Here's the deal first off Im new to this board and would like to extend welcomes to everyone. Approx. 3 weeks ago I got my new addition to our family, a 1999 Z28 w/ 38,000 miles mint cond. Now the dealer told me that the previous owner had a chip installed in the car. The car is fast, but this is the first Z I have ever drove and don't have it anything to compare too so basically Im just curious if the salesman was blowing smoke up my a** What I am wanting to know if there is any way to tell if the ecu has really been chipped. Some friends told me that if I drop my a4 in first and if doesnt shift on its own ( ya know bouncing off the rev limiter) that means the car has been chipped. Now I havent tried this cuz it sounds a little like bs. There is a dyno around here somewhere (columbus, OH) but I really dont know what a stock Z would put to the wheels. Any help on this would be greatly appreciated. Thanks in advance---> James

 

Sounds like B.S. I don't know why someone would reprogram the ECU if they didn't have any other mods (at least that's what it sounds like). Stock A4 should put down around 280-290rwhp.

The staying in first thing without it shifting works in my car and I know for sure the computer hasn't been programmed.

 

Dealer was telling you complete bull****. You should go back and call him out on it.

 

The computer in your car is flash memory, no chips. When you reprogram it, it flashes the new program into the computers memory. Sorry but no chips.

 

thats what I figured they will do whatever they can to try and make a sale. Thanks for the info guys

 

I'd rather they tell me the cars stock if it isn't
