Has anyone done this yet?

Good question! A related question is: Which cylinder is affected by the CylOffs table? I would think it's cylinder 2.

What I do know is that the sensor pin most far away from the large connector (i.e. the one with R12 as opposed to R12b) is sensor 1.

Question remains, which of them is cylinder 1? I think it's the LH cylinder on a Guzzi, or the front cylinder on a Ducati but chances are I'm wrong on one or both Huh

All good questions. Unfortunately I don't know off hand.

For the original question, I think this a way to find out, make sure your initial setup up can be swapped around easily.

Make sure map is set to allow tracking at idle - 0,1 cell.
Have one input connected properly and ground the other. If correct you should see one voltage tracking the set voltage ( near constant correction) while the other side you will see the % correction diverge from 0.

If wrong I think you will see both diverge from 0%

Reply #4 - 08/24/10 at 13:38:07 I have both LC-1 O2 sensors installed, and Logworks3 shows both are working. I set the ECU switch for O2, and set inputs to both. The saved map shows that the inputs are in fact set to both. ECUController only shows one O2 sensor, so I'm not sure how to proceed.

I've never got around to adding 2 to the ECUController. The Optimiser will display 2 if you have that. The ECUController should log both though.

Two questions:
When I have the Optimiser plugged in, the Rpms go to ~2500 and show 0,5 while TPS is still at idle (137) and the bike's tacho is showing ~1100 RPM.
If AFR=7.35 at 0 and 22.1=5 volts, shouldn't the O2 Targets in the My16M Configuration be negative voltages?
One more thing, in Autotune on the Optimiser, I periodically get a message on the bottom line showing some numbers followed by -> or => and more numbers. It happens so fast I can't read the whole line. Does anyone know what that is?

Do you have the normal tacho (dip switch 3 set to on) or the TPS/tacho display? I don't think I understand your first question.

Targets should be negative, yes. But it won't show up as negative except in the settings menu.

That message is telling you Autotune changed a cell. I don't remember off hand how it looks, It's something like coordinate and amount.

Dip Sw3 is on, 1,2, and 4 are off. On the Optimiser it shows:
t137 r2500 approximately, but the bike's tacho says 1100, and the engine is obviously running faster than 1100. If I unplug the Optimiser, the engine idles normally at about 1100. What do you mean by the Settings Menu? Do they show up as negative in the map file? I just checked a map file from yesterday, and it shows:
MyECU Cfg O2=0.00V,-3.00V,-2.75V,-2.40V,-2.25V,-2.00V,-1.75V,-1.50V,

Reply #9 - 08/25/10 at 08:51:43 The Optimiser being connected or not should never affect how the engine runs. I have no idea what's going on. The target voltages should show negative everywhere they can be seen. But when the sensor voltage is shown in the Optimiser, it's not negative. Sorry if I'm just adding confusion

What you said makes sense. I will recheck what it says when I am running ECUController. From what I have seen so far, evidently the Optimiser is occasionally making some corrections somewhere in the map. What I'm having a hard time with is the discrepancy between the bike's tacho and the rxxxx reading on the Optimiser.

Reply #11 - 08/25/10 at 10:39:01 By the way, I have been taking pictures of my project. I will put in a link when I have them posted somewhere. Just so you know, the uname CONewbie is because I am a newbie from Central Oregon, where there are few, if any, MotoGuzzi owners.

Reply #12 - 08/25/10 at 13:22:28 If the tacho is alternating between good and bad every couple of seconds, you have the throttle/tacho feature enabled. SW3 on the ECU set to "on" will disable this.

I maybe wrong but T137 sounds a little high for idle ?
If its a V11 then I think somewhere between 95 and 105 is normal if the Std ECU TPS was set correctly ?
It may be the throttle is further open than it should be for idle but the mixture is off so the speed is slow until you attach the Optimiser and the closed loop values apply ?
You could see how it runs with my map, you may get a clue to whats going on ?

My map is still "work in progress" but its rideable

It's for a V11, Drilled Airbox (Std paper filter) Mistral X-over and M4 Cans with Db killers installed.
Hope its useful.

Code:

# TDC is the pulse count for TDC power stroke of cylinder 1 ( i.e. When the spark fires
# CylOffs is the number of degrees between success cylinders ( 0-720)
# PulsesPer is the number of pulses for the 720 degree 4 stroke cycle

MyECU Cfg TDC=0x1600, CylOffs=270, PulsesPer=48, MissingPulses=3

# CoilCharge is the period in us for charging the coils. 0 for cranking, 1 for running
# Warning, Setting coil charge too high can  cook the output transistors and coils

MyECU Cfg CoilCharge0=4000,CoilCharge1=2700

# Pressure - mV and mB values defines a line representing the air pressure conversion

MyECU Cfg Pressure=249mV,121mB,4751mV,1060mB

# There are 8 possible voltage targets available 0-7
# The first number for 0 should be 0.0 and means open loop
# For simple sensors where richer is more voltage, all numbers should be positive
# For later sensors where leaner is more voltage, all numbers should be negative

MyECU Cfg O2=0.00V,-2.25V,-2.15V,-2.05V,-1.96V,-1.86V,-1.76V,-1.66V,
MyECU Cfg 2ndO2Sensor=no

# RPM specifies the maximum RPM.
# TPS specifies the throttle value at idle (no fast idle).

MyECU Cfg RPM=8250, TPS=104

# TDCWhileCranking=1 will fire the spark at TDC
# TDCWhileCranking=0 will fire with advance from the map

MyECU Cfg TDCWhileCranking=0
