A bit about this car and owner... Bout six years ago, I somehow ended up visiting Bogota, Colombia, on my way to Madrid, Spain; I liked it, I stayed. I mainly enjoyed the simplicity of Colombian life, the beauty of Colombian women, the low cost of living and the miriad of opportunities I found.
Some uneventfull day about year + 1/2 ago, I was offered a Turbo US spec 1988 ///M5 !!! Of course I did not believe it because BMW never made such a beast. Some three months later, I was told about the same beast; that it was almost 80%disassembled, rusting away somewhere, missing parts and that it was looking for a good home, where someone would understand the mechanics of such a modern beast.
Not convinced of the authenticity of the car, I made the arrangements to go see it for myself. Lo and behold...!!!??? it was a real 1988///M5 with a Turbo, 37.000 miles, in apparent perfect condition... It turns out itīs the only ///M5 in the country! Of course, I bought it knowing that it needed tons and tons of loving care, some hard to find parts in a country where the most common mode of transportation is the Renault 4 and other Korean and Japanese numbers, where the minimum wage is US130 dolars per month (60 hours/week), where you can dine and wine with a lady in the best of places, as elegant as in any European city for about US$40.00, but where you cannot get a proper tune up on a VW beetle for lack of proper info.
A year has now passed and the car has been assembled to the best of my knowledge. Itīs not a turbo anymore because BMW never meant it to be in the first place. I have managed to obtain some info on engine specs thru the Net, but not enough.
I have been enjoying this car immensely traveling through the most challenging roads in this countryīs geography with some of the most beautiful scenery I have ever seen (I once made the trip from Madrid to New Dehli in a VW Fastback), and the ///M5 has shone for all the things it is capable of doing, excellent performance, handling, although it lacks a bit in the brake department due to all the bias problems it came with, but all in all, I have enjoyed it more than anything else I have owned in my life (Porsches, Minis with Suzuki 1300 twin cam engines, AMG Mercedez, and even one older Ferrari).
My problem is:
When the aftermarket turbo was installed, the connections from the ECU (US spec) to the Oxygen Sensor were made to disappear as if they had never existed... Althoug the car runs fine, It is a nightmare to pass emission control tests (recently implemented), and it darkens the plugs when ran in city traffic resulting in slight missfires until they clean up. I believe that the O2 sensor is critical in this case because we are at 2.600 meters above sea level, and one of the most difficult things to do is to properly "carburate" an engine, even if it comes with a Motronic injection as it is the case.
Can anyone help with a schematic of the US spec ECU??? I have not had much luck through the net. The local BMW dealer has never had anything to do with ///Ms until recent years, and only with the ///M3. As a matter of fact, there are only 5 more ///Ms (E34s) in the country and they are stowed away, never used... something might brake??? because there are no spare parts available, no mechanics, no tools, just amazement at the fine machinery!!! Please someone, help me enjoy.
