VEC2 on a 2002

(Also see post "VEC2 on a 2001" by VIPER GTS) :D

Yesterday I went to my local Dodge dealer to see if my Viper Tech was un-busy enough to install my VEC2 and he was just finishing the installation of the VEC2 on VIPER GTS's beautiful Sappfire Blue and Silver stripes 2001 GTS. He said the installation of the VEC2 was easy and took about 30 minutes just like Sean roe said it would. VIPER GTS's car started right up the first time and sounded ungodly mean at idle. After it warmed up for 3 minutes Bobby, the Viper Tech, took it for a test ride per Sean's instructions. The PCM is disconnected during the installation of the VEC2 and it needs to be driven in order for it to learn how to drive the mighty Viper again. A short while later he came back grinning from ear-to-ear.

Having 2 Vipers at a dealership where normally there are no Vipers drew quite a crowd as my Viper was parked next to VIPER GTS's GTS for Bobby to work on. My Viper started up on the first try, too. Three minutes later I got to sit in the passenger seat of my own Viper for the first time and got taken for a test drive. (I never realized how hard it is to get in and out of the passenger seat compared to the driver's seat before.) The test drive went perfect - no detonation at all. I can see why my passengers say my Viper scares them (HeeHee!).

After dinner I remembered Sean Roe's instructions that after installation of his VEC2 that the Viper needs to be driven in order for the PCM to learn how to drive it again - yeah, like I need to be told that I need to drive my Viper. ;)

I took it out and tried to get in as many driving conditions as possible so the PCM could learn how to drive. It felt like my PCM already knew how to drive in all situations already. I then found a section of interstate with almost no traffic on it and slowed down to 40 MPH, put it in 4th gear, and accellerated slowly up to 50 MPH and then introduced my Snake Pedal to my North California Viper Club Floor Mat fairly rapidly. Oh-My-Gosh! The Roe Supercharger is totally insane and by the time I let off the gas at 95 MPH I had to keep telling myself that I was in 4th gear and not 2nd gear at wide open throttle! The increase in accelleration as the RPMs come up pushed me back harder and harder. I think if I were on a closed course and stayed in 4th gear up to 6,000 RPM (150 MPH) that I would have been trying to convince myself that I was in 4th gear intead of full throttle in 1st gear. :eek:

The Combination of the Sean Roe Supercharger and the Roe VEC2 is even better than sliced bread. If you want a Viper that is much, much easier to drive in everyday driving conditions and can also give you a cardio-vascular workout - my heart rate was higher than normal for 2 hours after my full thottle run in 4th gear - <font color="red">Get the Roe Supercharger and VEC2 ordered right now! </font>

"I have VEC1 and wonder what VEC2 can do that 1 can't?"

The answer is, a lot! Basically the VEC2 has direct control of the timing and injectors and can therefore tune things much more specifically at various rpm levels than can the VEC1 or the MSD boost retard box. It might not matter that much on a stock or mildly modified car, but on a blown application it makes a huge difference (not so much in peak power/torque output but in driveability and getting rid of detonation).

Today I wasn't able to follow Sean Roe's instructions of driving the Viper so the PCM learns how to run the Viper because it snowed all day. Once again, <font color="brown">Where's global warming when I need it? </font>

Sean's instuctions read that you should drive the car in different methods of acceleration for a while prior to really hammering it. Well, Bobby and I drove the car about 30 miles, being sort of good, then the Cobra got on my rear bumper, we figured it was enough break in,4th gear, 5500 rpm, then several back country roads in the 5 to 6 thousand rpm range, both fun and productive, you feel the car running better and better. I could not look down at the speedometer when I shifted into 5th at 5500 rpm but the motor was pulling stong and we were
really flying.. Closed course naturally.
Sean, Thanks, it is great.

It snowed enough last night to cause a 2 hour delay for all the local schools, so instead of A-Vipering I'm A-Going today, it's A-Snow Shoveling I'm A-Going.

I've probably haven't crossed the 4,000 RPM barrier yet since the VEC2, but I've noticed that VIPER GTS has. One thing about his Viper that surprised me 2 days ago when we were getting our VEC2s installed - all his tires had plenty of tread on them - either they are new or Michelin Pilots don't wear out.

Tomorrow I take my Viper in for an oil change - does snow melt much in 20 degree weather?

It looks like it will be a week before my part of Ohio gets above freezing -

Kenny, two things. You don't have to smoke the tires to go fast and remember PartsRack tire sale, I bought six tires in December.

I just got back from A-Vipering I'm A-Going and with driving with much, much exuberance I got 17.3 MPG city/highway/full throttle. With the Roe Supercharger my Viper gets the best gas mileage of any car on my driveway.

jimandela -

You can easily afford a Roe SC VEC2 this year by using all your savings by getting better gas mileage - city/highway/full throttle - to help pay for it.

:usa: It's your Patriotic Duty to help cut our dependence on foreign oil. :usa:
