I Need Help, Please.

I bought the 10n1 from someone here. The truck starts up and idles smoother than without it. The Security feature works as advertised. I can toggle through all of the settings with no problem. However, it feels like it is stuck in Valey mode. The boost comes up slow and the motor dies at 4,000rpm give or take a few hundred. It is a keyed version without the two buttons. Is there a fix, or is the unit just defective? Guys, I"m sitting here stranded. Help me out. :squint:

Re: I Need Help, Please.

did you reset the fuel pressure, install the 3 bar map, is it set for your injectors? have you talked with todd A yet?

Re: I Need Help, Please.

It is the 10n1. It is for the stock Inj. The fuel press. should not be a factor for this chip, unless I just run out of fuel. At least so I am led to beleive. I've tried to get in touch with Todd, but all I have is his email, and so far I've heard nothing, all though be it I just sent him an email a few hours ago. It does not use a 3bar map as well.

Check engine light is not on, only when key is in on position with motor not running. Nor does it blink.

Re: I Need Help, Please.

Thanks, let me give you my situation. I've not changed the AFPR, or the fuel pump. Matter of fact, the truck is stock save for a brand new ignition system including Distributor. Ok, with that. On the stock chip it runs great. Four 9.0's at the track. Now, with the 10n1 chip, in T1-16, or any setting for that matter, at 3,800rpm registered on Tach, it stutters really violently, then picks up to about 4,300rpm and does it again. Further, when I flog it, it hesitates just a little as if it wasn't getting enough fuel, or to much. Now, if I just hold it in second gear, at half throttle, and only say 5psi, let it cruise up to 3,800rpm, it still does the same thing. So I just don't see how it is a fuel issue. I've pulled the MEMCAL out, swapped it for another, turned it around(it then didn't run hardly), and I just happened to have a 3 bar Map laying around from my S/C Dakota, and so I put that on, and no difference. What else is there for me to do, especially based on the part throttle dieing of the motor at 3,800rpm? Am I just shit out of luck?

From what you described it sounds like your not getting fuel... have you confirmed your fp is correct? have you confirmed that fp raises 1lb per psi of boost? Do you have the correct map sensor? when switching maps did you pull the ecm b fuse for little? Have you changed your fuel filter? do you get check engine lights when this hesitation presents itself? do you have datamaster? if so any error codes or sudden changes?

also if the truck runs good on the stock chip but total crap on another chip then that would have me thinking about whether or not somethings not right iwth that chip or possibly your not meeting the required modifications needed to properly run the more agressive tune of that chip. I'd see if you could meet up with someone who has the same chip.. spend the half hour, swap it in and try your truck out.. that will tell you if it's the chip or not.. if it's the chip either try doing the suggested or required mods for the chip or send it back to Todd A to have it looked over

More boost! N.A.S.T.E
Re: I Need Help, Please.

as it is right now he has no AFPR , fuel pressure gauge, and a 2 bar MAP. you need to make these changes for it to run right am i correct here???

Landry when i spoke to you on the phone when i was at work i told you it needs a 3 bar MAP AFPR and thats when i asked if you had a fuel pressure gauge and you replied no. I told you you need to order one. i dont want bad blood here the chip was fine 3 weeks ago when removed from my truck

Further, when I flog it, it hesitates just a little as if it wasn't getting enough fuel,

you need to raise your fuel pressure

Thing is, the fuel pressure I don't believe to be the issue, because if I just pull the truck into 2nd gear, and just give it enough gas to get to 3,800 rpm, through normal or even lighter than normal accelleration, the truck dies like spark is being taken away, not fuel. It is a complete and total kill. It is supposed to be a 10n1, which then does not require a 3bar, but the seller is saying it does. That doesn't seem to add up from what the maker and seller are saying, however, I'm not disagreeing considering it could have been remaped. I dont' know. I'll be putting in the 3 bar tomorrow. I ordered one today. I thought I had one, but it was only a 2 bar. But even still, I'm not boosting at 3,800rpm when I'm just easing the truck to that rpm and it still dies 100%.

Re: I Need Help, Please.

