Hi Jerek,
Conserning the AN fittings, another option to consider is to use JIC fittings, they are readily available from any Hose and Hydraulic type shop that does commercial and industrial hydraulic system repair, they are only available in steel and are cadmium plated (that goldish color), but use the same 37* degree seating surface that the AN aluminum and steel fitting use, but without the expense...

Thats useful info!!!! Lets hit the hydraulic shop :)

dude yeah!..... come on o2!! so the new software is going to have datalogging??? probably your version :p

Michael Smith 04-03-06 03:14 PM

Hey !!! Jerek10, no one has come clean with a O2 map but I have a idea.
Step 1 turn on your car without starting and wait until the o2 voltage is steady record this voltage(car cold left over night)
Step 2
start you car get it hot go for a drive on the open road for about 5 minutes. Not hard but enough to get a good heat soak in the exhaust. Idle the car down and then turn it off. Then turn the ignition back on(don't start it) and then start reading the O2 voltage until it is stable.
Step 3
Save your current fuel MAP
Step4
Modify your 42% and 50% load points across the rpm range adding more fuel. Now driving the car and increasing fuel you will get to a point where the car will bog or go very flat when you go WOT in top gear. When you get to that point write down the fuel you are injecting at 42 and 50% (from the map)the staging for both, the injector sizes for primary and secondry and the O2 voltage displayed on the handset when it bogs or goes flat. Don't worry if you have heaps of black smoke for the moment.
Step 5
reload your good map and take it for a drive to cleanup any remaining carbon don't flog it.
Step 6
Send me the info please.
Step 7
After some time I will put together a rough O2 map as a guide and make a new O2 cal file to send to you.
Cheers

Where can I get an LSM11 sent to Perth from? And how much should I be paying?

I paid $311 plus freight from Wolf in Melbourne. Also the AFR isn't displayed on the laptop only on the handset ok! I think if I was going to do it again I would go for a techedge and write a different logger to read 2 com ports also some of these wideband can emulate a lsm11.
Now they are also more expensive overall about $450 up.

When I finish the auto tuner it will use only voltage to adjust the fuel injection pulse width. The AFR is for the tuner to work out, it will tune from rich down to the target voltage. The lsm readout is very rough 2mv and make accurate AFR's near 14\.0 to 11.1 very hard to achieve. Now if you have a programmable wideband over 5 volts you would have more accurate tuning.

I will be waiting for the new software to come out first. I have seen the lsm11 on www.wb02.com for $260

So even with the new software you don't think it'll be accurate enough? I emailed a guy over here that tunes wolfs and he rekons the lsm11 is whats used in a lot of dynos including his and that it reads the same as the handcontroller.

The handset is accurate the readings to the laptop is in 2 mV steps this is too large for real accurate tuning. It needs to be as low as 0.1 mv between 13.0-11.1. As far as I can tell the new software will not be able to address this problem. The only way is to make a interface that plugs into the handset port and decodes the data!!!

Oh and I ment to add that it doesn't only use voltage it also uses the current from the O2 sensor as well thats why you can have 0.02 volts and 14.1 afr this is why it is important to have your sensor hot before logging. This is why a mechanical/electronic interface from the handset port would be better than the PC port on the wolf..

I have and Innovate LM-1 wideband. If I send the LM1´s analog output to the Wolf O2 sensor input will I be able to get good results for datalogging?

Michael Smith 06-14-06 06:08 AM

Yes with a custom calibration table. If you set up your LM1 so that AFR of 20 = 0 and AFR of 10 = 5 Volts this would enable accurate tracking if used on the wideband input. The accuracy of the Wolf is in 2mv steps sent to the laptop port. but you have heaps of 2 mv steps between 0 and 5 Volts.

If you have a look at a calibraition table in the Wolf logger table us shoulb be able to work out what you need to do .... or I could make a Custom Calibration File for you.

P>S> PM me :)

pilot 06-14-06 05:37 PM

I guess I´m in trouble then, my Wolf is firmware 4.56 and it doesn´t have wideband input... :(

Can I send a signal to the narrowband input?

Michael Smith 06-15-06 04:34 AM

Are you sure ???

pilot 06-15-06 04:39 AM

Steve from AEM said that if it doesn´t have a label specifically saying that it is "wideband enabled" it doesn´t have.

Even so, I have been checking the old software and it has a 0-5v calibration table for AFR in "Oxygen 1" sensor. I guess that is the narrowband input?

Michael Smith 06-15-06 06:00 AM

I mine is 4.56 with wideband it had a sticker on the bottom. Thats why I asked.
The output of the narrow band can still be used I would suspect. The AFR display would be wrong on the handset. However if it tracks voltage, well you should be able to use the Autotuner and Wolf Logger as they read Voltage and converts that to a AFR for the program display. The wide band may not work on the narrow band input you need to ask Steve Taylor. Now I can't see why it wouldn't work with the Wide band anyway but I didn't build the ECU and Steve would know for sure. I know that on the wideband models that if you connect the wideband to the narrow band input it can lockup.

pilot 06-19-06 03:33 PM

I have asked Steve. I´m waiting for his answer.

Hi George,
All of our Plugin ECU's do not have wideband
facility. I am sorry if you thought that they did.

I would recommend buying an Innovate Motorsport LM-1
meter. They are very well priced.

If you like, you could email me your map, and I can
have a quick look at it too.

Regards,

Steve..

^^^^ :(:(:(:(^^^^

LC1, is a solution... with a narrow band simulator....
