Tommy Luhr Posted November 19, 2012 Report Share Posted November 19, 2012 I got one big problem. My Link storm dosenÂ´t catch my engine when it comes back from high revs. On idle, the solenoid works and the idle is stable. I have tested different pwm settings from 30-100hz and 200hz and it works best with 50-100hz. The solenoidÂ is a bosch Â 0280 140 545. 3 cable and it came from a bmw m50b25 -93 The engine got a little bit lowerd compression and have a mild ported head.In this shape with all this components the oem ecu have no problems to work with this things, converted to link and now it is a big problem. The biggest problem i can see for the moment are that Link dosenÂ´t adjust theÂ duty cycleÂ fast enough. If i could make a 3d table with rpm and temp axis i could set the base position duty manuel and perhaps that will catch the engine from stall. When i look at the realtime values link is to slow with anti stall kompensation and the engine has already droped 500rpm below target. I want it to catch the engine before it reach idle rpm. I have tried everything and the only thing that worked a little better is the early idle solenoid from m50b25 1991-92 (bosch with 524 last numbers) That is a little bit different but works on the same way with one master and slave channel (aux 1 and aux2) The problem is bigger if the engine speed drops fast but it can also suddenly be a problem when cruising in town and press clutch and brake att the same time. The engine stalls. I got idle ignition activated, that helped. Afr is stable and i drive tps at main fueltable and a 4D fueltable with map compesation so the engine is most of the time at lambda 1.0. If the engine drops below idle target it gets more fuel and ignition just like the oem ecu are programmed to do (thats what i heard). Is there any way to get this 3d table for base position dutycycle (idle) ? Is there any way to get rpm/sek compensation so if the engine drops faster there is more gain to theÂ duty signal? i Thought this things will help me sort the problems out. The car is a bmw e36 1993 build for turbo but runs N/A right now for serious tuning before turbo installation.It runs on E85 and it works kind of okay so far, starts well in -5 celsius (23 farenheit). Siemens 630 injectors, multi point group abd VAG coil on plugs waste fire. Ps i tried the settings that came with your plugin box for this engine- no sucsess. Is there other drivers for the idle solenoid in the plugin ecu? Can that be the problem? Regards Tommy Quote Link to comment Share on other sites More sharing options...
