Hi my car s2000 ap1 having issued starting some time it crack all day and don't start i have to used a boosted pack to started and its no tune issued , with factory computer it start right away.

 

I feel like English is your second language? If so, I understand what you're saying. If not, get the f**k back in school.

As to your problem, if you search around it's pretty common. I think you have to give the EMS a few seconds before you start cranking. I don't have the time to search around for you, but looking in to getting one I saw a few threads about this issue.

Google "S2000 AEM V2 starting issue" I'm sure something will pop up.

 

Get it tuned.
