Sup everyone was just loking at this item i found on ebay and was wondering whether it would work and effect the performance of my car.

http://cgi.ebay.co.uk/Fiat-Grande-Punto-1-4-ECU-Piggyback-Remap-Tuning-Device_W0QQitemZ120288166290QQcmdZViewItem?hash=item120288166290&_trksid=p3286.m14.l1318

Thanks

Description looks very much like a resistor to change the maf sensor reading for the ecu to make it think it's colder than it really is to increase fuelling.

These are not a bad thing when done correctly and with proper research into the resistance needed to do it safely. Doubt the Ebay seller has done this though and it will be the same resistance for every "piggyback Chip" he supplies.

In short. Don't do it. Bore wash isn't funny.

Ok so its a bad idea unless you know completely what your doing.

Ok thanks m8
