3. Another common use for these analog inputs are for MAP sensors The GM 3 bar MAP is a common sensor used to measure high levels of boost The conversion for this sensor would be V 9 14 8 or a slope of 9 intercept of 14 8 The intercept can be tweaked if the sensor does not read 0 with the key on engine off Our personal 3 bar MAP had a slight zero offset that we adjusted by changing the intercept value These inputs use a 10 bit A D device and are highly accurate to 01 volts You will only see a resolution of 0 1 volt displayed but the calculations are based on the full 10 bit conversion and are not rounded off for higher accuracy q Analog 2 Same as Analog 1 Uses the left pin of the three pin connector OBD2 powered versions only If the gauge is not returned to scan mode after 10 minutes the menu will time out and return to normal scan mode on its own If the vehicle is shut off while the menu is displayed the unit will stay on for the remaining 10 minutes before timing out returning to scan and then turning itself off Powering down The Interceptor will automatically shut itself off within seconds of the ignition being turned off OBD2 powered dual SRT 4 units may not power down at the exact same time Both single and dual gauges may also momentarily turn on when the vehicle is locked or unlocked Non Volatile Memory The Interceptor does not require batteries or a continuous power source to maintain its memory Thi
4. in our test vehicle an 03 Mustang Cobra there was a 0 01v difference between the chassis ground which we used for a 3 bar MAP sensor and the signal ground on the OBD2 port which our Interceptor was connected to This resulted in an offset of 0 6 psi after the conversion was entered We saw this with the ignition on engine off where we should have seen 0 0 psi but instead saw 0 6 psi To correct this we adjusted the intercept value of the analog input by 0 6 to eliminate this error We have not seen this grounding issue on many cars but if you see it on yours this is how to correct for it 17

Chrysler DTC s at http www aeroforcetech com files SRT 4_DTC_s rtf Dual Units Each gauge will have a separate part number in the form of PTxxxxx6 or PTxxxxx8 The ones that end in 6 will be fully functional the other will not have the performance timer function or the shift light This was necessary to eliminate the possibility of overloading the data bus with too much traffic SRT 4 Dual Units Each gauge will have a separate part number in the form of SRx0x106 and SRx0x108 The ones that end in 6 will be fully functional the other will not have the performance timer function or the shift light The SRT 4 version ending in 8 will not log at 10 samples per second as the 6 will but rather at 2 3 times per second Both of these steps were necessary due to limitations of the SRT 4 bus It simply cannot handle the high rate of acquisition that two gauges running full speed produce If you run either gauge at the 1 data rate fastest the other should not be run lower faster than 3 Both can be set to 2 or higher slower Knowing this set the 6 gauge for parameters that require monitoring at a high data rate such as knock retard or ignition advance This way you will catch any transient or quickly changing values Slower changing parameters such as intake air temp or engine coolant temp can be logged on the 8 gauge at 2 3 times per second without missing anything important SRT 4 PT Cruiser P

RO version gauges Besides a having a number of additional parameters compared to the standard unit there is no altitude correction menu option it is not needed as the barometric pressure parameter takes care of this automatically Also you will find two additional menu options titled Fuel Economy and Fuel Economy Reset Fuel Economy when chosen will display the average mpg since the last time this parameter was reset and miles to empty MPG Reset resets these parameters and starts the calculations over again These two parameters are calculated not continuously updated you must re select this menu item each time you want an updated value Also note that average mpg and miles to empty are ONLY calculated while instantaneous mpg is displayed in scan mode If instantaneous mpg is not displayed the average is not updated This is necessary to maintain the scan rate of the unit Too many calculations done 16 in the backround will slow the process down and adversely effect the scan rate which is extremely important SRT 4 PT Cruiser vehicles using MAP clamps The clamp will effect the horsepower reading skewing it low The MAP sensor output is used in the equation and clamping it will result in an inaccurate value Analog inputs On some vehicles signal ground and chassis ground are at different potentials Depending on how the source of the analog signal is grounded a voltage offset can result For example

16. highly recommended as most of the problems with the gauge can be traced to a poor selection of a 12v wire or poor connection If the gauge randomly turns off and on while driving 90 of the time it is a poor connection to 12v or an improper circuit was tapped into such as a signal wire to the instrument panel This power wire is not needed on all vehicles if your cable has this separate red wire in the center of the 3 wire mini connector it needs to be connected as described above Most GM vehicles made through 2006 require this connection OBD2 connector i me 4 Figure 2 6 Connect the 0 5v analog inputs optional You will see 3 pins above the main connector on the back of the gauge as shown in figure 1 The 2 outer pins connect to the analog inputs The center pin is for switched 12v power as described above and may not be required The right side pin when looking at the rear of the gauge goes to analog input 1 The left pin is for analog input 2 See figure 1 Included in the gauge packaging is a 3 wire cable that connects here This connector is not keyed so it will attach either way Once attached to the gauge make note of which wire is for analog 1 and 2 You ll need to remember this if and when you connect a signal to these wires These inputs can be used to read the outputs from pressure senders A F ratio analog outputs 2 or 3 bar MAP sensors or any voltage up to 5v that you want to monitor and or record You
