Clean the air intake manifold thoroughly to remove drill chaff. Important Information — Please read. See Figure 5. At a convenient point, splice circuit into the cruise control switched ground circuit. If necessary, use a volt-ohm meter to verify the circuit before splicing in circuit See Figure 4. To speed up the testing of cruise control switches, quick check tables have been developed. These tests are to be run with the ignition ON, and the engine not running.

We have done our testing and none of the programming services we offer will trigger higher than stock emissions in a grams per horsepower-hour standard. Provided your engine is healthy, your injectors, cam, and pistons are factory for your engine model and serial number then you will get similar results.

The dynamometer graphs you see are horsepower and torque at the rear wheels. Wheel raw torque numbers are very high because the rear end ratio and tire size acts as a torque multiplier.

Series 71 was very popular in the United States. These engines powered almost everything. In the s and s, almost every intercity bus was equipped with such Detroit Diesel engines with 6 or 8 cylinders.

The characteristic sound of six-cylinder in-line vehicles was also often mentioned by soldiers involved in World War II.

Indisputable advantages, with simplicity at the forefront, made Detroit in various configurations a mass for infantry and tanks. What did the civil engineers appreciate, what did the builders of military vehicles appreciate. There were many cars on American construction sites equipped with 71 series two-stroke diesel engines.

Almost everyone emphasized the same features.
