map ecu 2

[fivebob]

Getting the best fuel economy is a matter of playing around with the injection timing, not all aftermarket ECUs have this ability hence the misconception that power and economy cannot be had in the same map.

i have a map2 in my caldina tuned by steve its awesome and only seven wires to install will be putting one in the next car i build aswel they are so cheap for all the features and you can have them in and running in like 30 mins! i have only good things to say about the map2 and as far as connecting to the laptop goes i think it would probably be something to do with a converter you were running because they are a serial pot connection on the map2 you have to run an adaptor to usb and it is the software for this which crashes but there are plenty of ways around that issue

[steve murch]

people normally bag things due to lack of knowledge and it doesn't matter what ecu you have it ll only give the results based on the person tuning it,the comment above about " tuning for power and economy" both being the same is true.
when any car is tuned correctly both will happen,when you have a well tuned car it ll drive better thus gives better economy due to the fact you don't have to push it as hard.
connection problems with the mapecu can be a problem using usb but can be overcome with a serial card slot.
like any trade,a bad tradesman always blames his tools.

wouldn't touch a map ecu again, but others may disagree.
greedy e-manage ultimate if its a road car with some mods.
standalone if your aim is all out power and economy is no issue

why say that adrain? only cause you couldnt tune yours to suit your needs? or are there other reasons?
emanage doesnt even come close to the map ecu or map ecu II for features etc

I don't quite agree with the Map ECU 2 being better than the Emanage Ultimate. Dont get me wrong, its a very capable ECU but I prefer the Emanage Ultimate for the following reasons:

- Direct control of Injectors
- Direct control of Ignition Timing

The main bonus of the MAPECU is of course MAF Elimination, but the Emanage Ultimate can do that without a problem either. It also has more control over Throttle Tip-In than the MAPECU. Also the MAPECU achieves its Fuel Adjustments much like a SAFC, it intercepts the Signal from the MAF/MAP and modifies that.

Only problem is doing that also modifies Ignition Timing, if your tuning for larger injectors pulling alot of MAF/MAP signal then the timing changes also and that needs to be compensated for. The Emanage controls the Injectors directly, meaning any adjustments are made after the Stock ECU has calculated its Load & Fuel Requirements.

[steve murch]

emanage is also limited to what vehicle it can run and there no more advantage intercepting the injectors over load signal
the map2 does both fuel and ignition so any changes made in fuel aren't a problem,
the map2 also does OBD2 to which many cant,and i runs full 02 control to which is why a certain company in japan uses the map2 for the latest r35 GTR neo spec cause nothing else would allow them to change all the engine mods without the ecu packing a sad( even motec and others couldnt).
so would love to tell but we signed a little bit of paper that we don't want to breach
the map2 also comes with everything you need out of the box and doesnt need adaptors or extra wirng to be brought on top of the purchase price

the map 2 is still topping my list of aftermarket engine management i think after reading this i may get one

This wouldnt be a power enterprise ecu as they look amazing simliar

The Emanage Ultimate isn't limited either? There's a Universal setting which lets you create your own configuration for any vehicle.

I didn't know the MAPECU intercepted the injector & ignition signals. I thought that it only skewed the input data from the MAF/MAP sensor which would affect timing because it changes the load points the Stock ECU reads its timing data from.

While the Emanage doesn't have the O2 skew table the MAPECU does it can still modify the O2 signal using the Analog Input/Output, this is only limited to changing the stoich point though, no RPM vs LOAD table.

I'm not trying to run it down, its an excellent tuning tool. I'm just stating the reasons why I bought a Emanage Ultimate instead of the MAPECU2

don't get me wrong here i wasn't bagging your chose i went by what you said that you seemed to know everything the map2 did so just pointing out a few finer points,
the 02 control is very important as the newer the car the harder it is to over come allot of things thus we put allot of time into the BD2 side of things as it'll only get harder as time goes on.
most cars now run wide-band before and after the cat and if any little thing is changed it'll shut you down,its a dam pain but i guess they do it to stop us playing with there technology
i maybe biased to the map2 but its very very easy to install and use, but its a free world and anyone can use what ever they like

[Leiden]

I was going to use the MAPECU2 in my NA-T conversion because of the built in MAP sensor and ability to remove the MAF using Elimination mode,

Only reason I didn't was because the VVTi in my vehicle relies on the MAF signal for airflow mass as it changes the overlap depending on airflow. If I skewed the input data it would put things out and without a VVTi controller there's no way to remedy the problem

Is it possible to add direct injector control in the future? Or even a VVTi signal skew table?

[steve murch]

we didnt bother going down that road as load signal is easier to do and less wiring,as for the vvti the map2 does do a afew pwm outputs and rpm so i cant see why it wouldnt work or we could write some software to do so

Sounds interesting, would be good to follow how it goes

Just a question regarding acceleration enrichment, how exactly is it calculated?

Say you have 20%, is that normally applied at maximum throttle opening rate? So for 50% opening rate it would apply 10% extra fuel. Also, how is throttle opening rate calculated? tps voltage / time?

there's many ways of mixing that % but normally its done from voltage( its what the ecu see's) and time taken against the fuel at that point and time on the map.
eg:if you base it against rpm then that % will be 2-10% as 20% is enough to put the light out.
i only use accel enrich if there's a flat spot after Ive done the tune but i never rely on it to cover a problem,you can also mix map with tps to help things along again it depends on the ecu.
only time ive used accel enrich more is on cold run

[Leiden]

I think my stock ecu uses a combination of TPS and MAF to calculate enrichment, I tried creating an airflow elimination map on my Emanage by entering the MAF values in for each RPM x MAP load site but could never get it to blip smoothly without a massive amount of acceleration enrichment added.

My only theory is that the ECU uses the MAF spike as added enrichment when the throttle plate is cracked open and all that air fills the plenumn

So what your saying is that with a properly set up MAF Elimination map there should be no need for big amounts of Accel Enrichment?

pretty much if its tuned threw out the map correctly you shouldnt need accel enrich,unless you have low engine vac or big cams to which when using big cams itll run richer with the overlap thus low engine vac.
forget about the fancy stuff and have it tuned to what its asking for then play with the add ons.
voltage reading from a narrow band is waste of time for tuning,i use a six wire wide band plus knock monitor and the seat of my pants.
tunign isnt an easy thing to teach it takes alot of time to know where to go to find power,its also more about how you get there than pike power which is easy to do.

[Leiden]

Im idling at about 16-20 in Hg (8-9ish psi below atmo) so that shouldn't be a problem

At the moment I'm pretty happy with it running MAF, I did play around with Speed Density a while ago but could never get it to run just how I liked. Plus the MAP signal was a tad noisy, it fluctuated by about 0.5psi, it was plugged directly into the plenumn though, will try a small fuel filter or Subaru 'pill' with a few inches of line to dampen things.

I'm slowly getting there, I've got the motor running alot better than it was a few days ago.

Old topic bumped... How does the new MAPECU 3 compare with the emanage ultimate in performance and tune-ability ?

[2jz tt Aristo]

Im also interested in this, like to support good ol kiwi ingenuity!!

[steroidcontaskie]

I have bought a MAP ECU 3 for my car, mainly because it can intercept the factory O2 signals and modify them so the OEM ECU doesnt retune the car to 14.7 when in boost (co's it is a Na-T project)

I guess the issue is really if there is someone that can tune it properly.

I will let you know if I have any luck, but I am still a little bit of work and a $1500 away from having a install and a tune.
