neonovice Posted January 10, 2013 Share Posted January 10, 2013 I have recently replaced the engine on my P38 2.5 DT. After much jiggering and pokering with the BeCM I got the old girl to start. There were some faults that appeared on the dash to begin with, EAS fault and CAT overheating. I sorted those but now it appears to be in limp home mode. If I rev the engine it will rev to about 4000 rpm to begin with but then it starts bouncing off some kind of limiter at 2000 rpm. I have a Hawkeye pro and have been through the BeCM and ECU but can't see any problems. Any ideas? Quote Link to comment Share on other sites More sharing options...

neonovice Posted January 10, 2013 Author Share Posted January 10, 2013 I just plugged in the Hawkeye and got fault code 10 lost comms with injection timing pump. Does this mean it needs a new injector pump? Quote Link to comment Share on other sites More sharing options...
Escape Posted January 11, 2013 Share Posted January 11, 2013 More likely to be just a wiring problem. Check this first before replacing anything. Quote Link to comment Share on other sites More sharing options...
neonovice Posted January 11, 2013 Author Share Posted January 11, 2013 The donor vehicle was a manual, mine is an auto. Will that make a difference? Quote Link to comment Share on other sites More sharing options...
neonovice Posted January 11, 2013 Author Share Posted January 11, 2013 I have electronically disconnected the gearbox and the engine now revs no problem. Any ideas on how to calibrate the gearbox? Quote Link to comment Share on other sites More sharing options...
Ally V8 Posted January 11, 2013 Share Posted January 11, 2013 The donor vehicle was a manual, mine is an auto. Will that make a difference? Yes,if you are trying to use an engine ecu from a manual car on an auto.If it was just the engine and pump then there should be no problem.

pete3000 Posted January 14, 2013 Share Posted January 14, 2013 I'd say from reading your other thread before the engine swap, you need to copy the settings out of your old becm using your hawykeye pro? or may need to buy nanocom, or use the old becm and resync the new engine edc using bbs syncmate pointed out a while back. essentially the donor engine and becm will start and run as edc codes agree, however the gearbox and body options won't agree leading to some strangeness.

neonovice Posted January 14, 2013 Author Share Posted January 14, 2013 Soooooo.... after far to much work I have bought a syncmate thingmy bob and I'll be changing the ecu and becm back to the original ones today. I'm reasonably confident this will work. Should have listened to you lot to begin with. Quote Link to comment Share on other sites More sharing options...
pete3000 Posted January 14, 2013 Share Posted January 14, 2013 may only need to put the becm back? others may correct me. Quote Link to comment Share on other sites More sharing options...
Ally V8 Posted January 14, 2013 Share Posted January 14, 2013 EDC ecu for manual box will not communicate with autobox ecu,you need to go back to the original EDC ecu and synch that to the BECM. Quote Link to comment Share on other sites More sharing options...
neonovice Posted January 15, 2013 Author Share Posted January 15, 2013 Changed both back, now running. Thankfully just in time for our 'Arctic winter' . Quote Link to comment Share on other sites More sharing options...
