ALS system not working with a switch

Post by dochka »

Hi,
I'm just done mating a MS3 standalone ecu to an OEM Mitsubishi Lancer Evo 8 using a home made patch harness with a Denso connector..
Everything works great: fans, launch control, tacho, fuel pump priming, even ALS, but it's only turned on and off from the Tuner Studio software, i mean I can't leave it "On" in TS and control it by a Switch to ground on "Datalog In" let's say;
Another problem is the Stock Mitsubishi Stepper Idle valve doen't work, it has 6 pins , the 2 in the middle are +12V the others are for the 2 servo coils, didn't work.
Still have the A/C to setup and the Vehicle Speed Sensor...
Been a great project so far

I see you are using the 1.4 beta code - do you have the same problem on 1.3.4 release firmware?

Yes Right, I see that all the time while the clutch pedal is disengaged !
When I depress the clutch pedal, It lights ON and stabilises and Launch control works

Take a look at the manual, page 45:
Other manufacturers use 5- or 6-wire steppers which are uni-polar.

These are usually wired as shown in the schematic below, with a center tap on each of two windings. In use, the
center taps of the windings are typically wired to the 12V supply, and the two ends of each winding are
alternately grounded to reverse the direction of the field provided by that winding.

Thanks Dontz,
Yep, I used that schematic, it's listed in the mitsubishi manuals too...
