I swapped the GReddy device out and I will wait to see whether they will warranty it or try to charge me to fix it. I won't pay them a dime however since I found the chip that burnt at
www.digikey.com for $0.69 each. I ordered four of them.
Here is what happened: The chip in question has 7 transistor gates on it, six of which are meant to fire the ignition coils. The problem is that they are only capable of sinking 500 miliamps of current. Our coils on our engine are less than 5 ohms resistance, so they allow close to 10 amps!
That was why the chip toasted immediately.
Steve and I have put our collective brains together and come up with a simple and cheap solution that will enable us to use the GReddy to fire the ignition coils without burning anything up. We will use 3 high-current mosfets that will be activated by the GReddy unit and in turn will fire the coils. This will allow the full use of the ignition timing map and still protect the GReddy unit from destruction.
I will schedule dyno time for next Thursday with Streetflight in Chandler AZ. This is the place making the Turbo kit. That is where I dyno'd my car last time, so I should be able to see just what kind of gains the GReddy can make for us.
