hi to all, repairing the ecu iaw 59f 5af and 4af gas me and happened to have the requests of the type : "I can modify a bit the ecu to make it go better?"
now we all know that these cars suffer from a bit of performance due to methane, but how should I do? which criteria to use non-methane???
available for read and write, I have the cdc marelli tour and kess v2 obd - titanium and winols to map.
what advice do you give me???
I've had requests like that...
I would like to know s? ? a thing possible...
A rider does not create queues even in the car...
a automoblista create queues even on a motorcycle...
it certainly is doable, maybe with some advice we can do that for sure...
Just anticipate???? seen that the values for methane are in another unit, it is not possible to anticipate, right???
what is urgently called for comparisons and tips
for what it is I have I can say that the values of advance cng cos? as those of the injection times are caught and corrected by the ecu to methane and gasoline...not s I if ? clear...
now the question? ? how will you act?? and especially on what ecu is needed of the two?
A rider does not create queues even in the car...
a automoblista create queues even on a motorcycle...
you should always act on the main control panel to gasoline.
as in any other plant pluricarburante, the interventions made on the main affect on the gas ecu without any problems.
I agree with t?.. but s? one is the perfection of the performance on Cng or LPG, after the gasoline, what happens?Originally Written by sergiot
will start? to knock (autoignition)?..
something you have to choose: if you are optimized to gasoline are a little less gas, and vice versa.
fortunately, c'? always in control of the beat, which forgives......
the performance, so the performance of the engine, with the petrol ? always higher when you go to lpg or natural gas...always!!!
if it's so? were not means of gasoline c ? something that should not be and ? to place it before making an adjustment to the gas.
with the modern cars, the performance of the pi? the top is to change the advance in all of its variables and the maximum adjustment should be made to gasoline (without the intervention of the knock sensor why? it would result in cuts and jerking) and never gas.
of course there will be? a small correction of the carburation on the petrol ecu to determine how to go into the partial and full load.
on the gas ecu, if ? well-adjusted after the remapping of the ecu gasoline, c ? need only small fixes.
well carmaghedon I've been of help, logically adjusting well to the petrol you have the benefits of gas... but mapping gasoline and methane, the methane after to be adjusted for better... ok so I need to reinforce a beautiful panda methane and see how far I can push petrol with the advance without detonating... and then I go to adjust the gas on his ecu... right??? I have drawn the right conclusions???
yes, but the eye that the tests without the knowledge does not bring benefits, especially when it comes to remapping
