Good morning, I am new to the forum and new to diesel trucks. Please bear with me. Yesterday, I purchased a 2008 F350 with a 6.4L. It came with an installed H&S Mini Maxx, but I will confess I had no idea what it was. I was trying to figure it out and was pushing some buttons.

Unfortunately, the story is now that if I shut the truck off, the truck will not restart. The electrical system will turn on, but it will not crank. When that happens, I have to go into the Mini Maxx, reinstall tunes--which takes about 15-20 minutes--and then I can start the truck. From then it's fine. Regardless, it is very frustrating.

So, I would appreciate help with the following:
1) does anyone have any thoughts on how to address this issue? Has this come up before? I have searched the forums and so far haven't found similar issues.
2) It appears H&S performance is out of business, so there is no one I can call to talk about this issue?
3) Is it possible to "bypass" the tuner and return it to stock (not a stock tune, but actually run it without the tuner involved at all)?
4) If I cannot figure out the Mini Maxx, is it easy to switch out with another tuner?

Any assistance would be helpful.
Thanks.

Odd...it seems the forum has changed, as I use to use it daily, but have used it sparingly for some time now, and usually when a question was asked, it was jumped on right away with several folks giving their suggestions/advice! Anyway...not sure which buttons you pressed, as I have the Mini-Maxx myself, and have it set the way I like it and rarely need to touch the buttons, but in reality, they are there to use, so you 'should' be able to use it as needed! I've had to delete the odd 'check engine light' lately, and I sometimes will change from a mild/stock setting to a higher one, but not often.

IF, your truck is set up with a 'delete' setup (exhaust/engine) no, you can't. If you truck has the cat convertor in place (not sure why they'd install the Mini-Maxx if that where the case) and the rest of the emissions system, you quite possibly could!

I would have thought, the crew from Mini-Maxx would follow their own forum at least, but possibly not, as I haven't had an issue with the programmer, to have the need to ask 'them' a question? There are lots of these programmers out there though, so I'm pretty sure there are folks that would know the answer to all your questions, so hopefully that will be the case!

YOU HAVE TO RE-INSTALL IT EVERY TIME YOU SHUT THE TRUCK OFF?

OR IS IT INTERMITTENT?

 

[untuned]

if the DPF is missing....straight piped....then at one time it was set up correctly.....sounds like the truck came with instruction and files.
h&s has been off the "air" for a long time....no help there.
these trucks are "older" now, so help might be minimal....the old race tuner was considered the best before the epa shut them down.
try these people for help ... freedomdieselperformance.com ...855-432-4733 they still advertise mini maxes.

 

[untuned]

if you want to try another tuner, email jeff at Spartan....a really nice and helpful guy [if he is still around] .

explain whats going on ...he can maybe stop the mini max reload from being a pain....or sell you on Spartan :grin2:

 

[TD-5]

did you get this sorted out?

 

[Powerstroke2000]

did you get this sorted out?

Yes...would be nice to know the outcome!

With a code I am getting continuously, the dealer says their is a TSB to rectify the problem. I mentioned I had a programmer, and they said perhaps I should see if 'they' have a update which in effect takes care of the same issue?
Now, I'm not sure how to get this 'update' for my H&S Mini-Max, or whether to go ahead and have Ford do 'their' update, and then try and re-enter the info from the Mini-Max all over again?
I've been leaving this for some time now, not quite sure what to do?

Advice/suggestions?

H&S tuner support from H&S is gone for good. There are vendors out there that can offer some support though.
If I recall your issue is with a P0088 or P0087 code related to fuel rail pressure deviation.
There was an adjustment to the H&S Mini Max programming for P0088 at TV # 6.4.18
There was an adjustment for P0087 at TV #6.4.32
As long as your tuner version is above these, then there are no H&S updates that would help with your problem.

The Ford "update" does basically what H&S has already done with these two parameters, which is increase the allowable deviation before the code will be set.
The original factory setting for P0088 (deviation high) was 3% & H&S raised it to 8% for the MILD & HD300 tunes
The Original factory setting for P0087 (deviation low) was 5% & H&S raised it to 10% for the MILD & HD300 tunes.

For example if the ECM is commanding 20000 PSI rail pressure & the pump is actually delivering 21600 PSI or higher( 8% ) then the P0088 DTC would be set
If the ECM is commanding 20000 PSI rail pressure & the pump is actually only delivering 18000 or less ( 10%) then the P0087 DTC would be set.

