Default Plug-N-Play injectors for 100% e85?

Rather than get the injectors cleaned and still be limited to an e85 blend, I'd rather replace the injectors to support 100% e85, naturally aspirated.

Is there a recommended drop-in injector? I understand I'd still need to have a custom time for the bigger squirters.

Thanks. Sorry if this had been covered previously!

Bosch EV14 42lb 440cc work perfectly. Just the right amount of additional fuel on stock maps. Maybe a tad rich in some areas but it counts a lot more when you start eclipsing 8300 rpm.

As in I could install thesr injectors without needing an immediate retune?

No, you would spend a ton for an oversize all stainless injector and tune. E85 is hard on rubber fuel lines and o-rings for sure. For stock injectors and fuel pumps on e85 it is no problem.

Yes, you can get by with the stock tune but would be better in the long run if you at least get ignition timing advanced. If it's really really cold out, you may have delayed start with the factory starting pulse width.

I run 26° at idle and +3° for the base ignition map. Full load will be dependent on cams + final afr.

Hi Slim, first off, thank you for sharing all that you have with the S54 community, I've been super impressed by all of your projects!

I was hoping you could answer a few quick questions about using the 440cc injectors on E85 with the stock map? For those reading along, this is NOT a flex-fuel solution! It will only work with something near an E85 blend.

Ok, on to the questions. What Bosch EV14 injector p/n were you using? I'm assuming that it is still at the stock fuel pressure, due to the size difference between 440cc and stock, correct?

Assuming that the stock fuel maps are relatively close across the board, did you happen to experiment with cranking and after-start enrichment at colder temperatures? If so, do you recall what maps those are on an 54HP ECU?

Lastly, knowing what you know now, would you choose the 440cc or go larger and simply adjust the main fuel scalar?

Cheers,

-Doug

I’ve got a set of bosch injectors that are plug and play with our harness and fuel rail. They’re 627cc injectors that were made for the GT2RS. Only thing you’ll need is to get them rescaled with a tune.

Bumping this thread, would a Bosch EV1 42lb 440cc injector be a viable substitute?

They're quite a bit cheaper and the benefits of the EV14s don't seem to really matter at this size, from what I can tell...


Thanks for sharing though since I was wondering the same thing as op.
