Double the stoich, half the injector flow rate, half the IVT terms.
Now you have a 127lbs/hr limit. This is a pretty standard way to get around this issue. Tuning in lambda is required.
good to know
5FDP could you explain that a bit more! Thanks
Not much to explain.
You have to in a way fool the computer so you can run really large injectors. If stoich is like factory you end up being limited by the small injector limit. In a crude way of saying it, if you double the stoich value the injector flow rate limit also doubles but need to half the flow rate because the table still stops you are 63.5lb/hr. So if you had 100lb/hr injectors that doesn't fit, so 14.68 now becomes 29.2 and the flow rate becomes 50lb/hr.
I'm not going to type out the stuff for IVT terms so read this thread on that exact topic.
