    Thumbs up COS5 N20 Settings??

    OK, I am installing a HSW Wet Plate Kit and have my PCM pin 56 setup to a switch. I am using EFILive 7.5.3 COS5.

    Here is what I have so far on the N20 settings:
    A0011 Set to N20 Monitor
    A0015 Set to 1.2 0-8K
    A0016 Set to 19
    A0017 Set to 3000
    A0018 What should I set this one to. MAP 30??

    Added:
    A0012 need to set to 0
    A0013 need to set to 0


    Please let me know what I should be setting the above calibrations to. Are there any other setting that need to be changed?
    Thanks,
    Bill

    Hi Bill

    You can also just run the ground to pin 56 with a second relay from the Nitrous arming switch...saves having multiple switches.

    I have only just started playing with Nitrous, If its a wet shot you need to not worry to much about the VE table.. just change the Jets in the fuel nozzles, I plan to make some minor adjustments with the A0015 to get the AFR's exactly where I want them.

    A0016 actually reduces the timing by whats in this table...so you want to pull 19 degrees out?
    my A0016 table varies between 3 and 4 degrees thru out the rev range.

    Hopefully some of the more experienced guys with NOS can help with some of the other questions.

    A0016 was set to 19 by default. I changed it to 6 degrees. It is a wet shot. I changed A0015 to match Beers spreadsheet. Where do you have A0018 set to? I set it to 30.

    Thanks,

    I will know more later in the week when we can get access to a Dyno.
    I would imagine A0018 set to 30 would be fine as long as the A0017 is set to 3000rpm.

    Use a VE multiplier of 1 A0015 for the first dyno test then insert your real world values...

    What I have in that sheet reflects my dry 50 and wet 50 dyno from AUG, I have not tested the sheet yet, what I would do is use 1/2 of what the sheet tells ya to make sure the AFR is changing in the direction you want it on the following tunes, and then walk it in.

    BE SURE TO SET A0012 and A0013 (valet mode speed) to zero or else the timing retard will not work!!!

    Thats a important bit of info! Glad you passed this, I would have been pissed, had I got to the dyno and could not get it to work! Mine was set for 512 and 512

    So A0011 to Monitor N2O and A0012 and 0013 to zero?

    I never would of thought I would have needed to set those since they are for valet mode.
