Where you go wrap this steering? or you DIY?:rolleyes:
These sort of wrap was popular last time. Had to search many shops before I found it. Wrapped myself. Quite easy.

I like thicker steering. The feel is good. Very good grip :top:

Hey, if you do manage to find this wrap, let me know where. Want to keep spare

standard size. Not sure the size. Currently using aftermarket 350mm. Just nice.
Mod not much on that subaru steering. Clock spring cable connection only.
I still modify the clock spring connector for hub and aftermarket steering.
Wah. You install clock spring ah?

mine is a 350mm Momo, perfect fit :driver:
Nice laa got MOMO

Sanekit - actually why haven't you discussed your wiring issues here. Perhaps some fellas here might see something your mech missed.

UPDATE on AC/Idling problem: as suggested by parakey and sanekit, i was at a DIY session with DDT as he guided me through the adjustment of TPS with multi meter. managed to get the reading right, screwed it down, did adjustments on the BISS screw (pretty much textbook style like links yous shared), started the car..

OK, good news is we finally made sure the stepper motor is working and TPS adjustment right - AC on, the RPM dropped and then was compensated, implying that signals are normal.

here comes the bad news, the RPM dropped to 600 then was re-compensated to only ~750 (NOT ENOUGH)

as we looked on, i'll first have to point out that my car is a VDO stock converted to MMC. ECU socket is MMC as opposed to VDO's 3 pin socket if not mistaken. based on Evo3 and '95 Mirage's ecu chart, my socket is MISSING 2 cables in 2 pins

PIN 37 - power steering pressure switch (yellow wire), non-existent from PS pump to socket
PIN 45 - AC compression relay (green&yellow wire), connected from AC fuse but not to socket aka patahilang

now, assuming these missing signals could be the factors why the ECU isn't processing, hence the slight void in RPM compensation during idling. opinions? i'll pry more at the mean time :stupido2:

750 rpm should be ok. if you check online mitsu manuals, 750-800rpm idling. AC on, 900rpm idling.

Adjust ISC/stepper motor ? If you still not satisfy. I have bad time as you.
Since i in Pg, DDT Franky at KL lahhh. Cant meet him. Buy tps and isc from him too. Good quality.
Try this way, which my last resort. Bit tough but will make sure isc is at correct position.
Warm up ur engine then off.
Unplug new isc connector, plug the cable to old isc as a decoy for ECU.
Unscrew the new isc (2 screw). Take out the whole piece from TB. Dont drop the O-ring.
ISC have 3 screw, unscrew it. Use flat screwdriver, slowly pull it out. Got one spring inside too.
Set aside spring piece.
Now the nipple piece. Use finger to rotate magnetic rotor clockwise/anti-clockwise, u will see it move in/out. Measure it or count it.

Set it to middle. Fix 2 piece together put back into TB.
While connector still with old isc, start the engine. Adjust BISS screw. Set 800rpm. Stable idling, off engine.
Plug connector back to new isc. Start engine then drive, AC ON.

Scantool method also same, it will lock the ISC position, then only adjust BISS screw. Less hassle loh. :rolleyes:
