i'm pretty much finished installing the Viper 791xv on my car, but my car wont turn over! it'll crank, but it wont fully turn over. i have the remote start and imobillizer module installed, but i dont think the imobillizer would be the cause because it doesnt function unless the remote start is activated. i'm pretty sure all of the heavy gauge wires on the relay satellite are spliced correctly because they are all indicating a 12V current. i checked the battery and it looks fine, but i'll try to charge it anyways to eliminate that as a possible cause. my car has been sitting for about 4 days and it's been pretty cold at night. could that be the cause? i'm probably gonna end up disconnecting all of the heavy gauge wires from the ignition harness and see if my car starts up without them spliced.

 

nvm it was just a cold start.

 

compu star would have probably been the right thing to go with, i have the viper but i'm not happy i had it done by a friend and he knows what he's doing, i can't help you but i can tell you i'm not happy with viper.

 

What exactly are you not happy with?

DEI has the best processing in the market. While Compustart might be a *decent* product, it has nowhere near the reliability of the viper.

I have installed thousands of DEI product and had only 2 failures while Compustart brand is probably 50/50. I have even had better luck with Audiovox.

 

Same here. I don't even bother taking in cars that aren't installing DEI products. It's just not worth the headache, plus DEI Tech support is very good .(But that can be open to debate lol.)

 

ive had both, the 791 and the compustar in both of my evos.... the alarms both operate the same for the most part..... the biggest difference is range. My compustar probably doubles the distance the viper did for remote start and paging functions. The 791 seemed like it was a little easier to use with the car, but the range is the important thing to me.
