Ostrich 2.0 Prblems

[eutu1960]

With the ostrich 2.0 hooked up the engine runs very rough and will cut in and out
at idle and intermittent engine light, engine seems to run fine with just a chip
installed, I am using it with a 7727 ecm. I have been only plugging it into my android device when
I need to make a change. does it need to be plugged in all the time when the motor is running.

Either the Ostrich needs to be installed, or, the eeprom it's emulating has to be plugged in.

If neither are plugged in, you will see exactly what you are getting.

I run my Ostrich with no USB connection most of the time, no issue... The Ostrich can be used in an E/EPROM replacement way.

I do however have one Ostrich, that through possibly something that I did in maybe possibly using the ECM case as a ground for something possibly while testing seems to need to be plugged in otherwise the ECM doesn't read from it. That reminds me I need to contact Moates about getting it repaired...

It does sound like the ECM is not correctly reading the bin file stored on the Ostrich though. When you plug it into a device does the poor running go away, or do it still remain?

I read the original post, but apparently by the time I got to the end of your post, I must have forgotten that you indicated that you actually had the Ostrich plugged in and still had your issues.

My bad.

I'm confused now by reading your question again.

You started off by stating that with the Ostrich plugged in, you have issues, but everything is good with the chip in.

Then you state that you only plug the ostrich in when you make a change and it's connected to the android.

I don't know, but Six_Shooter might, does that ECM require a Checksum disable?

If your engine is running poorly and the check engine light is intermittent, what then are you changing?

[eutu1960]

When I have time I will have to try it with my android plugged in and disconnected, so far the only changes I have made was to idle and timing at idle and different bins.
If I burn a bin to a chip it will run fine just off the chip. I may wait until I get a laptop that runs windows so I can use tunerpro RT, I like using aldldroid for data logging
but so far not for making changes using the ostrich.

[eutu1960]

OK I finally got a win 10 tablet to run Tuner Pro RT, I am still having the same problem so I contacted
moates support and he is saying that I either have a bad bin or a checksum issue I asked how I could check for a checksum issue and said that the mask id has to be $AA hex not $8D hex. I am not sure what that means being new to this so if any one is able to inform me please do.

sorry for the late reply with the ostrich plugged in or not the car seems like it is running in limp home mode will barley idle etc. only changes are idle, fans, etc.

As far as I know, the only time you change the checksum to AA is when you are using the Ostrich in emulation mode.

Now I'm not so sure about burning a chip whether that makes a difference. To be on the safe side, when you burn a chip, you can just change the checksum back to what it originally was.
