I added the data xml to evoscan. What do I need to check in order to log the data?

It's in the "Important ECU Thread Links" stickied at the stop of EcuFlash forum.

 

does prosport have a 0-5v analog output?

 

Yes it does (and a 0-1 output as well).

 

I did everything that thread said to do and I see a few different Wideband AFR's I can check to log (AEM, LC-1, etc). Just need to know what it shows up as in Evoscan. I'll double check the thread. Thanks.

 

did you come up with the formula already?

 

The one I'm using is: 2*(0.01953*X)+10.5

To be honest I found a local tuner I trust after having some law enforcement issues email tuning, lol. He has his own wideband he plugs in so I haven't had to worry about it but after he's done I will get back to making it work.

 

I have my prosport connected to the rear input, followed: https://www.evolutionm.net/forums/ec...ial-cable.html

I tried different formulas in evoscan, the correct one (in theory) should be: 0,03921*x+10, since it displays values from 10 to 20, and should be correct with the table relating volts to AFR, but after some logging and comparing what evoscan was displaying and the gauge itself, they were a little off (1 to 1,5 afr points difference)

Now I'm using the formula: 0,05859*x+7,7, when in boost at WOT, seems to be the same between the evoscan screen and the gauge (kind of hard to look at both at the same time and compare). when I lift off it goes lean to 22+ which the gauge shouldn't read, and when the tune was really rich it showed 9,8 which is also out of the parameters. But WOT, idle and cruising, I like it better than the previous formula, is much closer or almost the same as what the gauge itself displays.

Hope it helps

And some people say prosport is garbage, but I had a AEM installed (borrowed) for a week before I received the prosport, and the idle and WOT was really close, almost the same values. Then I started tuning so everything changed. The sensor is a bosch unit, different model than others (4,9 vs 4,2), but should be good too. I really like the prosport gauges, so I have no plan on changing them

 

Recently, I compared prosport AFR gauge with my innovate LC1 and I have noticed 0,3 AFR points difference between the two units.
So we can say that prosport AFR gauge is ok for serious tune.

Interested in this formula

 

And now I need this. I will try this weekend. Thanks. I'll report back.

 

Keeping an eye on this thread, I bought a prosport gauge without thinking about the ecuflash benefits of aem lol. So thanks for all the info on this so far.

 

I haven't driven the car yet but I think the gauge is not pinned right (Had a shop do it for me that was doing a ton of other things. The value is ALL WRONG. Its shows 41077 when the gauge is showing max lean (while the car is off).

I expected it to at least show me 20-22
