hsa101 Posted September 25, 2016 Report Share Posted September 25, 2016 We have a 1992 bmw 525i (m50 non vanos motor) in the shop that we have built. We had the car running on the factory ecu before we began installing this one. We are using an e36 plug/play ecu to run our non vanos motor. All the pins have been moved around to the correct spot.Trigger 1 vr crankshaftTrigger 2 VR camshaft (we used the original m50nv camshaft sensor, it is a vr, the e36 is a hall effect)All 6 injectors tested okAll 6 coils tested okCoolant temp okIAT sensor okCranking RPM is 200 rpm in the link ecuTrigger 1 and Trigger 2 show NO errorI have tried using 84, 276, -84, -276 as a trigger offset for trying to get this to fire up.I have had someback fires and "almost" starts.Need help on what settings to use for the trigger.Thanks. Please keep in mind this is obdI e34 m50 non vanos motor. The crankshaft pulley that is on the motor, is still an original one. Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 25, 2016 Report Share Posted September 25, 2016 Have you put a timing light on it and done the trigger cal? Quote Link to comment Share on other sites More sharing options...
Nettlez Posted September 26, 2016 Report Share Posted September 26, 2016 You will need to wire some igniters in, standard Ecu has them built in, your effectively getting a weak spark. Your ignition timing should be -84 degrees providing your crank sensor wiring polarity is correct, if it's not then it will run on 276 but you will end up with trigger and rpm errors. Will put some links up to the igniters and plugs I used Quote Link to comment Share on other sites More sharing options...
Nettlez Posted September 26, 2016 Report Share Posted September 26, 2016 Hi, as per the message I sent youI'm afraid if you are using the m50 coils you will definitely need external ignitors. I went through all this my self a few months ago. If you look on the link below at the bottom it lists the ignitors as an extra, doesn't say there built in.http://dealers.linkecu.com/E36Plus You will need two of thesehttp://www.ebay.co.uk/itm/390972683826?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AITand again two of thesehttp://www.ebay.co.uk/itm/111088132647?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AITand to wire them like thishttp://www.bosch-motorsport.com/media/catalog_resources/Ignition_Module_IM_32_Datasheet_51_en_2778309387pdf.pdfIt would be a good idea to post a scope of your tirggers and what map you are using too. And as Adanw says ignition timing will need to be checked with a timing light, I brought this one and it worked a treathttp://www.ebay.co.uk/itm/110711496588?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AITHope this helps Quote Link to comment Share on other sites More sharing options...
Nettlez Posted September 26, 2016 Report Share Posted September 26, 2016 He's got it running now with -84. His Ecu had the igniters built it FYI Quote Link to comment Share on other sites More sharing options...

Nettlez Posted October 9, 2016 Report Share Posted October 9, 2016 Trigger two polarity looks to be wrong, try swapping the wires Also is this a non vanos engine? Scott 1 Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 9, 2016 Report Share Posted October 9, 2016 Definitely trigger two wired back to front. Quote Link to comment Share on other sites More sharing options...

Nettlez Posted October 17, 2016 Report Share Posted October 17, 2016 are you using the vanos crank wheel then? Your cam pulse doesn't line up with you missing tooth gap on the crank wheel like mine does, thinking you might have the wrong crank wheel on? Have you zeroed in your ignition timing using a timing light? Quote Link to comment Share on other sites More sharing options...
Steve Posted October 17, 2016 Report Share Posted October 17, 2016 They shouldnt really happen at the same time. Might confuse the ecu Quote Link to comment Share on other sites More sharing options...
golf-2 Posted October 24, 2016 Report Share Posted October 24, 2016 i use vanos bottom end with the stock vanos crank wheel, yes i notice there r gap with the nv cam synci swapped the cam wires, it read well, i use -325 calibrate, but i have feeling the car advances more than the tablei have timing light but i don't know where is the timing mark in the m50s enginesthanx for support Quote Link to comment Share on other sites More sharing options...
Nettlez Posted October 24, 2016 Report Share Posted October 24, 2016 Timing marks can be found here http://www.msextra.com/forums/viewtopic.php?f=101&t=34345 i lined it up then made marks on the sump and wheel so you can check it with a timing light Quote Link to comment Share on other sites More sharing options...
Hussain-vtec Posted November 6, 2016 Report Share Posted November 6, 2016 swap you pulley put m5o vainos crankshaft pulley & swap your engine harness wiring m50 vainos as well. Quote Link to comment Share on other sites More sharing options...
