M3 E36 German Spec mods

[cvn]

Howzit, im new to the forum, looking to mod my brothers german spec. Looking at decat, chip and an airbox mod. any advice and who to use for these mods???

No need to do decat, 3.0 didnt come with cats.

I suggest adding a full TNT exhaust to your list, otherwise sounds good.

Didn't the German Spec come with cats? From what I remember, the SA built 3.0l did not have the cats.

Nope both didnt have cats from what i know, mine didnt.

 

[Theo D]

Neither did mine...

my bro is a 95 model, will check for cats, any suggestions on the air box mods and who to take it to for the chip as i have heard software cannot be loaded due to no obd port...

Howzit boet if you have a look of the threads the guys posted on the 3l m3 mods you'll pick up some good tips.

look under the car to settle the argument if they put cats on yr German spec, I dont think so as it was not a requirement in SA at the time so it would be an extra expense BMW could save on.
the good guys our there will know how to load even if its a chip replacement.

DME (ECU) should be a Bosch Motronic assuming you have the 3L not the 3.2L

M3 - Euro E36 S50/B30 93-95 0 261 203 075 Bosch Motronic M3.3
(The US models had the M3.3.1)

The Motronic 1.7 and subfamilies, and the M3 and it's variants are the next generation of BMW ECUs. The M1.7 was used on the M40, M42 and M70, the M1.7.1 was used solely for the S70, used in the BMW 850CSi. M1.7.2 was used for the M42 and M43 4 Cylinders.
The M3.1 is a 6cyl ECU, used on the early M50 24v engines without VANOS. The M3.3 family were used to run the later 3.8 litre S38b38, the S50 3.0 M3, and the M60 V8s. M3.3.1 included VANOS control, and is used on M50 engines with VANOS, introduced to the E34 and E36 in 1992.


I like the Motronic's as they're quite easy to mod
There is a semi popular mod for these ones where you remove the maf, and run in alpha-n mode.


Chip should be a socketed EEPROM, so easy peasy to replace.

Very good writeup on where the maps are within the eeprom here - http://www.bimmerforums.co.uk/forum/f37/bosch-0-261-203-075-lets-do-it-t13866/

I guess TunerPro or WinOLS and 1/2 hour of work should do it..

Is there much call for this kind of thing here?

I pretty much have all the software tools with me, although I don't have an EEPROM programmer, but thats not hard to find..
