hey, i'll do it for $100k.. that includes a shiny new 02 GTS right? i'll take yellow please!!
is this motec unit a fully programable ecu for the viper? does it interface with a software program for adjusting fuel curves and timing as well as many other aspects?
or is it a piggy back like the VEC1?

Sorry Eddie but the 100k would only cover the Turbo system and driveline upgrades. I didnt quite phrase that well enough, but I'm sure that I could get Don Sleik from Koller Dodge to get you the Yellow Viper you deserve and throw it all together as one big Monster package.
About the Motec system:
We have built a SVS designed Harness interface that plugs right into the S-bec or j-tec stock computer. The Harness looks just like stock except the possibilities you now have are enormous.
The GTSR program ran their V-10 engines (Caldwell Development) using Motec systems. SVS has used the motec system since 1996 and we have learned quite an extensive amount over the last 6 1/2 years.
Motec tunes the fuel with the IJPU % (injector pulse units percentage)and also controls the timing. These two items are under your COMPLETE control.
You have complete logging of all systems including EGT, (exhaust gas temperature) manifold psi.,gears, lambda 1+2, speed, throttle position.....just to name a few.
You also have the ability for traction control and 60 different types of sensors. At the salt flats We used 2 ride height sensors (1 in front, 1 in back) and linked that information to the Motec digital dash. You dont have to have a digital dash (you can download all your information to a laptop) but at the flats I had to watch and see if the front of the Viper was starting to lift at 240+....It started to.
If you want to know what your Viper is doing from beginning to end at every point of a 1/4 mile drag race.....then you need your car tuned with a motec and place sensors on it.
We can tune sequentially. This means each cylinder is completely managed and gives you the best advantage possible when mapping your engine.
Supercharged packages can be taken to the ultimate in precision with a fuel system and Motec tuning. We would love to help optimize anyones system. We dont want to take anything away from anyones systems, just help make what they have run the best it can. With more power comes understanding and with understanding comes the need to know exactly what it is you have and exactly what it is doing. I like to know thats all.
Im not sure exactly how a VEC-1 works? I have heard that it gives good results for a reasonable amount of $. Yes the Motec is not cheap and you must have a fuel system that matches your overall system. But for the amount of money alot of people spend on high HP, they should at least have an understanding of what and how their system is performing. It is sort of like going to the doctor, read your blood pressure, check your heart rate, (Yeah I know bend over and say AH)Anyway I hope there are some Viper owners out there who see the value in this and realize it is a extremely valuable tool.
Come and talk to us at VOI we will have a booth at the Racetrack.
