I'm thinking of getting an XD-1 kit for my car, wideband lambda + gauge.

however i'm curious as to if i can wire the LM-1 up to both my ECU and the gauge

my ecu support wideband lamda, so i wouldnt wnt to use the narrowband emulated bit of it, i'd want both the gauge AND the ecu to both get the wideband output.

is this possible? can you just run the signal wire to both devices, or does it cause the signal to be wrong?

 

not sure on the answer but im intrigued aswell.


out of interest jim what Ecu you going for?

 

i think the brown wire goes to your signal wire on your ecu

 

if both things have a high enough input resistance, then the output will not be significantly reduced.

generally, yes it can be done.

 

so it shold be ok just to split the signal wire then?

 

should be, but don't rely on it until you've tested it.

couldn't get hold of you on sunday evening jim. the number i had for you was wrong, and the second number just kept ringing. i'll try again sometime, busy for a while now.

 

i've PM'd you my numbers again

are you going to the PE rolling road day on sat?

 

oi moody answer my question

 

thanks jim, got it right now. damn dyslexia fucking tourettes got the bloody lot me

not available saturday sadly, would've been good and not too far away. thinking about it, i will be driving more or less right past so it could be possible. not sure i've got space in the boot though. i'll think about it and let you know by friday night.

 

melv, i've got an emerald K3 ecu

 

ah

ive got the data sheets on them from the autosport show on my desk at the mo. reckons 550+vat for the loom ecu software etc

have you played with the software at all?

 

Jim - I have one of these.

I may be wrong, so don't quote me on this, but I think you can use the kit to send info to two devices - ie the guage and your ECU.

This bit in the ad on ebay (if I'm reading correctly) seems to back this up:

It features the same industry-leading patented digital circuit found in the proven LM-1, and includes digital in & out, plus two programmable analogue outputs. The LC-1 can connect directly to the XD-1 for a standalone AFR gauge, and is ideal for using with an ECU

I don't think you need to 'spit' the signal so to speak - I think you can use one of those outputs or the digital out.

Of course I'm prob hopelessly wrong , but that's how I think it works.

sib, i THINK that means it has a wideband output (for gauge) and a narrowband output (for ECU) but i want wideband on both

 

that's not how that quote reads to me jim

 

Damn, I'm not sure either way. May be worth talking to whoever supplied it - I think GGR iirc sell these as well so may be able to help.

Me, I'm stuck now as I'm not using mine to be so clever as yours - mine is for tune up / diagnostics only. ECU is just a humble L8!

If you do find out let us know what the score is!

i'll RTFM when it turns up
