The system you saw for sale is an Accel DFI system, and they can be difficult to work with. Its a good deal price wise, but not easy to set-up or tune.






OK Dragula.... I still don't get this!
As I said, I'm no EFI expert, but the Accel gen7 stuff is just as straightforward to set up as the FAST systems you like is it not?
What's the difference?

Tuning the Accel is different software, but to me, from what I have now seen over the years, it's just different programs but the same basic approach. Both seem easy from what I have been able to see....

What is the big difference?




The XFI is a lot easier to set-up and is not the same as my classic FAST or your system. It can learn the fuel map based on some run time which reduces the need for logging hours on the computer or dyno to sort out the base VE.

I started out with a based map from another engine, non-hemi, and went from there. I had no prior efi experience, and did a lot of research on it before buying a system. Then I had to get the intake ready and I went from there. Like you, I also tried to hide some of the wiring and sensors and make it nice and neat.

I have run this system on a number of hemi configurations, and getting the base VE right where it needs to be takes time and effort. If you change a basic parameter, that effect the entire map, your back to tweeking it again. The newer systems are easier, and will 'learn' the base VE as far as I know. I think that is a really big advantage in my eyes, but since I have not run one of the newer systems, I can only go based on what I have heard.
