VEC3 Questions

[Tooloe]

Can a stock Motor Benefit from this system? i'm going to have this thing tuned and i want every way possiable to do it.. my motor is mostly stock with some small mods the major one being nitrous... but can some one explain to me how this thing works i'v read up on it and am still scratching my head.......also went to the local performance shop today and they said they couldn't get me the SCT Tuner for my truck yet said it wasn't out I'm calling bull shit.....but anyway if i get the SCT tuner and the VEC3 can they both work together? and what kind of gains can i expect from them?

You want one or the other.

The VEC will be versatile for you.
The SCT will be preloaded with programs you can download and won't have to go to a dyno to tune. Tune is already made for you. Like Superchips or Hypertec programers.

It is your call on which one to get. They will both help. If you plan on doing a bunch of tuning go with the VEC.

The SCT may have additional features in the future however.

There is pro-racer software for the SCT tool, it gives you 100x the tunability of a VEC-3 for about 1.5x the price. The tool does not have to be pre-loaded, you write the programs yourself.

The only reason to use a VEC-3 & SCT together is if you want to add single dimension boost control to the system, or need a PWM/Switched output for something THAT bad. For an NA car, there is just about no reason to use a VEC-3 over an SCT.

ahh ok i'm starting to understand.. i will be getting the supercharger from roe with my income tax but thats not for a few more months..so it looks like the pro version of the SCT tuner will be better for what i'm planing on right now.. the truck will be dyno tuned just for the fact that i want my a/f ratio to be as close to perfect as they can be

 

[Hilgee]

where can a guy buy a vec3??

 

[Dave T(BADVENM)]

Roe makes the VEC3 I think/thought, I'd get it if I were purchasing their supercharger. You can get the VEC through Roeracing.com, they run around $1000.

Currently Roe has not been able to make the SCT work with his SC....this will probably change soon but if you plan on doing the Roe I would get the VEC...in fact if you plan on buying the Roe SC in the next 6 months I would hold off buying any tuner until you buy the SC kit...which will have the most up to date tuning system...my 8.3 cents....

The Vec3 made almost a .5 sec diff on pump gas in the 1/4 for me with a NA 40K mile motor.

 

[Dave T(BADVENM)]

Just adding a vec3 with a custom PBJ tune on my Paxton setup gave me an additonal 40-50 rwhp, nothing else was changed at that point. Granted, you wont get this with a stock setup but you will see some improvements.

Ironically, there are SCT dealers who have successfully set up the Paxton & Roe systems w/the SCT tool & a 2-Bar MAP sensor. I guess Roe needs to catch up!

There isnt any reason to wait on the Tuner purchase. the hardware will not be changing. The software updates are free, and automatic at that. In all honesty, get the software ASAP and start playing with it- the learning curve is HUGE, and flat out overwhelming for a good while. A novice tuner with access to over 1000 tables and scaler values will stare blankly at the screen for weeks, maybe even months before gaining a clue on what to do with most of them.

Correct, Roe is a distributor/importer, but he does not actually make them. the VEC2/VEC3 are USA variants of a product made by Civinco in Sweden. They can actually do much more than we use them for, but the fact that they are running a V-10 limits their capability. they have the ability to be a standalone system on smaller engines if programmed differently. However, their processing power is very small when compared to JTEC controllers, both old and new generation, AEM systems, and it doesnt even hold a candle to the new Fast-CAN controllers and the VENOM controller now used on the Viper.

Sorry, but based on my very satisfied experience with Sean Roe I will have to trust his word when talking about his SC..he said the SCT would not work well with his SC.. .....the Paxton I have no idea..:dontknow:

as far i understood it from contacts wit ROE ( also inquired if SCT was possible ) the difference ( problem ) is they cannot command the meth injection with SCT... VEC3 does ...

He told me the same and something about problems with fuel tables but I cant recall for sure...bottom line was he told me I was just as well off with the VEC even if the SCT would work...He said the main advantage of the SCT would be a cheaper price for his kit..

Personally, and as stated...since your going with the ROE... I would stick with the VECIII... it's proven reliable....and ROE has done all the tuning the SC with it. Why take a chance with something "new".
I also did gain 40 to 50 HP with the VEC prior to the SC.

I would agree. Roe has spent countless hours and has a vast amount of knowledge with the VEC and has numerous tables I'm sure depending on your application. Why go to something new where they dont have quite the knowledge database to optimize its performance.

What each tuner prefers to use is ultimately their business. However, flat out, the SCT is a better way to approach the problem, it is always better to adjust something at the source rather than down the line. Some guys have figured it out, some havent- some even use them together for different uses. Yes, I can understand not wanting to take a risk yet and possibly find out the hard way that someone doesnt know what they are doing. But trust me, sooner or later, the VEC-3 is going to go away, and SCT or SCT-Like programmers are going to replace them. The future is now, it just isnt accepted by many yet.

Just remember, the VEC-3 cannot change how the engine runs in closed loop, and cannot really tune any other parameter effectively except for open loop WOT. It is not a good long-term solution for completely new platforms.

But somehow the VEC....against all the odds...maybe God himself intervenes...but it works....and it works well...

...not trying to be a smart butt GTS...well....:bebored: ...anyway...there are a lot of happy VEC owners here...I know I am...and I bet down the road I will have a different mgmt system on my truck....just dont think the SCT is ready to handle a Roe system...at least not today...

If you are happy with the VEC3, that is great, believe me, I am happy for you, and not in a sarcastic sense. you are one of the lucky ones, BELIEVE ME, it can go either way. I dont know if you really know who I am or what I do, but I have seen dozens, and dozens, and dozens of VEC's over the last few years, and the 100% satisfied rate is about 50%. The other 50%, while not neccesarily 100% dissatisfied, have some issues with quirks in the system. Its not the VEC's fault, its the markets fault as a whole for trying to do certain things with it that it was never intended to do, or anomolies in the PCm itself that it just isnt capable of fixing.

Me convincing you that the SCT is a better solution is a moot point. You have a system that works- there is no reason to change it in your case. Can it be better? I gauran-freaking-tee it, and you would be amazed how many people dont even realize their cars are not running at 100%. But would it be enough of a change to overcome the costs involved? If you are happy as-is, the answer is no. I gaurantee you though, the SCT system can handle a Roe SC, in part or in whole with the right component set. It may need a little help from another system or some intervention under boost as the OEM PCM does not have spare outputs- yet, but that is no issue as the VEC and SCT actually work VERY VERY well together, and there are dozens of simplistic control systems for managing add-ons. If the SCT handles the majority of the tuning, and the VEC is left to single dimension changes, it is flawlessly fantastic and easy to tune by comparison. In effect, the SCT is tuned for the engine, and te VEC is tuned for the power adder. there is no longer overlapping of the two as is with the VEC only. This is obviously WAAAY oversimplified, but I hope you can see what I am trying to say.

We are both beating a dead horse on this one, but believe me, it can do more than you think, and more than some of the big-name tuners think- many havent fiddled with it enough yet, or havent read between the lines. It is a new product, and if you take it at face value, you will be dissappointed. Let me just say, things arent exactly what they seem if you go by the descriptions in the program.

No, I dont know who you are or what you do....and I....well...dang...yes, I agree..it is moot...thanks for your imput...
