m-tdi timing

[ryanp]

the 1.9 N/a bracket will be ok aswell then??

just to add to this thread, does anyone have access to the proper TDI timing advance curve?  timing @ 1k rpm & 2k rpm?  i recall seeing this on the forum a while back, but forgot which thread had it.  this would be good info for calibrating the pumps advance.  or even finding out what a 'performance chip' would do to the advance, and then implement that to the mechanical pump.

that would be good info to no and then use a difrant spring and end cap to get the right curve and max advance ,

[oldskool rich]

yes i second that, i would like to know a better timing position, though i doubt the injectors will either fit or increase performance but worth a look

i could finish my car in a few hours but ive been so busy doing building work im not gona have time for a good few weeks at least :cry:

[Hey]

I am building a LCD screen that will give me injetion time (in crankshaft degrees) and injection timing using the #3 injectr and crank sensor on my mtdi... the design is done... I just need to find some time to build it.

On the other hand, somebody came up with the idea to hook up a tdi ECU on the #3 injector and crankshaft sensor... that would give yo acces to vag-com, timing and injection quantity !!

Then you can compare with this stock timing map

Hello everybody! I m trying to optimize the timing of my 2.8 l ATA Pump too. I got this AFN time table from a friend! Perhaps it could help us!

Hi all, i'm fascinated with this topic. I have an engine out of a 1998 turbo diesel iveco daily. Is this the tdi engine you speak of??? Always thought it was only td and not tdi??? If it is tdi, what mods are needed to run it on a 110tdi in my mk2??? What is the setup with the injectors??? Cheers guys.

Any news about your Timing Display? Could you announce a wiring diagram?

[Hey]

yes.. I have a tdi ECU and all the connections... so I will use the ECU and only pug the injector +crank sensor for injection quantity and timing.

BUT.. I could build the schematic for you if you want... I could also make the code for the microcontroller but I won't have time to test it really soon so if you want to test it... I can do it very soon.

That would be nice! But I have never programmed a contoller yet. I think Im able to create a board out of a wiring diagram, but i would need your help.

Holy CRAP you guys are GODS.
I'm going into computer science in university. Oh jeeze i would LOVE to do what you lot are getting into          

[Hey]

Ok... this morning I finished creating the PCB wiring and the code.

However, I have NOT tested anything yet... if someone wants to do it.. it would help everyone.. including me since I don't have time right now to do it. If someone wants to do it, contact me BEFORE so you will know if there is any changes to make to the PCB or to the PIC programming.

Here are everything that you need to build a tdi timing (and injection quantity in crankshaft degrees) to LCD. I will soon make a DIY on how to build your own PCB easily.

If you need to buy a programer for the microcontroler you can look here:

or here
http://www.electronickits.com/kit/complete/prog/ck1708.htm
or on ebay

(be careful as some may need a power supply as extra cost)

anything that can program a PIC 16F876A is good.

This is the circuit as seen from top. (the second layer is shown in red.. just use 2 wires)


You will also need this file to create the PCB itself
http://www.4shared.com/file/100273995/80ba12ef/timing_to_LCD_PCB.html

... here is the components you will need and where to place them:
http://www.4shared.com/file/100274015/da659bd1/timing_to_LCD_V01.html

and... the code to program the microcontroler
http://www.4shared.com/file/100274542/3fbd38dc/Timing.html

for now... the code only shows timing... I didn't had time to implement the injection quantity.

-R3 needs to be adjust so you have at least 12.5V at the crank and injector connectors

-R10 needs to be adjusted close to 2.7k PRIOR to installing. In fact, it needs to be adjusted so that if you replace the injector connector by a 10k resistor, you will have 0V when you put the resistor and 5V when you don't put it AT THE TOP RED WIRE.

-R27 needs to be adjusted close to 6.8k PRIOR to installing. In fact, it should act just as R10 but you might need a 1M resistor to make the voltage change from 5V to 0V AT THE LOWER RED WIRE. This one is less difficult to adjust.

-For the LCD, you can use a connector so that you can place the LCD apart from the PCB.

-The crank sensor has 3 wire, only two are usefull, the signal needs to be positive, so you might need to invert the wire if it doesn't work (don't know yet which one to use). I will tell when I checked which one to use.

-The same thing happens with the injector connector, the signal needs to be positive first, so you might need to invert the 2 wire if it doesn't work. I will tell as soon as I have my car back (one of my friend needed it for the week) but I think that the connector at the left when the connector guide face the sky is the positive one.

Finally... when you build it.. my phone number will show on the LCD... give me a call!! lol!

You sir, are a credit to the community ;-)  How long did you study/train to be able to do something like that so quickly?

[Hey]

Thank you!  ...  I learn all that by myself because people in the electronic community were very nice and made documents like these. I have been doing electronics in my freetime for 2 years.

I have to ask a lot of questions some time to make those circuits... but this one was easier since I already had all the "parts" of the circuit made for other projects.

For the programmation part, I am doing doctoral studies in physics... I specialise in programming code to calculate much more complex things... that helps a lot!! lol!


If you want the French version of the how to make a circuit.. go there

there is also the schematic for a VNT electronic controler as a bonus.

[snakemaster]

any one built one of theas things yet , how easy was it ? how dose it shape up ? want to make me one :wink:

[Hey]

I am close to building/testing it.. I tried with a tdi ECU and it was not that good to setup the timing because you have no idea of the injection quantity in degrees.. so it is difficult to adjust timing!

The boost controler posted elsewhere (idi section I think) works fine though. I run one with VNT17VA and my dad also runs one on his dakota m-tdi with VNT20
