Has anyone used a 'Master Digital ECU Tuner 3' ???

I'm sure I could wire this in, but I'm not sure on programming it, any advice on this would be great,

Thanks

What is it, or what's it SUPPOSED to do?

Hi,

Here is the website -> http://www.ecumaster.com/ <-

It is a custom piggy back ecu, with programmable and selectable maps, the manual tells me to connect only to the MAF and Crank sensors but it can control injectors and other bits too, I was looking at doing a few maps for fuel and performance, and I think it supports 4 maps, but I know it supports 2 maps.

Thanks

If it won't control fuelling, I'd leave well alone.
If you don't know what you are doing, messing with the map of a Scoob engine is an expensive way to learn.

richard1982

As I said it can be used to control the injectors but its not shown connected to the injectors in the manual, also it's not playing with the map in the ecu as its a piggy back ecu that can be switched off. Thanks

OK, bud, your car.

Thing is tho mate, when its switched on it will be running the way you have told it to and if you have little knowledge of it (as you do because your asking on here) it could all go pear shaped very quickly

As said mate its your car and your money

Really no point running a piggyback ecu...

alcazar

There you go, one of the most respected mappers about.......

richard1982

The manual lets you control the injectors and the software will let me do a 16x16 3D map too

Please see the attached picture ...



Is no one interested in a look at this piggyback ECU ???

Thanks

Really no point using a piggyback when you can remap the original.

How are you going to run more boost than the oe ecu boost cut?

What do you think happens when you interrupt and reduce the maf signal?

is the esl not a piggy back ?

alcazar

iTrader: (2)

No, it's a daughter-board.

addi monster

iTrader: (6)

its still a piggy back though jeff not a stand alone..

richard1982

Just carried on reading the manual and it can also control the boost valve ... but it can only control the injectors and boost control if you fire all injectors at the same time, as it only has 2 how powered outputs ... or just control the boost valve on its own ...

Also a part from the manual
->DET3 device has the possibility to change the contents the mixture on the basis of readings from the narrowband
O2 sensor (NGO).<-

Best of luck, buddy, we'll commiserate when the time comes don't worry.

No it replaces the eerpom with the map in. It doesnt piggyback the signals to and from the ecu and therefore mask the engines real parameters from the ecu.

Piggypack refers to what it does not what it is physically.

Narrow band sensor is only accurate in cruise and idle, developed for emissions to keep fuelling correct for the cat to remove as much hc and co as possible which is ironic when most of the emissions are at full throttle but anyway. The standard ecu is altering the fuelling on idle and cruise using the narrowband sensor already. So why would you want to adjust it again?

Glad you cleared that one up as me and millions of others all thought a piggy back was somthing that was attached to an ecu ,, ? infact dont esl market these as piggybacks in there own wording ?, i hear what you are saying simon but a chip that can/cant be mapped that is mounted on an ecu is indeed a piggyback is it not hence the term piggyback

Jolly Green Monster

Two outputs? Thats not much use when you hsve four injectors

Jolly Green Monster

Physically piggybacks the ecu motherboard but it doesnt piggyback the ecu signals. It replaces the ecus map and is the ecu.

Piggyback in terms of ecu is more to do with piggybacking the signals.
Ie. ecu outputs a pulse width to an injector for it be open for 5msecs and the piggyback ecu is wires such that the pulse width can be increased or decreased therefore altering the amount of fuel injected. It piggybacked the injector signal. It can read the map sign and reduce it and send the reduced value into the oe ecu as another example.

The fact it is stuck onto the ecu, in the door pocket, glovebox is irrelavent.
In actual fact most piggyback ecus are wired in and stored somewhere near the ecu they wire into but dont actually physically piggyback the ecu.

So the ESL is indeed a piggyback

Jolly Green Monster

iTrader: (4)

NO!!!!

I dont know how to make it clear.

The esl replaces the ecu map. It does not piggyback the signals. Esl is not a piggyback.

addi monster

iTrader: (6)

You have just said in your post above that the esl is a physical piggyback have you not !

Gve it a rest mate: JGM spends time explaining stuff and is much respected. Don't take the p*ss, OK?

addi monster

iTrader: (6)

Sorry jeff but the esl is a physical piggy back as jgm himself has admitted and thats the only point i was making,
yes he is respected in the mapping field as we are in our fields

Jolly Green Monster

iTrader: (4)

it physcially piggybacks but a the definition of a piggyback ecu is that it piggybacks the ecu signals..

physcial orientation makes no odds..

ESL is NOT a piggyback ecu.

I dont think he is taking the pee, I think he just doesnt get it, am I not explaining it well enough or did his mummy drop him as a baby? meant totally in gest btw.

I am not sure how else I can explain it addi.. hopefully it is making sense now.

perhaps this might help addi? and OP might want to read it too as not interested in what people are telling him here, despite asking the question here lol

quick google search

simon the only point i was making is that the esl is indeed a physical piggyback which you agreed to did you not.
yes we all know it works in a different way to the OPs chip ect ect as it stores a full map not just changes perameters.
the bottom line here is it does mount the oe ecu thus being classed as a physical piggyback which in no technical terms can be denied.
