Thread: Changing to LS7 MAF, how does this look?

    Changing to LS7 MAF, how does this look?

    I tried my best to copy the LS7 MAF values to my LS1 tune since I'm switching to a card type MAF with c6 Vette intake. How does this look? Should I smooth it out a little better? the rx7 tune is the one i copied over from the stock 08 Vette tune.

    Also whats the easiest way of really smoothing it out? just individually select sections and click smooth section?

    Well, picking a spot value of 7000Hz (just to get an idea):

    '99 standard LS1: 100g/s
    My LS376 with the mods in my sig: 154g/s
    Your latest table: 197g/s

    Since I'm no expert either, not even an internet expert, lol, I'm not sure but it would seem yours is high (your whole curve is considerably higher than mine).

    I changed it to LB/H instead of G/S because thats the column units the 08 Vette used. It is matching the Vette values pretty close just slightly high. Is there a button to take all the numbers and reduce them all by a small percentage?
