VersaTuner Support for High Flow DI Injectors

[roli1206]

Okay I think I see what happened, a bit of an understanding error on my part. The VW EA113 HPFP internals being mentioned are the APR internals that are available for the MazdaSpeed because they were produced by Hitachi for both our platforms with minor exterior differences but the same internal specs. There is not a retrofit of an actual HPFP from a different vehicle (also this VW one was more expensive than a new one from Mazda, so not even worth it to save some $$$).

As for the roller bearing tappets that’s interesting to know that it can be retrofit, but I don’t know if there is anything to gain from that other than maybe some reliability and less wear and noise.

If I’m still mistaken let me know, but that’s what I gathered from some research based on the link provided.

you can run safely more pressure more reliable like i said there are upgrade 170-180bar vag fprv they need some work to fit on the speeds

and i got a custom hpfp in my car (totally useless in my case ) which flow more and should also can deal with the pressure but i don't have the financial capabilities anymore to finish everything

but if you have enough money you can fit a xdi pump for 2-3k if you would like more pump

Had a pretty good discussion with XDI over email, and the provided way more information to some guy on the internet than I was expecting to get. That said, they did want alot of it to be kept confidential, but here's what I can share outright:

They expect to ship a working product sometime this summer, and expect it to cost around $1200 (assuming market conditions for materials and the like don't swing heavily).

Honestly, yesterday me scoffed at this potential new product, but today there's some excitement in my veins.

I believe that the final holdup is tuning, but I could be wrong on that. @steve@versatune , any further input or info?

We have provided XDI with all of the injector data we could find in the ECU.. We are committed to making larger DI injectors work.
