LM-1 is installed
Christams has came on gone but I just got the time to install my LM-1. I read that the A/F should be between 12.45-13.2 for best power. I thought 12.9-13.2 was the best. What is everyone setting the A/F for?

Good to see you have it installed....you should run down the track and see what it reads at speed

I still need to hook op the tach wire, theTPS when I find out what color wire I need to use coming off the tps and what else can i hook up to the rpm convertor.

use one of the coil ground wires for tack. one of the same ones you use for the air shifter. Bossman give me a call tomorrow.

Will do Ninja12, I hook up the TPS Y/H wire(thanks Karl) but now have to convert the volts to % and do the 2000rpm tach setting. I did use the wire off the #1 coil for the signal.

boss
for tps the table that gets it close for me is
tps volts
-33 0
127 5
it doesn't come out perfect but very close: at zero throttle it reads .2%
at WOT it reads 100.3% or something like that.
my company wiped out my laptop (idiots), so i had to reinstall the LM-1 SW and now i am starting almost from scratch setting up 
and for some damn reason my tach signal is noisy again (i fixed this once before), so tomorrow i'll get after it.

Thanks, now my battery is low on the bike and it will not start. I need that red jumper cable that hooks up to the pos side of the battery. So I can jump it off when it gets low.

Ok, I got a jumper cable for the battery. Started the bike but now tach signal. I tapped into the black wire off the #1 coil and I am getting volts to the rpm converter but no red light. Should the light light be on all the time?

Bossman,
I borrowed JC's new LM-1 and I couldn't get my rpm box light to come on until i fiddled with it. I'm not even exactly sure what i did right but it finally did come on:
1. Did the set up in Lm Programmer section 5.1 w/audio signal and the led came on. (not sure what i did right)
2. Did the section 5.2 auto config at 4000,
3. then set the rpm x 2 (in LM1 Log, configure rpm) and it reads right.
go figure.

Thanks, I get a light when it has the audio signal hooked up. But not with the motor running until I put pressure on top of the rpm convertor. Then the light goes out if their is no pressure so I sent it back.

Good luck getting the RPM converter to read correctly. Could not get mine to work. LM-1 people said my ignition probably has a bad ground. All the grounds seem to be perfect though! I am thinking maybe there is a short in one of the ignition wires somewhere causing the interference. I do think that the RPM converter could of been designed a little better though. My Dyna shift light, & dynojet PC3R have no problem getting the correct RPM's! The sniffer part works great though. Without the RPM readout though, you can only adjust the idle mixture. Everywhere else is just guessing!

addison,
where did you ground the rpm box???
I got a noisy signal when I grounded to the frame, but not when i used a sensor ground outa the ECU.
The rpm shown by the lm-1 matches my Fluke pretty close

What do you mean you got a noisy signal from a frame ground.? How can you tell that?

when i first hooked up my rpm box i grounded it to the frame. the signal was jittery. I then changed the gnd outa the ECU which is also used for the airbox temp; the jittery signal got smooth. it still has spikes/data drop outs at low rpm, but at high revs it looks pretty good
sept 04 - changed rpm box gnd from frame to ECU pin #60, got clean rpm signal

So you mean the volts where going up and down and the tach needle on the programer was not reading steady.

Entropy, I did try the ECU. Nothing, & the frame. I even tried grounding it to the same place the pc3r is grounded, nothing. What is interesting with mine is the rpm light goes OUT when I plug in the power plug. Found that out by accident, as the LM-1 will register RPM on the display if you unplug the 12v power plug(will run off the 9v battery). Power plug in, no LED light. Power plug out, LED light goes back on. That's why the LM-1 engineer suspects a bad ground to the ignition. Kind of a pain in the ass to work with too, cause the bike has to be running while I am trying to get a signal, & it runs a little hot just sitting there idling.

i look at the line on the graph more than the display (mock up tach). At idle, the graph is not a nice smooth line, but at 3000 and up its pretty smooth.

huh?????
You are way more into it than me, i don't know anything about grounding the ignition; is the lm-1 engineer being helpful?

Entropy,
The LM-1 people tried to help, but being it's a zx12 they have no actual experience with the 12. Just diagnosing in general from the symptoms. Their main expertise is the car world. I don't know if I will ever get it to work properly. Being I had the engine out a few times, there is a chance I have a pinched or have a open wire somewhere in the harness. Electrical gremlins can be hard to find!
