Problem with emissions after supercharge installed

[hemimike67]

I was wondering if anyone could help me.  I had a Procharger supercharger put in my 2006 SRT8 back in April.  Now it's time for inspection/emissions.  Garage called and said the machine is saying it's not ready for emissions.  Called the installer of supercharger, and he sent me a program to install onto the Diablo into the car.  I get a message saying "low voltage to program."  Kept going with the install and drove around 150 miles.  Apparently you have to drive it around to reset the computers.  Rechecked it with the tester the garage gave me.  Still not ready.  Went out and bought a new battery.  Redid the install through the Diablo.  Still saying low voltage.  Can anyone tell me what the problem is?  I can't have a car that won't go through emissions.  Half tempted to take back to installer and have it removed and put back to stock!
Thanks in advance

Remove fuse from ecu to clear memory and battery for 1 min and then give it a whirled?

I will try that and let you know if it worked.  Thanks.

contact diablo & they should be able to help.

So we removed the ECU - nothing.  We found someone in the area that is supposed to know the ins and outs of Procharger.  He said it seems like the monitors are not on.  The emission test won't even initiate. We are PA emissions.   So now the garage and the guy who installed are playing phone tag.  We picked up the car tonight and we will be taking the 2 hour drive back to the guy who installed it so hopefully he can see what the problem is.  Does anyone know of anything I can try before I take the trip?

This worked for my srt-10 truck:

For the truck to set the ready status, it has to go through what are called "good trips". They are defined by the PCM being able to complete its system checks on various components. Different conditions have to be met for the system to be able to complete each of the verifications. You might try a couple of things and see if it works. These will set the conditions for some of the tests.

1. Start the vehicle and let it sit and idle for 2 minutes. Cycle the key off and then on.
2. Start the vehicle and with the vehicle in park/neutral, hold the throttle so that the engine speed maintains 2000 rpms for 30 seconds. Return to idle and then cycle the key off and then on.

If that doesn't work, you can have it inspected at the dealership (should be same price). They are pretty good at forcing it to perform the self-checks and getting the system to say that it's ready.
OBD-II Driving Cycle
If you have a 96 or newer vehicle you have the OBD-II diagnostic system. This system is constantly monitoring the sensors and solenoids on the engine. If you have replaced the battery, disconnected the battery or cleared the codes after making a repair you will need to do what is called a "Driving Cycle". This will perform a diagnostic on all the systems the computer monitors. This cycle can be done in under fifteen minutes.

To perform an OBDII Driving cycle do the following:

1. Cold Start
In order to be classified as a cold start the engine coolant temperature must be below 50ºC (122ºF) and within 6ºC (11ºF) of the ambient air temperature at startup. Do not leave the key on prior to the cold start or the heated oxygen sensor diagnostic may not run.

2. Idle
The engine must be run for two and a half minutes with the air conditioner on maximum and rear defroster on. The more electrical load you can apply the better. This will test the O2 heater, Passive Air, Purge "No Flow", Misfire and if closed loop is achieved, Fuel Trim.

3. Accelerate
Turn off the air conditioner and all the other loads and apply half throttle until 88km/hr (55mph) is reached. During this time the Misfire, Fuel Trim, and Purge Flow diagnostics will be performed.

4. Hold Steady Speed
Hold a steady speed of 88km/hr (55mph) for 3 minutes. During this time the O2 response, air Intrusive, EGR, Purge, Misfire, and Fuel Trim diagnostics will be performed.

5. Decelerate
Let off the accelerator pedal. Do not shift, touch the brake or clutch. It is important to let the vehicle coast along gradually slowing down to 32km/hr (20 mph). During this time the EGR, Purge and Fuel Trim diagnostics will be performed.

6. Accelerate
Accelerate at 3/4 throttle until 88-96 km/hr (55-60mph). This will perform the same diagnostics as in step 3.

7. Hold Steady Speed
Hold a steady speed of 88km/hr (55mph) for five minutes. During this time, in addition to the diagnostics performed in step 4, the catalyst monitor diagnostics will be performed. If the catalyst is marginal or the battery has been disconnected, it may take 5 complete driving cycles to determine the state of the catalyst.

8. Decelerate
This will perform the same diagnostics as in step 5. Again, don't press the clutch or brakes or shift gears.
