Message	they will be releasing one for the Z in about 3-6 months. It uses the factory harness and sensors. It has control over whole host of things too many to list. You can control NOS, two-step rev limiter, boost, fuel/ignition maps, microwave lunch and play your DVDs. They are working on their own traction control system. The cpu in the AEM is from Hitachi and is 16/32bit hybrid. Sampling rate is 255 per second and resolution down to 1/2 degree of crank rotation. Why is sampling rate and resolution important? At 7500 rpm there are 125 revolutions in a second. Just FYI,in trouble-shooting my idle problems, it took about 4 minutes for the ecu to correct a/f ratio when I put a new 02 sensor in. It is sampling the a/f ratio every 2 seconds. There is some delay time between some sensor inputs and corrections. I'm sure it is much faster for reading TPS and MAF inputs. For 99% of the Z folks the stock ecu is fine with it's 3mhz 8-bit processor if you don't need all the bells and whistles. I may stay with it or go to the AEM depending on the costs/ benefit. Price is always a big factor.
