Hi folks!

I recently put x30xe management on my Y32SE...
Before that it had c25xe management and i bought week ago original GM Bosch metal crank sensor with square plug,as stated it fits omega 2.5 V6 94' ,all calibras 2.5 V6,vectra B 2.5 v6...everything worked good until i put 3.0 loom and management

Now with x30xe management i have fault 19.I suposse the ECU doesent like the old metal bosch sensor.
It is facelift 3.0 ECU with letter coding AF.
I need help from experienced owners to confirm me that i dont need Siemens type of sensor,if we reffer to this topic...

Thx in advance

Have you simply swapped out the C25 ecu and replaced it with the X30 ecu?

[calibrated]

No,because you cannot start it on c25xe loom...throttle position sensor reads opposite direction on omega(throttle moves in different direction,etc)... i have fully swapped it for x30xe management with facelift loom and facelift ecu,only sensors remained the same(i uncliped spade connectors and properly replaced with few square plugs that i needed)...now i am looking for info which crank sensor i need,siemens or bosch from topic above(link)

[Doctor Gollum]

In which case you need the face-lift 3.0 crank sensor and plug to retrofit to the loom. Along with all the 3.0 sensors.

Possibly easier to start with a fresh 3.0 loom and sensors to avoid missing an earlier bodge.

Newer type of sensor...Bosch...new...put it on the car still same...cut outs randomly under acceleration...only left option is Siemens type of sensor...

If someone can check for me,because i have no software,what throws out as option:

VIN of the car from which ecu is:

W0L0VBF35Y1130989

Year was 2000

Don't bother looking it up on EPC, as GM's EPC is universally incorrect for V6 crank sensors.

All 3.0 and 3.2 taken the more expensive of the 2 options.

Pattern ones, even if (supposedly) genuine Bosch, seem far less reliable we have found repeatedly over the year.

I think ecu is fried,as engine management light flickers with rpm,as you increase rpm it is flickering slower....for me is very hard to obtain something to swap and try because people rarely drive these cars here...i sourced my ecu from germany and loom also,but loom looks so good and perfect to be problematic... i am running out of options... i think i will keep x30xe intake and return c25xe ECU and loom, because car is not driveable at all...the multirams will need to wait little bit while i source known good working ecu

Solved! I got a PS ecu (3liter 94 or early 95) without immobilizer and now car revs and drives ok.I have some another little gimmicks ,but is a discussion for another topic.
