Flip chip question
When you flip the switch on a superchip to race does it also clear the computer like unpluging the battery. What i am trying to get at is do i need to unplug the battery after you flip the switch or does it do what unpluging the battery would do by flipping the switch?

Hmm according to an old post by Mike Troyer of Superchips, your flipper can be flipped on the fly but it isn't recommended at WOT or when the engine is under considerable load, especially if the programming on each side is a lot different.
You don't need to disconnect the battery.

Hi LateModelRacer2,
No, flipping the switch on the Flip Chip does not automatically interrupt power, disconnect the battery, or clear the PCM. Nor is that really required, unless you are doing formal testing on a dyno or at the track and are attempting to document exact performance differences between the 2 programs. In which case, yes, you'll want to clear the PCM after each program change to best isolate/identify/quantify.
To clear the PCM, flip the switch on the Flip Chip to the desired program, then remove your keys from the ignition. Disconnect the battery. Leave it like that for a few minutes, then reconnect the battery & then you're ready to drive.
We use a similar procedure, but because the PCM tends to store residual current, after disconnecting the battery we'll put the keys back in the ignition and turn the ignition on for 15-30 seconds to drain the residual stored current to help clear the PCM. After having the ignition on for 15-30 seconds, we'll take the keys back out of the ignition and then reconnect the battery. BE VERY CAREFUL with this procedure, make sure not to *ever* leave the keys in the ignition when reconnecting the battery, or when disconnecting the battery, in these late-model vehicles, as that can cause problems (PATS keys, etc.).
The Flip Chip *CAN* indeed be flipped "on the fly," while the engine is running, we do it all the time. However, it is also true that for years people have heard and seen us advise against doing that (as SVT_KY & others may have seen), and it's primarily just from concern of not wanting people doing that while they're driving on the street. Flip the switch it at a stoplight, or stop sign, etc., with the motor running, we just don't advise doing it while actually driving; not because that can't be done, but just from the standpoint of basic safety (keeping your eyes on the road). This also depends on just what the differences are between the 2 programs as to whether that is appropriate or not. Some require different octane fuels, or are compensating for different mechanical configurations, etc.
Also, remember that when you flip the switch to say, Side 2, where the more aggressive programs are usually stored in most Flip Chips, it will take a few passes at the drag strip before you get your quickest times, as it takes some time & drive cycles for the PCM to pick up on certain program/tuning changes. This applies in reverse also, of course, when going "back" to the program on Side 1, when that is the more conservative program, it will take a couple of passes for the ET's to bottom out.
Good luck!

thnaks mike. I will follow your procedure next time i go racing. I have heard these truck will adjust to daily driving and "soften" up the program. I know my chip will shift firm when it is put in but after a few days it will soften up back to stock.
