I found this website as I was looking for idea's for a fuel injection setup.

Anyone hear of this company. Seems like a pretty nice setup but as I read on into the page about the setup it says that there is no tuning needed as the mass air flow sensor that they have is already calibrated for your setup and it will do all the adjusting your setup needs. I know the mass air flow tells the computer how much fuel the motor needs from the air going in but no tuning? I am kind of confused. Not sure if this is another cheap setup or not. Any opinions?

 

Yep there is lots of advertising in the Hotrod mags, and Hotrod tv also did a test on there system. They were one of the efi units tested in last months Hotrod magazine etc. Seems like a decent system Just my thoughts.

 

Yeah I seen some of the write up's. They had links to the articles on there website. I just dont know about the whole "No tuning needed". How can they get it correct with out a fine tune?

 

Wide band 02 sensors can really take the hassle out of tuning, you'll still have trouble with stuff like a big camshaft that throws the sensor off, but being a MAF setup might compensate for that a bit better. Just look at the LS1 setups, they can do alot of adjustments on their own.

 

Mass Flo uses a factory Ford mass air ecm to control it. They take a Mallory or MSD hall effect distributor run it into a TFI module and voila cheap cam sync. With some rearanging of the injectors on the wiring harness and tuning in a different firing order you get a cheap sequential injection. Ford used EEC ecms in their F1 program! I was skeptical about the self tuning abilites, but my good friend has a 85 Capri with a 351W, RPM Heads and a lumpy cam and it runs real strong on a stock tune. In fact i'm just starting the conversion on my Camaro. I'll keep everyone posted.

 

They are FAR FROM self-tuning and run MUCH better when tuned. The Ford EEC MAF setup is more forgiving, but definately not perfect.

 

I'm quite aware nothing is self tuning. I was implying that with a stock tune you can have good results with a way off stock components.

 

Here is a video if it. http://www.youtube.com/watch?v=u9lCYNnT1e0

 

This belongs in DFI/ECM. Moving..
