ACS523i 0 Report post Posted October 14, 2010 Hi A friend of mine with a 98 523i has been given a 'performance module' that he wants to put in. A mate of his bought it off Trademe a couple of years back, it's like a wire with a rubber bit in the middle and you fit it on the Airflow sensor, supposedley giving more power & torque 'not at the expense of fuel economy'. I'm a little dubeous, has anyone heard of or fitted these performance modules?? Do they work, or cause problems?? Cheers Steve Quote Share this post Link to post Share on other sites

ACS523i 0 Report post Posted October 19, 2010 Thanks Guys I have advised him accordingly to file his 'resistor' under R ....... I guess if it looks cheap nasty and flimsy - then it is huh?? Now he's talking turbocharging his 5 - talk about flip flopping OFFS!!! Have told him if he wants a Hairdryer powered wagon, then do it true and proper and Source an old BMW Alpina B10 Bi-Turbo !!!!!!!!!! Quote Share this post Link to post Share on other sites

Tristan 338 Report post Posted October 20, 2010 lolwut? There are some interesting mods on esstuning.com for E39s incl. steptronic improvement software and an ECU thingy which I cant remember but both looked interesting. The ECU boasted an improvement of 5hp? About 500NZD each as I recall. Quote Share this post Link to post Share on other sites

It is a proper performance module to measure the performance of your E39. Here is how it works: 1. Carefully unpack it and make sure it is clean and free of grease. This is important, as grease can severly affect the performance of these modules 2. For the installation and initial usage of the device, choose a suitable area where you can test the car to its full performance, such as a deserted racetrack, industrial area late at night, or a shopping mall car park 3. Position the vehicle so that at least 200m of clear road surface exists ahead of you, and 100m clear area behind you 4. Ensure the engine has reached normal operating temperature and that tyres are correctly inflated 5. Ensure all flag marshals and viewers are clear of the road. Ensure cameras are running to record the performance test. 6. The important bit: now carefully place the device in front of your left, rear wheel. Just so it touches the wheel. 7. Get in the car, buckle up seat belt, start engine, and perform your best racing start you can 8. Return to your starting point. Locate the device and measure its distance from your starting point and it's size You can then calculate your vehicle performance using the formula: distance_from_starting_point_in_m * percentage_reduction_in_size = performance_factor Tip: To assist in assessing how other factors such as fuel type, tyre selection and launch style can affect vehicle performance, you can repeat the tests with more performance modules. These tests are best performed on factory-new, unopened performance modules I can supply them in boxes of 10 for only $29.95 per box (including bimmersport discount). Special offer: Order 3 boxes, and you get a free baseball cap. Order now on 0900-Imadumass Edited October 20, 2010 by jochen Quote Share this post Link to post Share on other sites
jochen 4 Report post Posted October 20, 2010 (edited) best performance module for a 5er is a m62TUB44 Now hybrid, you are still new to E39s so I may forgive you for your grave and serious error The best performance module is NOT the M62TUB44, but rather the S62B50 By a long shot....
