E46 318i 2002 auto to manual conversion

[tropos_net]

bro, using INPA you could probably hv access to the check box in ecu transmission mode to mark the manual mode. so ecu would know its a manual. the same ecu is used for both transmission. so at least that way the engine ecu can optimize the fuel and timing maps as it runs. but how are you going to recode the rest of the modules? then the removal of the EGS?

Bro, short answer here as I need to leave and drive. The plan is to use GT1 to reprogram all the modules. Yes the same DME is used for both manual/auto just need to reprogram. Before reprogramming, EGS need to be disconnected first.

Marvellous work there bro aidilj. Satgi balik penang boleh pekena teh tarik. Suruh McFir belanja

I'm also missing a hardware before programming which is the clutch switch. This will be connected to the DME to cancel off cruise control and to start the car.

Do let me and McFir7 know when you are around. Thanks for the kind words.

Update after driving back to hometown, the car is torquey but lost top speed. Please see page one for rev difference. Cruise control works fine without programming but depressing the clutch will cause engine to rev till redline, need to cancel cruise with the brake first. This behavior should be fixed after wiring the clutch switch and the car is reporgrammed.

Some work done is wiring the reverse light and covering a hole.

Hole used to channel auto shifter cable to gearbox

JB welded with sumo cap

Soundproofing

Reverse (light/function) relay location

Closeup

After wiring the reverse switch, the reverse light and PDC works. The relay is supposed to be activated by the EGS, in this case, the relay removed and bypassed, EGS output ignored.

CDV delete

Skipped lunch and went to machanic to have this done - removal of CDV (clutch delay valve). This is a valve installed by BMW into most if not all manual trans vehicle. It is a quick and free (no buying new component) mod. Now the clutch response as intended, not dumbed down.

Read more on CDV here : www.zeckhausen.com/cdv.htm

It's a simple unplug, remove, replug and bleed process. Highly recommend manual trans user to do this if havent.

Bro, I have a question and may need your advice with regards to PDC.

After manual conversion, my PDC became flip-flop, ie 1st engage R - PDC on, free, 2nd engage R - PDC off.
When in R, whether PDC is on or off, pressing PDC would not change its state.
During conversion, foreman said they initially couldn't get PDC to work but in the end, he wired the PDC switch to reverse lamp wiring (or something like that).

Do you think it's still possible to troubleshoot this PDC problem?

Bro, I need to do some reading and study E39 schematic to understand the difference between auto and manual. It sounds like there is a PDC button?

 

[aidilj]

Seewai Bro, saw your other post that the reverse has become a toggle switch for PDC. Now I understand. And E39 has a switch to turn on PDC manually.

If like mine, getting the reverse light to turn on thru its original relay will also turn PDC on properly. How is the reverse light wired?

Bro aidilj, I've no idea how it's wired but was told by the foreman he actually tapped the reverse light wire to make the PDC somewhat function.

Yes there's a PDC button to switch it on manually. I'll need to check in detail with the foreman to further understand what actually took place 2 years back.

So there's no PDC button in your E46?

Bro seewai, I haven't looked at WDS yet for the wiring. During the conversion, was wiring harness also transplanted?

No my e46 doesn't have it

Not long after the conversion is done, a noise emerged whenever the car is revved and when it's started from cold. It was disgnosed to be exhaust leak/crack at the manifold, fingers crossed it is just that. The mechanic said too much rempiting, but the car made it to Kuala Terengganu and back no problem (leak is there already during Pangkor drive). The noise is very apparent outside but from the cabin is just some ticking noise when accelerating..

Sifu, i think i hv a similar issue on my ride as well..(without manual conversion of course)hehehehe..in my case when im accelerating, i can always hear more like a hissing or a screaming sound from the cabin..more to the co-driver side...but outside near to engine bay, its absolute normal..still trying my best to figure it out since dat sound irritates my wife most of the time..hmmmm..

bravooooo bro....

Bro, the exhaust manifold is on the driver side while on the passenger side is the intake manifold. Yours could be related to the intake portion instead..

bravooooo bro....

Thanks Bro

Your source is most probably correct Bro, but blame it on the car since it inspires confidence too. In spite the exhaust leak..

Always a pleasure meeting a DIYer furthermore a super duper senior

roger that Sifu..thanks for the info..will get it checked..

Bro eujinee, thanks for the kind words. I guess this is desperate times which require desperate measures. I'm sure given the circumstances, anyone would be able to undertake this. Cheers.
