2 quick questions, and I've read the uberdata posts already. First of all, is it ok to use the injector multipliyer instead of selecting the whole graph then multiplying it? I get different numbers with both. Second, my numbers at around 7000rpm are like 888 for fuel, is this normal? Thanks.

the injector multiplyer does the entire map, and you don't need to highlite it. The reason you get numbers different is because its not multiplying the exact same amounts, but they should be close. The 7000rpm question is normal. however if you look at the duty cycle you are maxing those injectors out. You would want to go larger injectors if that is the boost you plan on running.

450cc too small for 10 psi? Can't I just adjust the fuel pressure or somthing to like 50 instead of 42? Actually, come to think of it, the boost fuel efficiency is at 120 which is appearantly really rich. I guess after tunning the 450's should run under 800. When I set it too 100 my max setting is 777. Is anyone running over 100 after tuning?

The reason you get differences is because the injector calculator doesn't just multiply, it also adds some in to counteract the time it takes the injector to open. Bigger injectors take longer to open.


888 is pretty high. Check out the überdata board, get a basemap for your LS. Good settings seem to be 105 efficiency and .7 retard per lb. Depending on the size of your turbo, the 450s should be fine for your setup.

Thanks for info. Where do I find the uberdata board?
