Emerald map tweaking. Advice needed

[Tigger]

I'd like a little help with tweaking my Emerald map.

• 1.8 K-series
• Jenvey MTB's 
• Bernard Scouse airbox
• ​285H Cams with verniers (Timing is OK)

The map is pretty good when the coolant is warm (above 60 degrees), but below that when blipping the throttle the engine stutters or dies.

Cold start is also OK, and if I raise the engine speed slowly it seems OK but it's when I blip that the engine hesitates.

I've uploaded a clip to youtube of the live adjustment screen https://youtu.be/ba4QORMqVo4 and you might be able ot hear the engine.

I probably need to make an adjustment when the coolant temp is below 60 degrees and have read through the Emerald crib sheet http://www.emeraldm3d.com/media/software-manuals/Emerald%20K6%20IACV%20&%20Cold%20start%20crib%20sheet.pdf but before I fiddle I thought I'd those who know better than me where to start.

I'm drawn towards 'RPM Correction for coolant enrichment ' being the thing i need to look at. Any thoughts or advice warmly received.

Thank you

Hi Tim,

I've done a fair bit of fiddling with Emeralds, if you would like to send me your map I'd be happy to look at it and advise/modify it as is required.

Did you find a solution to this? My factory-standard sigma seems to be doing exactly the same!
