Turner Motorsport Conforti Performance Chips  |
| Pelican is pleased to now offer Turner Motorsport Conforti Performance chips for your E28 BMW. Developed by Bosch Motronic tuning expert Jim Conforti, with a few custom-tuned by TMS on our in-house Dynapack chassis dyno, they provide the ultimate in performance! Adding a performance chip to your car is the easiest, most cost effective way of increasing your BMWs performance with NO downsides. TMS performance chips are supplied with detailed instructions and are user installed in about an hour. The performance chip optimizes ignition timing and fuel curves which results in increased horsepower and torque. Must use 91 octane or higher gasoline. |

| Turner Motorsport Conforti Performance Chip, 528e (1985-87) |
| Horsepower Gain: +24 @ 4500RPM, Torque Gain: + 28 @ 5300RPM, New Rev Limit: 5300RPM The 2.7 liter inline-6 is a torquey car, however, performance drops off greatly after 4000 RPM. With a TMS Performance Chip power is boosted at all RPM but most importantly in the upper RPM. The car really feels more alive! This chip was tuned on the dyno to yield as much performance from this engine as possible and still maintain its strength and durability. Jim Conforti tuned the fuel and spark maps to take advantage of 91 octane gasoline. By making the engine more efficient with this fuel, gains in horsepower and torque are achieved as well as making the engine run smoother. NOTE: Your car may have a replacement DME ending in 021. This chip will work in this replacement computer as long as the existing chip is not soldered. |

| Turner Motorsport Conforti Performance Chip, 535i/is (1985-88) |
| Horsepower Gain: +24 @ 5000RPM, Torque Gain: + 29 @ 2000RPM, New Rev Limit: 6600RPM. The 3.5 inline-6 is a torquey car, however, it could be a little more powerful in the upper RPM range. With a TMS Performance Chip power is boosted at all RPM with over 20ft-lbs of torque gain at only 2000 RPM. This chip was tuned on the dyno to yield as much performance from this engine as possible and still maintain its strength and durability. Jim Conforti tuned the fuel and spark maps to take advantage of 91 octane gasoline. By making the engine more efficient with this fuel, gains in horsepower and torque are achieved as well as making the engine run smoother. Must use 91 octane or higher gasoline. NOTE: For the 1985-88 535i/is, you will have to check the part number on your ECU. If your ECU ends in 059, we will need to know the number of pins on your original chip. |

PEL-TMS059-240 | Turner Motorsport Conforti Performance Chip, ECU# 0-261-200-059 (Replaces 24 pin chip), 535i/is (1985-88) [More Info] | $388.00 | |
PEL-TMS059-280 | Turner Motorsport Conforti Performance Chip, ECU# 0-261-200-059 (Replaces 28 pin chip), 535i/is (1985-88) [More Info] | $388.00 | |
| Turner Motorsport Conforti Performance Chip, M5 (1988) |
| Horsepower Gain: +48 @ 6000RPM, Torque Gain: + 32 @ 5000RPM, New Rev Limit: 7200RPM. When the first M5 and M6 were brought to the U.S. they were de-tuned from their European brothers and sisters. That was a shame as the cars lost close to 40hp. But adding a TMS Performance Chip will get that lost horsepower back! Jim Conforti tuned these chips on the dyno to boost mid range torque and increase horsepower in the upper RPM range. As a result there is a 48 horsepower increase at 6000 RPM with a new rev limit of 7200 RPM! Conforti achieved this by tuning the car on the dyno, specifically changing the fuel and spark patterns in an effort to make the engine more efficient when burning 91+ octane fuel. Torque increases similarly in the heart of the powerband. There are NO downsides to installing a TMS Performance Chip; simply put, it is easy-to-install horsepower. |

Throttle Switches |
| Has your E28's idle gone crazy? Does it keep going back and forth with no apparent reason? The cause may be the throttle position switch. This switch is used to control the operation of the idle control valve, and cause a fluctuating idle if it is faulty. Over time, the small electrical connections inside can separate and render the unit useless. |
