LLY/LBZ MAF differences

[MMLMM]

LBZ intake in LLY, this has worked great for the trucks I have done
Grams per second (not lbs/minute)

Mike, that's identical to the table I posted earlier, just in g/s instead of #/min. Just FYI.

lol, durr.

oops, maybe if you'd switch to metric system

 

[Redbowties88]

Thanks guys. Well it's not a stock lbz intake I'll be using here but a banks for an lbz. But it should be the same as the design it to well, work

Hey, I think we should!! It just makes more sense!

 

[05' Ditry Duramax]

Well, the LBZ & LLY tables aren't identical, just similar, so no, you couldn't just copy them. If your LLY has the "flat" airbox, no change needed. If you have the 06+ airbox, but haven't changed the tables, you probably should. Even if you're not setting codes, it might not be running to potential...

I see what your saying now. I still have the K&N filter on there. I might try and rescale it and see what happens. Thanks for the info.

 

[Redbowties88]

if what you have seals well dont worry about it. the way my banks is there is no way to make the LLY version work properly

 

[Diesel Pilot]

Here is what I have found and it won't help you at all.

The truck will tell you what it wants. I've had LLY's (mine and a few others) not need the conversion in the tuning at all. My truck has never thrown a MAF code with what ever tuning I put on it and it runs great with the hybrid LLY/LBZ intake(s) I have used on it (multiple setups).

Now, there are a few other LLY's that have been a real PITA to tune for with LBZ setups. I mean not throwing codes for a while, then all the sudden won't run right PITA.

I think it might have something to do with operating system or the difference between 04.5 and true 05's, some 05's don't have a problem. IDK. I'm happy my truck is easy and I don't have to fuss with it.

You'll just have to see and the advice that the other guys have given is top notch and I would definitely try those things first if your truck doesn't like the LBZ setup.

 

[Redbowties88]

Can't answer your question, but I can tell you banks will sell you an LBZ intake tube. I called to order one for a friend who was using the LLY tube and they said they would sell it to me.

Per their email....

The only difference between all of the current Ram Air kits for the Duramax is the Intake tube. The Intake Tube for the LBZ Ram Air intake is part number 42152 and retails for $59.59. You can order that part through our Customer Service department at 888-839-5600 or Tech Support at 888-839-2700.

well unfortunately that quote is a load of shit. i would expect nothing less from the people at banks. it doesn't fit onto the lly airbox lid the coupling is too small.....so now i guess ill call them tomorrow and see if either A. i can get the LBZ airboz lid and if it will fit or B. send it back for a refund, eat the shipping both ways, and still have a shotty connection there.


life is good

 

[Redbowties88]

well i managed to man handle it all together. not a great fit but much better then before. MAF is ll wacked out even with the updated table...so im working on my own table now to hopefully make it work

 

[Redbowties88]

ok well im still getting a DTC....but only the 102 code not the 101 anymore...

MAF reads somewhat normal. i regret not logging more with the original setup. but just by going off what i remember off the top of my head it seems about correct. it trips the code at idle even though i programmed it to never read lower then 5 lbs/m. so far here what my table looks like. appears to be driving normal

should i just set the code to not report as it does it at idle and i dont think there's anything else i can do for it?

Set all fields in "B0806" to 65000

and set:

C0901 = -3
C0902 = -3
C0903 = 65000

 

[Redbowties88]

EDIT: looked at the wrong table i see where your coming from...

but just setting that code to not report should accomplish the same thing slightly easier right?

No. setting parameters to a certain value changes there operation.

Setting a code to "not report" just covers an issue.

People, simply turning a code off is not a good idea. If you are getting a code there is a issue, and 99% of the time you can adjust the tune so you dont set a code. Setting a code to "not report" does not require EFI Live, you can stick a piece of black tape over your check engine light much cheaper.

yea but its the same thing in less action. making the counter go to 65000 before the code triggers is just like turning it off. the errors are still there it just takes an insane amount of them to set the code. if there was a real problem you would still never know.

i tried fixing it with the flow table as that would be ideal but this intake is just too wacked out to correct. its almost like a bubble where the MAF sits. real fat and skinny before and after. so the air going over it must be going really slow

 

[MMLMM]

sounds like you have it figured out then.

 

[Redbowties88]

well im not trying to be a dick or anything just saying.... is there some difference i dont understand?


i see what your saying for most situations and i agree. but for this one setting the error count to max and setting it to not report at all seem to be the same thing to me

Im not saying your coming off like one lol.

Forget the codes and the test enablers, fix the tables. Logging what the truck is actually doing will be a huge help.

yea ive been logging...well not logging more like watching and not recording. maf is all over the place at idle +/- 5 lbs/m smooths out when your driving though..
