ok here we go. i got my prelude out of the shop yesterday. here is everything done this time. jdm h22 turbo'd. i had mahle h22 pistons;eagle rods;arp bolts;all new everything in the engine;head machined;780cc injectors;i have hondata s100. ok so the guys put a base map on my ecu set my boost at 1lbs. just untill i break it in, then i am going to get it tuned. so here is what its doing. it stalls out when i am not moving.ie: when iam at a stop light. it will idle for a min or two then die. starts right back up.then few min later same thing. this is only when i am stoped. i am going to change the feul filter today at lunch maybe that will fix it. but could it be the base map? what else could it be? any ideas?
