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_4sogXJKHgÂ

We had the BMW start and went for a street drive. We now have 6 PSI boost, dyno next friday.The Storm works perfect. Â http://www.youtube.com/watch?v=bjrt6ze_bj0

I am realy interested in your base MAP and Vanos control strategy. Can you send me your starting file on my mail : [email protected] Â Thanks, Alex Â

I started to build a new intake manifold for this S62. Â http://imageshack.us/photo/my-images/256/dscn4430m.jpg/'> Uploaded with http://imageshack.us'>ImageShack.us

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.

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.

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. Â Thanks, Alex

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 Â

Nobody for this topic ? I realy want to buy a Link ECU IF I can get a file controling the S62 VANOS.  Thanks, Alex

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