The "EASY" tune retains the factory settings of 3% & 5%

If you have the H&S "MCC" custom tuning program the parameters are accessable & adjustable

But in the end, If your tuner is up to date & you are running say the H&S "Mild" tune on the "Tow" setting and you are getting these codes your HPFP is probably unhealthy.

Thanks for the update...much appreciated! Yes, it was the P0087 that seems to be the culprit at my end. As far as I can remember, I don't believe I've ever updated my Mini-Max since I bought it, which would be 4 or 5 years ago now! It's worked fine, thus I've had no need to update, and it's only now that I've looked into trying to figure all this out, and didn't realize H&S has basically disappeared. I know they use to have a wonderful forum themselves, but that doesn't seem to be the case now either.

I don't quite understand the "TV #6.4.32" you talk about...is that the Mini-Max version? Perhaps I'll have to figure out how to get that information....there again, help on Mini Max in general seems to be a hit and miss proposition! Do you know where I'd get this 'new' version, if mine is outdated?

As for 'when' I get the code, it's in all and any setting, from stock on up. I've never had 'any' hesitation fuel wise....just a loss of cruise control, and occasionally what sounds to be a can of marbles vibrating sound...if that makes any sense. Turn the truck off, when I restart the sound is gone! I would think if there was a true fuel related issue, there would be a hesitation (lack of fuel) but that's never been the case for me?

Thanks again...nice to hear that someone at least seems to have the knowledge of the issue!

The TV# (tuning version) of your tuner is on the "settings" screen of your tuner. See the attachments on how to get there.

Just to clarify; There are 3 tunes on the Mini Max, "EASY", "MILD", & "HD300". Each of these tunes has 4 power levels : STOCK,TOW,STREET, & PERFORMANCE.
Before TV# 6.4.47 the 4 power levels had different names: I think it was STOCK, MILD, WILD & HOT but I'm not 100% sure of that. It doesn't really matter, they only changed the names, nothing else.

If you are running the "EASY" tune then the tuning will have the factory deviation %. But if you are running the "MILD" or "HD300" then the tuning will have the increased deviation %

The Loss of cruise control happens because the DTC has been set. The can of marbles sound may be "Diesel combustion rattle" due to incorrect fuel pressure.

Just got back from a weeks trip, and the lack of 'Cruise control' was constant. I was having to delete the 'check engine light', often, so this is something I need to rectify soon. I'm unsure if taking it to Ford, and having them flash the ECM will take out my Mini Max programming?
I'm unsure if there is a 'test' to check whether it may possibly be the sensor, electrical possibly (heard it could be wiring within the valve cover?) or if an upgraded MM programmer would be helpful?
I have the 'stock-Mild-Wild-Hot' settings, and have never been upgraded to HD300. So, I'll assume I have the Mild tunes?

Any specific recommendations here in B.C. for those in need of honesty in getting service with such issues?

Thanks again!

Once you have confirmed your TV# & you are not on the "EASY" tuning, then you will know if there is anything you can do related to the tuner, i.e. update, change tuning. As I said previously as long as your tuner version is above 6.4.32. & you are using either the mild or HD300 tuning then the allowable deviation of those parameters has been increased. The Ford update won't make a difference, Even if the Factory update changed those parameters to a higher value than the H&S settings, the H&S tuning, once reloaded to the truck would change the programming to the H&S settings mentioned above.
A shop with the right diagnostic program can watch the commanded fuel pressure versus the actual pressure and tell pretty quick whats going on with the pump. It will usually be a faulty PCV (pressure control valve) or VCV (volume control valve), a problem with the wiring harness to the pump, or the pump itself has seen some water & the high pressure pistons in the pump are failing. This would be the worst case scenario as it usually sends metal from the pump thru the whole system.

I have only dealt with BC Diesel & BD performance for parts, but I have heard positive comments about all of the above.

Powerstroke2000,
Did you find an answer?

TD-5
Thank you for all that info.

Thanks.

I also recently bought a F350 with a Mini Maxx installed...I did get the manual for the Mini Maxx...did you ever get this resolved? If not I can look it up in the manual.

 

[Gute16]

Hey, got an 09 F350. Had the same problem last week. Once you've updated your Tune Version(you can find the files on dieseltunerpros.com, couldn't include the url as im on a work computer lol) make sure to update the firmware on the Mini Maxx. You do this by scrolling all the way to the bottom of the options menu and youll see the option there, this is once you've plugged it back into your truck. once done, you can install the new update no problem! It will ask you for the DPF delete info and give you all the options to set your truck up exactly how you want it. If you have any other questions PM me.

Yes put your same tune back in it and and more fuel to it mine just done this to me then give it a try and see what happens it worked out for mine
