Question Flash Tuners For Dummies

Hey Lads,


OK, I've asked several dumb questions but this is probably at the top though, I'm a firm believer that the only dumb question is the one you don't ask and we weren't born knowing. My question, WTF are all these VEC, VECI, VECIIIs, tuners, PCMs, flash gizmos and handheld programmers people are speaking of?!?

I'm guessing they plug into the factory computer and you can adjust the factory settings or in better wording override them to gain better performance. Is someone able to break them down into what they mean (VEC = etc) and even better explain in brief which tuners people are using and what that tuner does and is good for?


Thanks,
Carl

VEC = viper engine controller

Here's a link for info on the handheld programer. Alot of people are speaking very highly of this, and I will be getting one shortly.
Hand Held Flash Programmers now available for all SRT Trucks!

More people with more knowledge than I have will chime in

Hey Carl, if your going to buy a Roe you will get the vec with it and tunes from Roe. If your going to stay NA then get a SCT hand held tuner from DC. A flash is a pcm that you change out from your stock pcm. I don't think the flash is worth it on a RC. I raced a RC that had the stage 2 flash and beat him by over a 1/2 sec in the 1/4. My RC is still stock except to shifter and magnaflow. I'm going to buy a SCT when I get the extra $'s. I think its the way to go. This way I don't have to mess the stock pcm.

Aha!! He explained with great relish, of course Viper Engine Controller. Thanks bud, that helps a lot already. It's bloody amazing aint it!?! Hard to believe a small box can "tune" your car. By "tune" what does that mean exactly, tune as in tune and correct any faults or timing issues in the engine, basically a service for the truck or? Again, hard to fathom it can be done, I know this is the technology age but shit, that rocks lol.

Thanks,
Carl

Thanks, yeah, I'm not sure on supercharging mine. Sounds good but I've always had a soft spot for fast N/A engines and driver skill, more of a challenge, like fishing in a boat vs from land off the rocks.

So, if I did buy the SCT (SCT =?), but ended up getting a Roe SC later on down the line, is it just a matter of putting/pulling the SCT out and installing the VEC supplied with the Roe kit? Basically, having a SCT won't hinder having a Roe later on?

Thanks,
Carl

I believe the sct plugs in under the dash. So if you do get a vec later on it should no problem to make the change. You might even be able to still use it, but I'm not sure. Quicksilver has one with his Paxton. Hes the one to ask.

The SCT will not need the VEC. It will do it all through the PCM perfectly Carl.

The VEC is hardwired into your PCM. The SCT is just plug in, make your changes, unplug.
