I have a lightened flywheel and 15 pulley and it hasn't been mapped yet but runs as normal except it needs slightly more revs when pulling away from stand still.
mine was OK with the SMF before the cam was fitted.I have a lightened flywheel and 15 pulley and it hasn't been mapped yet but runs as normal except it needs slightly more revs when pulling away from stand still.
It's not the idle that's the problem. When the engine speed reduces the lighter flywheel has less stored energy, with the clutch pedal pressed down the revs drop quickly enough that the ECU doesn't catch the engine at idle speed and it dips below, sometimes enough to stall.lighter flywheel might speed up the idle more than slow it, less drag
Still makes me wonder if the bypass valve is not opening quickly enough? has it been cleaned, I know it’s working.It's not the idle that's the problem.

Leave the car standing idling and it is OK, it will not stall.
ok gotcha, read the above as a low idle more than the 'return to idle',It doesn't hold it's revs at idle when hot. Start it up after it's stalled and it ticks over fine. Changed the throttle body but it has made no difference.
I had wondered about that. Need to investigate the ignition system first.maybe time for a leak test....
I have to change my injector seals, and have a bigger intercooler too. Are the injectors generally hard to get out, or were you just unlucky?Car still being a pain. My C310 reader says cylinder 4 is running rough.
Two new MAP sensors and injector seals (pain to get the injectors out) fitted. No change.
They can be tight. Give them a wiggle back and forth and use WD40 to free them. Take your time and they will come out. Better if they come off still attached to the fuel rail, but you may have have to unclip them from the fuel rail so you can wiggle them more if needed.I have to change my injector seals, and have a bigger intercooler too.
