Jiffy1986 Posted January 17, 2015 Share Posted January 17, 2015 Right, I have a 1994 mk5b 3dr si, which is a 1.6 zetec, running an 'ENVY' ecu. I bought a 'CAST' ecu off ebay from an early mk6, when I plugged it in it wouldn't run, wouldn't even prime the pump with ignition on. I think it's something to do with pats as I think the mk5b is external pats and mk6 is internal, also I thought my mk5b was external edis, so I bought a 105bhp '2FDC' ecu from an xr3i, fitted that earlier and it primes the pump but will not start. Opened the bonnet and there's no edis module that I can see. Also I have an ecu and key from a 2.0 mondeo, I think the code is 'BASH', I could of swore mk5b's had external edis! So in theory the 'CAST' and 'BASH' ecu's should work if I wore the pats transceiver to the ecu???? Anyone know what pins run the pats transceiver on them ecu's? Sorry for the long post but wanted to give as much info as possible! Link to comment Share on other sites More sharing options...

scottybo Posted January 25, 2015 Share Posted January 25, 2015 What engine are you trying to fit to the car? Link to comment Share on other sites More sharing options...
Jiffy1986 Posted January 25, 2015 Author Share Posted January 25, 2015 I have an 1800 130 hp engine, it currently has an early 1.6 zetec in it and I'm fitting the 1.8 in it, but the ecu i have is from an early mk6 so has internal pats, mine has external pats, so need to wire the receiver ring direct to the ecu, but can't seem to find a diagram anywhere for a 60 pin ecu with internal pats!
