Alexandre KIELWASSER Posted August 4, 2011 Report Share Posted August 4, 2011 Hello I am new on this forum. I am just in the process of selecting an ECU for my BMW M5 S62 engine that will be turbocharged. I wonder if the Link is able to control correctly the VANOS ( 8 positioning  solenoids PWM + 1 pressure solenoid PWM). And does anyone have a base file for this engine. Thanks Alex Quote Link to comment Share on other sites More sharing options...
Alexandre KIELWASSER Posted August 5, 2011 Author Report Share Posted August 5, 2011 Nobody for this topic ? I realy want to buy a Link ECU IF I can get a file controling the S62 VANOS.  Thanks, Alex Quote Link to comment Share on other sites More sharing options...
Fredrik Pettersson Posted August 8, 2011 Report Share Posted August 8, 2011 I wrote a long reply but my internet died and all was lost.Anyway the Extreme only has support for 2 solenoids , i don't know if you can wire the rest as General Purpose PWM's though.Cheers // Fredrik Quote Link to comment Share on other sites More sharing options...
Alexandre KIELWASSER Posted August 11, 2011 Author Report Share Posted August 11, 2011 I am a bit desappointed by the support I can get with Link, I try to have a basic answer for some days now and have no answer from tec support, dealers are also embarassed to answer ! I would really like to try the Link if possible. My next choice will be a Motec that can do everything you can imagine.  Alex  Quote Link to comment Share on other sites More sharing options...
Fredrik Pettersson Posted August 11, 2011 Report Share Posted August 11, 2011 Yeah , they used to answer really quick on here , something must have happened.Motec is a nice choice aswell , abit more expensive though Quote Link to comment Share on other sites More sharing options...
Simon Posted August 12, 2011 Report Share Posted August 12, 2011 Sorry about the slow responses it has been a very hectic time for us. Unfortunately we are not able to do all that you will require on that engine. We could do 2 of the 4 vanos cams and no e throttle. Quote Link to comment Share on other sites More sharing options...
Alexandre KIELWASSER Posted August 16, 2011 Author Report Share Posted August 16, 2011 Thanks for your answer. This engine will have a Precision Turbo 90mm throttle body + GM IAC and TPS. So I only have to find a solution concerning the second vanos. What do you think about controling properly the intake cams for example and sending the signal in open loop mode to the exhaust cams ? Maybe this is a stupid idea as I don't know yet how it is exactly working. The concern is that I now have to build a BMW, but I normaly play with chevy engines. And as your Link is perfect for chevy applications, I would really like to test it as soon as possible, and on this BMW if adaptable.

Josh Burt Posted August 16, 2011 Report Share Posted August 16, 2011 FYI, controlling only 2 of 4 cams isn't a necessarily bad thing. In all of the setups I have seen thus far, when you are not controlling the cams (0% duty cycle to the solenoid) the cams sit at lockpin. Â Now what is the advantage of advancing cams? Exhaust Cam: EGR for better emissions, and there is an argument that you can get a little bit of faster turbo spool but from my experience it is negligable. Intake Cam: Power! Especially midrange. Â In summary controlling only 2 cams isn't necessarily a bad thing. I would leave the exhaust cams alone (no control) and just control the phasing of the intake cams. Or yes you can drop another $5k or so on a Motec and phase your exhaust cams during cruising to be nicer to the environment I personally would not.

Alexandre KIELWASSER Posted August 22, 2011 Author Report Share Posted August 22, 2011 What about controling properly the intake cams as you suggest (I will need some help for this) and controling the exhaust in OFF / ON mode (spare output ) at about 3500 RPM ? Â If this is OK and I can get some support from Link, I will make that with a G4. Quote Link to comment Share on other sites More sharing options...
Gerard Murgadella Casado Posted August 25, 2011 Report Share Posted August 25, 2011 Hello, I have the same question, and I buy Xtreme pro ECU. I think can do follow options: VANOS: the mame output signal go to both valves in same intaque or exhaust cams. 1 output = 2 cams. On e-throttle: the same like a VANOS the same signal go to both e-throttle electric engines. Â I'm not sure if is a good solucion but I need to check. If you have a start up map onli the engine start, can send me and do the same work in both cases. Thanks a lot, Quote Link to comment Share on other sites More sharing options...
Alexandre KIELWASSER Posted August 29, 2011 Author Report Share Posted August 29, 2011 I don't think it is a good solution. If you send the same signal to both cams (one wil run open loop), you may have one cam positioning or fluctuating with absolutely no control. Especialy if you are at steady state driving conditions. I consider limiting the exhaust cam mouvement and switching the solenoïds ON / OFF at a given RPM only.  I will get a factory BMW ignition map from a professional tuner. Keep you informed.

Gerard Murgadella Casado Posted August 29, 2011 Report Share Posted August 29, 2011 I look an other problem with cams. for one cam have 2 selenoids, 1 for advance and 1 for retard. This is more dificult to do the mapping or I need to configure the outpu with other function. I have no the ECU yet but when haved I try.

Alexandre KIELWASSER Posted October 4, 2011 Author Report Share Posted October 4, 2011 I started to build a new intake manifold for this S62.

Alexandre KIELWASSER Posted October 24, 2011 Author Report Share Posted October 24, 2011 I am realy interested in your base MAP and Vanos control strategy. Can you send me your starting file on my mail : [email protected]  Thanks, Alex  Quote Link to comment Share on other sites More sharing options...

Alexandre KIELWASSER Posted July 23, 2012 Author Report Share Posted July 23, 2012 We had the BMW start and went for a street drive. We now have 6 PSI boost, dyno next friday.The Storm works perfect.

Scott Posted July 25, 2012 Report Share Posted July 25, 2012 Hi Alex, Looks like you're making good progress! Let us know how you get on at the dyno. Scott Quote Link to comment Share on other sites More sharing options...
Alexandre KIELWASSER Posted July 31, 2012 Author Report Share Posted July 31, 2012 Everything was fine, we limited the torque to 520 ftlbs. That gives 500 DIN HP. We still have troubles with IAC and ignition timing that not matchs the target map despite no correction mode engaged. Sometimes we cycle the timing at idle between 5 and 25° ...very strange. Looks like there are some little bugs (or we did not found the correct tuning)  in the soft but nothing too anoying. Bosch IAT is also not giving us a correct signal, we had to deactivate it.  Here is the dyno video http://www.youtube.com/watch?v=y_4sogXJKHg Quote Link to comment Share on other sites More sharing options...
