Hey!
Is there any way to calibrate tanks with Volvo Penta EVC without emptying them?
I had recall ECU Change while ago and our local "professional" Volvo guy ruined my tank calibration.
So now my tanks are showing empty all the time :mad:

He is saying only way calibrate tanks is empty them.
Is there any way to do that without emptying??
Boat is SC35 with 2*375liter tanks. (D4-300)

Anybody having EVC manual could you check.
Volvopaul u have any tips?

Thanks!

I'm afraid it's a dealer only calibration as the vodia tool is used to set the calibration, matt m on this forum has the same problem , if the wiring from the sender to the engine connection is broken the memory is lost, in my opinion a stupid way of calibrating a gauge or e c u , after all it's still good old fashioned ohms resistance from the sender converted.
 
fuel tank

You can go into settings and try a fuel tank recalibration. You will need to fill your tank up first then do it.

Sometimes I have found the system falls over and forgets. If that fails it will be like Paul said a service download.
 
Just a thought chaps but would removing the sender from the tank "fool" the system into thinking that the fuel was removed from the tank?

Like I said - just a thought.
 
If you start from scratch you don't need to empty the tank and stage fill it, just remove the sender if installation of tanks allows, then range the sender from empty to full while the vodia is attached set in calc mode.
 
Thanks for the answers. :)
Yes I can enter OEM mode in both engine displays and there is tank calibration part.
Problem is that only choices to calibrate tank are "full tank calibration" and "5 point calibration" but you can't enter them before you have set "empty tank".

Volvopaul do you know is there way to pass around emptying with vodia or do I have to empty tanks anyway? :confused:

Senders are in a bit tight space so it's not easy remove those and fool to empty position.

Edit. Thanks Volvopaul, I was writing my question when you allready answered. So I assume I have to empty them, if I could not remove senders...

One more question?
Do you volvopaul know is it possible to do calibration next way.
1. Drive my tanks to almost empty.
2. Empty port tank to stbo tank and set "tank empty point" to port.
3. Empty stbo tank to port tank and set "tank empty point" to stbo.
4. Fill both tanks and make "Tank full" calibration to both.

I think its not as accurate as multi point calibration but makes job easier?
Doable or not?

Had the same, I lost a tank according to the system. I was told that there was a bug in the update software which has now been fixed. Mine are new D3-170s. I would go back to whoever updated your system
 
This raises an interesting point about fuel gauges on SC35's. I have personal knowledge of only three boats.... all 2011 models. Each of these boats has had fuel gauge problems.
I say gauge but it is probably sender trouble. Om my boat the gauge for the starboard tank read full until it was nearly empty,
I complained to the dealer who said the boat was more than 12 months old and therefore it was out of warranty. I pointed out that from new the advice was to keep the tanks full to prevent condensation and the dreaded bug and I had only done one 100nm journey which used appreciable quantities of diesel so I had no way of knowing before. Tough they said it is a 12 month warranty and that has run out.
With that I pointed out the words on the gauge said VolvoPenta and the VP warranty was two years...very reluctantly the dealer said they would look at the matter but one of their staff told me they had had several problems with gauges on new Sealines.
 
First you don't need a Vodia, you go into the OEM menu and select tank calibration and use the empty tank method. You will need to remove the sender so that the float can go to the bottom before you confirm the tank is empty.
Have done this dozens of times with new boats that haven't been setup by the factory correctly and now the are on the water with fuel in the tanks. In fact I have a small tank sensor which I just connect to the wiring instead of the boats sensor to save removing the sensor from the tank, it fools the system into thinking the tank is empty, follow the cal instructions then reconnect original and hey presto it shows the true reading in the tank.
Very straight forward and easy to do.

Ahh but not all builders use the same tank sensors, thus giving different readings in ohms that then give different reading to the ecu, I have tried to reset a pair of d4 225s without success, I was told by dealer and other vp engineers it's a vodia only job, if it turns out it's not then I'll name n shame.

Never used a Vodia to calibrate senders yet, sounds like some dealers trying to put you off. It's time to name n shame.
 
tank sender

I do the same as Spanner man. Never needed Vodia to set up. I connect the sender at the tank end go into oem and set the sender at empty then fuel.

Normally sorts it.

The evc system should only be running a 3-180 ohm sender this is the euro one.

US senders read I think from 240-30ohm so EVC wont work with it.

Normally if the sender is not reading the black cable should t off to an earth. This sometimes gets forgotten about on an install and the calibration left to the pdc dealer.
 
Thanks everybody!
I'll take look again if I can get sender out and then sort calibration out in OEM mode.

Maybe its also worth to look if I can press sender down to empty position through inspector hatch.
If not, then I have to start "diesel-circus"...

I let you know how it went.
 
Sender access

Might be the best way as sealine put the sender on the stbd tank where you cant remove it!!!!!! unless the tank is empty and you pull it all out
 
The issue I've got is that the calibration setting isn't even showing in oem mode on the engine. The other engine shows up fine. Could this be a dead sender? I.e. doesn't show up in oem mode because it "doesn't exist"?
 
+1 to never needing a Vodia for tank calibration. Regarding MATM's problem of 'no fuel settings being visible in the settings section', if the system has been autoconfigured with a faulty or unplugged sender, it will disregard that part of it & not show up in settings. You'll need to check the connections & the sender, then re-autoconfigure to get the tank calibration settings back. Its all push button stuff, you can even short the 2 sender wires out if your desperate as that sends 0 Ohms to the EVC system & allows empty tank calibration to go through (remove shorting wire afterwards or it will always read empty!)

Full tank calibration can be performed when full if desired, and multipoint calibration can be done if the tanks are less than 20% full, and just following the instructions on the screen as you fill. Redoing the empty tank calibration after a multi point will reset the figures for the multipoint, so you will loose this more accurate tank data unfortunately & have to redo (or at least it did it to me when I tried it!)

Good luck

Your engines are first generation e v c I'm told which requires the vodia for some reason I'm told.

The sender is fine I tested it, it could be a wiring issue maybe a bad contact in the loom.
