Purchasing an MPGuino
 

Hey guys,

Im new here and am willing to buy a Kit of any sort to get my hands on one of these.

Been waiting for 6 months for these to come available (tried purchasing twice through paypal but had to get refunded both times as there had been several problems)

Is anybody Able to help me Obtaining one of these or even get a full parts list
?

Hi,
I have some pre-built mpguinos
More details here: http://ecomodder.com/forum/showthrea...ino-20362.html

Hey bud,

Thankyou for that, I would like to buy a pre-assembled unit in full metric with seperate buttons if possible?

Only problem is I can't pm you till I have 10 posts :P

Also, can you supply without the LCD screen if we supply our own?

And how long can you have the buttons extended by?

And do you have any pre-made cases for these? Doesnt matter if you don't :P

I can ship it without LCD if you want and give pin header for LCD soldering (-3.00EUR)

It has about 15cm cable so you can mount buttons right-side or left-side of the screen.

I dont have pre-made boxes but I can make similar like I have if you want (+2.00EUR)

Pm sent :)

EDIT*

If anybody could help me with a parts list i could build it myself here also? i did try searching for the parts list here but all i found was graphs :S
weighing up my choices :P

If anybody feels like going through these to tell me if there right or wrong to build a MPGuino that would be wonderful :)

only thing missing *i think possibly others* is the 'smaller capacitor... i have no idea what type that should be the yellow one that is

Still some mpguinos available....

Mpguino is built in custom etched PCB and is same size like LCD (sits behind it, electrically it is compatible with "official mpguino"). I am using atmega 328
Price is 59euros + shipping (4.8eur) and paypal transfer fee (depends on buyer country 3.5-4.5% + 0.35EUR).

more info and pics

I have also made custom code (based on 0.75) just like I like it
extra features:
* added metric version (must choose before code/firmware uploading, no change possible in settings)
* bargraphs (shows 2min average 5-9L/100km - dropped 0-5L to gain better resolution)
* battery voltage
* trip cost (in settins you enter fuel price)
* current trip does not reset automatically after 2min engine off. Manual reset like tank trip.
* tank trip time in hours.minutes, current trip time is now available too
* saving tank trip data to eeprom (dont forget it when disconnected)
* some values are shown in integers (speed, rpm)
* removed leading zeroes (instead "012.45" shows " 12.45")
* added dragrace screen (0-100km/h time, 400m time and trap speed, calculated horsepower)
* using Atmega chip sleep mode (consumes about 5milliAmps versus 20milliAmps when in sleep)

Compatability
 

Would this work on a 4.3 liter TBI engine? Will it correctly monitor a throttle body injection?

meelis, would you be able to ship a unit to the US? And how would I hook this up to an aftermarket speedometer? I would think there would be a SpeedSensor wire back there

Hi,
I made quick search and found this page
http://ecomodder.com/forum/showthrea...ino-14552.html
more links here (use brauser search "TBI")
MPGuino - EcoModder


I dont know much about TBI so I cannot be 100% sure that it works. If TBI means that you have one injector, then it should work.

I can ship worldwide (same shipping price 4.8EUR)
Speed pulses should go into speedometer - how otherwise it can show your speed?
Check your speedometer manual.

I am also wanting a mpguino

and need 10 posts to pm you

very happy that you are building pre-assembleds

sorry for pseudospam

You can also connect me and order directly from MPGuino trip computer - MPGuino

Nice way to increase post counts :D

Hey I would like one as well but with a enclosure and reads mpg.

MPGuino displays MPG by default, or what you meant? :D
