I guess the core program is a Tuned PCM for sale. You do not have to redo it if you switch back to your stock PCM or unplug the battery. Once the CASE relearn is done, it’s done. The CASE relearn will not keep the vehicle from running, however it should be done within at least two weeks of installing the new PCM. Cost will vary depending on where you go – you may want to call around first before deciding between the core program or loaner program. The CASE Relearn can be done by anyone with a Tech 2 scan tool, advanced snap-on scanner, or also a Dashhawk or Aeroforce Scan Gauge depending on the vehicle. So, this would apply to any of our core programs. Anytime you install a new PCM into your vehicle that you intend to run long term, you need to have the CASE relearn done. This relationship helps the vehicle determine advanced misfires. If you cannot get through the security relearn, unplug the battery for about 10 minutes and then try it again, or perhaps have a friend try it for you.Ī CASE relearn is a Crank Angle Sensor Error relearn, which realigns the position between the crankshaft position sensor and the camshaft position sensor. Also make sure you cycle through the relearn for at least four cycles or until the vehicle starts. When in between steps, allow the security light to turn off before trying to start the vehicle. Try not to read too far into it, just do as it says. Security relearn instructions are included with your purchase. ![]() If you install the PCM and your vehicle does start, you do not need to worry about the security relearn. If you install a core PCM and the vehicle does not start, you will need to do a security relearn. ![]() Just had a quick read from the PCM of NC website about Security and CASE relearn Thanks for all the help everyone, although this will have to be filed as a future mod I appreciate all the help and hope this thread may also help someone like me This "tuner" also will do NOTHING for throttle response or shifting or anything else. ^^ this is NOT good!! Trying to force the PCM to richen the mixture by fooling it to think the air temp is much colder! This is s waste of fuel as it will ALWAYS run rich, even when not needing the extra power. DYNO-BOOST tricks the ECU thinking the intake air much more cooler, then the ECU will send more fuel for a richer mix." "simply wires inline with the IAT (Intake Air Temperature) also referred to as MAF (Mass Air Flow), MAP sensor. I'd be more concerned about the claims"Update : I found this programmer : Just take your time and make small changes and do some research to know what to play with and what to leave alone. Tuner software will let you change anything at any time. It does have some preset limits as to what I can do, but I don't have to send out my PCM if I changes gear ratio or tires. The tuner lets me change things over the course of owning it. Not all our trucks have the option to use a hand held tuner. ![]() I bought a hand held tuner, Superchips, for my current 5.3 Envoy. My son is getting his Mustang dyno tuned soon. Of course an mail order tuner can only do so much without having the vehicle there to see or measure the changes. Sent it out, cost me $80 and it made a real improvement in the feel. I had a mail order tune done on a 4.3 Jimmy I had. Other improvements are quicker firmer shifts, adjusting the shift points, redline, max MPH, and lots more. It doesn't add any horsepower, it just makes it available sooner. The factory builds in a slow response to avoid throwing everyone back in their seat when the driver hits the gas, to reduce shock to the drivetrain, to reduce the chance of the tires breaking loose if you jump on the throttle. If you switched to low profile tires with the correct air pressure, and had a quick steering rack, that is what it would feel like, only with the gas pedal. Well, if you had big fat tires on your truck, that were low on air, and had slow steering, that would be what your current throttle response is like, only with the steering wheel, not the gas pedal. ![]()
