This is a new EPROM chip programmed to disable the VATS system on any equipped 86-92 TPI car. Please specify which year, engine, and transmission the car was equipped with after purchase, as each chip varies depending on the car and ECM. 

Other options are available for a very nominal fee. EGR deletes, timing bumps, TCC lock up changes, cold start deletes, injector changes, etc. please contact me for more information. 

Please note: this chip requires the use of a memcal adapter which runs at about $35. I can supply said adapter at cost. The other option is to solder this chip into the factory memcal. Please let me know after the auction ends.