I understand what you are saying, but understand I'm not new to world of boost. My last ride was a S/C Dakota 408 stroker with a FAST stand alone. TheFastman.com I'm very familiar with how the systems work. The truck dies at 3,800rpm and with me just giving it enough gas to crepe to 3,800 rpm, I don't believe it to be fuel related. Because, I'm not running with bosst, I just ease her up to 3,800rpm. It dies 100%. (that seems more like spark being removed or fuel injectors being shut down) The 10n1 does not use a 3 bar. Yet you insist that it does, why? Again, I ask you, is it, or is it not a 10n1?? The Ultimate needs the 3bar, not the 10n1. All those items you said I don't have, I do. They are going on today. However, even if I raise my fuel press to 50psi, I don't think it is going to fix the complete dieing of the truck at 3,800rpm when not even under boost.

Re: I Need Help, Please.

You need to look at the programs on it. There is no telling what is actually on the chipset. It is pretty routine for guys to reprogram the chips for different cams and whatnot. You might want to see if you can pull the bins or better yet, just tell someone like the Canadians (Nolan) and see if they can just set you up with a bin that closely suits your needs.

If your truck runs fine on the stock chip and then runs like crap on the 10/n/1, you've probably got a worked over chip.

Run a datamaster on it. If you don't have datamaster, put the stock chip back in until you get a chance to run datamaster. Guys USED to do this all the time. Do NOT Put in a chip and try to fix the truck to it. The chip is supposed to be adjusted to the truck. Put your stock chip in. Run datamaster. Make sure everything is running correctly first.

10-n-1's were available with 3 bar, but if you ran a 3 bar program with a 2 bar sensor, they would still run, not die like what your experiencing. The chip may be set up for 50 pound injectors, etc. No telling. For all the trouble your having, you probably should've just bought a new one.

Re: I Need Help, Please.

I agree. I wish I had bought a new now. At least then it would be no problem getting it replaced. The only thing the guy that sold it me can do is refund my money, and I'm sure he isn't excited about doing that. These things, from what I understand, are supposed to be plug and play. Ie, if you run the stock settings, T1-15 it should run just like it was never changed. But it does not. I agree, if you start trying to run 16-17.5 psi, fuel becomes and issue, but I am not doing that. I mean, for the truck to run 4 back to back 9.0's with 1.9 60' times, I'd say it is running quite well for stock. Now that I am sort of stuck, is there anything that can be done to the chip short of nothing to get it back to where it should be, ie the original programs??

Re: I Need Help, Please.

From the looks of it, I'm going to be in the market for a new chip. I'm really bumbed out that this chip isn't working. Lesson learned. Don't buy used Electronics, and sure not to go wrong, when things do go wrong. Add a hundred dollars and I could have had a brand new Ultimate. Man am I dumb.

Re: I Need Help, Please.

usually when you try to hit boost over 14.7psi you will need a 3bar map so the computer can adjust timing, fuel , and spark accordingly. a stock 2bar map sensor will not work with wanted/user dersired boost of over 14.7psi. i would install the recommended map sensor first before you give up to quickly.

Re: I Need Help, Please.

man what a mess... I'd try the 3bar map first alone with the other suggest mods from the seller before bad mouthing him in anyway.. I'd also concider putting a walbro pump in.. ultimates require this I believe and pretty much any other chips do.. infact the factory pump is the same one ran in the n/a 4.3L trucks so it's' barely enough for our boosted trucks anyways..

Also why not try what was stated above and have someon that can read bin's check it out.. possibly hook you up with a tune your looking for.. your mostly stock so it shouldn't be too hard for one of the tuning gurus to hook you up with a chip.

Re: I Need Help, Please.

The ECM can handle boost levels over 14.7, up to 17.5. That is why the 10n1 was created. For tight wads. What the ECM will not do is adjust fuel or timing after 14.7. After 17.5, as Todd explained it, the ECM then goes a little wacky. I'm not giving up so quickly. I'm picking a 3 bar up tomorrow, but the 3 bar isn't going to change the fact that at 0-5psi at 3,800rpm, the truck dies. But who knows, maybe I'm wrong, and if I am, I've got alot of ass to kiss. I'd do it gladly however, Trust me, I want the darn thing to work.

it can handle the boost levels, but your stock 2 bar map sensor can't read beyond that, that's why you need a 3 bar map sensor.
a 3 bar map sensor has different tabels than a 2 bar map. this is causing problems.
get back to the stock chip, get all the parts for the ultimate, including new chip and start all over.
and buy a scantool
