5. Route the Accessory Cable. The loom with switches labeled and Map A/B can be routed where ever desired, but should be placed where it can be accessed. You can simply loop the loom inside the glove compartment, run it under the carpet pad, or permanently mount the switches as desired. See Section 16 for a description of the switches. 6. Replace the glove box. 7. Attach the glove box strut. 8. Reconnect and tighten the batterys negative terminal. 9. Accessory Cable Functionality
Switch Map A/B Mode I 0 Function More aggressive ignition timing Less aggressive ignition timing Notes Unless otherwise specified, for higher octane fuel Unless otherwise specifiedDefault operational setting
i. The normal position for the Map A/B switch is off ( 0 ), and unless you desire to run Map B, it should remain there. To change the switch position, turn off the ignition key before actuating the switch. ii. With the ignition key off and removed, Map A/B switchs on ( I ) position selects timing Map B. Using Map B may result in a CEL on some vehicles; the CEL results from that particular vehicles increased sensitivity to detonation.
Note: (1) More is not always better adding more timing can actually reduce power if your particular vehicle is sensitive to detonation. If the stock ECU detects detonation, it reduces timing to protect the engine. If youre truck doesnt seem to make more power than stock and youre running Map B, switch back to Map A and you will feel the power increase. This condition can and does occur even without a CEL.

Unichip Warranty Information
For 90 days following the original owners purchase of a Unichip, Unichip of North America (UNA) warrants no other ECU product generates more power from a specific gasoline engine than a properly functioning, custom tuned Unichip in the specific vehicle for which it is tuned. If another ECU product generates more power from that engine within 90 days of the original owners purchase of the Unichip, the original owner can contact their Unichip dealer for a refund of all Unichip parts, Unichip installation charges, and Unichip custom tuning. Shipping, testing, dynamometer costs and the cost of removing any UNA parts are specifically not covered by this warranty and will not be refunded to the owner. To claim a refund, owners must provide dynamometer proof another ECU product produced more power when installed on the specific vehicle and that vehicle and all of its parts were in an identical condition other than the ECU enhancement. Three repeatable dynamometer tests must be performed using the Unichip and three repeatable tests using the other ECU product. The average of the three tests performed on each product shall constitute that products score for determining power. The same technician, using the same dynamometer in an identical condition with the same settings, must perform all test runs. All environmental conditions including ambient and IAT temperature and pressure altitude and the vehicles cooling system temperatures and drive train temperatures must also be identical for all six runs. IAT and Coolant temperature data logged information for each run is required. The vehicle must also use the same fuel for all six tests. UNA reserves the rights to, at UNAs exclusive discretion, re-tune the Unichip involved in a performance warranty claim at no cost to the customer making the claim or to provide a warranty refund; if after a retune, the Unichip still makes less power than another product, the owner will receive a refund IAW this warranty statement. All UNA parts, including Unichip piggyback computers, driver modules, and harnesses also carry a limited warranty against manufacturers defect. This warranty is valid for the original owner only, for one year from the date of purchase regardless of the installation date. UNA only warrants Unichip products sold by an authorized UNA reseller. If a UNA product is found defective, the original purchaser may contact the reseller from whom they purchased the product for a replacement component at no cost. Shipping, testing, dynamometer costs, and the cost of removing any UNA parts are specifically not covered by this warranty and will not be refunded to the owner. The above warranties are expressly made in lieu of any and all other warranties, express or implied, including any warranty on the engineering or design of the goods as well as the implied warranties of merchantability and fitness for a particular purpose. Any and all warranties on the Unichip are void if: 1) the custom installation or custom tuning of the Unichip was performed by anyone other than a UNA qualified dealer or tuner, 2) anyone other than a qualified UNA tuner or dealer alters or modifies or attempts to alter or modify any of the electronic data within the Unichip or 3) the UNA product is used for anything other than its intended purpose or is physically or electrically damaged.
