I'm looking at a few hptuners files, and some OSs appear to have these tables defined, and others don't.Is there a way to modify the fuel range on the instrument cluster with an HP Tuner?
It's full and says 384 miles until empty, which I know is nowhere near correct, considering the tank is nowhere near it's OEM size, that it thinks it is anymore...
It'll probably be a few days before I can get you what you need? All that is beyond my comprehension,I found all these tables in a E67 / 2007 / 2.4 model bin file, so it should translate over more or less directly to yours.
Big thing will just be scaling the Sender % to actual fuel in tank.
Can you log Sender % in VCM scanner? A good way to go about it may be to run it empty. add a gallon at a time, or whatever increments you can measure easily. And basically just build out that table. You can also edit the axis values which makes it a bit easier/no interpolation required.
Logically this should fix the issue, but won't know till we try, there could be other funky stuff that the cluster is doing. And if fuel volume remaining is now reading accurately...the distance to empty etc should all just work.
Send over your current HPT file if you have it, and I can make a few small edits just to make sure I can find the tables and if these changes will actually do anything. PM or email over if you prefer or can't post here.
Don’t forget to factor wheel size into all of this or the mileage still won’t be accurate.
Oh? I guess you could put foam chunks in the tank, like I've seen some racers do before, but that'll probably be a lot of trouble?And as further warning, if you let the tank get much below 1/2 tank and pitch it hard into a sweeping turn, you may get some missing due to full slosh. I pretty much just keep mine above 1/2 tank.
How can you edit the file to add in the Fuel tank/gauge section? I don't see it in my base tune file.I'm looking at a few hptuners files, and some OSs appear to have these tables defined, and others don't.
Can you post your file? If it's not defined in yours, I can *probably* get it added and modify it for you if needed.

Usually through user defined parameters if using hpt.How can you edit the file to add in the Fuel tank/gauge section? I don't see it in my base tune file.
Yeah, user defined parameters. Lets you create your own definitions (xdf format) and basically edit anything in the calibration block(s) that aren't defined by HPT. Kind of a workaround to asking support to add stuff, if you know how to find tables etc. Unfortunately it's a paid feature and linked to my MPVI, so only I or other UDP enabled devices can bring up this function to make the edits.How can you edit the file to add in the Fuel tank/gauge section?

You won't be able to see the table since it doesn't have a regular HPT definition.Oh, that's very cool! I've been playing with HP Tuners and had no idea about user defined parameters before. Could you reshare the file with the edited table in it?
If you have some ballpark figures you want to fill in, let me know and I'll do it and post the file here.Oh, that's very cool! I've been playing with HP Tuners and had no idea about user defined parameters before. Could you reshare the file with the edited table in it?
It looks like I've got a 10 gallon tank, could you use the same the ratio that you have for the sender % and scale it down to the 10 gal capacity instead of the 13.5 capacity that I see in the screenshots?If you have some ballpark figures you want to fill in, let me know and I'll do it and post the file here.
Since I don't have any real data to go on, I'm not sure the best way to scale the whole table, so here's a couple files to test out.It looks like I've got a 10 gallon tank, could you use the same the ratio that you have for the sender % and scale it down to the 10 gal capacity instead of the 13.5 capacity that I see in the screenshots?
