The LM-2 has a direct tach signal input signal.
This input can be used to feed a signal from the negative lead of a coil, ECU, negative lead of an injector, or ignition box (i.e. MSD 6AL).
This tach signal can be feed to the RPM + (Black/White) wire.
The negative wire (Blue) can be connected to ground if a tach signal is not being registered.

If you guys could care less about this I'll stop with the techie posts

Good stuff, thanks for sharing... Hopefully someone will pop in with that last answer for you..

Off to have a beer! Good times in the garage today.

So easy to do with this software... That sounds like something i would try...

My questions today...what is the second TPS...one for each throttle body?

Michhub, I've been through the Tach and 4ch logging the hard way, hardwired, with an LM data cable over in this thread

how I hooked it up

I took the Tach right off the ECU and it was a Frequency Modulated signal that the Innovate data cable special Tach input was able to sync on. Worked great.

Tach signal looks like this on a scope, cycling the key and the tach going through it's diagnostics sweep on startup.

TuneECU quick update for y'all:

Bike: 2010 990A
Tune: KM601US0902002.hex for 2010 990R
Mods: Football secondary butterflies, 2 into 1 w/Wings NOS can+large baffle, Rekluse and throttle tamer.
TuneECU Options: no SAI, no 02 sensors
Gearing 16/45
Temp: 74* F
Application: 15 min idle trick

Very smooth partial throttle openings, smooth from closed to open and very easy to do 1st gear left turn/right turn tight circles. No lean stuttering at steady state throttle in 1st or 2nd gear at 4k rpms. Nice gurgle, no exhaust pops when chopping the throttle on decel.

I just got done burping the coolant system AGAIN after some motor fiddling with the clutch basket and my rekluse. The motor was running nice and cool and I think it's partially due to our low temps and the WW I have in the rad.

I've tried the latest Akro map I can find and it's not smooth off idle or very small throttle openings, so I backed it off and applied the 2010 990R map that got me 40+ mpg last time I ran it.

EDIT: Forgot to add the throttle tamer and Rekluse clutch and the 2 into 1 from CJ and the Wings can...

test and tests

1 990 R 7600KM
2Nd 990R 7200km

1st map akra R, leo vince 2 1
2nd original map, then map akra, then map Otto (pp. tuneecu)

in all the accelerations a plus of difference for the 1st bike, started at 3000 rpm in 2,3,4,5,6
the moto 1 takes advantage of 30 meters or more

After loading the maps the reset of 15 minutes.

both with
Removed O2
Removed SAS
2 removed Accelerator
same weight of rider

where this difference?

Are you sure both run 16 front and 42 rear sprockets?

If Mr both series

Starting to hardwire the LM-2....


TPS is in the main harness thats gonna be harder to tap...

Tach signal was pretty easy to get to....

[gefr]

KM601AK0704501 is AKRA US 2007-8 is identical with
KM601AK0702S01 is AKRA EU 2007-8

Also
KM601AK0704501 which is AKRA 2007-8 (see above) at TPS5%
seems to be close to 5% richer than the KM601EU0704501 EU normal exausts.

I am going to attempt to mod my 2007 990's mapping. I m not the best on computers but can't live with my bike current mapping. I had the Akro map loaded and it runs slight bit better but is getting 25 to 30 mpg and stalled 3 times yesterday around idle with the wife on back. I was looking for someone in the Cleveland, Ohio area that has experience with loading maps and tweaking that could help? Anyone out there?

[Michhub]

Out with the old sensor...

In with the new...


Uh oh....notice any difference between the two...new Bosch is fatter and it won't screw into the factory bung
...and I see why, factory didn't quite lineup the bung and welded it off center

Dremel to the rescue a few short minutes later all better...I didn't want a bunch of metal
particles in the exhaust so I used a magnet to get as much I could...

Route the cable...kinda tricky as it has a large connector on the end...

Glove box wiring complete ready to log some wide band data, Tach & TPS


Here's to using TuneECU to make my own custom map
