    Using Siemens FI114962 60lb data for FI114961 injectors ?

    I have Gregs DVD's and the spread sheets but they don't have the ls1 injector tables. I used his 42 greentop data and it worked great but now need to upgrade to 60s and need some data for these FI114961 injectors. Hope I can us the shorty data on the spread sheet. I have down loaded so much conflicting info I am lost. Looked at many tunes in the repository and data is all over the place. So has anyone used the FI114962 data for the FI114961 injectors ?
    THanks

    FI114961 is just the "long 60#/hr" injector, which is the same as the FRPP -LU60 part number. Use that data, but it will require scaling everything to fit under the 8.0g/s flow limit of the older PCMs. This really isn't a big deal because if you genuinely need 60's on your LSx, you're probably also well beyond the same PCM's limit of 512g/s airflow.

    Thanks for the reply. Didn't expect you. So the FRPP -LU60 are the same as the FI114961 injectors except with the EV6 connector? I have an 06 GTO with an Older Maggie that uses the Ls1 injectors. Right now I am at 490g/s airflow and want to switch to E85. I see some 04's that are over the 8g/s flow but I see mine stops at 8.0.
    I guess I will watch your video about scaling again and see if I can grasp it. Your DVD's are great!. THanks!
