Hi Roger.
I m ecstatic by the smooth function by the setup 30,87a (no oxygon sensor).
I se the iddle speed by the big screws on throttles (2 full turns) to 14,7 :1.
Also i make the injection map :
1,100-1.900 14,2:1. If you make idle AFR 13.5-13.8:1 your bike will idle even better
2.000-3.000 13,8:1.
3.000-4.000 13,6:1.
4.000-5.000 13.5:1
5.000-6.000 13,2:1
6.000-79000 12,5:1.
Remember on an Open Loop bike these AFRs will get leaner by 0.5 AFR if you run fuel with ethanol. So the table would be the equivalent of:
1,100-1.900 14,7:1
2.000-3.000 14,3:1.
3.000-4.000 14,1:1.
4.000-5.000 14,0:1
5.000-6.000 13,7:1
6.000-79000 13,0:1.
The bike works fine, the power is linear at all engine speeds without faltered. The AFRs are possible for OPEN LOOP bikes like the R1100GS with Brown Plug, but not on Closed Loop bikes like the R1150s or R1100s with Oxygen Sensors active.
At the future i will buy a engine R1100S and i fit to my GS and i make the settings again 30,87a by no lambda sensor. I think will work like racing bike, like carpyrator. The R1100S engine uses the Motronic MA 2.4. It only operates in Closed Loop with O2 sensor. 30-87a won't work on it.
The only problem by this setup is the consumption.
The consumption by lambda sensor (on) is little better. By one tank (22 l) i make 330 Km, now i make 280km but anyway does no matter, i keep this setup for enjoy. I agree with you, it takes added fuel to run at best power mixture but for me too, the joys of riding that bike exceed the lost mileage.
By the way Roger, i make all test with LC2 on my bike with stock (lambda sensor on), i drive 300 miles, there is no longer adapt. On a stock bike with Lambda Sensor on, and no-ethanol fuel, adaptation is small and quick. But if you make big changes to the map, it takes much longer for the Motronic to "erase" them.If you still believe that there is a longer adapt, the solution is very easy, just fitout the fuese 5 from the fusebox for 5 min , refit the fuse 5 again, open the key without start the engine and open 3 times the throttles and start finish the bike again. Resetting the Motronic is not a viable solution. Yes, you erase Mixture Adaptation and start over, but you also erase the good functions of adaptation. Also, who wants to reset their Motronic every day or two. (Yes, every day, although full adaptation takes a while, partial adaptation is happening right away. That makes zero maps to load agains.. So there is any problem anywhere.
There is only a short adapt after 4-5 miles until the ECU load all maps (the ECU isn't loading maps for adaptation, it is slowly calculating new tables as I described above but this is physically, happen to all ecu.
And as i said by higher value to maps :
1. Main injection map. Should only be changed in the Open Loop area
2. Atmospair map.No need to change, same AFRs work at all air pressures
3. Air intake sensor map.Should not be changed, it will slow the mixture adaptation process
4. High mountain map. Yes, you may find better timing than stock
By all these higher values, the bike (with lambda) works smooth by little more richer fuel. The AFR is 14,7 only when the thortles is stable. Closed Loop is happening 40-80% of the time. That is ok and help the more consumption. On aceleration the fuel is more richer than stock maps Even on a stock bike there is a large acceleration enrichment. You should try to find the tables for TPS movement and TPS rate-of-change. Those will add fuel that doesn't get erased by mixture adaptation, that is the best for power and faster speed.
Also by mods at maps :
1. Ignition advance map (faster).
2. Expand ignition to the sparks. Some bikes benefit from longer dwell times but at high RPMs you could overheat the coils. Stick coils will have a problem with the heat.
3. Faster timing advance to full open throttles. This is probably the reason why your Dyno numbers are better.
4. Little corrections advance when the engine is hot. Probably helps
5. Variable values to main advance map. Probably helps
All these gives :
30% much better torque at 1.100-1.900 rpm.
15 % much better torque at 2.000-3.500 rpms.
10% much better torque at 3.500-5.100 rpms.
And 6-10 plus HP at high revs of rams. Remember your Dyno plots are only measuring about 6 to 8 points out of 288 (or more) in the fuel map. And they are only telling you HP and Torque for small fractions of a second at each point.
I m sure now that my 4 years hard job is worth. (You are making progress.)
The cost of my chip is much more cheap than others (lazer, bbpower) and any other, also it is free (no locked), it is open software, everybody can see what i make. Also i try management for very low cost.
I try many chips, lazer, BBpower, Germany;s chip, really it is true that these are worst than stock chip, no improvement anywhere. You and I agree about those other chips.
Fianlly i have to say that the chip is just a remaping chip, update for the 20yeras old stock chip. better by great results.
Anyway Roger thanks for talking, you are my teacher for many ideas and information. Thanks, but I still have to help you understand Mixture Adaptation, and persuade you of the value of Lambda-shifting. If you lambda-shifted with LC-2 or AF-XIED in the Closed Loop area and then adjusted maps in the Open Loop area, your chips would really be good. Until you try Lambda-shifting, you have no idea how good it is.
Regards
wow am at a loss.
