setting timing on sr20det

i adjusted the CAS on my sr the other day, i was curious on what i should have my idle at when i set it to 15 BTC, i had it idling at about 840rpms with the tps unplugged and i managed to set it exactly at 15 BTC, should i be fine?

someone said it HAS to be idling at 750rpm and set it at 17BTC

yeah just unplug tps, get that shit and 15*

and then adjust ur idle accordingly via IACV. there is no specific idle number 750-1000 is fine....it needs to be higher to compensate for cams and such.
