That's exactly how I plan to use the switchable maps. Thanks for consolidating the resources needed! Your the man. ...I'm also going to need to get a more local E85 pump here.

If there were E85 pumps available here, I'd skip the alky kit all together. I can't wait to see the map switching interpolation finally working.

I was thinking of using theTephra v5 to run one e85 map and then what would be cool is to have the flash cel on knock mod be able to trigger a switch from map a to map b instead of the cel light. Could Tephra wire code to do this?
this has lots of different possible applications.

regardless I am really happy that there will be a E85 within 3 miles from where I work

So you want it to switch maps when you get knock?

Don't forget, E85 is a FARR richer AFR than pump gas so if you plan on using E85, you'll be needing larger injectors if you dont have them already. Its roughly a 9.7:1 AFR for stoich and around 7:1 for WOT boosting (if memory serves me).

I cant wait till this is finished that still sucks about tephras car hope he gets it all figured out soon wish i had the cash now to donate and help him out BTW how big of injectors i was planning on going 725 to achieve the horsepower i want roughly 500-550 would i need bigger if i ran E85?

yes. I would get at least 1000-1200s.

I'd recommend 1000cc's for 650 crank HP like you are shooting for....but thats for regular gas. Most HIGH HP guys running E85 probably use a secondary injector setup (4 additional injectors) for daily drivers so the idle is more controllable. You'll see people running high HP E85 cars with 600-750cc primary injectors and 1000-1200cc secondary injectors which only come on when boosting.

wow really crazy i should stop listening to the guy i use to he told me that for 550-600 at the wheels that 725 would be good lol i should try to commit the formula for figuring out which size to use to memory

450 whp is probably a realistic upper limit for E85 without using secondary injectors and a dual fuel pump setup.

Is this working now or is it abandoned project?

The idea lives and works
