Guys,Just came across another tread that given such a recommendation to improve your drive. Here's "SHOGUN" reset. Have heard that it is now standard first step for all dealer service of m70s. Changed plugs on '89 m20 5s and disconnected batt cable to boost charge for more accurate compression check. Running much, much smoother now and seems stronger. Gave credit to the plugs but the reset may have helped. ----------------------------------------------------------------------------------------------Anyone heard of the "Shogun" computer reset techniques?Procedure: Following is a procedure for resetting the computers on a M70 engine. However, the posting stated it would work with any BMW including the e34. Supposed to clear out the adapative memory and allow relearning (or similar) for all the various vehicle computers?? Somehow this seems risky. Would it benefit our cars, especially the 525i 4 speed auto without an adaptive transmission? 1. disconnect battery cables, first -, then + 2. turn ignition on position II 3. connect both battery cables ("short") for at least 10 minutes for drain of remaining power out of the system 4. ignition off 5. connect battery cables again to battery, first +, then - Job done.

Yes, works great. Shogan forgot to mention that , if you want your car to be very responsive, you *must* drive very aggressively for 2 days after that, so the ECU will adapt to aggressive parameters it learns from your driving style.
If you take a slow cruise after the reset, you might complain the car is sluggish and it will take weeks to come to the right power. But then you will be amaze by its FC. My sedan improved on FC by almost 20% when it was in sluggish mode. Not great fun to drive but burns way less gas. Thats the compromise.
To me, it would not be a BMW if it cannot go fast when you need it!.

Will my ECU being reset if I disconnect the battery for the whole day and reconnect the batt on the next day ?
I don't understand this part -> . connect both battery cables ("short") for at least 10 minutes for drain of remaining power out of the system
means, + and - cable touching each other ??
