Thank you so much guys, I'll try with your suggestions.
I'm working on my 370z ECM and my car is not running since november... I've bought more than 8 ECMs, my mechanic stays in another town (60km from where I live), so it's been very hard to get it to work

and to make things even hard, I live in Brazil, so I need to shop through eBay and it take a looot of time to arrive it here. So I'm willing to pay anyone that would be able to help on this if I can't!
