Ecu T4

T4spanish · Sep 18th, 2019, 20:42

Hello everyone, I have a doubt. Is the ecu of the Volvo S40 T4 from the year 2000 onwards compatible with my Volvo S40 T4 from the year 98?

NO , the later ones have variable cam timing that is just one of a few differences .. ...

and with a tuning could not be adapted? I currently own 284 HP, but the ecu is failing me and I'm looking for one to replace it and re-tune it

does anyone know the reference of the ecu of 98?

PH1 T4 has Siemens EMS2000 ECU. As far as I know, it is quite difficult to tune. I have been told that EPROM cannot be programed in the ECU, but should be taken out (de-soldered?) and programed separately in EPROM programator. I know it can be done, but obviously people who know how to do it are not willing to share :-(

and the 1999 and 2000 model is also Siemens ems2000? if it is apparently the same on the outside, how can you tell the difference? Thank you

Yes it is on the B4194T2

and the b4194t2 is not the same?

B4194T and B4194T2 have different pinout as they use different sensors.
