Auto-tune function; how to implement?


Hi 4 all;



I installed the LC-1 to pen 12 in hayabusa gen-2 k8

The issue I got AFR 18 to 22 not less I try to use auto tune but I don't get any thing!!(ecu editor) regular interface.

I wish to modify the neutral plan because I wish to bypass the the clutch switch.

As start I subtract 6% from the fuel but no improvement. Noted that Fuel pressure is set to 42 psi.

1) do I need to disable the ABC toggle switch?
2) how I can implement the auto tune well? What parameter I am looking for?
3) Ignition map do I require to modify ?
4) ecu editor VS woolich racing which easy?
5) I am using it in my buggy what recommendations you can give me.


I really got confused I calibrated the LC-1 as the procedure but I didn't do any modification to oem setup since the brown is 0v to 5v.

Please advice; I will appreciate any help;

have you set the wideband up in editor or WRT and flashed to enable

bridged clutch switch will not allow the secondary injectors to run, your probably better off putting a momentary switch under the pedal or a pressure switch in line and get back full function

I would recommend connecting the LC1 to a laptop and looking at the output in the Innovate software to see how it compares in logworks while viewing real time.

Enable then flash to ecu and I double check and use the read to verify. I already put a pressure clutch switch (NC) in the fuild line. I wish if it can be bypass.

Sport biker; is there might that ecu editor have a issue so it read different. I can yes af gauge if it's only to verify.

Advice

There is always a chance that something is incorrect or there could be a voltage offset in the signal from the LC1. The reason I mentioned using Logworks to read the LC1 is that is is free to do so, just hook the LC1 to a computer. You can also see that the LC1 is functioning properly with the warmup cycle, etc when it is connected to the computer.

As Greg mentioned below, i reckon there is a good chance the Wideband O2 Advanced Setting has not been set, the stock sensor has a range of about 0-1.1v so the wideband O2 input above 1v would be registered as a very lean signal...

I will check the setting for LC-1 and noted that I do get low AFR at low rpm but when shifted to 2 gear. The AFR get high again.

When I decreases the fuel I saw it hits 20 AFR and some times 22 AFR

I don't know if this useful but I when I try to hold the throtle paddle in fix position it do weird things like trying to shutoff.

Some times I get F1 light on because of the ecu interface.

Sounds like you have some issues you have to sort before trying to tune the bike, what are the FI codes you are getting?

The F1 code only come when installing the ecu harness moreover the temp sets on the H. I put the ecu to neutral using the switch every things gone and come normal. I thought its the ecu harness behavior but while running normal there is no FI indication appear.


Before I start logging I switch to engine data.


I will attached the log file maybe it's usefull.
Moreover, I will inspect the STP sensor that might have an issue.

Have you blocked the PAir Holes off? If not it will show lean at the Lambda.

You clutch switch should be NO, closing when you press the clutch. I find the Goodridge banjo bolt switches work fine.

i have disable the pair valve and the clutch switch is NO and close when pressing clutch.

i use a brake switch through relay to make it normally open temporary.

 

is the issue here?? i am not using gm style sensor but i dont have any option to change it to stock.??

Moreover all data count shows zere? why? and in the previous post it shows that i do have data of less than 17.1 AFR

No that setting only applies for the boost auto tune map, i think the problem may be with the output from your wideband o2 controller or the wiring between the controller and the ecu or the wideband O2 setting not set in advanced settings?

The pin 12 is the W/G wire right?

Other wire kept open and isolated.


I will check the wiring and see if I miss something.

yup pin 12 on the gen 2 busa. Throw a multi meter on the 0-5v output to see what voltage you are getting as well, could be a problem with the wideband output.

Cheers

Is there a reason that you can't connect the LC1 to your computer and view the startup cycle and the serial AFR display on your computer? This is really imperative to troubleshooting an LC1 from my experience. Since you are not using the serial communications and have no display, you could have an LC1 that is not performing properly or that has not had free air calibration, etc.

All of the software to do so is provided free for download from Innovate.

I have chased many problems over the years and hav learned that any simple methods of confirming correct or reasonable operation can save hours of frustration.
