth early gear shifts and the engagement of 8th gear lockup

I have carried the changes to the manual file, but as usual, I have had no way to test it. It should be safe, but I would test it before actually going and using your jeep everyday. Be happy to look at data and help correct any issues.

A little info on reading and flashing files.
when you went to read your file you need to hit gather info as I have in the picture below

When you do that it will give you the option to read the engine and transmission tune

Once you have it read, you can then follow the Instructions above to copy the tunes I have supplied
Then you can flash the new engine and transmission tune. I flash them one at a time as the combo flash sometimes hangs up.

I got the bearings pictures. Getting the old ones removed is not that easy… Did you use a press?

Yes, I used a press and some large sockets. If you screw them up they are common and can be purchase at the auto parts store

Hey Dave, just so I’m straight. The SCEVONP2 is the file to use with out the pulley upgrade. Right?

PM Dave about the Pulley Tune. He hasn’t made this public…

One other question can you save an MVPI2 file as an older series 1 MVPI file?

 

[DAVECS1]

There is no difference between MPVI and MPVI2 files. I use both interfaces quite a bit.

The "evonp" tunes are what everyone who does not have a pulley upgrade should use. As stated above the pulley tune is not public.

Thanks Dave. The must be really giving me the run around. I’ve had more problems with getting it updated. I’m very new to this. So, if they say I listened. I was told they had to be converted to work!!!

The flash tool you received with your supercharger uses .rtd files qhich are flash files Magnuson has had commercially locked to the HP flash tool they send with their supercharger.

So I guess it all boils down to this question that I need to ask. “Please excuse my ignorance”. Is there anyway to remove the RTD file and replace it with yours?
