I can pick up either for around the same price and was curious to see what people thought of each.

1. Greddy eManage Blue w/support tool

2. VAFCII

Why would you choose one over the other.

Thanks!

 

Is this a philosophical question? I'm not that familiar with 6th gens, but I don't see much point or value in getting either system. What are you hoping to do with them?

 

You do know what the systems do right?

I'd rather get the e-manage ultimate cause if your going to spend money on the blue might as well spend the extra and get the better of the two. If you don't want to spend that much then get the VAFCII

 

I picked up an emanage blue w/support tool for a $160 so a VAFCII really wouldn't be cheaper and a EMU would be ALOT more. Also I don't see what the big deal about the ultimate is. I can adjust fuel, timing, and injectors with the emanage blue.

I take it you would go with the emanage over the VAFCII for the same price.

 

Bake a cake

 

Neither, they are both a colossal waste of $...................

 

so what would you suggest for tuning?

 

If your suggestion is one of the following please stay out of this post.

1: Why do need them

2: They are a waste of money

3: Anything else that doesn't revolve around which one you like and why.

Thanks

 

If you cannot afford a true "stand alone,” and its setup and associated tuning costs (read hours of dyno time to develop all of the environmental curves), don't bother. Too many have tried these things only to find (1) The "max" output is only achieved under one set of environmental factors (temp, altitude, humidity, etc), and as soon as the environment changes, so does HP(usually downward), Torque (also downward), and sometimes even drivability; and (2) These things can lead to ECM death...........

 

Oh, I see; if you totally disagree with the premise of the thread; no matter how off base it may be, you are cordially invited to butt out. Right.................no evidence of “only the news that fits, we print” here…………….in that case, go right ahead and do whatever you want, regardless of what experience anyone else might have on the subject…………………

 

I cannot think of anyone using a stand alone on any motor maxima. I used a VAFC2 with good success after my a/f was rich after headers. The only differences in my dyno number with relevance to enviromental factors were I made more power uncorrected in cooler weather and less power after the motor was heat soaked. I spent $220 for a new vafc and picked up about 10whp and the same torque with simple manipulations to the maf. I would see the stand alone being absolutely overkill for an all motor maxima unless we are talking about some insane setup.

 

I think the thousands of people using piggy-back systems would disagree and your experience has nothing to do with it. You have been answering a question I didn't ask which has no place in this thread, plain and simple. If you have an opinion on which system to use I will listen. If you have an opinion on why neither is good I don't care.

 

I agree.

So which would you pick, eManage or VAFCII?

 

I'll try to keep that in mind the next time a flat bed pulls up in front of my shop with yet another dead Nissan on it, equipped with a piggy-back unit........

 

I had a good experience with the vafc2 so I would choose it. I plan to reinstall it in my g35 before too long. One point that JFP in PA brings out is simply a reminder that the user should not attempt an install or modifying fuel points unless they understand the process. I am not suggesting that you would do this but I am sure it has and will continue to be done. If you were going to get an AFC, were you planning on picking up a wideband to tune it yourself or take it a dyno shop and them hook up their wideband?

 

I'll be using cipher for datalogging purposes. No reason to add a wideband when I can utilize the two it came with.

 

I guess I should have realized the 6th gen came with them since mine has the same. I looked at the cipher but decided to go with the autoenginuity with the enhanced nissan properties.

 

How's that work for you. I've heard some people say it won't log quick enough for O2, throttle, rpm. How hard do you find it to calculate AFR of the voltage read outs?

 

i picked up a sfacII b/c im under the impression that im running rich with an intake and a cat back, a friend of mine saw some decent gains and im looking to make up for some extra weight (sound deadning and system). im under the impression that the sfac will help me attaine the a/f ratio im looking for. im also looking to get on the bottle in the summer and i like the extra maps i can navagate through with only a touch of a button.

 

You posted this in the wrong section.

For informative and educated responses, have someone with the right authority move this thread where it belongs, in the AM foum.


Why?

 

Thanks for your input NmexMAX. You quite frequently help me out. Maybe I'll just start a new post. The more I look into it the less the emanage seems to work for what I want. Most people are saying it won't adjust timing like it says it will so I don't get the point of it.

 

It will adjust timing, thanks to DandyMax.

All those revolve around the eManage Ultimate. I'm using the eManage Blue. I think I'll put in a call to greddy today and see what they say.
