Default Tuning di for e85

How can this be done? Ready to start tuning on my ysi port injection setup but have never done any di tuning . What will I need to change to compensate for the volume of fuel I need? Or will it just "do what it will do" and I compensate with the port injection?

the di pumps and injectors even with a bigger cam lobe will leave you short on flow to make big hp on e85

I think di + PI is the way to go and you can add as much fuel as needed

tuning the di is a hassle too and the factory part throttle is good already and has lots of sweat equity there

take advantage of it and put another pump and injectors with another ecm and wide bands and you'll be happier

Matt at FSP did alot of work on this approach with a Haltech.

Default Thanks

My question was how do I tune the di injectors to support e85 to go along with my port injection setup. Do I even need to touch the injector data or just compensate with the port injection

Make the port injection do the work on boost or heavy boost and keep the he DI active well with drivability...
dont over think it

There is a few companies that have a plug and play setup for port injection
