Just a quick question.are you able to make changes to the ecu with ostrich 2.0 as the car is running?i wanna street tune my car and im not sure if I need to datalog to do this

 

Yes, you can make changes with the ostrich while the car is running, that is the point behind having such a device...

I would highly suggest hondata s300, neptune rtp or simular if you are trying to tune a vehicle your self on an obd1 ecu platform.
