Tunerstudio going offline after starting engine
Hi, I have just finished wiring up microsquirt v3 on a zetec turbo, I am confident it is wired right. All the sensors read correctly. There is good fuel pressure, the injectors are firing and it's sparking. The problem is it runs horribly for a few seconds, high erratic idle and backfiring then tunerstudio goes offline and the car dies. Changing ve/spark maps and afterstart/warmup doesn't help the idle much. I thought it would at least try and stay running after it went offline. It never goes offline other than when it's running. I wasn't sure if this could be the serial/usb cable or something else. Any help is appreciated.

Re: Tunerstudio going offline after starting engine
Going offline when the engine is running is commonly due to a poor cable that allows noise in. However, with all the other symptoms you describe it could be other issues like controller resetting.
Without a proper information like a data log we will never know.

Ok, I will get a serial cable with an adapter and see if that helps first, if not I will try and work out how to post a datalog.
