Well I installed my V2 last week after getting my car up and running, Im having a really strange problem. When i turn my car on, it seems to vaccum at 10 @ 1000RPM, I was under the impression that i had a boost leak,But after it warms up it will go to 20vac. @ 1000RPM. now i might have a small leak, still but not enough to get my car idling so ruff. also when warmed up when it drops to 800RPM. It vaccums at 17vac. but idles really bad like i have combo cams.i tried adjusting Airflow and can get it to STFM to 5.1 but my mid is still like 13 and such. My mods are Evo 560's and Evo 8 Pump. Evo 3 16g and my Global is -20 and dead time is at 0. If you guys need some other info on this please let me know. wanna get this fix.

P.S. if i install the stock ECU. the car Idles fine all day. no problems whats so ever.
 
You should post this up on the DSMLink forums.
 
Change the dead time from zero to the value listed in the DSM Link reference manual. A quick Google search will find that for you if you don't already have it.

The deadtime settings are correct at 0. They are Nippon Denso injectors from an Evo VIII (you can find them on the table):

Post a log of when it is happening and another one of when it is not doing it.
 
Post this up on DSMLink forums or give me your screen name on the DSMLink forums so I know this is a real DSMLink.
