Is This Believable?

I had a conversation with the tech people at Baron's a few days ago relative to their BAK and and the VN900. They stated that the EFI on the VN900 can be used without and additional fuel management on the 900 (with the BAK only) based on their tests. That the air flow sensor and ECU were able to adjust correctly to the increased flow without any problem.

It seems possible, but I just wonder.

Any thoughts?

It has been mentioned more than once that with pipes OR an intake that the fuelpak isn't needed. It's when you combine the two that the processor becomes necessary. There is one poster on another forum who swears that even with the addition of both the processor isn't necessary. Personally, I don't put a whole lot of stock in that one.

Possible, but are they saying the BAK doesn't really increase air flow much? I went with 60ppi Unifoam in the OEM housing and added the Fi2000.

I ran my modified K&N without any fuel management for a couple of hundred miles. This should have similar flow to BAK or other aftermarket intakes. I checked the plugs and they were fine, no indication of running lean. The K&N alone made a very noticable difference in performance. I did put on a Cobra FI2000 later and have settings of 1 1 0. It made even more of difference in performance, but it also cost a couple of mpg lower on average. See link.

I haven't done anything with my intake yet, I have Hard Krome pipes and a Fi2000, but my gas mileage sucks, new stock filter and plugs. But can barely get over 40 mpg. The PO put the stuff on. I have been running the default settings on the Fi2000. If I got rid of the Fi would it help my mpg? Or should I just do the Uni-foam trick and hope for the best?

If your F12000R is using the default settings (4 2 0), that could well be your problem MPG wise.

I'm considering either the Cobra or Techlusion units, but one thing about the Fi2000R that struck me as strange was the default settings seem very high, especially the one effecting the cruise state fuel delivery.

If you look at RS900C very helpful post above, he is using the Fi2000R with a setting of (1 1 0) which seems consistent with the settings Techlusions recommend with their unit. A settting of 4 2 0 would be really increasing the pulse width, and the green or left pot ( the one set to 4 ) is the one that controls the fuel delivery while crusing or at constant speed.

Setting your green, yellow and red pot to zero should be effectively the same as removing the Fi2000R without actually physically removing it. I.E., it shouldn't add any additional time/width to the injector pulse.

Since you don't have any intake modifications, the amount of extra fuel required should not be too much if any.

Hopefully some of the people who have been so helpful to me will see this post and comment or correct any information I have given, regardless of how well intended, that is incorrect.

What you are saying is making sense. Cuz my pipes are starting to get carbon build up at the tips. So maybe running 1-1-0 would help.

I'm running my Fi2000R at 4-2-0 now that the weather has cooled. I ran 2-2-0 during the summer. With the 60ppi Unifoam filter and relocated air inlet it runs lousy if set any lower.
