Setting up SVO 30# injectors... The formula in the users manual for bigger fuel injectors is:
Rating New=(sqrt(PressureNew/PressureOld)) * Rating Old
For the Svo30's is that going to be 36/26=1.384 ????? If your old injectors flow 26 and new one on C5 flow 36.
Would that be the value added to the VE table? Can you send me the flash file on your car....I think you have the big injectors....? Thanks.

Re: Setting up SVO 30# injectors... The LS1's are pressure rated at 58 psi, the SVO injectors are rated at 39 psi... So, actually, it would be:
SquareRoot(58/39) * 30# Rating
Which makes the 30# SVO injector rating a 36.58 lb/hr at the higher LS1 fuel pressure.
Now, take this value (36.58) and divide it by your stock injector rating (for example, 28# for my '98Z). This gives a multiplier (for me) of 1.306... Then I'd go to my Injector Flow Rate table in LS1_Edit, and multiply each value in the table by 1.306 - and that would do it (in my case). <img src="gr_stretch.gif" border="0">
Once that's done, observe the LTrims closely to make sure the constant is 'close', it may need a little further tweaking, but it should be pretty dang close.
