But I still have a problem with my Lambda sensor. As You can see I have constant voltage of 0.2V. The same is in GuzziDiag. After a 10km ride my engine reach constant temp of 117°C and even once during this ride Lambda haven't turned on. I've checked my map and it is a stock map. Both my lambdas are on. No DTC. Everything is working like it should. ????
On a 2000 Jackal, what should the TPS readings be? I've found the readings for a meter, but not sure what degrees I should be expecting. Also, should I be reading it with the linkage connected or disconnected, engine running or no? Thanks!
If engine is warm, and running 3 minutes, at idle, you should be able to see the lambda regulation value change and after that the integrator should work too. It should be not to cold, the air temp is leading, at least 20 degree's C and engine over 30 C
Ok I will check that tomorrow. I've got one more question. Did You ever tried a map from Griso 8V in your Stelvio? Did it improve the power and torque? Comparing those two maps an obvious thing can be noticed. Griso gets much more fuel. I've compared also the engine parts. Intake air duct is different but rest of it appears to be the same. So where are those horses from Griso? Is it possible that this is just a different map?
Yes, the engines are exactly the same, but as Paul says, a map from one lambda bike won't run in a two lambda bike.
But it IS possible to copy the values from some of the tables in a 1 Lambda map and paste them into a 2 Lambda map. e.g. main fuel or ignition. Sent from my iPhone using Tapatalk
This is not a problem problem for me since I've got a single Lambda system in my 2011 stelvio. Actually I don't need more power. But some extra torque around 3000RPM would make a huge difference. The same situation I've had with my BMW. I added a Power Commander to gain some torque in the middle. Huge difference. Max power and torque haven't changed. So I will probably add a LC-2 set and emulate two different lambda settings and connect them trough the switch to the 5AM to maintain desired AFR. I know that the Lambda input in 5AM is differential but there won't be a problem with that. Two quick questions.1. Is it posible to connect negative lambda 5AM input to GND without burning anything?2. If not, what a negative value of potential will be between negative Lambda connector and GND? Or it won't be at all? Anyone have any information about that?
It is possible to connect the lc2 to the lambda input, I have a lm1 working this way. But don't rely on lambda tuning, by changing lambda value. Better switch of lambda and get a better map.
I know that Guzzi is totally different than BMW. But there, I firstly tune the PC to desire AFR to set the optimum value and than I played with the map. Since map is being used only when ECU is in open loop so it will be when you accelerating or decelerating significantly. Than values from the map should be relevant. I've set my BMW in way, that when I riding steady and than open throttle on max at around 3000rpm my AFR is constant at 13.7:1. Without any jumps up and down on acceleration and deceleration. It is not an optimum value. Bike is running the best on 13:1 but than it consume a lot of fuel during cruising. Using LC-2 would let me switch (by external circuit) between first and second output to choose designed AFR.Pauldaytona how did you connect those LC-2 outputs to 5AM?
I have a wire(analog out from lc-1) on pin 1 of the lambda plug on the bike. The ecu works different as you think. It has a main fuel map and main ignition map. On these maps are correction maps, like temperature. But also the lambda corrects that main map. But only as you drive constant and not to fast. And the correction value it has, accumulates over time as a correction on the whole fuel map. You can reset that with the autolearning parameter.
Did You disconnect your Lambda sensor totally or just pin 1 or 1 and 2? I think ECU has a heater detection and maybe also the sensing detection. Every ECU is different. I will figure out how to tune this one primarily. Did You made a change in any of delta maps? Those values should not be changed since they are related with the intake and exhaust properties. And in the same time they should be changed when new exhaust where installed.
Does anyone know where I can get a V11 map?I have a H-pipe, Mistrals, and an open airbox, so a map for those or similar mods would be a plus.
I can send you a stock V11 map. I don't have anything for those mods though.
Sigh. You don't want back pressure. Back pressure is bad. At lower rpm's you need go keep the exhaust velocity high to maximize torque. That's how EXUP systems work. They don't increase back pressure, they increase gas velocity. The higher the gas velocity, the better scavenging. The less power the engine uses to push the exhaust gas out, the more power goes to the rear wheel. Adding a restrictor to the exhaust will completely mess up the fueling. You will need to change the main map, ignition and delta fuel. It's a waste of time and an exercise in futility.Guzzi have tuned these engines for a good overall performance on the road. It's not designed as a torque monster to pull down small buildings or a power monster to race RSV4's. It's a compromise.If you want maximum torque, design an exhaust that is longer and sized correctly. Or build an EXUP system for it.And yes, there is current sensing in the ECU for the lambda probe.
Yes that is possible, but the tps values are different so what you copy from one table, doesn't fit the tps values in the other, so yes it will start, but you certainly get different running
I was analyzing the single and double lambda stelvio's map. I use a XDF from a GuzziDiag web page (V1.29) and Tuner PRO build 5.00.8519.00. When the double lambda stelvio's map was loaded (double lambda XDF) I've noticed that the Ignition ADV map was corrupted. At the first glance everything was ok but the values of 65 degree was... to big for me. Differences between single and double lambda system was about 15 deg. Every other map was ok. So I use a different program. ECM Edit & Custom Map. And there everything was ok. There ware just a minor differences between between single and double lambda system.
How to connect the LC-2 to a differential ECU input without errors? How to fool the ECU to not showing error when heater will be disconnected? (dummy load only?)
The 1-lambda maps and 2-lambda maps require different XDF's. The data offsets are completely different between the two types of map.
