Your Unichip works by bending a set of signals to change the outputs from the factory computer. So... as the source signals may have been changed by Ford, your unichip may need a re-tune to get it all tickity boo again. It may also be ok.

I'll hopefully pick it up tomorrow after work.If Ford have upgraded the PCM software, how will it affect the way the Unichip works? If its set back to standard, does that mean that with bigger injectors it will just be using way too much fuel for the lesser ingnition advance? I had planned to get an edit, 968's, exhaust and fuel pump so if it's been set back to standard it may be sooner rather than later. Link to comment Share on other sites More sharing options...
cobrav8 Member 1,969 Member For: 19y 10m 17d Gender: Male Location: New Zealand Posted 23/05/06 10:16 PM Share Posted 23/05/06 10:16 PM Ford have a set of parameters - eg fuel flow rate, and the piggback gets the signal that says eg 10% flow and modifies it before sending to the injector - eg 8% flow (for the bigger injectors).So.. if the new tune was to say 12% flow - and your piggy alters it to be 10% - then yes, you may now be running too rich.It all depends on what has changed on the standard tune from the version you had, to the version they have installed. As Zap said, some cars had problems with one of the recent flashes from Ford.If it wasnt working properly - I would be telling Ford to put the old flash back on. That is assuming you dont mind them knowing you are using the piggyback. That would save you having to get a retune.Your car wont be back to standard. It will be a different standard tune, altered by the piggyback. Link to comment Share on other sites More sharing options...

Runs pretty crappy now. And when I give it sh*t and it either hits a certain boost level or rev range it will run like crap for a couple minutes as well... very gay. Getting it retuned next week (ford wont pay for it because they reckon the car is running well and didnt lose any power). Link to comment Share on other sites More sharing options...
