Carsdoft 7.4 mercedes

[corland]

Hello all,

I wanted to know your opinion on the carsoft 7.4 mercedes.

I took a multiplex 7.4 to troubleshoot and monitor a problem of consumption of my sportcoupe w203 2003.

convinced of his ability to see the data from the engine control unit (edc16) I had the unpleasant evidence that does not connect with the ecu.

All I see is good almost all the others... including that of the exchange drive that I would never have told you to read...

According to you there is no way to do it ? maybe by moving the pin assignment of the connector ??? I doubt that it is only a matter of multiplexing wrong since version 7.4 should read all of the machines up to 2004...


according to you, I hope to do something????


Thanks to all

azz how many answers !!! DOHHH

azz how many answers !!! DOHHH

hello strange that you do not link should go well from 1996 - 2004

with autocom then see a whole of things, with das all....

thanks for the reply
in fact, I picked it up because I was hoping to see something about gl injectors.. but do not connect with any of the units!!
with regard to autocom... I also have one.. it's so good. But nothing about what I needed!
After that I changed the swirl I have serious problems of consumption.. before redo the ecu I wanted to understand what happens under the 2000 rpm where it seems to be too fat..

hello house, we have the w203 sedan but edc15, the injectors do not see them with autocom. I have problems on the ezs are tt deactivated keys

s?iega the problems that you have

s?iega the problems that you have

the problem is simple !!! removed the swirl and the egr... all perfect. but the loss of performance and fuel consumption is high. Especially under the regime full of the turbine, where the well-known smoke and a drop in performance. I believe that you disable the swirl mechanically and not by the map has helped.. but before acting on the rail pressure and the torque limiters I wanted to be sure not to have any injector out-of-phase. Hard to say... and go in a mercedes would do little seen, which do not provide for this type of changes, and their quote for the repair was around 1800 euro.... unthinkable !!

the ecu is a edc16. and the medium has the nag5... then before each change I wanted to study at the bottom of the pattern and figure out how to change every particular, without going to trial... the thing that I hate to do a priori, without a minimum of theoretical certainties!!!!

unfortunately, I have asked several times to the opinion of someone who has more experience... but no one wanted to ever share your opinion ! so look.. in the meantime I have made over 10000 km, and everything is stable. Even I noticed that it consumes less taking the engine above 2000 rpm. And the computer board obviously takes the butterflies.. even indicates consumption of close to 20 per litre when I don't I get even with the wind at your back above the 13.... an exaggeration !!! at the best of times, I was always next to the 16..

hello then the swirl and the egr you should first close them from the map before making them mechanically, it takes you to an imbalance.( I speak from what I understand from the forum). before the consumption went well and the response?
excuse in the 1800's, preventive interventions had to do on the machine? with autocom you can not see the values of the mass air flow sensor, rail pressure etc.***** and it involves the exchange 5 nag
that errors have the ecu ?how many miles has the car? as the gear oil nag5?

the egr is already closed by the map ... the swirl unfortunately, no. I had some problems with the damos and insecurity do not have them removed. In the 1800 euros changed manifolds, motor mounts, ecu auxiliary heating and glow plugs. All things that I have already fixed ... the medium has 300000km... for what I don't dare to make changes without being sure. But it is perfect and does not consume oil for nothing. the transmission was rebuilt 100000 km ago... so all is well . the values I see all of them with autocom... but difficult to interpret if you don't have of the absolute values of reference as may be with the star.. a short lighthouse' accurate control of the mass air flow sensor to see if it falls into the standard or at least with loscilloscopio ec the face to get to the maximum voltage. for the rest I have no other ideas.. everything seems fine.

hello that errors from the engine and transmission(enter autocom in the exchange?) ? the swirl you should remove them from the map to eliminate the loss of power (according to me), I can't help you I've never done it.
the exchange should have need of a change of a dry ( every 60000 km), if you have any error can be or that should be replaced on a socket.
cos? not ? simple without knowing a minimum of things, if you can by a p? values.
