Hello every1,
Basically i own a J reg Xr2i 1.6 8v with a few mods, i bought a genuine"superchips" chip (not 1 of them shitty resister jobs) from ebay, but when i fitted it my car started misfiring and spluttering and all sorts of madness, i tried reseting the ECU by pulling the + lead of the battery and adjustin the fuel pressure up to 2.5 bar but all to no avail, the car smells like its burning a shit load of fuel and hesitates alll through the rev range, i also noticed that when i turn the ignition on the fuel pump does not do a pre-run it just runs as if the car is started, quite strange i think, when i contacted the seller he assured me he had only just unplugged it from the car the morning he posted it and it was all working fine, im baffled to be honest.
If some1 could help id be veryy gratefull.
