Wolf 3D V4 Load Table psi values

V4 Load Table psi values
I've been reading the V4 Manual quite a bit, still deciding whether to upgrade my V3.1 to a V4, or go Haltech.
One thing I like about the Wolf is that the load bands are scalable, depending on what your max boost is. But the thing I can't figure out is what PSI each load band represents. 107 is 23 psi, 100 is 20 psi.
So am I safe to assume that each load band represents 3 psi and that 0psi is 50% load?
That would be a lot of Vacuum bands..my v3.1 only had 2 in 21 psi mode!!!!

If you are trying to match the load bands to your boost gauge, it's never going to work out correctly because the boost gauge is psig and the load bands are based on psia.
I think you are reading too much into this.

EA, do you know if the 107% band always stays at 23.5 psi, no matter what you scale the other bands too?

it would make it much easier for all, at least that's what i'm used to.

Also, some EMS products display vacuum and boost load values based on a fixed static value in order to aid their target consumers. Sometimes I wonder if these incorrect values hurt more than they help.

The V4 Wolf software has a calibration function for its on-screen boost/vacuum gauge so you can set it to your boost gauge if you like.

I dont think the load band settings are difficult at all,whilst you are tuning , if there is a certain point you want to capture,just npress the little S icon with the line through it and it will stop at that point...The load bands are also there as for what evil wrote about using a MAF or TPS. If this was such a bad idea,i dont think the trust E-Manage or the Haltech interceptor would be utilising the same idea...

IF 107 is 23 psi what is 0? what is it in vacume? I only ask beause I want to set up my Innovate LMA-3 kit to log in the same format for less headaces

think of it as percentages of a maximum that you set. If you set your maxium to 20 psi (which is what i would recommend for any boost application, so no recalibration is needed if you decide to raise the boost) then 100% = 20 and 0 = infinate vaccum. ~43 ends up being atmosphereric, and if you do the math... 100 - 43 = 57 percentages that operate in boost. if you divide that in half, and add it to atmospheric (43 ) then you'll get 10 psi. 57 / 2 = 28.5 , 43 + 28.5 = 71.5
so 71.5 would equal 10psi
85.75 would equal 15 psi
57.25 would equal 5 psi
if you set the maxium to 15 psi, then all of this changes because 100% now is 15 psi, but 0 is still infinate vaccum.
for n/a models you set the maximum to 0psi because you don't ever plan on making boost. you will have 16 different load bands from infinate vaccum to atmopheric.
so 71.5 would equal 10psi
85.75 would equal 15 psi
57.25 would equal 5 psi
if you set the maxium to 15 psi, then all of this changes because 100% now is 15 psi, but 0 is still infinate vaccum.

Why not take an air pressure regulator supplied with shop air (from a compressor)
tied in to a gauge,and plug it in to the map. Dial in your pressure and check it thru
wolf interface. this is how i calibrated the gauge, and maped psi to load points!!!

Upgrade to a 4.0, the 3.1 just doesnt have the control you need to make the car run well in all respects (not enough resolution). You can get a discount if you upgrade to 4.0, and you can pretty much keep most of your 3.1 harness if you like ....

I did this and came up with the attached chart.
