And yes, I still agree that putting a piggyback on top of a reflash is silly if both tunes are coming from different vendors and aren't integrated. FWIW, we've run both a our piggyback and our reflash in many of our higher HP Mitsu Evos. The reflash took care of all the basic injector scaling/latency parameters, rev limits, speed limits, etc,. While the piggyback (which held two toggle-able fuel, boost, and timing offset maps) drove the boost solenoid, provided lean-run protection (in case the methanol jet clogged or fuel pump failed), provided a flat shift feature, etc,. This whole reflash vs. piggyback debate is futile because most people who take one particular side have next to no first-hand hand experience with good examples of the other option. I can recount many reflashes that simply horrible just as well as others can recount many piggyback applications that were equally bad. What matters is not the hardware used but how it is used. The customers owes it to himself to do his homework and find the option that best suits his particular needs. shiv |

There is no "debate" Please tell me what a piggyback can do that a reflash cannot do? You can take this to PM if you'd like. Jim |

To be fair, we did have two boost maps in our Subaru reflash that we were able to toggle back-and-forth (even while driving) by hitting the defoggers switch and WOT switch at the same time. There are cute things that can be done with spare memory and code jumbling. But serious additional features are usually best left to aux. devices, IMHO. Shiv |

Wishful thinking, I know, but I would love to know how a piggy back (ie something on top of the CPU intercepting its’ signal and providing a false one back) could have anything over the CPU (the thing generating the signal in the first place). Only thing I can see is additional outputs on a piggy back which a reflash could emulate with spare output slots currently going unused, correct??? |

We have, in the past, emailed ROM files to Subaru and Evo customers for them to upload using borrowed or purchased flash programming cables. Nice but still not as convenient as it can be. Shiv |
