Any interest for a MAFterburner GB?

dropdfocus · Feb 11, 2003

Well, I'm still interested either way... I like the Stage 2 for the Nitrous switch. And this seems like a cheaper way for me to go turbo and adjust fuel compensation too!

you'll still need a bigger maf, a way to pull timing, and a chip to correct load scales

you can do the a/f, timing, load scales, all with a chip...why bother with a maf burner, then an msd box for timing, and then a chip for the rest? when you can just do a chip and take car of everything?

Off the topic of the group buy, TRUenemy00, but how is the Focus tuned to max when my car stutters and shakes and leans out throughout the entire RPM range. This even happens on my friend's SVTF.

If it stutters and shakes, thats omst likely not a/f related

and you car leans out? so you think richening it up is going to make more power? are you kidding?
There isn't anything you can do with the a/f on a mostly stock car to get any power but hey, waste your money

diablo advance timing to hell and lean it out, on the dyno 0-3whp and has been shown to sometimes ping because of hw aggressive it is
superchips has a less aggressive program 0-2whp
Tom/Mike chip on a fairly stock car, 3-4horsepower

and all that is messing with fuel and timing

but you think by adding/taking away fuel with this maf burner you going to get 15, keep dreaming

why not make a package deal and include an electric turbo and intake resistor and get another 45horsepower

I'm not saying the maf burner is useless or anyhting like that biut to say your going to gain any power let alone 15 horsepower on a stockish car is COMPLETE BULL****<hr /></blockquote>

well said!

I'd still like to see the proof of the 6whp and 6lbs of torque on a stock focus with this thing...

or will he just edit his post again?

And Erik...I agree with you...but it's not the first time he talks out of his ass without knowing whathe is talking about. Always fast at yappin'

OH - And Matt...remember you have to get this GB approved by staff, if it takes place. Otherwise it'll get locked...just a heads up

Tru, I have the Diablo Sport chip in my car, but didn't know what all it could control. So I shouldn't even worry about the MAFterburner? McNew's will reburn it for me as needed...

I guarentee that the stock SVTF does run REALLY lean in stock form. At our last dyno day, some cars even hit 10:1 at certain points.

TRUenemy00 · Feb 11, 2003

if your all motor and not in need of upgrading the injectors (no serious headpackage or anything) then I wouldn't worry about a thing

if you go FI your going to have to get something other than a diabo or superchip unless you have someone do a custom diablo burn on a black diablo chip

but for now, if your not making around 160whp, I wouldn't worry about it

Well, I see I have no fans here.

If anyone is still interested in the GB after all of this, please e-mail or U2U me. Thanks.

its nothing personal

just stating the facts

Erik, don't mean you bud.

I guess that would be your own fault...

TRUenemy00 · Feb 11, 2003

no, really i want to make something clear i may not have.....

this mafburner could quite possibly really benefit some on the jet...just not bone stock cars...more like the heavily modded alll motor cars

imported_focus_rs · Feb 11, 2003

That sounds good to me. Thanks Russell. So you are satisfied with your MAFterburner? Also, if you're not getting NOS, then there's no reason for anyone to buy the Stage II version, correct?

TRUenemy00 · Feb 11, 2003

Here is some info for your reading pleasure:

Mike chip guy said:
It would appear to me that this unit taps into an rpm and TP signal to allow finer control of the MAF signal. It will increase or decrease the MAF signal on a map of rpm vs. TP. This is how the UniChip controls fuel as well. Several problems w/ this. It will not correct for injector size change. It will always be subject to the adaptive control system which can undo changes the that you make. Read Section 9 in the FAQ's.

In order to get it to work well you would have to use an OBDII scan tool to be sure that the fuel trims are minimized at low load and rpm so your high load high rpm settings are not trimmed away.

It cannot get around your speed or rev limiters and has no timing control, its just a glorified MAF adjuster.

And TurboTom had this to say:

even if you go the mafterburner you will still be changing the load to rpm and adding timing as well as moving MUCH closer to your 5 volt limit on the mass air

So basically, if you want to spend $350 for an item and still need a custom chip and have to spend another $250-$400 instead of just buying a chip for $250-400 that will take care of everything, go for it

If you making enough power to need this, your most likely coming very very close to hitting 5v on the maf if your aren't already...so thjat means you need a bigger maf, if you get a bigger maf you'll need something to pull timing because it will be an issue

just to clear things up...this mafburner can calibrate a maf to run with different size injectors BUT that is not the reason people go with a bigger maf when changing injectors, its so you don't hit 5v cutoff

I got the Mafterburner Plus/Stage 2 just so i don't kick myself in the but if i decide to get nitrous in the future, its the buyer choice on that one. I have the Mafterburner and I also have a chip. I will also be getting a new MAF soon too. The mafterburner is no different then some honda ricer getting an APEXI SAFC for there car. I don't see why people are attaking it. Maybe it doesn't have a cool little ricer looking control box that gets in the way. But it can be hooked up to a laptop and it has a datalogging software.

