A4/B6 1.8T Motec Advice

[gccooper]

Hi,

I have transplanted a 1.8T from an 01 A4 into a mid engined sports car I am building. The standard computer refuses to allow the car to start due to the missing systems (e.g air bags, abs), so am looking at installing a Motec system to run the car.

Has anyone installed a Motec system into an Audi in Sydney?

Can anyone recommend a Motec supplier in Sydney?

Regards
Glenn

Those modules won't prevent it from running. The immobilisation will though. Custom-Code can defeat the immobiliser at the same time, as carrying out a flash. There is an extra cost involved but nothing in the grand scheme of things.

This would be less effort than MOTEC and the following tuning that would be required.

Another option would be doing the same as Golf Loon has done with his Scirocco. That uses DTA IIRC but comes with software to up the power as part of the package.

B6 is a nightmare Gav, i looked at putting a manual in mine if the CVT goes south, way too costly for it, Engine ECU and dash cluster, if the Airbag and ABS are missing on that car he might well have dramas, you loose the Can signal, Ive just looked at Treg with Crash data , crash signal cut the start signal for the engine ECU, and if you remove the airbag ecu it still wouldnt start, it had to be physically erased to allow it to start, not sure about the B6 really but i know from conversations with the guys in the Uk they are tricky correct me if im wrong, you will at least need the cluster that is matched to an existing ecu including keys and reading spool. You could go with what Loon has or call Troy at EFI Performance 38018075 they supply many set ups, mainly for the high horse stuff but he would point you the right way if not. He is well switched on, ive attended tuning seminar that he held and ive booked well ahead for the follow ups. Give him a ring.

You shouldnt have too many issues running standard wiring harness with matched fusebox running engine components . You'll still need a good electrician to sort out speedo signal etc . As Gavin said immobiliser and emmissions can be deleted if need be . Just make sure you run wideband , narrowband is terrible to tune

Audi didn't sort the immobiliser out when he took it round to them. He has all the gear from the donor car.

James has done some transplants into Lotus Elises, he has done some good tunes for them. He didn't think there would be any problems. Might be different to fit a manual box into yours if the engine ECU is expecting to see chatter from another ECU.

Will get the ECU read before sending it away, to see what it's complaining about.

Why not just run a manual ecu ??

Interesting, how is the immob deleted????ive heard of it but havent dont it or had to do it frankly , too busy fixing broken ones personally, im keen to know as i might have a future project and that would be nice to know. I make comment about the can signals and matched clusters etc as my main experience is with orig vehicles and not slotting these things into different vehicles, so like some others would be keen to know how, any further info or links???
Cheers and thankfully something interesting to read about

The engine ecu ignores the immobiliser signal . Thats all I know . PM Seb he can help you with any ECU issues you have

Interesting..... Motec is top of the line but dont discard ur Ecus like Autronic or EMS....they ar very good as well ! U would have more money back in the pocket...with less over kill.

[Pete@ECSTuning]

I'd have to agree with most of what has been said here. Don't go to motec just yet. I think you should snag a manual ecu and a vag com setup from ross-tech. From there you can program in an out most everything you need to. And since vag com has been around for so long, the online support is quite good. You can google things like immobilizer vagcom and get all the steps you'd need.

I have to agree. With a setup like this there is no need to try and keep the standard system in place. An aftermarket setup like an Autronic SM4,EMS or Motec is ideal for this. I use an SM4 myself and we've installed many setups similar to this over the years. What you find is the initial expense is quickly recovered when it comes to tuning as its all done in real time plus its easy to cater for non standard parts and so on. Both of the above are more than capable as is Motec of course
If it were a standard A4 its a totally different story as there are to many systems to look after.

Just out of curiosity, what is the going rate for that aftermarket set up, figures would be good. We seem to be mentioning cost but avoiding it at the same time, im keen to know.

Well the Autronic SM4s depending on the model they go up to round 2.4K. Then you'd be up for installation unless you did that yourself. On top of that there is tuning/dyno time. That $$ figure is for a PnP SM4 that drops straight into the factory wiring loom in a lowly EVO or Subaru so the standalone SM4 is less and this is what you'd use in this setup. You could probably get away with a lower spec model but most go for the greater number of inputs and outputs of the top line models.
Like with the Motec and Haltecs you can get a pretty cool race dash logger and other stuff. Boost control is onboard etc etc. All of them now interface to the mainline dynos for super quick minimum best timing for max torque tuning and so on
I'll find out a proper figure tomorrow for my own benefit its all changed recently

OK just checked, the stand alone SM4's are roughly $2200.
You can do all funky traction control stuff too if you have enough spare inputs. A bit more advanced than the factory TC in this regard as you can set it up to suit the vehicle mass power and track type etc

Same goes for Motec of course but there are even more option and In fact you can even have traction control using a GPS position for a reference. They do this in the Dakar and similar

[h100vw]

Is that $2200 plus dyno time or drive in and out?
