I did the double the stoich, halve the IFR but can't find the IVT Terms where some say they are: Engine > General > Fuel > IVT Term. There isn't an IVT Term listed in HPT 2.24, so, is there something else that is supposed to be changed to match what halving the IVT Term would do on my LS3?
I have a 2013 Camaro LS3, twin turbo, ID1000's, LPE twin-fuel = 804/804 rwhp/ft-lbs
What's your version of 2.24?
You shouldn't have to scale a 2010 Camaro for ID1000s.
2.24.649
The IFR vs Pressure Delta maxed out after 73.7dpsi (delta pressure) at 127.0lb/hr. The ID1000's data hit 128.23lb/hr at 73.7dpsi then goes up to 156.405lb/hr at 111.39dpsi, so I scaled it. Reason I scaled was I was leaning out WOT at higher RPMs. I believe it helped, but then again, I'm new to all this.
Tune attached.
You'll likely never hit that pressure delta on a factory type fuel system, and if the car is boost referenced now, you definitely don't need to scale since it should be set up for boost reference.
Update your 2.24, and you should get access to the IVT.
Just updated to 2.24.1165. Now I see IVT Term showing up. Half the terms in AFR Term table, I presume?
Yes.
So, you're saying I may be wasting my time scaling my injectors because I won't hit any Pressure Deltas higher than 73.7psi? What is likely the highest d/p I'd hit with a maximum boost of 12psi, with the LPE twins pumping out 58psi, then jumping 63psi when both are pumping? If I'm not gaining anything, it's easy enough to revert back to stock settings (no need to do anything that isn't beneficial). TIA, this is a learning experience for me.
With 58psi in the rail, and let's assume the lowest MAP value you hit is 33kPa, you'll get about 68psi delta. In boost (12psi) with 63psi in the rail, you've only got 51psi delta.
Alrighty, then! Looks like best to unscale my Stoich/IFR/IVT and back to stock. Don't break it if it ain't broke (stock settings work best in this situation). Thank you, sir.
And the DSX Flex Fuel kit I got from you is working flawlessly. Between that and my Stage 3 cam, car's gained over 130rwhp.
