    first start up

    i just finished putting my new motor together with twins

    now i need to get everything sorted out to start the car and begin tuning

    my plan of attack was to apply a 2 bar OLSD OS, insert the data for the bigger injectors, and try to start her up, and then sort out the idle tuning.

    does that sound like i am in the right direction ?

    also, if my car does not have narowband sensors plugged in, the computer will go straight in to open loop mode correct ?

    my car already has a wideband installed.

    also what would be the ideal AFR for a turbo motor need at idle ?

    i am just waiting for my copy of hp tuners pro to arrive in the mail and i want to have all the steps worked out by then.

    any help is greatly appreciated

    i don't know that you'll go into ol just because the o2 are out it will more then likly just throw errors you should set the tune for open loop disable all trims and set cl enable to highest it will go. the AFR will be the same as stock 14.67 or so when your not under boost then 11.6 or so under boost but this is dependent on how much boost how hot is it what fuel. 11.5 will be good to get you going thu.
