Cold start after DBW upgrade

[ozyvr4]

Hi there . I have just upgraded to DBW on my VR4Link G4+ ecu . I had the ecu modified by LINK NZ. The was starting great on the old cable setup . I zeroed out all the necessary tables to set up the base warm idle. It did take a bit to start car on first try ( took 3-4 cycles of the key and it would just idle. I warmed car and did the base idle in open loop , I have just switched to closed loop as I was waiting for some time to do some logging of cold start . 

It is very hard to start that first time from temps of 10 deg C to 20 deg C . Once it does start I can turn off and it restarts fine. 

 

I was hoping someone could have a look at my log and file to see where I improve this. I thought as the old system was working great on cold start the fuel enrinchment would be fine.  

 

Car is a 1990 VR4 - Subaru Imprezza pedal - Bosch 74mm throttle body - 2200cc Bosch injectors on E85 - Can Lambda 

 

Any help would be appriciated

Your links take me to a page that says "file not available".  But if fuel settings havent been changed then it is most likely airflow related, so I would experiment with the start-up step.

I have tried adding extra in start up table , but Im starting to suspect that the throttle is opening more than my old setup so it may need more fuel in those areas. Im seeing 6-8% tps on startup. 

I have a base of 3% and 1.5% in start up table with 1% in the base idle at 10-20 deg C

 

I have tried to add my files again

I had play and added about 15% more fuel in the lower temperature areas of the Warm Up Enrichment table and it got a lot better. I'll retest again tomorrow morning when it's cold again.
