I just got my ECU flashed and got it back today. I put it back in the car and now the car doesn't start. It sounds like not gas at all is going in. It's not even rough idle. Has anyone come accross this problem. This sucks. My car's been down a week now and now I have to call them and find out the problem. I'm hoping one of you can tell me if I"m missing something.

 

first off, call giac. you bought their software, they need to back it up with support.

 

^This. A brand new software tune that you paid a lot of money for is not something you need to be trouble shooting yourself. Call GIAC and get them to help you fix it.

 

For starters, did you let the throttle body align itself? Any time the ECU is powered off (disconnecting battery, unplugging ECU) you should let the throttle body perform its alignment.

 

it will still fire without a tb alignment though. im sure youve witnessed that. it just sputters and wont idle. the car not firing at all is a larger issue.

 

All good. Called AWE. Car didn't fire at all and was as if there was no spark. Basic procedure that got it going is, disconnect bat-, wait 5 min, connect bat-, Turn key to ign, wait two min. At this time there will be a crackle with a high freq hum wait until it stops then start the car. That is the throttle body going through it's recalibration

 

Also known as a throttle body alignment. So, I was right that this fixed your problem?

 

Looks that way, but i also think its weird it wouldnt even fire. My car just ran like ***.

 

It's running bad? Did you make sure you haven't boost leak whatsoever?

Also did you replace your DV?

 

well i just sent my ecu out ones i get it i well tell you if it does the same lol. hope not.. did you even make sure the car ran ok before?
