Has anyone used any of their products?
They appear to be well beyond anything else for value for money. Their products are sold on AEM Wolf4D website and also mentioned on Adaptronic's website.

Very good product for a small amount of money.

Can recommend this, even if I sell and use Plx products myself.

Yes they are the best value/$$$ you will ever find.

Despite what autronic claim you can use them with the Autronic ECU, although some signal modification is required.

I use a 2CO with my Autronic SM4 and it seems to work fine.

KDog, is the signal modification you refer to remapping the output to give 0-5V from 10-30:1 AFR?

A friend of mine got an Innovate LC1 (with sensor) delivered in Perth for about $270. This was about $200 less than I paid for my techedge IIRC.

They look like pretty good value.

ive got a tech edge wide band installed in my lincoln mark VIII right now, running 9 lbs of boost, this is the 5th vehicle ive had it in. very happy with it, have to drive something while i work on the sc build!

Yes,
The Autronic ECU wants to see a 10:1 - 30:1 A/F ratio over a linear 0-1Volt range. (The SM4 can also be configured to use 0 -5 volt input so its a bit easier to use) For the older sm2 and smc ecu's do the following.

1) Set the range of the techedge output to 10:1 - 20:1 A/F ratio over a voltage range of 0-5Volts.

2) Use two resistors to divide the voltage seen by the Autronic by 10 (2Kohm and 18K ohm resistors). So The Autronic is seeing a range of 10:1 - 20:1 over voltage range 0 - 0.5 volt.

Normally the Autronic meter would give the full range of 10:1 = 0 volt input, 20:1 = 0.5 volt and 30:1 = 1volt input.

The techdge only does up to 20:1 A/F ratio, this isn't a problem as no one would run this lean and the extra range of 0.5volts -1volt range input is essentially wasted.

You do need to be carefull how you configure the grounding output of the techedge. Use the floating ground output method so that the Autronic ECU is providing the ground. This way there are no offset voltage errors.

Hope this makes sense.

Kdog, will this make the wb output accurate enough to use the autotune feature?

It sounds a little unstable when its only 0,5 volts from 10-20 afr.

 

[KDog]

Its exactly the same voltage levels as what the Autronic analyser puts out. Hence why the techedge will work with the autronic ECUs.

There is nothing unstable about it. 500mV is plenty of signal, I wish everything I worked with had voltage levels that high!!!!!!!

Setup up the grounding outuput of the techedge correctly and there will be no problems.

I have a Tech edge 2A1 diy. I haven't done much tuning with it yet but I'm very happy with it. I believe it is the best value for money WBO2, particully the diy version. you can also buy it directly from the tech edge web site and they arrive next day with in Australia. Peter is always willing to give advise over email.

I currently have it fitted to my sprint boat with a Map sensor and G sensor to have a play with it next weekend at a practice weekend. I also discovered that you can modify the log files to work with Innovate Motorsport's Logworks 2 software.

Andrew if you make it down to the Gold Coast to look at my boat I can show you my WBO2.

Cheers

Daniel.

Techedge with an Autronic

Yes,
The Autronic ECU wants to see a 10:1 - 30:1 A/F ratio over a linear 0-1Volt range. (The SM4 can also be configured to use 0 -5 volt input so its a bit easier to use) For the older sm2 and smc ecu's do the following.

Hope this makes sense.

My Techedge unit has been reconfigured (in the software) so that it outputs a 0-1volt signal instead of the 0-5 volt signal to work with the EMS 8860 ecu, so no reason why it can't be setup the same for the Autronic to directly give it the signal it's expecting?
