Austec bespoke mapping

[the pits]

Has anyone here had this done? I like the sound of it.

A friend of mine claims to be really happy with something similar on his (brand new) Audi RS4. The basic idea is that the standard ecu map on all new cars is a big compromise that has to take into account boring stuff like emissions legislation and crappy grade fuel etc. A bespoke map as set up on a rolling road can optimise the car and can produce significant results. My friend is claiming 30 bhp extra. That sounds a bit optimistic but interesting none the less.

This type of tuning is commonplace on bikes that should be set up properly on a rolling road, when you stick on a race exhaust system. I did it on my Kawasaki ZX12r and the results were dramatic. Another 20bhp at the back wheel! It's a massive improvement in smoothness and throttle response too.

Your thoughts please gentlemen.

Suggest you talk to Nelly1.

Have a goosey here...

Even if you take the power figures with a pinch of salt (as most seem to ), the results are impressive to say the least.....

Do a quick 'remapping' search on the Cerbera forum for more happy customers

Believe me though when I say (without bias) that you WILL NOT find a more knowledgable team than Mssrs. Austin & Adams......

Pits...if Mark is involved the results will be good. He's ex my work mob, OK, different site, but same mob. Sometimes we even produce guys who know what they are doing!

There is also Track Car solutions. His work is that good that much of it has been copied by others.

thanks, I didn't know it but I'd replied to Nelly's thread before but have no recollection! Must have been a late Friday night post...

I will of course post the results of Thursday's exploratory session. But I am aware that their rolling road seems to be the most optimistic. This is just like bike tuners all over again...

'...ooh there's something wrong with this map, who did this for you? the fuelling's all over the place, we'll get you another 20bhp no problem etc.' [oily overall clad man flicks switch and graph leaps 20bhp (on screen)]. That said, both times my Kawasaki have been rolling road set up the results have been superb, it's just they can't help but have a go at their rivals.

I wouldn't get caught up in absolute figures, worry about how your car drives and if you feel it is an improvement. I would also take anything you read here with a pinch of salt and make your own mind up. Austec were the first to offer live mapping of the MBE ECU, so you're in good hands with plenty of experience.

I agree at Santa Pod recently all categories except one (the cerb) were won by cars done by Austec so as all rolling roads are different this is a good gauge of actual results. It also has to be said that Austecs best Cerb, Nicks, broke a driveshaft so didnt post a time, although I wouldnt have expected it to beat Cyclone, not with Nick driving anyway

As said before, dont believe all you read on here, make decisions on facts rather than fiction! Whoever you choose out of the guys mentioned above you will be happy with Im sure, I chose Austec and am very happy with the results.

IMHO

tragically, I couldn't get into the garage where the car is kept today so have had to put my rolling road trip off for another day. It's not a very interesting story but the car is kept in a friend's garage whilst in London and I couldn't get hold of him this morning to let me in. Oh dear.

Are there any issues re-mapping a speed6 in respect of changing temperatures underbonnet during the remap??

Not if you take the bonnet off.......

Not sure, but there is a setting in the ECU for atmospheric pressure so it calculates petrol magic using this as one variable. Surely the engine bay is just simply 'hot' all the time? Once the car is up to temp does it change much?

Exactly the reason for my question Targ - which should have stated engine bay rather than underbonet temperatures.

I spoke with someone quite a while ago about a remap for my T350 and was advised that it would be expensive as the only way to get a worthwhile remap was on an engine brake - making a remap quite costly.

I respected the chaps wealth of knowledge and understanding of both the car and the engine sufficiently not to "waste my money" on a rolling road re-map.

So you went out and bought a faster car instead

Incidentally, ever thought about remapping the Cerbera?

I would be amazed if there aren't significant benefits to be had. As mentioned the improvement in my bike is considerable (I know the underbonnet temp question doesn't really apply here) and I don't think TVRs standard software is up to much.

My take on it is simply that since the engines are hand built, there's more variation between TVR engines as a group and hence more likelyhood that the standard map is out compared to what it should be. Paul will return your car to how it was before if you don't like the results of the mapping, so what have you got to lose?

Had it well and truely remapped. Its been replaced by a Lotus Elise.

My basic understanding leads me to suggest the following:

Your bike has a far more sophisticated engine management control system and runs sequential fuel injection. The standard map is configured for Euro emmisions compliance, which does err on side of extreme caution and strangles the full potential of the motor. There is also a knock sensor loop which will retard the ignition if poor grade fuel is used. The TVR MB systems is a rather crude ECU with none of this. It runs batch fuel injection, it is not Euro 4 emmissions compliant (hence the factoy link up with Ricardo). The standard map is less of a compromise as compared to that which your bike will run, hence less room for gains and improvement. Replacing the MB ECU and going over to sequential injection will see further gains as then you can set the fueling per cylinder. No doubt there are other factors, but that will be part of the tried and tested secrets of the competent tuners to know how to exploit.

The sceptic in me would suggest that if significant gains have been made on a car I would guess that it has come about by the fact that there were other issues at fault as well, such as the map was way off to start with or fouled plugs or HT leads breaking down or goosed lambda sensor/s. The list in this area is exhaustive.

I could be entirely wrong but for healthy cars.... the term snake oil comes to mind. But what the hell the most important thing is .....that the owner is happy with the perceived after results.

Crikey, plastic surgery too...

iv spoke to austekc about doing this, they said there will deffinatly be more power available as it was found to be running lean on the rollers, going to get austec to service and re-map the car end of november so will post results
