Megasquirt is coming soon but i already have the LC-1 so im throwing that in tonight...do i need to reprogram the analog outputs if i tie the brown wire directly into the stock 02 sensor wire WITH THE STOCK ECU...then do i need to RE-program it for megasquirt?

Thanks, Brian

Also, i temporarily hooked up a narrowband gauge to the yellow analog output and it was saying it was running as rich as it could is this a problem or do i need to re=program that output also (it was an autometer sport-comp gauge)

 

nobody knows what voltage the stock ECU sees?

 

So i set it to NB and went for a test drive....NO POWER AT ALL..until it hits between 3 and 4K....should i try switching to WB?

 

Im confused by your question in all honesty. But I will just throw this out there, I was discussing this with arkmage and he says that if you want your LC1 to emulate a narrow band sensor to output to your ECU then you need to put a resistor in the line to emulate the cars factory heated o2 sensor.

Something like that.

 

Basically...my MSPNP should be here soon, so i decided to go ahead and get one part of the install out of the way now..the LC-1...i have the Brown wire plugged into the stock o2 siganl wire (behind the coil)...no i have no power at light throttle or below about 3K...what voltage should i have the analog output that im using set to?

 

.45v I think

I could be wrong. Im a total noob, and all the reading and question asking I have been doing has been giving me a headache, this stuff is not simple.

 

So to get this straight... you want to simulate narrowband on both analog outputs right? One to your stock ECU, and one to your narrowband o2 gauge thingy? The manual covers this more or less-- page 4 at http://www.innovatemotorsports.com/s...C-1_Manual.pdf tells you what the defaults are on the outputs. Analog output 1 (yellow) is setup to simulate a narrowband from the factory. Analog output 2 (brown) is a wideband output, but if you want you can reprogram it with the same settings as analog output 1 and it will simulate a narrowband also. Then you can run one to you stock ECU, and one to your narrowband gauge.

Then when your MSPNP is installed you can pick one of those outputs and wire it to your MSPNP, and reprogram it back for wideband usage. When you do that check out our FAQ at DIYAutoTune.com for the recommended config. I won't bog down this thread with that info when it's in there.

Check the Innovate LC-1 manual for the info you need to setup both outputs to narrowband sim-- the specs are on page 4 at the link above, and you'll use the LM Programmer software to set it. It's pretty straightforward.

 

i know HOW to reprogram the LC-1...i need to know WHAT to reprogram it to...i've tried using both standard settings now (basically tried the yellow and brown wires) and i have basically NO power until 3 - 4K RPM...so are my outputs wrong or do i have another problem?

 

Did you look at the manual, page 4, that I linked to above? That's why I linked to it-- it tells you what to program it to for narrowband sim.

 

It's 4k, its when the stock ECU switches from closed loop to open loop. Your LC-1 has the wrong output settings, read what Jerry posted and adjust your LC1 settings.
