Hello,

I'm having a problem on my JDM DC5 when I press the clutch and let the engine rpm drop to idle, it is going past idle and almost stalling, then it sort of yo-yo's back up and down. Sometimes it will completely stall... othertimes it will just keep going, but the engine rpm can drop well below idle.

Map and Log attached

I have tried to adjust the iACV up and down and going down did seem to help a bit, but didnt fully cure the issue

Another thought was that it could be my fuel table, as when it almost stalls the S.Trim goes crazy and tries to take away a load of fuel?

Do you have a lightened flywheel?

No, OEM flywheel. Brand new clutch fitted just yesterday

Was it doing this prior to installing the clutch?

It's hard to say because the Kpro was installed at the same time. I'd say it is map related though as fueling changes have made it worse

It sounds like it needs to be properly tuned on the dyno.

I have same problem After mapping, not all time
When i press thé clutch, engine RPM down very fast.
Same problem with iacv ans not iacv well it's not problem.

I'm not quite sure what you mean.
