    Stinking check engine light!

    The ground wire ends up at a ring terminal at the A/C compressor, that is, the wire should be terminated by one of the A/C compressor bolts.

    Emergency brake POPS and has a spring sound when pulled up high ... normal? ---

    The grease on the ratchet mechanism can dry up, I lubricate them with ZEP45 which is like TriFlow, you might want to try that.

    PCM reset and now have power / Need Help

    Don't mean to reply to such an old thread lol , but the likely cause of your loss of power is the long term knock trims. Just like with the fuel trims, there are adaptive values for spark retard from knock. When you disconnect the battery, the volatile memory is cleared, which is where adaptive...

    SCT Question.

    I don't believe it's so much that they are behind , it's just that there is not nearly the same market for Dodge tuning software. Also, GM and Chrysler go about things differently , GM uses a VE model taking advantage of both MAF and MAP , while Chrysler (up until the 08-> VENOM) has used a MAP...

    Stabilizing Cooling Temps With A/C Fan???

    I agree with dave6666 , the only way to effectively cool down then engine is to get more air flow through the radiator. We have a kit that adds two additional cooling fans in front of the A/C condenser to push the air through, in effect boosting the stock cooling fans capability. It makes a...

    SCT help

    I'm not quite sure I understand what you are saying here. If the issue is that you cannot save in Advantage , then you should contact SCT. It would help if you could provide a more detailed, step by step of what you are doing when you try to save and program you car. - Chris DC Performance...

    Ideas on possible fuel system upgrade

    We have worked on, repaired, and rebuilt many fuel systems at our shop. I would say that sumping, or running a pump pickup to the bottom of the fuel tank with no surge tank or fuel reserve is a unacceptable. Let me clarify one thing about the factory fuel pump, it has two separate functions in...

    Engine management

    We have done SBEC calibration work on supercharged cars, but have not been able to tune them without help from a piggy back controller. The fueling strategy is very different from the straight pulse width look up tables that the JTECs use . It's a ongoing project, but I hope to have a working...

    Gen 1 - Idling Question

    Besides the advice from the previous post, is the engine modified, and is this a new problem that just started happening? I think it is likely unrelated to the fuel pump replacement, other than if you disconnected the battery, it may have wiped any non-volatile memory where adaptives for AIS and...

    Tuning Gen 1 PCM's

    Gains can depends on what kind of modifications have been done to your car. With minor modifications, you may not see huge improvements. We have found there is a bell curve relative to certain bolt on modifications and the calibration. The early SBEC cars can run on the rich side stock...

    DC Performance doesn't just do Vipers

    If I remember correctly, Claude Short closed on the last day of 1999, Simonson Mercedes bought the Dodge franchise we had a satellite shop until sometime in 2001. Dan opened DC Performance somewhere around the beginning of 2003. - Chris

    Scan Tools for the Gen3 that monitor spark/knock??

    Good data logging tools that support the pre NGC J2190 SCI ecus are, from what I have found, non-existent. There are several tool manufactures that use the SCI protocol, and can access the PIDs you need, the problem is, the update rate is so slow, that the data they provide is almost useless...

    Engine management

    Useful data logging is a big problem for people who are either trying to tune their cars themselves with the SCT Pro-Racer package, or are trying to relay useful information back to the person who is modifying their calibration. The Palmer XL suite, or similar setup such Logworks with the obd2...

    Engine management

    I prefer to use the stock ecu for customers that value reliability, and no fuss drivability, over ease of mapping and the advanced data logging capabilities you get with most stand alone systems. Although some people have had zero failures or trouble with their AEM ecu, others have not been so...

    2000 GTS with RSI 510 motor. Bucking??

    If it can be tuned out via calibration work, then I should be able to do it through the stock ecu. In other words , as long as it's a solid build, then we should be ok to tune it.

    2000 GTS with RSI 510 motor. Bucking??

    Hi, this is Chris from DC Performance, I'm responsible for the calibration work here, and thought I would chime in. Cammed Vipers tend to buck in the lower rev range to varing degrees, with the amount of bucking depending on the parts combination, compression ratio, O2 senor location, header...

    wiring diagram for connectors used for speedometer calibrator

    As Dan said, I don't think that a speedometer re-calibrator will work, as the wheel speed is calculated at the ABS controller then bussed to the cluster, there is no digital signal to change. The ABS module do simulate a speed sensor signal that goes to the JTEC engine controller, but that is...

    Paxton Help - Again

    Hi, this is Chris from DC Performance, do you still have a boost issue, if so, are you saying that it won't reach peak boost at high rpm and full throttle ? If you have a serial port on your computer, it may be very useful to log the boost through the SplitSec timing controller. - Chris

    O2 sensors moved to merge collector, preheat codes back

    The 2000 model year Viper does seem to have a very sensitve O2 heater OBD2 monitor. The "Quick Fire" O2 sensors do correct this problem in many cases, however, the OBD2 monitor can be altered to prevent the O2 heater code from setting as well. We have done this for some problem vehicles. -...

    Codes, tuning with Stryker Heads and Cam?

    Tim, the SCT device is a flash tool, that allows someone to upload ecu files (in SCT format) into the device, from a laptop or pc. You can then flash this calibration into the vehicle. The first time you connect the device, it will read and store your original ecu program in you car before you...

    Codes, tuning with Stryker Heads and Cam?

    As long as the parts combination is close to a tune we have already done, which sounds like it is, the car should run well. As you probably already know, when you are doing heavy modifications to any car, there is always the chance that problems can come up. Hopefully you don't have any, but...

    Codes, tuning with Stryker Heads and Cam?

    The Striker head/cam combination is awsome, although it does present some tuning challenges. You could tune the wot afr and timing with the VEC2/3 or other piggyback device, but you will still have drivability issues if you don't recalibrate the pcm. Because of the overlap of that camshaft and...
