Hello to all and happy new year!
I need your help because I'm freaking out about the limiter turbo on an Integral first type, the 8 valves.
And' the model 185cv and (I attach the file ori) analyzing the file I was convinced that the limtatore was to address 003E01.
For testing I have set down, to the equivalent of 0.4 bar to see if it was correct, but alas, the pressure rises without problems up to remove 1.1, as always.
I could help who knows this ECU?
Thanks in advance!
hi all, anyone has info for this request?
thanks
I hope you know what you do in addition to the electronics with this?Originally Written by zioweb

perhaps 3ba0 for 10 points but it could be an overboost and not the limiter
whereas, I interpreted your answer does not clear you say yes, I know what I'm doing with these cars. I move with circumspection and only after having studied at modino.
For the 8v I can't find documentation and I rebuilt the addresses and the logic starting from the knowledge of the same ecu's mounted on a Ford Cosworth. I have also produced a handy def file for tunerpro.
I'm just missing the bit of the limiter turbo. You can help me?
But that 10 points was on the 16v where there was actually the manager of an overboost, on the 8v it seems to me there is the electronic management, BUT I COULD be WRONG.
I read that the bit was to take 255 but no one says which one is
3BA0 on the cosworth is the enrichment to fully open throttle. As a curve, the values and the conversion seems to be compatible so I think it's that.
The turbo in these ECU on a Cosworth that share the same hardware, and definitely "source" of the software, the limiter, the turbo brings it back towards the end of the map, where there is also the management of the pseudo-pierburg that mountain (AMAL valve).
In that area, the ecu of the delta is "empty", all to 255, for example.
I see this from a site:
TURBO PRESSURE AND LIMITER
This map controls the max turbo pressure which is allowed before the ECU cuts the ignition.
<Click for full size>
This map is 16x2 fields. There are 16 RPM breakpoints. This map shares the same RPM breakpoints with TURBO PRESSURE map.
The COLUMNS are RPM breakpoints. The Calculation is the same as with injection map and RPM breakpoints.
There are 2 ROWS. Second row is the max pressure limit. When this pressure is reached, the ECU will cut the ignition. First row is the max pressure set. When the ECU cuts the ignition due to reached max pressure, it will start working again, when the set value is reached.
At address hex 7650 follow the pressure limit and pressure set values. These values are 8-bit. To get the pressure limit and pressure set values in the bars you have to divide dec value with 170.
if you think that there are no curves, 3e27, and 3e28 may be two limiter activation and deactivation of the block?
I was referring to if you have experience racing on these..
You know you are weak in the head and tour if you have not made the right maintenance work to the engine?
If I can find the old HD that I have material a few decades ago, maybe I can help you..
"The only thing that stands between you and your goal are the********* continue to tell you why you can not reach it."
I looked at the file and I did not find, anyway, in other files, always 8-bit the turbo pressure must be divided by the 76 then you should find a number around 175, or as often happens a curve by 10 points
I am checking the settings of the alfa q4, but nothing, I continue to help you
