Title: BMW E30 325i Matt black, VEMS and Turbo currently at 1.2bar boost
Post by: gunni on April 11, 2009, 05:38:27 pm

I just installed and mapped this 325i.

I reused as much as possible from the wiring loom to keep the engine bay clean. Worked out great.


Standard rebuild m20b25

9.7 compression engine
0.140 MLS headgasket
ARP headbolts

UUC Stage II clutch
Poly urethane everywhere

T4 Turbo

Oversized radiator is keeping the engine temps steady  wich is great cause it´s going to be used
for drifting mainly.

Owner ran against a "sorted" STi yesterday. Dead even ..

Now at 1.5bar
it´s also now got the variable boost control function working nicely.
a 0-5k ohm resistor with a 5v feed makes adjusting boost real nice and easy from
inside the cockpit.

That sounds nice and that is a function that I would like to have!  ;)
What firmware are you using?

1.1.44alpha2

No issues with anything.

the 450cc injectors are at about 82-84% at peak duty now.
