Now the hot start and idle is solved, I still have a problem to start.

Here are the parameters for cranking.

Priming, crancking setup

Hot start primep temp scaling 20%

Cranking threshold 399rpm

Crank Ignition advance 9.0

Crank VE 60%

Afterstart setting (-40c) 12 cycles

Afterstart Warm Time (77c) 0 cycles

% of Warmup Enrichment at highest RPM 66%

% of Warmup Enrichment at 100kpa 90%

My crancking enrichissment curve is:

-20c 300%

0c 200%

30c 150%

70c 100%

Afterstart Enrichment curve

-20c 275%

IAC duty at crancking

-40C 85%

77C 42%

IAC reference curve just some points

-40c 60%

...

...

69C 23%

Any suggestion ?

What kind of injectors and fuel do you use?

Bosch green 440cc

- assuming on pump gas (?)

How starting is bad? Is it cranking forever, or firing some strokes but cannot rev up, or revs and dies? ...

It did not start at all, it is crancking forever, I must inject Ether to have a start and then it is OK.

Once warm if I stop, it can restart it is OK.

You should give more details, preferrably your full vemslog/vemscfg files.

Here is the log, I am obliger to put ether in the intake and press full trottle to start
