    Been to Westec this morning to see how my coupe's running.

    Got up this morning and headed off to Westec in Newport (near the Cinema if your from there) as i'd recently changed my actuator and wanted to see how it was all running. It made 228 Bhp at around 5500 rpm and 245 lbs/torque at 3600 rpm. was fairly pleased with the graph as its improved over my previous one a few months ago, but still not liking the dips.





    Was running an A/F ratio of between 12:1 & 11.1 all the way through the power band. Is this slightly too rich or good? Can i adjust my actuator slightly to up the boost a little if i have some excess fuel to be burnt?

    An AFR of 14.7 is said to be the best allround ratio to have and it looks like you are running a bit rich, thats better than running lean!

    Torque graph is a bit bumpy, I expect you feel that on the road, who did your map?

    on a turbo car you reall want to be in th 12's on your afr. So dont worry, yours look spot on, mine are all in the 11's.
    324hp @20psi
    13.9@103mph 1/4 mile must practice more!

    Its supposed to have a EDS phase 1 map on it, so was hoping for a little more power, but fairy happy with how the car drives, you can feel the the dip in the middle definitely.

    Full engine spec is

    EDS phase 1
    Iriduim plugs
    2.2 airbox
    Lightened flywheel
    FMIC
    Front decat pipe
    Sports cat
    2 1/2 " exhaust

    Yep, a figure of 12.4-12.6 is allegedly the figures for optimum torque/HP on a turbo motor.

    I'd say the air fuel ratio is spot on. From my jap experience 11-12 A/F is perfect.

    14.7-1 is stoich thats how things melt in engines, around 12.5 would be a safe max with a good map on a turbo engine and around 13-1 on a good n/a map.
