MAF problems - Page 2

Proof is in the puddin, the stock maf on a stock tune peggs at 5v(1000) it has a lil more with a custom tune but not much.
This is at WOT on a stock blower and a 5# lower, yes a five pound not a six.

MafV is the PID of concern.

To be honest with you this isnt the first time Ive heard of JDM saying this. No Im not bashing.

And to be honest, Rick told me the same thing. But its MY shit so I believe what MY shit says.

I work on thursdays and my hours are 2 to 10. kind of makes it hard to do anything. I am thankfull for you guys trying to help. I dont want to hurt my motor and Ill do what i need to so that doesnt happen.They did say something about there tune does something to compensate for cold air.

If your not happy with what your tuner tell you no matter who they are you should find a new one.

The customer is always right. If you want something and they tell you NO go somewhere else. Or you could ask them in writing "if my shit blows will you give me a brand new JDM built long block to cover my losses?"

wade w · 09-18-2007, 12:12 AM

Im going to do what i have to. call some one else. call them back and talk to another person. what ever. while Im thinking about it. Youre truck looked real good with that new suspension set up Chris. Congrats

Mike · 09-18-2007, 12:12 AM

Chris,

Where did Wade say he wasn't happy with what they said? Are you trying to put words in his mouth?

Mike · 09-18-2007, 12:19 AM

Chris,

Wade,

If JDM thought that you were even close to needing a MAF, I'm sure they would be more than happy to sell you one.

Do you have access to a Laptop?

wade w · 09-18-2007, 12:32 AM

yea. thats what im on now.

Mike · 09-18-2007, 12:34 AM

Do you have the SCT Live Link software loaded on it yet?

wade w · 09-18-2007, 12:39 AM

I dont think so because I dont know what that is.

Mike · 09-18-2007, 12:42 AM

You can go to www.SCTflash.com and download it. You will also need a USB cable. You will have everything you need to see what your MAF voltage looks like.

If you have any questions, just ask, both Chris and myself have used Live Link.

wade w · 09-18-2007, 12:59 AM

Thanks Mike

Wade are you running a JDM Tune? I think you said you were if so I would get the plugs down to .030 to.032 4177 tr6 is the stock lightning plug and I would order a 2400 SCT and jdm will set the tune. We were going to go to the 2600, 2800 or even the 3000 but Jim SR. said they bog off the line and do crazy things through the run and as he said there is a lot of tuner's going to big on the MAF As he explained to us it makes less power because you can't control it and keep it stable. Also JDM has used the 2400 and made over 900 HP at the rear wheels that is 1158HP at the motor Don't think you are going to see that yet. We only have 2400 on Daryls and Bill and the reason is not because we didn't try They would not sell it to us because it's not tuneable.NOTE IT IS TUNEABLE FOR WIDE OPEN THROTTLE RACE ONLY!! They do it daily I just asked today about the C116 tune and thats a lot of power and they said stay with the 2400 and they would do the rest. Mitch P.S. NO WARS ON THIS JUST QUOTING WHAT I WAS TOLD IN NEW JERSERY The Stock Maf flows 1023 CFM. Easy Fix 2400 and re tune and u are safe, Air flow wise. Still need like Mike said a good sorse of Imformation we can help

Whaler · 09-18-2007, 07:09 AM

Wade, every truck is different. Mike logged mine for me with a non-ported blower and a 6lb lower and it was not maxxing out. Randy's maxxed with a smaller pulley, so... check it and see.

chrisheltra · 09-18-2007, 07:25 AM

Wade,

Find out what parameters JDM wants you to datalog and next time you plan on coming up here to go to the track give me or Mike a heads up. One of us can bring our laptops and show you how to datalog.

Mike,

You dont happen to know what parameters JDM want there customer to datalog do you?

60', E.T. & MPH is all the data they really need

Seriously though I haven't ever asked them, but right now if we want to rule out the MAF we only need RPM & MAF_V.

any sugestions. will it need a new tune.

After re-reading your original post it got me thinking, and someone correct me if I'm wrong please.

You said that you think that your MAF is starting to peg after you streched the trucks legs out. I would think at that high of a load if you were to peg the MAF you would be part of the vented block club. Also you said it did that directly after a plug change. That would lead me tho think that could be the culprit.

That makes me think that Larry was on the right track originally. But it still wouldnt hurt to datalog your MAF counts.

wade w · 09-18-2007, 11:50 AM

yea after reading all of this. I think its the plugs. I changed the filter last night but I didnt have time to get to the plugs. when I went home it done the same thing ecept it stayed. its still missing. I think it fouled one of the plugs. I still want to data log it just to see were Im at. thanks a lot everybody.
