Interior 1st Gen Most liked posts in thread: Pros/Cons: ScangaugeII

Those are very cool It shows two Mini kit's, but when you go to the "application guide", Mini is not listed there? Do you know what it supports from the OBDll? Guess I could call them. Do you know if they have our amber color?

 

I don't know if they support 1st gen Mini's but for R56+ you need to email or call them.

They don't have amber either. The "red" one is what I chose but it's not even close to the Mini amber color.

 

Really? It was my understanding that even with the CAN bus for OBD II your updates weren't any faster than once per second as that is as fast as it can update. :confused5:

 

+1.........:confused5:

 

The guy who recommended the gauge to me had a mechanical boost gauge already and added the Aeroforce gauge. It updated just as fast if not faster than the mechanical gauge and reported the same readings. If it was updating once per second there would be a delay when showing boost. The other gauges you might not notice, but with boost you would. According to the guy at Aeroforce they update more often than once per second.

I don't have any equipment to measure the rate on the OBDII port.

 

I don't see how the gauge can update faster than the information it is given. The CAN bus only updates the displays once a second from the OBDII port.

 

The Bytetronik module, does data logging, which updates 10x per second. And that connection is to the OBDII.

 

??

 

It's accepting info from the ECU at ten samplings a second, so the the data must be generated if the Byteronik can read it. For what ever reason the MINI OBDII / Scangauge only wants to read one sampling a second.

 

Metalman, with FA53, we added some 'unique codes' into the ecu so it can spit out the BMW commands thru the OBD-II port. That's why the sample rates is so much higher via our data-logging b/c we are not reading the obd commands. We are reading the factory commands via the 'obd port' - that's the difference

 

Nice to have the key to the treasure chest.

 

The OBDII lag that MINI built in was also removed?

 

Nothing is done to the OBD II codes... those are intact... that's why the ecu can still communicate with scan tool / scan gauge / and diagnostic tools.

We deal with the original codes, which is a deeper layer.

 

Seeing as how fast the FA can download a new tune and as fast as the ECU excepts it....I could understand that the FA runs at a different speed.

 

Yep, that's where we increase the baud rate of the data transfer process. A typical flashing software would take 15 minutes to flash (most of you have seen this if you have been tuned previous), but with FA, it takes about 45 seconds.

sorry for throwing this off topic... back to the OP.

 

Exactly my thoughts as well. Does a Scangauge "watch" the CAN bus for data and report it when it's available or does it make requests for data at specific rates? I wonder if the Aeroforce is polling the bus and requesting data. In some cars (Chrystler) it can send commands to bus. I don't know how either system works so I'm just guessing here.

I'll check the data rate setting in the Aeroforce tomorrow and see how often it's looking for data. The manual mentions in certain vehicles setting this too fast causes delays as the car's system can't keep up. Makes it sound like it's making requests for data. There's no noticeable difference between the throttle and the boost display which wouldn't make sense if it's getting data at 1 second intervals. When I used a SGII with boost display the second delay was very noticeable.

 

The gauges are only recieving the data, they have no communication with the car at all. If the gauges are set to try and update faster than the car can supply then there CAN be some issues. The ScangaugeII manual also states this. But the gauge can only bo told when to look for the data, it can't ask it of the car.

 

Sorry to SNEEEZY - Erika for taking over your thread with this. I'll start a new thread next time I have an update.

Makes sense to me. With some cars, the AI gauge does communicate with the car. I sent a message to Aeroforce to find out what's going on here. I'll update in a new thread when I know more.
