sorry the topic is not more descriptive, but i'm really not sure where the problem is comming from. i've got a jdm b18c in a eg hatch with a chipped p28 runnin crome. it seems that anywhere below 2k rpm, the engine cuts out when i tip in the throttle. below 2k i can't go more than about 1/4 throttle or it just cuts out. i'm pretty sure its the fuel because i first noticed it on the dyno when i was tuning it. i had to cut my session short because it scared me. it was going fully lean, so its like the fuel was cutting out. i didn't touch the fuel map that low in the rev range. but just to be safe i went back to my base map and it still does it. so i'm kinda lost. any help guys? oh yeah, no cel's

 

Check your timing and make sure it's not off a tooth.

 

its not

 

sorry to bring this back after so long, but i just and a new baby(well my wife did) and i've been busy, and i still need help with this, i was thinking the other day about spark timing, that COULD cause it i guess, i dunno, i'm trying to figure out anything here. please help

 

CELs?
