did you unplug your ignitor during install?

yes.

:mad:

is there an easy way to turn off enrichments...because for some reason autotune refuses to cooperate.

The autotune won't work unless you make some tweaks to the code. The VE Analyzer in MegaTune works well. Enrichments won't affect it.

Did you adjust your custom.ini file?

thanks, but still sys I'm out of range, or 0%. I've obviously fucked this shit up. autotune would be nice, but I'm just going to tune by hand now.

i think the lc-1 is still fucked up considering I have AFR's out of the voltage range I set up in the controller:

Change your MS settings in the configurator.
I'd be more worried about your RPM readings than the WB readings.

HAHA, rpms are off the charts. Must be all that sugar in your tank :greddy:

yeah, I don't know why this shit is all crazy in the loggr. They read fine on the dashboard.

it is a miata.

okok, will autotune still work if my open loop settng menu says to go open loop at 53kpa? I should change it to 101kpa, or 0 like it says in that window for autotune...right?

did everyone else go through shit like this?

trying this tomorrow:

I started out with the EGO correction limit set to 15% and the step size at 1, and it helped me to quickly get a rough tune achieved. I only did this at about 75 kPa and below. Next, I set the EGO correction limit to 10% and did the top end, and I then set it to 5% for my commute for the next few days to trim things in a bit more.

I did notice some oscillation with the limit at 15%, and even a bit at 10%, but that may have been due to my changing the "x radius limit" (distance in RPM from the nearest vertex) from the default value of 200 to 350, as I was getting too many "not near a vertex" messages and wanted to get it tuned more quickly. Besides the window limits, all other parameters were the default values.

One thing that did stump me for a while was the "change EGO limit with MAP" setting. In the 029V2 distribution, the default values for the MAP value and the EGO limit are both zero, which means that at any MAP value above zero the EGO limit is 0%, i.e. closed loop control is disabled. Once I put two and two together and realized the function of this feature, I set it at 80 kPa and 5% to limit the top portion of the VE table when I had the overall correction limit at 15%.

Great feature! Thanks, Eric!

The autotune sucks balls. VE Anaylzer is the way to go.
No clue on the RPM situation. How did you take the log, on your computer, or on a Palm?

on a computer. I'll play with ve analyzer tonight before I get on the plane. Is there a writeup on using the ve analyzer...I can't seem to find much with google.

I can't get my MS dashboard to show any lc-1 signal. I changed my grounds to the same point on the throttle body...but can't seem to find the ground from the ecm there. I did another free air calibration hooked it up, and still get nothing. I changed the configurator how according to DIY's manual.

Kinda stuck here.

Thanks

edit: going to garage armed with multimeter.

The Log Viewer will read voltage from the log and convert it to AFR, so make sure it's set up for the Innovate 0-5 rather than LC-1 default. Also, could you post your MSQ?

It is set at 0-5. I'll post the MSQ when I get home from work.

Thanks so much for the help. Sorry to be an annoying customer.

does anyone have any thoughts on why the MS is set to "lc-1 default," the lc-1 controller is set to 0-5 : 10-20 for both outputs...and I'm getting super rich 7.0AFR readings in MS? Also, to make things worse the LC-1 is showing 6volts at idle. I'm thouroughly confused.

This is why I'm stuck. It makes no sense to me.

you don't use lc1 default, you use lc1 0-5V linear

Can you elaborate on VE Analyzer, is it part of Megatune?

I was going to scream profanity, but I'll wait until I get home to check this.

Then select LAMBDA_SENSOR. You will see a menu of aftermarket wideband controllers at the right. Select the one that corresponds to the controller you will use. The LM-1 default will use the INNOVATE_1_2_LINEAR if you are using its default volt meter settings, while the LC-1 will use the INNOVATE_LC1_DEFAULT settings if you have not changed its outputs. Note that the Innovate products and many others have programmable outputs, and these options are simply for the default configuration. Adjusting the LM1 to use a wider range of output voltages, such as setting it to give 0 volts at 10:1 AFR and 5 volts at 20:1 AFR, will reduce the effects of noise in the input. This is recommended for best performance though you will need to program your LC-1 or LM-1 outputs to match, that’s easy though. Once you have specified the wideband settings, go to the File menu and select Save. Then you can run MegaTune and have it display the correct air-fuel ratio.

It never occured to me that the lm-1 used a linear output. At least I can claim this mistake is counter-intuitive with a lack of simple instructor for fucktards like myself.
