  How did I fry my ecu 2:22 PM 7/18/2008

Thursday I installed an afc neo and it worked fine with the stock Maf which was bad .Then I installed the z32 Maf and as soon as I did that and turned the key it fried my ecu.The wierd part is that inside the ecu where it fried was pin 55 Ambient Air Temp Sensor and also theres a mystery wire for pin 17 Injector Pulse Duty Output (Trip Computer For Fuel Usage Meas.) which is just hanging now and I dont have a clue where it goes and I have my friend an sr20 guy hanging over my shoulder laughing at my pos thanks for ur reply.

Wrong connections will cause this nearly everytime.

Who's selling their CA18 next ?
Forged pistons are no insurance for ignorance .
Spending money foolishly doesn't equate to a high hp car .
Being cheap all the time equates to a waste of time

But I dont understand what I did wrong because I followed the write ups word for word.Is there any kind of way I can trace down the bad connections?

I fried the same input on my ECU 3 years ago. Never quite understood what happened because it ran fine one day, went to go to work the next morning and it fried. Replaced it with a MINE's tuned ECU and has run great ever since.
