  1. Assuming that the original engine was an M50, the information I have shows pin 44 as the ground for engine intake air temperature, engine coolant temperature sensor and throttle position sensor. The ground wire for those sensors should run to that pin.
  2. Thanks Adam. No vanos to worry about fortunately. This is not the engine that will be getting the Link so hopefully that one will be better.
  3. Having sorted the M42 and the M44 bottom end with an M42 head, the time has come to set up a "pure" M44. The M44 differs from the M42 in that the M42 has a single pole cam trigger with the reluctance cam sensor on the exhaust cam where the M44 has a Hall sensor on the inlet cam providing 4 pulses of different durations across the cam rotation (2 crank rotations). Crank trigger is 60-2. Attached images show the cam pulses against the 2 crank rotations. Current plan is to install a G4+ Atom. Is there any benefit in trying to utilise all the cam pulses or alternatively does the Link provide the ability to mask the unnecessary pulses, retaining one as the primary trigger. Thanks.
  4. Furai, if you still have my number give me a call. I may be able to help.
  5. Finally got the car back to the track for testing. With suggestions above the spikes were still present. Made 3 more changes. First was a 1mm spacer under the cam sensor (on the suggestion of our tuner) Second was restore Trigger 2 to reluctor and the third was to disconnect an earth wire between the coil harness and the main common earth point on the engine. The coil harness included an earth to one of the coil mounting screws via what looks like a choke. On the original harness the earth was also duplicated to the block so I left it in the new harness. The engine now revs freely to the 7k rev limit without any sign of any spikes on the engine speed trace. What made this so confusing is that we have 2 cars with almost identical setups and only one was exhibiting the problem. Thanks for your help.

    I had the same problem. Seems to happen if you try to use your email address instead of your User Name.
  7. Unfortunately the cam sensor is a reluctor as well. Doesn't give me those options.
  8. 1. Ignition is sequential. Storm feeds Bosch 4 channel igniter which drives 4 Bremi 11 860 coil on plug coils. We have this almost identical setup on 2 cars but the other one has not been giving this problem. The only difference is that the other is an M42 which has a different crank sensor which is mounted on the front of the engine sensing off the front pulley (still 60-2). 2. 5000RPM trigger scope attached. 3. Will try that before we get back to the track. Unfortunately nothing planned for a couple of weeks.
  9. Triggerscope traces (at idle) attached. 19000rpm was only a little spike, there were several to 65K. Thanks Trigger Scope Log 2018-02-22 4;38;11 pm.llg
  10. We are runnning a G4+ Storm on a BMW M44 and seem to be getting random spikes on the crank sensor that are triggering the rev limiter. See attached log file. There is not a lot in the log but I think enough to see what I mean. The M44 uses a 60-2 toothed wheel mounted inside the crank-case, just ahead of number 5 main bearing. The crank sensor is mounted to through a hole in the block just below the starter motor. We tried another second hand sensor but that made no difference and have now replaced the sensor with a new one and rewired from the connector on the sensor directly to the ECU using new screened cable, bypassing an intermediate connector at the firewall. The spikes only seem to occur after a few laps racing which seems to indicate that temperature may be an issue however the ECT is not going over 90°C. After looking at a few similar cases in the Forum I am wondering about increasing the "Limit Ctrl Range" for the RPM limit to see if that helps. Is there likely to be a downside to doing this? simon log 04022018 race 2.llg
  11. Currently installing a G4+ Storm on a BMW M44. The M44 has 2 knock sensors as standard. Am I correct in connecting these to pins 22 and 23 and configure AN Volt 2 as a second knock sensor.
  12. Hi Simon. Thanks for the info. I have found the new W7 drivers from Silabs website (it uses a CP2101) and installed them. Firstly I tried in the default folder as specified in the install program however that didn't work, then I tried installing it in the c:\program files\Link\Comlink folder which is the default for the Comlink drivers and still it wouldn't work. When I open the drivers window for ComLink in Device Manager it still says no drivers are installed and cannot see a suitable driver in either the Silabs folder or the ComLink one. I can keep using my old XP laptop in the meantime but would quite like to migrate if I can. Cheers Euen
  13. I have been trying to set up PCLink 2.5 on a W7 laptop however I cannot get the ComLink drivers to instal correctly. My ecu is a LEM V5 which I have been able to connect to over USB to using my old XP laptop however the ComLink drivers do not seem to be installing correctly in W7. When the ComLink box is connected to the W7 laptop, Device Manager can see it however it is listed under "Other Devices" not under a USB port. When I run the ComLink Preinstaller, it copies across the files to c:\program files\link\comlink but they do not seem to install properly. When I check the driver info in Device Manager it says that there are no drivers installed for the device (Code 28). (see picture) On the XP laptop, viewing the drivers shows a couple of files in the c:\windows\system32\ and c:\windows\system32\drivers folder so I tried copying them across there as well but it still wouldn't work. I have also tried all 8 Com port options in PCLink. Any ideas?? Regards Euen
