Anyone know how a 95 t-bird with a Mark motor and tranny drives on a stock programed t-bird ECU? Just trying to figure out what to look for before the flash.

Havn't got the RPM switch on yet. Was just curious on how the tranny would act without the tune. Yeah I don't plan on driving it anymore until the tune.

well the transmission will shift at whatever speed and/or RPM your stock EEC tells it to...that wont be a problem....what would be a problem is that your fuel and spark will be all messed up due to the completely different heads and their burn characteristics along with a completely different intake manifold......both of which are taken into account when calibration is done at the OEM level........there are tons of things that add-up and work together within the EEC to make cars idle and drive as smooth as they do when they are stock

and a different MAF, injectors.....

It's an easy way to go into detonation and break a ring land.
