Summary of change:
'''BMW E36 328T''' * Engine: '''6 cylinder, 24V, inline-6''' * JE pistons CR 8.0 * Eagle rods * 1600cc injectors (30V flyback) * Holset HX50 turbocharger * E85 power :) * VEMS v3.3 without CAMSync ---- '''2008-07-28''' '''Problem with low map VE bins''' I have problem with low VE map bins. There are strange values needed (higher at 30kpa than at 50kpa) and the engine is runing rich, but if I try to lower them it will start detonate and wideband shows extreamly lean. Maybe this is normal with Ethanol? If I slowly rev the engine @ ~30kpa, lambda shows 1.02, bet when I stop reving and hold stable rpms (e.g. 5000rpm) it starts to run rich and lambda goes to 0.72... I have almost perfect idle at 900rpm. Also my warmup table looks strange as it likes less fuel at warmup. Could it be mehanical isue like too retarded exhaust camshaft or pulsations in fuel rail? I will bee thankfull for any idea that could solve the problem! I have tuned AUDI with the same injectors (846 bosch) and same settings on RON98 and had no problems. -- Have you tried to play with injector opening characteristics? Or play around with another set (smaller?) of injectors. Very suspectible. * Thanks for reply! Yes I have played with injector open rumpup time. Starting from 600us till 1400us. 1300us works best, but the problem is still there. Durning break-in i was using 330cc injectors without problems(the fuel was RON98 instead of ethanol). I have cheap ebay fuel pressure regulator and just noticed that I can feel with hand that it is pulsing, but built-in gauge shows stable 3.5Bar. Maybe unstable fuel pressure? Should i buy unit like Aeromotive? '''New Log !'''- www.bmwpower.lv/bin/0Jagr.xls Why it is starting to run rich at 28kPa, but is lean at 30kPa? http://www.bmwpower.lv/bin/VEE85.jpg http://www.bmwpower.lv/bin/3turboE85.msq Firmware: 1.1.18
