4.4 DC on the highway?
Thats super low.


Oh, your talking pulse width.
I dont think I ever see over 3. been a while since I looked.

What do you see for DC on the highway and at idle?

 

Idle about 13 DC and highway about twenty to thirty unless I really get into it.

 

Absolutely Glenn. It doesn't hurt to ask for more.

Thank you for the kind works, 95schauf.

William, nice avatar. Have you ever spoke to that guy? He's actually a pretty nice guy.

 

Not to be ot but nice and knowledgeable is two different things. He seems like a good guy and it's good he wants to help people but needs to fact check a few methods and such.

 

Its one of mad vans old avatars. I have it in honor of him.

One of those running forum jokes around here though that you don't know. =)

 

Great tribute.

 

Something is definitely off here if your smoking out the highway... Was those number from your tow tune or your extreme tune? I don't think we're too worried about smoke in your extreme tune, but more so your tow tune right? Or is it all the tunes that you want to smoke less?

My hot tune maxes out at 3 ms of PW and I can drive it around anywhere I want without smoking out the highway. Even towed in that tune before with minimal smoke. My tow tune maxes at 1.7ms and is pretty much completely smoke free...

The only thing I can figure is that your getting in the throttle pretty hard before the turbo spools and the tuner is bringing quite a bit of fuel down low to get the turbo going. Or you have larger than 130cc injectors in there... Possibly larger nozzles. Tough to say without sending them out. Heck, maybe the tuner just needs to call for less pulse width and bring it in slower..

You can pull out some pulse width in no-low boost situations and have them raise the pulse width back up when the boost comes in. That's how a couple of my tunes are. PW stays pretty low and as RPMs and boost rise, PW rises, so fuel comes on slowly as boost rises to keep smoke down. Obviously there is less power in low boost situations this way than just throwing the fuel at it would provide, but it's the only way to keep from smoking out the highway. IIRC you actually had Tony do this for you, but you weren't happy with the power? My "daily" tune is like this. @ WOT it will max out at 2.0ms of pulse width with no boost, but as boost rises more, pulse width rises. Ends up a max of 2.8ms at WOT and full boost. It will smoke if you are trying to make it smoke, but if you drive it normally, it won't

 

They were from my heavy tow tune and your right about smoke in my tow tune. That's tough one Travis, I guess I want my cake and eat it too. I don't want to lose power but I want less smoke. Tony did turn it down for me once but I had less power and less smoke.

I maxed out at 4.4 ms of PW in my heavey tow mode. The only thing I can think of is that I'm at to low of RPM's when it smokes the worst. That's one advantage of a stick. You have to remember that I'm talking about Tony's tunes now. The first go around with Beans didn't work out at all. In that tow mode I could leave my foot on the floor, not have to worry about EGT's but did not have enough power to keep my 5er rolling. Tony's power is great but smokes alot and **** poor mileage. In fact I use light tow mode with Tony's because heavy tow mode smokes more. I flew through the Rocky Mountains on low tow mode.

Yes, your probably right about mine needing less PW down low, makes sense to me. The turner is thinking that I have the 130cc's so the tuner is calling for more PW down low and because I have larger injectors its not necessary thus more smoke. ding-ding

Thanks for this, its making a lot more sense. Tried to rep you but can't.

 

Mine always smokes the most when I don't want it to.

The other day I was following my buddy up a windy steeper road and had to slow down to pass a few bike riders... well when I gave it throttle to make it up the hill it was lugged down and blew out a huge black cloud behind me.

But when I'm gunning it to get on the highway I only get a haze...

 

I bet the bikers were real pleased!

 

Luckily they were spandex wearing bikers and not leather wearing bikers. lol

 

I made some runs in my tow tunes this morning on my way to work.. I see a max of 2.0 ms in one tune, the other maxes out at 1.8ms and it may haze very very slightly at low RPMs with a good load on it, but I have plenty of power to pull anything that I pull and not smoke anyone out. It's tough to compare tunes between stage 2's and something that's supposed to be for 130's with stock nozzles. Point I'm making is in your tow tune your pretty much using every bit of fuel that your 130's can flow if you do indeed have 130s in there.

IIRC stage 1's will empty 130cc of fuel in around 2.5-2.7ms at 3000 psi of ICP. So, I think I'd ask the tuner to pull back PW slightly on one tow tune and leave the other tow tune alone and see which one is better afterwards.

 

The point your making is that my PW is high (3.8 average with my foot on the floor) because the tune is asking for more fuel then my 130cc's can deliver? If the 130's can put out 130cc's of fuel at 2.6 or so then why am I seeing up to 4 PW? I will be the first to admit that this stuff is going right over my head!! Ever hear the saying that you can't teach a old dog new tricks? Is Tony still in business? I really don't want to pull my injectors but it seems to me that its the only way to figure this out. Didn't you run 1's with 2's tuning? Wouldn't this be about the same thing, the tune calling for more then the injectors can deliver? My T500 just arrived one hour ago, I'll see tomorrow what difference that is going to make. Thanks Travis for your patience!

 

Glenn I mailed it to you today they said Sat. or Mon.

 

Alright, thanks. Full report please! LOL
