I am in the market for a tuning devise but i cannot decide which one to go with. I would like to buy a used vafc I, because it would be cheap. I heard after two weeks or so our ECU's override it or correct the changes from the VAFC's ... has anyone had experience with this?


any insight would be greatly appreciated.

interesting, I have a Neo and would also like to know this. I will be getting E-Manage though to replace the Neo

E-manage Ultimate works great and is a great one to use if going custom turbo. Basic E-manage I don't think will work. NEO 2 works fine if you're staying NA, but I'd wait until you have all the bolt ons to see it's full potential. VAFC 1 and 2 from what I heard is crap and the ECU overrides them.

ya sorry, i have i/h/TBspacer/comptech mufflers/ and planning on getting UR UD crank pulley installed wed or thursday... So with that in mind I should go with the neo?

If you dont plan on going with n20 or super charger then yes the neo is the best way to go.
I only have headers, intake, and underdrive crank pulley and went from 220whp to 237whp. Thats 17 whp just from a dyno tune with the neo. But do not go cheap on the shop tuning your car, get the best in the biz when it comes to dyno tuning. And ask what kind of dyno they are running, only trust dyno jet brand.

If you are thinking about n20 check this AEM unit out.

wow 17 hp nice... yea i was thinking of going to Jotech here in dallas, they have a great rep but do alot of turbo applications,

thanks for your help davepaul.... even though you are an Eagles fan

haha freaking cowboys! any time tho

I am sc and I got the ultimate eman, I saw someone said if u r sc u should get the neo or a vfac I will think the the eman is better than both

NEO for N/A

NEO for bolt on NA.

Emanage for extreme NA and FI

extreme NA = internal work for example 3.5 conversion.

I don't think I'd spend the money on any of them with the mods you have. You're gonna see very little come out of it.

davepaul just said he gained 17whp from a tune with the neo...

Check it out

You were making 220WHP with headers, intake, and underdrive crank pulley before the tune? You have an auto?

yea he probally does, my friend with that exact set up on his 6 speed made a little over 20whp than that

Mike made 236WHP in his '01 with just intake and header. I would think that just a tune and no Neo should be able to get you into the 230s without a Neo.

my point is he gained 17whp on a neo tune, which you said i dont have the mods to make the hp that a neo would give.... but i have the exact same mods plus a p2r TB spacer, so to me ~17 whp def seems worthwhile.... do u see my point now?

That is correct, with 18 wheels.

Im helping my friend tune his cl-s with comptech headers, tanabe exhaust and injen intake. He is using my old neo that i got rid of for a standalone. Ive tuned a few turbo rotaries so i dont think that this will be that bad. What kind of air/fuel do you guys tune these for? I was thinking 13.5 wot, going to 13.2 where vtec kicks in and then lean back out a few?

yea thats sounds about right

will this work on our cars?

^ No as you can see from the application list AEM will not work and it won't recognize it. 4 cylinder cls only. I noticed even no V6 accords will work and our engine is basically a beefed up version of the V6 accord engine.

So final verdict, Emanage for 3.5L with boltons? I'm looking now so hopefully I can get more input. And that's regular Emanage not the ultimate right?

P2r told me to get the neo since iam not going F1. Otherwise I would go Emanage Ultimate

is it true the stock computer over rides the VAFC, im asking cause i already have one, but it's not installed.

YEP.. our ECUs are smart. I reset my ECU today and it made a world of difference.

does it over ride the neo settings too?

Are you tuned with anything?

yeah what are u tuned with?

I have a tuned NEO. The ecu will only override the NEOs settings after some time but once you disconnect the battery and reset the ECU the NEOs setting will take effect again because the NEO doesnt lose its programed settings unless you physically reset the unit. My best advice in which I just figured out last week is to reset your ECU BEFORE you get the car tuned so the neo will be tuned on the ECU running the car fine and not with the ECU leaning out the car or running it rich for some reason. If you do that then once the ECU gets to the point where its learned the car again and starts to override the NEO then all you have to do is reset it and then you will get your tune back.

Are you sure that the ECU overrides the NEO? I have heard conflicting things said by different members here on the forum.

yep im sure. You gotta understand how smart these ECUs are. They will fight for what they want and a simple piggy back like a NEO will not make a perminate change.

So how do you know when you need to reset it?

this is when knowing your cars daily performance capibilities come in handy. Once you feel like the car aint pulling how it used to after u got it tuned... then yea the ECU is back. More than likely the ECU will fight it in under 2 weeks.

I was told that the AEM FIC will work for our cars.

You have to reset it every 2 weeks....?

More like in less than a week, but I really dont bother reseting it unless I know im going to be doing some racing shortly afterwards...

hello to all.i need some help,what ecu upgrade could i use (neo/e-man) one that the ecu does> not override. and i could use in with bolt ons,or stock trim.

2001 cl-s

I just ordered my emanage blue and would be pretty irritated if I had to reset my ECU every couple of weeks just to get peak performance out of it. Does anyone know? I know CLS6SpeedNupe is correct about smart ECUs b/c my car now needs to be reset every couple of weeks b/c of my mods. It starts running super sluggish and the easiest sign is weird shifting. Once I reset it, all is well.

Or when it gets really bad, you'll throw a CEL of P0128. Coolant Temp Below Thermostat Regulating
