you'll need to wire it at the tcu. the one that engages the solenoid. there should be tonnes of wiring diagram online.

Did you mean the universal gear position indicator or stock BMW instrument ?

Thanks,

My mechanic is using Dakota Universal Tachometer Signal Interface to read the RPM signal, i read from somewhere if my cluster is from a 4cyl BMW engine, the RPM signal may off by a little compared to a 6cyl. Should i try off with a 6cyl BMW E46 cluster ?

Thanks,
Ken

dont have to change cluster, the Dakota Universal Tachometer Signal Interface allows 4 to 6 cylinder calibration.

TCU is transmission control unit. not the lever position indicator.

Wow thanks, guess i will suggest the guy to try recalibrate again.

is it SGI-8E?

The SGI-8E is capable of recalibrating tachometer signals from 1 to 16 cylinder applications and anything in between!

can check the specs easily here: http://www.dakotadigital.com/index....t_id=127/category_id=694/mode=prod/prd127.htm

Yes it is, the mech is first time using Dakota, i will let him know of this, right now i think the signal still reads 4 cylinders.

yea, probably he didnt know how to set, well there should be user manual in the webpage. tell us the progress. haha

tap the wire at the TCU from the indicator. unless u buy those with can bus like this one from cartek: https://www.cartekmotorsport.com/digital-gear-indicator/

my old 4g9x/6x mitsubishi/protons, we have this shift box from forced four that we can use to bypass the solenoid and do manual shifting. http://www.forcedfour.com/index.html. i've been researching on this but dont have the time and budget to it on my car yet.

Will do, visiting him tomorrow for spot checking. Need to rush him to complete the tidy up.

How much it cost for the digital gear indicator ? I am interested !

not cheap. GBP110. http://www.cartek-store.com/Catalogue/Cartek-Motorsport-Electronics/GEAR-INDICATORS

Yup i do know about the price, but any local distributor ? Or other equivalent device ? Just want see my gear position so i am not prepare to spend over RM300 for such device.

i dont know any local shops bring this kind of stuff for cars. there's the ones for bikes which i dont know how to wire it.

you can search on mudah.my at motorcycle accessories and parts for gear indicator. there's a lot for bikes. but non for cars.

Alright we managed to recalibrate the signal interface, now its reading is 660 - 670 steadily, according to my sources the reading should be somewhere near 680-700. For a converted vehicle, i would say its near perfect, so i will give it a rest for now and work on finalizing the housekeeping in the car. Its damn filthy after 3 months stuck in the garage.

The mechanic suggested if the voltage of the indicator is same with car's one, then he can try to make it work. However it's a bit risky cause i hav to buy it and try, there's no loaning and try. I will try to buy a used indicator for experiment, if i am lucky, it should work.

should be same 12v. good luck!

I got to test drove it (finally) properly on highways, the conversion was a success ! No weird front end vibration nor disconnected feeling between the engine and the chassis.

Issues found:
1.) The headlights of the car seems to be dimmer and only get brighter when throttle is applied. Think there's power disruption or just weak battery which i haven't change for the last 4 years.

2.) There's knocking sound from the rear lower arm too, probably the bushings went out due to suspended in the mid air for excessive period of time.

3.) Gear lever is not perfect inline, will need to send this to another specialist that can make it perfectly inline with stock BMW gear lever

4.) Sport mode or shiftronic is not available, will need another specialist that can wire this probably with some additional costs.

Other than that the conversion is flawless, engine is very powerful, brakes are still sufficient (need better brake pads and disc rotors). Stock absorber and springs are sufficient, no excessive rolling or nose dive when driven hard. I do detect some rear squat when accelerating hard, however overall the driving experience is still pretty satisfying and pretty much feel much like stock.

Verdict:
Before conversion, please upgrade the suspension components like higher grade absorber, bushings, antiroll bars or whatever so the car can take much abuse. Brakes to be upgraded to 325 or 330 model so that you will have stronger bite and larger disc. The overall conversion cost me 20k while excluding brake and suspension upgrade, fortunately the CI's absorber is sufficient to handle. Otherwise i wouldn't dare to drive the car fast.

Apparently my idea don't work. Due to the motorcycle gear indicator can not read PNRD not 1 - 2 - 3 - 4 from automatic transmission. Guess i have to get the expensive solution.
