  1. well right now im trying to keep the stock fuel cell and usually with a sump setup you need a new cell and that isnt cheap. i do like aeromtive stuff to but it would be nice to be able to almost have something that is plug n play. id like to up the pressure to 70 psi so i coul d get a bit more out of these injectors.

     

     

    I sense a slight redundency here. The rest of you truck is all custom worked over. I think you could fabricate a much more superior fuel system for the same price using other parts. building an aluminum sump tank for our truck should really only cost in the 3-4 hundred range. plus the benifits of the superior fueling is a huge bonus (especially in your case. if you plan on making that engine push 1000 horse with forced induction. I think you should have a fueling system capable of about 1200 horse so their aren't problems with running out of fuel. Just my 2 cents but that other system is put together very nicely.

  2. most emissions dyno's are scrap metal and good for nothing else other than emissions. they don't have the braking capacity to go past 150 horse in most cases. give you an idea, a 2006 Ski Doo MACH Z could max the thing out. not worth more than what a junkyard will give you for the steel in my opinion.

  3. that is a nice set up, but personally i like the aeromotive systems alot better. they should be capable of alot more fuel. also running a sump would be a huge benifit. still gonna be in the 1500 range though. they tend to be alot more consistant. also if you run their electronics, you will eliminate the relays and use solid state electronics which is alot more efficient and trouble free. on of the nicest things is that you can program it to cut voltage at cruise and idle so the fuel dosen't get heated up with a returnless system. :thumbs:

  4. if you take the injectors out, you will see little filter screens in there. you can replace them without replacing the entire injector. standard motor products sells these. check to see if their clogged first though.

  5. maybe this will help

     

    DTC P2A04

     

    CIRCUIT DESCRIPTION

    Heated oxygen sensors (HO2S) are used for fuel control and post catalyst monitoring. Each HO2S compares the oxygen content of the surrounding air with the oxygen content in the exhaust stream. The HO2S must reach operating temperature to provide an accurate voltage signal. Heating elements inside the HO2S minimize the time required for the sensors to reach operating temperature. The powertrain control module (PCM) supplies the HO2S with a reference, or bias, voltage of about 450 mV . When the engine is first started the PCM operates in open loop, ignoring the HO2S voltage signal. Once the HO2S reaches operating temperature and closed loop is achieved, the HO2S generates a voltage within a range of 0-1,000 mV that fluctuates above and below bias voltage. High HO2S voltage indicates a rich exhaust stream; low HO2S voltage indicates a lean exhaust stream.

     

    The HO2S bank 1 sensor 2 and HO2S bank 2 sensor 2 are used for catalyst monitoring. This diagnostic runs once per ignition cycle. This diagnostic consists of two tests, a passive test and an intrusive test. During the passive test, if the HO2S bank 1 sensor 2 or HO2S bank 2 sensor 2 voltage transitions less than 349 mV and greater than 710 mV , the DTC will pass for this ignition cycle. If the DTC does not pass during the passive test, the intrusive test will begin. During the intrusive test, the control module will force the air-to-fuel ratio rich and/or lean. The control module then waits for a predicted response from the HO2S. If the HO2S voltage transitions less than 349 mV or greater than 710 mV , the DTC will pass for this ignition cycle. If the control module does not receive the expected response from the HO2S, DTC P2A01 will set for HO2S bank 1 sensor 2, or DTC P2A04 will set for HO2S bank 2 sensor 2.

    Passive Test

     

     

    The engine is running.

    The above conditions are met for 2 seconds .

    This diagnostic runs one time per drive cycle when the above conditions are met.

    Intrusive Test

     

     

    The engine run time is more than 218 seconds .

    The Ignition 1 Signal parameter is between 10-18 volts .

    The Engine Speed parameter is between 900-5,000 RPM .

    The MAF Sensor parameter is between 5-100 g/s .

    The Vehicle Speed parameter is between 24-131 km/h (15-82 mph) .

    The Short Term FT Bank 1 and Bank 2 parameter is between -4 and +4 percent .

    The maximum number of intrusive attempts is less than 100.

    The above conditions are met for 3 seconds .

    This diagnostic runs one time per drive cycle when the above conditions are met.

    CONDITIONS FOR SETTING THE DTC

     

     

    The PCM detects that the HO2S bank 1 sensor 2 or HO2S bank 2 sensor 2 did not transition less than 349 mV and greater than 710 mV during the passive test.

    One of the following tests fail: Lean Intrusive Test

    The PCM detects that the HO2S bank 1 sensor 2 or HO2S bank 2 sensor 2 is greater than 349 mV for 60 seconds .

    The HO2S bank 1 sensor 1 and HO2S bank 2 sensor 1 is less than 300 mV .

    Rich Intrusive Test

     

     

    The PCM detects that the HO2S bank 1 sensor 2 or HO2S bank 2 sensor 2 is less than 710 mV for 60 seconds .

    The HO2S bank 1 sensor 1 and HO2S bank 2 sensor 1 is greater than 600 mV .

    ACTION TAKEN WHEN THE DTC SETS

     

     

    The control module illuminates the malfunction indicator lamp (MIL) on the second consecutive ignition cycle that the diagnostic runs and fails.

    The control module records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the control module stores this information in the Failure Records. If the diagnostic reports a failure on the second consecutive ignition cycle, the control module records the operating conditions at the time of the failure. The control module writes the operating conditions to the Freeze Frame and updates the Failure Records.

    CONDITIONS FOR CLEARING THE MIL/DTC

     

     

    The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.

    A current DTC, Last Test Failed, clears when the diagnostic runs and passes.

    A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.

    Clear the MIL and the DTC with a scan tool.
