Apart from the cruise control, does the car drive/function normally without the tune?
AshDVS;69029 wroteIs it currently unregistered?

That's a bit of a list but not too bad.
Yes it is, I took the plates off it last year as I knew it would be some time before the car was back on the road, and I needed the refund money to get started on the project.

And yeah its a bit of a list, some of these items have been a problem since Ive owned the car, just fixing it now.
clinton;69046 wroteApart from the cruise control, does the car drive/function normally without the tune?
Yeah it drives fine as it is now. Arguably probably a bit better than it will with the manual tune. The auto tune keeps the throttle on a bit between gear changes (for smoother auto shifts), and it continues to do it as a manual, so it makes changing gear very easy. Im led to believe the manual tune doesn't do that, the revs drop quicker.

The problem is the ECU thinks its in Neutral, so it will let the engine start, but not let the cruise work (as the cruise uses the inverse, it wants to be in drive to work). The manual cars have an additional clutch position sensor, wired into the ECU. Ive added the pins to my ECU and it will be wired in today but it won't work until the tune is put on to accept it. The sensor just disengages the cruise when you put the clutch in.
That is awesome!.
It seems like the cost of a tune might outweigh the benefit of having the cruise control, particularly on a manual car. But, to be fair, I have never really been a fan of cruise control on manual cars ;-)
Manuals and cruise are fine. I don't know why it would feel different to an auto, just you need to pay some more attention to the road speed so you can shift down instead?

Tuning costs are varied but for a simple tune and removal of the auto feedback, it won't be expensive. And considering I want to drive the thing around the bloody country, I think cruise will be well worth it. I also passionately hate the idea of having the cruise control switch on the car but not doing anything. It may as well be a blank switch, which I also passionately hate.

For those of you who want a time lapse video of the entire conversion, see above.
Philia_Bear;69195 wroteTime for brake upgrade and bigger turbo?
Brake upgrade will happen when these ones are due for replacement (won't be too far away) and turbo when I have money... So basically, yep. Not done with this car yet HAHA.
2 years later
Necroing an old thread, but wanted to say nice writeup and pics.
Any rough estimate of the final cost, I saw some numbers but not sure it was everything.
Wondering the cost difference should the TF80SC in mine ever die.

Thanks
Did similar recently, check out: https://ozvolvo.org/discussion/7665/p2-enhoerning

The costly bits are the box and driveshafts, but given enough time they can be tracked down for the right price. Use an 850 single mass flywheel to keep the cost down.

Has to be pre mid 04 to do properly.
I paid a lot of money, Ive never wanted to put the final price up as some people are very judgemental on this forum, hence why I basically never come on here anymore. But I was under time pressure so I had to buy a lot of new parts, if you have the time to wait, the correct parts can be found on the used market for way less $

But its been like 2.5 years now since conversion and the car is still going strong, no complaints at all. I am in the process of updating my YouTube channel with some more info about the conversion after many people have requested it. I may write up a guide too but eh, I feel like my crown has been somewhat removed in recent years with other members doing similar conversions so I almost don't see the point anymore.
I haven't seen or heard of any other conversions?

(And Im not having a go at anyone, everyone is welcome to do their own conversions I wasn't the first nor the last but I felt I copped alot more criticism over mine than anyone else has so I just cbf with it anymore)

Understand, if you want to PM me I promise I wont be judgmental.
I just did the math on what my exhaust cost me all up including shipping and govt thefttaxes, and it came to $2850, before fitting. Surely it's cheaper than that :smiley:
Haha I assure you it wasn't cheaper the $2850, PM Sent.
I loved reading the build, such a gutsy move too as a first go at such a job, a massive learning curve too.
Amazing effort Jay.
