Superchips cortex tuner 3950

[(S.M.R) 101]

Alright this dude is selling this 3950 cortex for a hell of a deal he has only had it for 3 months and sold his dodge truck he still has the receipt from when he bought it.

I asked him if it was VIN Locked and he said it was not.... But I'm not going to trust someone I have never met before.

How can I test this thing before I buy it.. Where can I see if the VIN is locked?

he is asking 200 for it but I talked him down to $175! and then I'm going to sell it to my boss for a lot more than that.... because he's an ass hole.. :Moon:

Thanks guys

Just plug it up to your truck, it will tell you if it's VIN locked or not. That's a damn good deal if it's not!

[(S.M.R) 101]

yeah I know dude.. I might just keep it for myself

[(S.M.R) 101]

Alright Morgan and or David I just threw this cortex in tonight to test it out.. Maybe one of you can answer me this

Everything worked as suppose to but the shift from 1st to 2nd is rather rough and it kicks pretty hard

Does that sound normal to you?

[abn1985]

Need to change your shift points

[BMRbrnSNRbrd]

Well, first off, congrats on the tuner!

Second, yeah, lower your WOT (I assume you were wide open?) shift points. If it's the normal 1-2 check what shift points settings you're using (i.e. stock, user, SC).

[(S.M.R) 101]

Ok so I guess the guy never did a update to the Cortex since he bought it so I downloaded all the updates and hooked it back up at the preformance 91 and the shift is a lot smoother but there is still a little kick to it when it kicks into 2nd but a lot smoother..

and yes dave that is only in WOT

How do I change the shift point in WOT

[myoung84]

It could be the reduced amount of torque management. If it's more of a smooth kick it's normal. Try driving it a while and see if it softens up. Also, if you decide to keep it, I would buy the transmission tuning package, it's worth the $40.

When doing the advanced tuning, there are options for rev limit and wot shift points, as well as tire size, MDS disable, etc. I would start with 6200 rev limit and about 6000 1-2 and 2-3 shift points.

Congrats on the tuner!

[(S.M.R) 101]

Thanks Guys.. Even tho I already had one this one was a STEAL and could not turn it down.

Thanks Morgan I was not going to get into the trans tune stuff but I think with this one I will so I might need some help along the way from you guys... If you don't mind

[myoung84]

I think you will like it, especially as much as you drive! I'll help as much as I can with tuning. Check out this link, it has some nice starter tunes on it. The 08 folder has a couple of tunes from Sil, which should be pretty good. You might try PMing SilsHemi on DT and see if he can send you his latest tune.

Ok when I go to the SC update page it does not give the option for the transmission tuning package?? am I missing it somehow?

[(S.M.R) 101]

Ok and what does this mean it says "Locked Programmed OK" and gives the Vehicle ID and then that is the last 9 of my vin but don't know what the Vehicle ID is???

[myoung84]

That's odd. You still have your truck programmed, right? Is your VIN showing up in the update software? Do you see the other options to download/purchase like TPMS disable?

I'm not sure where it get the vehicle ID from, but Locked Program OK just means it's locked to your truck.

[(S.M.R) 101]

It gives me the option for Vin Unlock TPMS and off road package whice has been installed as well as the Data Accquisition which is installed

[myoung84]

That's weird. I'd call up SC tech support and see what's up. 888-227-2447

As long as you have your truck programmed and VIN locked (Which you clearly do in the pic) it should show up.

[(S.M.R) 101]

Thanks morgan I'm giving them a call now

[(S.M.R) 101]

DAMNIT! there not open

[(S.M.R) 101]

Well the guy told me that he bought the package about 1 month after he had it.. I know you can't transfer from truck to truck but might that have something to do with it?

[ramthis9501]

That aggrevates the crap out of me when that happens

[myoung84]

That could be it. I bought a used tuner and had some problems with it and SC ended replacing it for free under warranty. My trans tuning didn't show up in the software with the new tuner so they had to manually enable it. Ever since then, it doesn't show that I have purchased it in the software, it still has the option to purchase.

Their update software is finicky to say the least, but the tuner and tunes are pretty good.

[myoung84]

And I forget they are in Florida, eastern time zone and close at 5:00.

[(S.M.R) 101]

Ok dude I went into advanced tuning and found all the options like disable MDS rev limiter 1st and 2nd WOT as well as 3 and WOT. and ratios and a schedule option.. is this where I can change the wot shifts and stuff? I'm so lost dude lol.

[(S.M.R) 101]

Right now my WOT shift from 1st to 2nd is at 5800 now I have noticed that every other WOT run there is a clinking noise when it comes from the top of 1st to the bottom of 2nd or soon as it shifts from 1st to 2nd. That can't be good....right?

[myoung84]

Not sure on the clinking noise, that's kinda strange...

MDS disable is a yes or no option, select yes if you don't want MDS. REV limit is just that, setting your rev limit, this has to be at least a few hundred more RPM than your 1-2 and 2-3 shift points. 1-2 shift sets the RPM it will wind to in 1st and 2-3 sets RPM in 2nd.

Then you have your shift schedules and TM settings. You will have shift schedule, OD off shift schedule and 4wd low shift schedule. For now I would just play with the standard shift schedule then once you get the hang of that you can start playing with the OD off and 4wd Low schedules. Keep in mind both of these schedules share same shift points for 1UP and 2DN. Once you are finally able to purchase the trans tuning, there will be an option under each shift schedule and TM page to select "User" then you can modify each gear.

There was a pretty good FAQ on the whole trans tuning I saw a while back, I will see if I can find it.

[(S.M.R) 101]

awesome.. Thank you Morgan.. I have been playing with it and think I am starting to catch on, Been doing a lot of reading

Thanks again dude

[(S.M.R) 101]

Morgan I have my rev limit set to 6000 and my 1st to 2nd set at 5600 and my 2nd to 3rd at 5600 is that enough room between the rev limit and shifts?

Also this thing is set on 31.50 for the tire size arnt the stock tires 33's? Should I set it at 33?

[myoung84]

That should be fine on the Rev limter, just need a few hundred above the shift points. For tire size you will need to measure your tires. The stock tires are actually about 32" under the truck's weight. My Coopers measured 32.25" when new and are now down to 32". I have checked my speed with my GPS and I am dead on with mine set at 32".

[(S.M.R) 101]

yeah I am dead on at 31.50 (Acording to my gps) so i'll leave it..

Thanks bud

[(S.M.R) 101]

Man..... I'm getting a Pause in between the 1-2 WOT, It pauses then kicks into second and that damn clinking noise coming out of the shift but only through 1-2.... this is bugging me...

Still waiting on SC to contact me back..

any of yall's pause before shifts?
