Guys,
I'll give John the night off and throw this out to the group.
It's in and running, I still have a ways to go on tuning. I'm trying to get a process going to get it tuned right. Right now I can start and cruse around town at a reasonable pace and the A/F stays pretty much in the 14-15 range. I still have a ways to go on harder pulls. But any tips would be appreciated.

I'm having trouble getting my wide band to connect to the SMT6. I'm using the 0-2v lead and it doesn't want to read right. So, I'm logging in my head and using the narrowband output for data logging on the SMT6. Any suggestions? It's an Innovate LM1 WB.

Thanks,
Dan

PS for those wondering, the SMT6 is a piggyback fuel/ign computer similar to the ARCII (that it's replacing).

This is one of those things you're gonna need Vitesse for, IMO.

The wideband sensor is a 0-5v, right?
Coming out of the Innovate wideband, are you using the standard wideband or does it have a narrowband output feature?

Sam Lin

Innovate's output can be set to narrow or wide, whatever voltage range and whatever afr:voltage scaling you want.

DanD, if you haven't checked out Innovate's site recently, try out their new firmware and realtime monitoring/logging software. Still in beta, but tremendously powerful.

Yeah your going to need John on the WBO2 input, from a narrow band standpoint.

Are you running off of the start up map that he sent you? IIRC, jwl had to take a little fuel away at idle on his setup(Stage II kit) and then he went to Global settings and added fuel to the whole thing, but this was on a break in map after his complete refresh. One thing that John will want to know is the meter Vin and Vout when you data log. I know that jwl picked up his factory signal but he tuned the car using his WBO2 display.

Does this sensor have a chart on the website for voltage to perspective A/Fa ratio in narrow band; like 1.2v is 12.4 A/F ratio? If it does you can at least get a volt meter to see where you are on boost for the time being.

DanD

Thanks for the suggestions. John has been real helpful getting me to this point. My system is a hodg podge of equipment, so there isn't a Vitresse map that will plug in for me. I was hoping to find some kind of a game plan for tuning.

Like:
Sit in the garage and get the Idle and low speed settings close.
Cruse around at low speed and part throttle and data log for minor tweeks.
Do some low boost runs in 2nd gear..
and so on...

Something like that would be better than shooting in the dark..


For those curious...

John sent me the instructions for logging the LM1, but the readings don't match what the screen shows. I may have a bad cable, still checking. I'm checking the Innovate site... thanks Sam..

Dan, Is the Wideband voltage you are logging with the SMT6 a 0-2V or 0-5v? If 0-5v you can't log it using the O2 sensor SMT6 input, you will have to use a different sensor input.
I recall you mentionng that your Wideband sensor generates a 0-2V signal, however the translation of voltage to AFR may not be the same in the SMT6 as with your Wideband. Just look at the voltage vs. AFR.
With Wideband, you need to use common signal ground in order to read it correctly. I ordered a Innovative WB kit, will figure out the details when I get it.

DanD

Hey, you're supposed to be taking the night off playing with the kids.

Good thought on the translation aspect of the WB output. I haven't seen a chart that makes sense to me yet. If I can get on on the LM1, then I can just log the voltage and put it into a spreadsheet for translation to AFR. But, part of the beauty of the SMT6 is playback and seeing which cell is low or high on AFR. I may stick with my narrow band until I get it a bit closer, then fine tune it with the wide band when we get more details.

It's actually running pretty good with only a few hours of tuning.

"I ordered a Innovative WB..." I know you didn't do that for me, but hey, it's a nice to pretend....

It's a nice unit. I've already taken readings from 4 different cars using my homeade tailpipe probe.

DanD

Oh, it's 0-2v...

fast951

0-2V you can log it with the std. O2 input, however itight be a linear 0-2v signal and the AFR will be off. I'll email you a way to log it on a different sensor where you can set the AFR visually on the screen.
Do you have a graph on the voltage to AFR correlation from innovative?

DanD

I did use the 02 input, but it came out wrong.
I don't have the voltage to AFR cross reference.

Sam, do you have this? (or anyone else?)

Can't seem to get the 1.30 LM1 software to work, still shows up as ver 1.10
Still trying..

DanD

Hey, that logworks program looks interesting...



John, how's your montronic logger coming?

fast951

Dan, email me your phone #. Will call you later today and will walk you through it..
The Motronic Monitor is READY! Should be shipping within days...

DanD

John, sent you a note..

Sam, I have the 1.30 LM1 software working, but it still shows up as ver 1.10 firmware on the device.

DanD

Here is a screen shot showing the LM1 0-2v WideBand analog output.

I suspect that the SMT6 isn't ready to recieve that translation. I'll give it another shot today to get some more readings.

DanD

It makes more sense (to me) to see it in A/F settings.
