Thanks giary74,so to recap and change 4 resistors, a built-in quartz??

Thanks giary74,so to recap and change 4 resistors, a built-in quartz??

Warning, the resistance important ? the one that sits in the top right... 3.9 K

After you replace only that, my cock is read in line K.

Then I checked also the four and I have replaced one (can't remember which)

Then I also changed the quartz and the HEF and some capacitors.
I don't know if I can post the full picture of the motherboard with all the changes... (I don't want to run the risk of me ban)

[motorsport]

it would be to replace the one in the top right of 1k ohm 3.9 k ??

giary74 I want to know this photo that you posted, there are already? all of the mod??

[giary74]

no, to see the photo with all the changes, do a search in ****** images with "rooster mbena"

I am new here.....thank you again everyone, for the help but I want to make a clarification ....the links of the forum that has given you the info for the changes I thank you infinitely...mbena!!!! and rare
find people so competent and available ... and at the first opportunity, I would like to reciprocate, but I want to make a clarification....
in the info give me there were changes thrusts that were in the capacitors ...the power regulators and resistances included two filters to cut off the output power on line obd
but the galletto v2 ver 52 come to me already had this many components that connects indicated.....
so I decided to go for step and I can confirm that today I have limited myself to change :

1) a smd resistor 1mm x 2mm for precision 1kohm was originally a smd marked 104.. by the way watching the mboards holding the obd on the left, the resistance number 4 of 4 the first to the left of the row between the two capacitors and the relay yellow (in my case black!!)

2) replacement of the resistor 103 smd present near the mc34063 in the upper right with respect to the relay....only the most recent at the bottom, with a value of 3.9 k (abbreviation 392)

3) replacement of the integrated hcf 140106b st microeletronics with a HEF40106BT REBRANDED PHILIPS NXP

4) replacing the resonator with a 3-pin with a crystal 16 mhz with a metal frame and only two pins.



I stress that, and need to replace the two resistors indicated...because by doing so
the cock becomes much more stable....of course fully charged battery ....

but I would recommend limiting yourself to these changes and does not proceed to the exchange
of the capacitors and to the application of the filters if you don't need to, and this is because
the same colleague who has made the changes he explained that, after having made
the change thrust I think I have understood that it has added a system with potentiometers
to change without desoldering anything the values in khom of resistors with jumpers appropriate because it was not working well with all the ecu.....

I didn't ask if he has proceeded step by step...but it seems not
and thus increasing the capacity of the capacitors and found, with a current output is not perfectly manageable!!) so to say
in other words, l the integrated philips manages the language with which to talk to the ecu
on the basis of their characteristics with a wave oscillatory in which is very important
the accuracy and the quality of the quartz... if you change too much power might become difficult if not impossible to make a box safe with some units
while others may work correctly...
I apologize if they are long-winded, I tried to use a simple language, but ultimately
limit yourself to my changes...then after testing on a variety of cars and a variety of control units
only if you have problems passed on to the next step.....capacitors strengthened and cut filter bandwidth!!!!!

this is my thought...I hope it's useful ..

[motorsport]

ok you have been very clear another thing that is important to where to buy these components???

[davidepar]

I hope that I bannino for this ....I'll just tell rs.....the rest you think about it!!!!!!!

ps to admin I hope I have not done damage.........

[motorsport]

no, to see the photo with all the changes, do a search in ****** images with "rooster mbena"

ok done now or a framework pi? clear.... now need to know where to buy these components if no, and useless to have this procedure,and how to have a plate of cannelloni without preparing it!!!eh eh eh

I hope that I bannino for this ....I'll just tell rs.....the rest you think about it!!!!!!!

ps to admin I hope I have not done damage.........

thanks you have been very kind,I do not think that you did no damage because you have not posted any link,the two initials that you posted I do a p? l riddle, and let's see if I can if not,' consulting the crystal ball, let's see if I can find this supplier hihiihihihih

[carlo abarth]

thanks I'll keep in mind for availability!!!

These are the changes which he sportknight