I'm making 150 hp, and running a 14.6 in the quarter and my MAF voltage only goes up to 4.5 or .6 I can't remember. I still have the stock MAF.

Bottom line is, if you have the money to spend then buy it. It could prove to be very benefical. But don't expect to see massive gains out of a stock engine.

Here is a link to a dyno on a focus that has only exhuast and a UDP on it.

Russell · Feb 12, 2003

Directly off the website:

MAFterburner™ is a system which allows the owner to tune his/her air-fuel ratio in 400 RPM increments from idle to redline. This allows the owner to optimize the air fuel ratio for best power throughout the operating range of the engine using a laptop computer. There are two separate tables to allow the tuning in both open loop (wide open throttle) and closed loop (part throttle cruise) situations. The software is user friendly and allows the operator to make quick adjustments in real time, while driving or on a chassis dyno.

The MAFterburner™ allows the user to fine tune his/her car and accommodate larger injectors, aftermarket mass air meters, and many other part modifications.

The MAFterburner™ is programmed via a serial-connection to any host laptop or desktop computer running at least Windows 98. The graphical tuning utility suite, called MAFCOMM™, is incredibly flexible and easy to use. This software facilitates the user in programming air/fuel changes in 1% increments over 400rpm intervals from idle to redline (400-10,000rpm) in both WOT and idle or part-throttle cruise conditions. Once the tuning is complete, the host computer is disconnected, and the MAFterburner™ runs "stand-alone" in conjuction with the PCM.

This device monitors engine speed via the PCM's coil-driver outputs, throttle position sensor (TPS) voltage, and the mass-air flow sensor voltage (MAF). At a speed of over twenty times per second, the on-board signal processor samples these signals, reads a target air/fuel correction from one of the user-programmable data tables, calculates a new target air/fuel ratio and outputs the "corrected" MAF signal to the PCM.

The MAFterburner™ has the capability to accurately read engine speed regardless of ignition system type. In fact, the internal speed sensing electronics have been thoroughly tested on Ford "Waste Spark", Coil-on-Plug, and 4/6/8 cylinder EDIS style ignition systems.

The MAFterburner™ has "Real-time" data logging capabilities as well as the ability to export/import the air/fuel correction maps to/from a file.

STAGE1: Single-bank of air/fuel maps. This device has two tables, Open-loop 1 (OL1) and Closed-loop 1 (CL1). The MAFterburner™ can switch back and forth between tables based on a fully-programmable wide-open throttle breakpoint voltage. This allows for different air/fuel maps for both WOT and part-throttle driving conditions.

STAGE2: Dual-bank air/fuel maps. This device has two banks of two tables (4 total). They are Open-loop 1 (OL1), Closed-loop 1 (CL1), Open-loop 2 (OL2), and Closed-loop 2 (CL2). The MAFterburner™ automatically switches back and forth between open-loop and closed-loop tables, within a specified bank, based on a fully-programmable wide-open throttle breakpoint voltage.

The user can switch banks "on-the-fly" using an external toggle/rocker/blade type switch. The STAGE2 kit comes with the bank select harness but no switch is included. This allows the user to select the switch that best matches their interior motif and helps keep the cost of the kit down.

The MAFterburner™ STAGE2 (PLUS for SHM brand) device also has a built-in RPM "window" switch and WOT switch to be used for intelligent and safe nitrous kit control. This output switch has the capability to sink 0.25A of continuous current. It is protected against inductive kick-back and can therefore directly drive most standard 30A automotive relays.

You tell me what chip could display it on a screen and allow you to adjust it for under $400? There are so many benefits, and i ask that people stop knocking on the Mafterburner untill they see it in action. I beleive that the money i spent on it was well worth it.

Yes if you install bigger injectors you may need a chip, but you do not need a MAF calibrated for the injectors.

Go look at the price of a RPM window switch for a nitrous system, and tell me how much it cost....... I found one on the NOPI web site made by NOS for $199. If you bought the Mafterburner stage 2 it has RPM activated window switch. So lets total that up, $199 for a RPM window switch and $189 for a new MAF. You have now bought the mafterburner stage 2 with just those two items.

Now, if you are using the stock MAF and it is pegged out then you need a new MAF anyways. The Mafterburner can benefit alot of people on here.

I just read that the mafterburner is now adjustable in 40rpm intervsls now. It also has a built in calculator to help you determine what adjustments to make to get your A/F where you want it.

That is about the most info i can give right now......Russell

Any interest for a MAFterburner GB?
