Does anyone have motronic55 pinout for M20B25 engine (from BMW 325 IX E30 1987..90) ?
- We received pinout from a guy who made Econoseal-motronic55 adapter harness earlier, but it would be good to verify
TODO: links (found a few of the 35 pin, but the 55pin would be needed)
- Autodata definitely has the 55 pin motronic (1.3) pinout for the e30 325i which prooved to be correct in my measurements (MembersPage/GergelyLezsak)
We will make an adapter so VEMS motronic55 with this pinout can be reasonably tested as well.
Idle air controller
Anyone knows
- what flyback (low or high voltage) ? The 1-solenoid audi likes low voltage (schottky) and high freq, while BMW likes lower freq and perhaps 6..30V flyback.
- and frequency (iac_speed setting) is optimal for this iac valve ?
- maybe PID settings for certain engine ?
Gergely Lezsak made a few engines, he wrote some docs too, thanx :
