    What does the battery temp. sensor do?

    Thanks, now does anyone know what temp. this happens at? I ask this because I was running at Willow Springs this weekend and it was hot, not just the battery but everything got hot. My battery had a hard time starting the car by the end of the day (it's a one year old Diehard). The battery could...

    What does the battery temp. sensor do?

    Does anyone know exactly how the temp. sensor controls the battery charging? Does it shutdown the charging when it's too high? At what temp. does it do it? I can't find anything in the shop manual about it. TIA Bruce

    Do the math

    ...forgot the distance calc part. Distance is then distance=initial velocity*time + accel* time squared/2. Set the distance at 200ft and assume your starting velocity is zero so the time to 200 ft is the square root of (2 * 200ft/accel)

    Do the math

    A rough estimate would be to find the average torque over the rpm range used and then calculate the acceleration (as if it were constant over that rpm range). Accel=Torque*drive train ratio in first gear*radius of tire/(mass of the car). Your velocity change is then accel*time...or your velocity...

    Help, loss of power

    Kurt, Attach a fuel pressure gauge (you're welcome to borrow mine) to the manifold and route the hose between the hood and cowel. Tape the gauge to the windshield so you can see it while driving. Take it for a spin. If the pressure drops when you floor it then it's most likely the fuel filter or...

    Viper Totaled Today , PICs

    Get the Davis DriveRight carchip (I think that's what it's called). It's about the size of a 9V battery and plugs into your OBD port. It records distance, time, speed, acceleration and deacceleration levels as well as 4 other selectable engine parameters. It also records when the unit is removed...

    Does anyone in here run their radiator fan all the time to help with coolin

    Re: Does anyone in here run their radiator fan all the time to help with co Pullshard, Replace the temp. sensor provided in the kit with one with a lower trigger temp. Stancor makes these and Mouser carries them. They come in a variety of trigger temps. Make sure your replacement unit has the...

    Does anyone in here run their radiator fan all the time to help with coolin

    Re: Does anyone in here run their radiator fan all the time to help with co The other nice feature I like about the Roe controller is that it is wired independent, or parallel, to the Viper fan controller. If, while driving, your thermostat (or the ECU controls, relay, etc.) should fail to run...

    What is it that the stock ECU "learns"?

    What is it that the stock ECU \"learns\"? I have been trying to find some detailed info. on this and have had no luck. How and why does the ECU adapt itself based on your driving? A lot of people recommend that if you want your car to really perform you need to reset the computer and then drive...

    Whats MY COMPRESSION ??

    Here's a question that has been bugging me. Why can't I get my compression ratio by just measuring the cylinder pressure (assuming I have tight rings and valves)? Or can you do this? I have never seen this approach being used. You would have to make a correction for the difference between the...

    Front license plate bracket from Partsrack

    I have one too and think it's a must have. The SD cops are starting to pay attention to the no-front-platers and this is the best solution. The CA vehicle code says that if the DMV only issued you one plate then you don't need a front plate. It used to be that if you ordered a custom plate over...

    HELP! Stalling out question!

    I had the same symptoms but replacing the fuel pump fixed the problem. Start your diagnosis by bypassing the fuel pump relay and driving it. If it still stalls then you know it's something with the fuel pump, fuse or power to it. If it doesn't stall then it's something controlling the relay or...

    EVAP Purge Monitor Failure

    Do you throw a code on a cold startup when your gas tank is low on fuel? Mine has done that. What's happening is that the leak detection pump is not able to pressurize the system within the time frame it's set for and so it assumes you have a leak in the evap. plumbing. Air is compressible and...

    Daily Driver

    The hood has no lock. It just trips the alarm when opened. The gas cap has no lock. There are after market locking caps that work. I do wish someone would make a lock for the hood.

    It didn't fit my 99 either. I noticed the box says 2003-2004. I think they're for the SRT.

    ME412

    About 40 years ago (when I was a kid) I saw my first AC Cobra and I said to myself "someday I am going to own a car like that." Two years ago I fulfilled that dream and got my Viper. Now I have a flashback dream... I want one of those! Just hope it doesn't take another 40 years.

    Problems starting 98 gts

    Yes, check your fuel pressure or at least listen for the pump noise when you turn the key to ON. Then check your pump relay or just replace it (a new one is about $15 and it's good to carry a spare anyway). It should be covered by your warranty. I had a similar problem, turned out the fuel pump...
