Diego G3-Injection-Fehler

Hi, first of all: Your English is not bad, we can understand you very good!
You gas pressure with 1.16 bar is fine for the beginning. When driving the pressure will drop a little bit, then you get closer to 1 bar even more.
This reference pressure is really only a reference. Don't worry about that.
But if the pressure was setup correctly for your engine we can not see, because your pictures doesn't show any gas points so far.
After installing new injectors and changing the gas pressure you have to setup the KME from the beginning. I think this step was not done.
In the 3rd picture the engine is running in idle, here I can see that the engine is running too rich.
Run your car with gas a few kilometers and show 2nd and 3rd sreenshot again.

 

Hi, you have to do 2 basic things:
1) setup offset
2) setup MULT

How to do that?
1) Let the car warm up and running with gasoline at idle. then read the petrol time (2nd value from left). Switch to gas then and read the patrol time again. With changing the offset your goal is that petrol time doesnt change when you switch from gas to petrol and back. a change of 0.1ms is ok, but no more then 0.2ms

2) run a gas map: drive the car with gas with 1700-2700 rpm. you need different engine loads in this rpm range. during this drive cycle the KME collects gas pints automatically. Then compare these gas (green) points with petrol points (red) using the screen 3 (Map).
If green points are laying over red points engine is running lean and you have to increase the number of MULT. Do the opposite if green points are lower than red points (engine is too rich).
If green points and red points on the same line you should check again offset and correct if necessary.
If MULT is lower than -10 your gas pressure is too high and needs to reduce further. After that do 1) and 2) again.
If MULT is bigger than 15 your gas pressure is too low. Correct it and do 1) and 2) again.

First you should correct the "working pressure" field, there you still have 1.2bar, type 1.1 to it.

You can also press the autocalibration and let you gide through all necessary steps but I recommand the manual way.

 

Yes, 2.5ms offset is an indication that MULT is wrong (too low). To say more you should upload a picture of your gas map.
The setup of MULT and offset needs to be done alternating. After one value is ok you do the other value, then the first again. Do it 2 times and you are done.
If the gas pressure is in range you can see on MULT value after the complete setup was done like I already wrote.

If you can not reach a good value for MULT (-10..+15) and you should have to change the gas pressure more than you can (0.8-1.3 bar) then you must change the nozzles of your injectors or clean the injectors or correct the swing of your injector piston (Magic Jet, Valtek) or you are using wrong injector for this engine (HANA).

 

You can use HANA for your engine and for your brothers engine, no problem. But there are different types of HANA.

I wrote "If you can not reach a good value for MULT (-10..+15)" and your gas pressure is out of range 0.8-1.3 bar then your HANA type might be wrong. But don't worry, do the first step as first: Find correct values for offset and mult, then decide if the gas pressure needs correction (and if so don't forget to setup offset and mult again).
Why is your gas map always empty? KME collects gas map when ever you drive in selected RPM range. And if the KME deletes gas map it asks you first. Simple say "no, don't delete my gas points" when KME ask for it.

 

Ok, if green points are higher than red points you are running too lean, now increase MULT a little, maybe add 5 to old value and drive again a new gas map. During these steps it's ok to delete old gas map.
Your petrol map is also not good, drive some km with petrol in selected rpm range when engine is warm. Do some acceleration when collectin map points with gas and with petrol but don't leave the RPM range.

 

Hi,

set the Offset down 1.5 - 1.8.

MFG

 

Hi, I agree with W8LPG. With 2.5ms the offset is much too high. A typical value is 1.5.
Try this number and wait longer (2-5 minutes) when you switch from gas to gasoline and back. Then check the values.
But first let the engine run in idle for 10 minutes and note the gasoline time (I think it is ~3-4ms with you car?).
Engine must have it's final temperature when you do this.
If your result is bigger than 2ms there is still something wrong. Maybe the oxygen sensor but you already changed it?
In this case keep 1.8ms as offset.

Or maybe there is a misunderstanding?
You must keep the petrol time staying the same, no matter if engine runs under gasoline or gas.
If you increase the offset the petrol time will go lower if you are under gas.
Your lamda regulation needs some time to correct the petrol time, that's why wait a little after you switched from one to the other.

 

Hi,
yes, gas time and petrol time are different, this is normal.
Gas time = petrol time * MULT + Offset. (+ here not important extra correction for gas pressure and temperature)
If MULT is 7% then take 1.07 in this formula.

Yes, if you take back offset then mixture is getting lean when engine runs in idle. But offset is not responsable for the setting when engine is doing it's job (driving).

I think first you should check if your lamda system is working correctly.
When engine runs idle you should see that petrol time is going down if you increase offset and vice versa.
So adding 1ms to offset should reduce petrol time by ~1ms.
Check out how long it takes if you see the reaktion on petrol time after changing offset.
Does this car have OBD or can you test for any engine issues somehow?

 

Hi, what shows the lambda sensor if the engine runs in idle wit petrol. Also too rich?

Difference between gas time and petrol time (your car 2ms) is not important and 2ms is ar typical number and ok.
I see your gas prssure is 1.05bar in idle, this is ok, but you must change "working pressure" setting in the software to 1.0 bar then (~0.1bar less than idle gas pressure).
Because of this setting your KME enrich the mixture a little bit because it thinks your gas pressure dropped a little bit.
Correct this and drive on gas a new gas map and show us the result. Make sure you have >50 red points for petrol and green points for gas.

 

If you have same problem (high fuel consumption) running with petrol you should think about other components mass flow sensor or air filter or what ever your car supports.
