Greenday694 Posted January 1, 2019 Report Share Posted January 1, 2019 I probably should have started with this question first. I didn't because I thought I was going to be able to get it tuned on a dyno. But I can't find anybody within a hundred-mile radius that will work on a modified BMW with an Eaton supercharger. I've been trying to get the timing set right. Using the PC link software on my laptop and a good set of noise cancelling headphones. Unfortunately I don't hear anything. I'm not sure if I even have it set to the right frequency. Right now it's set at 6 kilohertz narrow band. Gain channel 9, Windows start 5, window length 50, ignition retard limit 6.0, retard gain .5 degrees, Advanced delay 1 second, Advance rate .5 degrees per second, RPM low lockout 1300, high RPM lockout 6200, throttle position low lockout 40% throttle position Delta lockout 10%. Can anybody confirm if this is correct? M 50 BTU 25 engine, M54 B30 bottom end. Eaton m122 H supercharger. Deka 60lb injectors.

Adamw Posted January 1, 2019 Report Share Posted January 1, 2019 What are the headphones connected to? Some type of knock detection device? Quote Link to comment Share on other sites More sharing options...

Adamw Posted January 1, 2019 Report Share Posted January 1, 2019 You will need some type of knock detection device to listen to a knock sensor. We make a device called the knockblock or there are other 3rd party options around. http://dealers.linkecu.com/G4PlusKnockBlock Quote Link to comment Share on other sites More sharing options...
Rob W Posted January 1, 2019 Report Share Posted January 1, 2019 Dive hose, Brass T and a short length of copper pipe on the engine block. Cut two pieces of hose about a foot long and make two neat holes in a set of ear defenders, put a length in each hole and use the brass T to join them to a piece of hose long enough to get to the engine. Put the end of the hose in the copper pipe and you will hear everything that engine is doing. Quote Link to comment Share on other sites More sharing options...
