Performance Motor Research MAP-ECU

[wytbishop]

Has anyone used this system? I like it because it's cheaper than a standalone, but offers lots of adjustability. It reminds me of the Power Commander on my bike. Sounds like it's easier to install than a SAFC and has all the same functions. With the Manifold Absolute Pressure method of metering air, you would eliminate the entire airbox and VAF completely. Something would have to be fab'd to arrange the cold air idle, but I don't think that would be too hard. You could control ignition, boost, pretty much everything.

Anyone have any experience with this system? Any thoughts?

iv been planing on going with the MSII system but would like to hear more or get a link to look at the one your talking about

What you basically have is a "piggyback" system. It replaces the Vane Air Flow sensor system (VAF) that your stock engine uses with a Manifold Absolute Pressure (MAP) system of determining the amount of air entering the engine and thus how much fuel to deliver. The difference from MS is that it does not replace the existing ECU, it simply intercepts the outputs to the fuel and ignition system and adjusts them. The stock ECU collects most of the data (some inputs are replaced or altered by the piggyback) and the piggyback system tells the engine what to do.

This means, in theory, much less wiring than a stand alone, but with almost all of the adjustability.

wow that sounds cool i would like to go your way if its as cheap as the msII system how much dos it go for and where do i find one

[wytbishop]

$399+shipping for the original which is fuel only or $695+shipping for the ECU II which seems to have more features including the ability to control ignition timing and has several auxiliary outputs for things like wastegate activation, O2 sensor control and on and on.

Just seems like it might be easier to use than some of the others i've seen. I was hoping someone on the board might know a bit about it. I've found that if there's a product like this that no one's using, it's usually for a reason.

lots of people use the MSII iv seen them talk about it but no one seems to know any thing about it or have any info for me about it i have a post up about using the msII cause i just got a gt25 turbo and manifold im going to be puting on a mazda bp i got from an escort gt i have read alot about it building it is and thats not the scarey part the scarey part is with the tunning i can have wiring and every thing for full stand alone for around 700 the ecu its self i can have for 245.00 then you need lots of little things to go with it so yours sounds cool but what do you get for the money do you get wiring and every thing or is there any thing you need to buy to make it work when it comes to Engine Electronics/Tuning this grup dose not seem to be alot of help but i hope some one proves me wrong and speeks up

Well...first of all...there's lots of info about MegaSquirt on Probetalk. You'll find much of what you seek there. I don't know much about it, but there's a guy there who I believe is part of the developement team for MS. He appears to know everything there is to know about it. His avatar says "MegaSquirt Help Desk". I don't know if that what he actually is, or if it's just a joke, but he seems to know stuff.

Second of all...grammar...punctuation...seriously...give it a try. People will be more likely to respond to your posts if they're easier to read.

I don't know what other accessories a person would need to make the MAP-ECU II work. I'm sure you could get that information from them. I've read their instruction manual and it seems like it's all there. You have the option of upgrading the ignition system, so you could go with a coil for each cylinder if you wanted, but you can leave it stock and it will work. You can upgrade the O2 sensor and the system will allow you to control it, but again, I think you can stick with the stock one. There's some wiring to construct but that seems like it.

"Simple piggy-back installation only requires 7 wires to operate with no major re-wiring of OEM components. "

Sounds too good to be true, so there's a good chance that it is.

I use the map ecu in my bp-t mx-3.
so far the car runs a little funny until it reaches operating temprature,
and then its great.

[wytbishop]

That's very good to know. How much boost are you running? Any special difficulties in the install? I think this is a good way to go for low boost budget projects.

I believe mikee from http://www.jeroentje.nl/ used this http://www.jeroentje.nl/index.php?page= ... d=50002400 piggy back for his klze turbo nos setup as he was selling his set up on our UK-mx3.com forum. Perhaps he/they can enlighten you to piggyback tuning

I also like the nos window outputs which seem like they could be used for VRIS points for our curvy necks

Price: € 575,00

Discription:
The MAP-ECU (Manifold Absolute Pressure Electronic Control Unit) is
designed to provide two main functions:

Removal of the stock air flow meter (hotwire, flap, and Karman-Vortex style) and conversion to speed-density (MAP) based tuning.

Complete control over your OEM ECM fuel table by tuning the air flow signal traveling to the ECM, allowing you to install larger injectors, forced induction, or other major engine modifications.


The MAP-ECU kit includes: MAP-ECU, loom, PC CDROM software, 2 metre serial cable, air temp sensor and manual in PDF format. The MAP-ECU works on BMW, Porsche, Toyota, Mitsubishi, Nissan, Honda, Subaru, Mazda, Proton, Hyundai and most other late model fuel injected vehicles using most major types of air metering systems (hotwire, flap, and Karman-Vortex) found in use today. It can be installed on any 1-16 cylinder engine in less than an hour, and completely replaces the restrictive factory air meter. 'No special fitting kits or special adaptors are required'
The benefits include:

More horsepower and torque by removal of the restrictive factory air meter.

The ability to use the stock ECM to control larger fuel injectors and/or performance upgrades

Retains the daily driveability of the stock ECM usually sacrificed with a full aftermarket engine management upgrade.

Built-in manifold pressure sensor capable of reading up to 30 PSI boost pressure.

Real-time tuning using WindowsÆ based MAP-CAL software supplied with the unit.

High-resolution 374 point table (0-8000 RPM and -10 to 30 PSI) allows fine tuning for performance and driveability.

Built-in display and logging of key engine parameters such as RPM, Throttle Position, Boost Pressure, and Airflow.

On-board support for display and logging of popular aftermarket wideband Lambda sensors/controllers.

On-board programmable NOS window activation switch can also be used to turn on other accessories at set RPM/PSI points.

Simple piggy-back installation only requires 5 wires to operate with no major re-wiring of OEM components.

this is exactly the unit I have been researching. I will look him up.

Thanks

No problem, let me know your conclusion - I'm considering it also, if it can control both VRIS it would might just do me. Though no spark management, but the ease of piggy back... ah decisions...

[wytbishop]

The unit shown in that link is not the most current unit available. The MAP ECU2 has spark control for up to 8 channels.

I know Mikee and Jeroentje. With the map ecu it isn't possible to controle VRIS

[wytbishop]

My ultimate plan is to get in the 300whp range. I'm not sure if the VRIS will be part of my final result. I may manufacture something custom (all this education has to pay off sometime..lol) for an IM. I'm not sure if the ECU2 will do everything I want to do...but it sounds like it does alot. I have been browsing their help forum and people are doing some very complicated stuff with it in conjunction with other control units.

I think I'm going to pick one up this year and just use it to replace the VAF and tune the fuel delivery. IN the future I want to experiment with going distributorless....maybe even coil on plug...with the help of an ignition controller. Then the turbo stuff is mostly just fuel management. There are many users on their forum who are doing much more complicated things than that.

We'll see. I just managed to trick...I mean talk my wife into letting me keep the black 94' for a project car.

We'll see what happens.
