Hi guys, Hope you are all safe i am trying to setup my rpm limit and als an launch on my M50b29 Turbo engine is capable of 600-900hp running on normal fuel at the moment with three modes 0.8bar/1.3bar/1.8bar ill go into each issue on its own, if anyone can help me set it up i attached my file (i made the tune from scratch so anyone wanting to copy anything from it i do not suggest that cz u might blow up ur engine) -Rpm Limit: the way it is setup now the rpm limit sounds fast while stationary , but the issue is when im driving and i hit rpm limit i don't know if i reached it cz the rpm holds steady at the limit but the engine sounds normal without any noticable cuts or bangs or anything so its very confusing for me to know when i reach rpm limit how i prefer it is like a small bangs that won't make me lose lots of power and stall and keeps the engine reving up and banging so i can notice it -Antilag : the way it is now when i lift my foot off from a full throttle it will bang maybe once or twice loud bangs and sometimes quiet bangs but in all cases on a gear shift i lose all boost and loose all power and have to wait for the turbo to spool again i don't want anything that sounds good rather i want something that performs well i want to keep at least 0.5 bar after a gear shift -launch: the way it is now once i push the button i rev the engine up to around 4k and i can feel and hear the retard spooling the turbo and hear it wistle but i don't see any boost and when i let go of the clutch and depress the button i have no boost and the engine starts spooling from 0 bar -i want to have at least 0.5bar of boost before i can launch with a little bang perhaps whoever can help out or has a file that works that i can read and try to learn form it or try it is much appreciated Thanks in advance, M50B29 E30M3_V2.pclr

Hi all, just wondering why my ecu’s pin55 is burnt/discoloured. Its melted a bit of plastic surrounding it on head of connector for ecu. I have done some research and on the bmw m50 harness connector, pin 55 is the ignition ground. The link g4+ pin out on my ecu however doesn’t have a function for pin 55. At this point i am wondering if anyone could lead me to the right direction as the car starts up ok and fine, idles fine with the base map Loaded and stored to the ecu. Any help would be appreciated.

Hello everybody, Since I have not finished yet my DIY "detonation listening device" I made a few runs using only the engine knock sensors and very conservative tuning, trying to spot knock signal waves on the logs. To my surprise I found a few spots that look a little suspicious which I would love to hear your opinion about. It's hard to believe that this might be real knock considering the crazy rich AFR and the low timing but still I would bring these to your attention. My engine is a M50TUB25 with about 9.5:1 compression and a smallish turbo. Problem 1: There's a small spike on cyl2 knock level. It settles back and then rises again along with the boost pressure. Might this be knock, or knock should be an even bigger spike compared to the previous average noise? Problem 2: The cylinder 2 noise seems to raise pretty suddenly but the cylinder 6 even more so. I think that cylinder 6 might be caused however by the RPM cut which happens at the exact same time but I am not quite sure which happened first. I also attached the base map and the log file. The first problem is in the SOL section, the second one in the rpm cut section, timestamps should match the attached screenshots. Thank you very much for you help!

Hello everybody,, I have a Link E36 plugin ECU controlling a turbo M50TUB25 E36 BMW. I am almost done with the fuel tables and moving onto ignition tuning so I have some questions regarding the specific configuration of the knock control for this engine. I saw that the help files recommend some frequency settings for certain engines, but no recommendation for the M50 engine. So first question is, could someone tell me what type of knock sensor should be selected, what frequency and eventually the rest of the knock control settings? In case I can't find an answer to the previous question I plan to also listen for engine knock, so I also search for advice on this one. My plan is to build a simple audio frequency preamplifier/amplifier and listen with headphones. The problem is that I would like to keep the ECU connected in parallel to my audio amplifier, so I need to know what should be the input impedance of the amplifier in order to not affect the input to the ECU too much. My guess is that something like 100kohm should be fine, am I correct? This is a question to which I hope I can get an answer from the Link ECU hardware engineers, for which I thank them in advance! Best regards, Florin
