Volant Problems?

Hey guys,
I recently bought a Volant system and have had multiple issues with it. I talked to the distributor and they are refusing to return because they have no issues "documented." The rep said if I could find sources listing issues with the system it might warrant a refund and return.

That said, has anyone running or ran in the past a Volant system and had issues with it? What were the issues/how did it affect your truck? I've heard from a number of people this system makes our trucks run lean, etc. I will also be running this by the VP of Volant as he is not aware of any issues either.

Thanks for any input/help.

 

Not a single problem, runs great and only paid 240.00.

 

If your worried running lean get an aem wideband, unless your forced I don't see any problem, plus you waste money on NA motor.

 

I ran one for a while. Make sure the couplers are seated and sealing. Next, look close at the sealing of the MAF sensor. Any air leaks around the sensor can possibly create problems.

I never had issues or check engine lights come on. Should be an easy fix.

Probably be helpful if you posted what your issues are.

From what I've read the Volant can throw codes due to induced MAF sensor error. The Volant intake tube, at the MAF sensor location, is a different diameter then stock. The ECU calculates the actual air grains using the MAF sensor reading and the intake tube cross section (I think this description is right...). Since the Volant intake tube differs from stock, the ECU calculates the wrong amount of air and shoots the wrong amount of fuel. This can cause lean A/F ratios, and can cause a code to be throw if it gets too lean.

Many running the Volant aren't throwing codes, but are still running leaner then they should. Only way to truely know is get a reader (Scanguage, Ultraguage, iPhone app) that can show A/F ratios and fuel trims. If the fuel trims at WOT are showing large positive trims, then the MAF reading may be off due to the intake tube.

 

Just installed one a few days ago, and then almost eimediately after, hooked it into a snorkel. According to my OBDII reader, i'm not having any AFR issues with it, before or after the snokel.



altered connection point for the snorkel

 

Are you looking at the AFR or the fuel trims? AFR may still be OK, but fuel trims could be high.

 

afr. i'll check out fuel trims

 

I installed mine about 3 weeks ago now. I did have issues when I ran it for the first time. My truck acted like it was gasping for air. Buddy of mine owns a mechanic shop and he came over to take a look. Everything seemed to be fine, we took the cover off that you would connect the Ram air scoop into and it runs fine now. I don't know what it is about the fender hole, but it wasn't getting enough air.

My 2 cents.

Thanks

 

Did you (OP) used to have a SWB XR?

 

No problems with mine...

What he said in the first sentence.

 

I have a MAF calibrator on the way, and was speaking with Gadget to get the MAP for the volant intake. he sent me the following email. so there are at a minimum, rumors, that volant has changed something on the new intakes going out.......

"Here is our Volant map.

I have heard that Volant may have fixed the problems with their intake. If that
is true this map may not be proper for it any longer.

With your scan tool check the fuel trim deviation at idle and a steady 60 MPH on
flat ground. If they are heavily negative you should be fine with it."


I just added the fuel trim screens to my monitor, so i'll check them at idle and a steady 60 on my drive home this evening and report back.

 

You can already see the difference in the tube and maf location between the new and old.

 

I got some fuel trim readings on the way home from work today as well as some idle readings once i got home and the engine was warm. i'm going to do the same thing tomorrow on the way to work just to confirm the readings, and then i'll post the results.

is yours the old or the new? i just got mine, but i have no idea if i got the new or old version

 

Mines for the 12-13 year. On my engine bay pic you can see where the maf is before the elbow. Looks like the older version has the maf right before the throttlebody.

 

so here's what i've got. i am using short term fuel trim for banks 1 and 2. if that is the incorrect number to monitor, let me know and i'll change up my reader to display what it should.

at idle, with a warm motor, the fuel trim fluctuated between about -1.6 an 2. there were obviously a couple fluctuations above and below, but not near frequent enough to be included in the average range.

There was more fluctuation at a steady 60 mph on flat ground. at that point, FT was generally staying between -3 and 3, again, with ocasional spikes (more spikes in the positive than negative).

for refference, here is a screen shot of my monitor. this was a snapshot at idle. didn't want to fool around with taking one while buzzing doen the highway in rush hour......

 

LTFT1 and LTFT2.

Those should be on display as well.

 

10-4, just added.

more readings on the drive home this afternoon

 

Those are more crucial for steady cruising and idle. They will show you how accurate the MAF signal is, by how stable the numbers are.
