Cold Start Problem - Pls Help

Hi Guys,
ive a problem where during cold start my engine seem to be easily dies off whenever i move the car. Ive to give few rev and only than the car could drive normally. Its just happen every time on the first start of the day. No much issue after that unless the engine is completely cold down again.

Which area should i tweak on the ecuflash?

Thanks a Million Guys

Usually not fully warmed up engine stalls because of extra rich fuel mixture as the fuel is added up during warm up operation. Try to give it more time for warming up and see if it will change anything. If that is the case you will need to either reduce your fuel delivery around the idle zone ( by slightly decreasing values in top three cells of MAF smoothing table) or increase ignition timing by a couple of degrees in the same zone ( 10 to 30 Load, 500-1000 RPM).

Thanks Guys but its seem to be lean issue.

Will increasing the latency figure helps?

I would not do that although it can help. Instead I would increase the MAF smoothing table value to add more fuel at the proper air flow frequency.

In this case yes, increase the latency.
