    If want to do it right it need to be scaled ....

    Or u can use double stoich and cut the IFR in half ... ( not sure if this will work in ur 80lbs injector )

    or can i do the max the 63.5 and add the difference to the stoich ? Thanks

    You would put half of the injector value and double the desired stoich value.

    For example: 40 lbs/hr and 7.3:1 AFR

    No you want to go opposite:

    80 LB injectors = 40LB in IFR table
    STOICH AFR = Double so you want to take 14.68X2 so 29.36 afr

    Hope this helps, it works fine but your Fuel consumption on the DIC will be half too so looks like your car barely eats any gas when you set it to instant fuel economy lol.

    Thank you so much guys i'll try it.
    A friend of mine told me that there is an easy way instead of x2 the stoich. you can max the FIR and then add the difference to the Map table like let say i'll go with 80 size injectors 65.3 is the max and then I add the 14.7% to the Map table do you guys think that will work ?

    This is really the easiest way. It only takes a couple minutes.

    If you half the fuel density table your DIC will read correctly again.

    Sorry for resurrecting an old thread... but when doubling the stoich AFR and halving the injector flow rate, is the only table that needs to be adjusted the injector flow rate versus pressure delta? Everything else can stay the same?

    Hey CLM
    What I did is I followed Greg's Scaling DVD. I didn't cut half of the IFR and 2x the STOICH. but what I did is I scaled the whole tune MAF, VE, and Timing tables. it really takes time but in the end you will be pleased with the result.
