Jul 15, 2012 update on gunner's 1988 BMW M5 (E28)

special prize inside!

So I opened up the ecu to do the solder thing when engine runs bad and I found out it has the Eurosport chip in it already. This is the chip I was already going to buy when I got the money together. specs:

Horsepower Gain + 48 @ 6000 RPM Torque Gain + 32 @ 5000 RPM New Rev Limit 7200 RPM nice! That should make 304 hp at the crank but Im gonna get it dynoed to verify. No wonder it feels so quick. its dated 1998 so it may or may not be identical to the current Comforti chip.
