This is a simple enrichment of the mixture (5-6%) without risk for the engine. Reamp is the best solution , but in Italy is not easy and economy.For remap on dyno we cant spend 400-500 Euro --> 500-600$This solution is an economic step , for who has an sport air filter or exhaust whitout kat and/or dbkiller.
The Lambda signal is used by the ECU only in the so-called "closed loop" speeds, ie when the engine runs at a constant partialized speed, or at idle speed and surroundings. In the other driving conditions it is ignored to allow the enrichments necessary for the generation of torque and acceleration. This is the big limitation compared to what you get just with the modification of the IAT sensor, which is always active and effective even in transients (open loop), i.e. where you really need petrol when driving in the real world. The Lambda modification will give only an enrichment on the base injection and not on the others.https://secure.lambdapower.co.uk/TechNotes/Tech-3.asp
@GuzziOrDeath ..I am sure speaking with technicians and mechanics, however that Magneti Marelli injection in the warm-up phase, in deceleration, in full acceleration, above a certain speed, works in open loop.
Finebau, et al, have been making these gizmos for some time.
The Marelli learns from the past, it has a counter about how much is added or taken away from fuel. So when you add fuell, with making it to cold for the engine, the lambda will see that and note it. Next it starts taking fuel away because it knows it is to rich. A number of the carc stock maps are in open loop way to rich, I took away a lot of fuel in the higher revs, and only after doing wideband lambda testdrives. If you are sure to only want to add fuel, it's pretty easy, load the fuel map in Tunerpro, select it, and multiply with 1.06 for 6% extra fuel. Reading map, editing and writing back is done within half an hour. 0$But I like that you put so much thought in it. Do you know the Periscope from Giulio Buccini? Another Arduino project.
Maybe so, but we Fuel Injected Guzzi owners are lucky in that we don't need them.I can see how owners of other makes might be tempted, when getting their Bikes remapped costs several hundred £££/$$$/€€€, every time they want it done.We on the other hand, can do it for next to nothing, as often as we like.Plus with GuzziDiag, we can do all the regular Servicing functions, fault code checks and clearances, etc, instead of throwing money at dealers all the time.I guess until you've tried a Bike running a well-developed Map, you'll just never understand.Those of us that have, will just keep on enjoying the improved performance and Fuel economy, with huge stupid grins on our faces . . .
