Rannoch,
Hello,
By the way it was nice to have met you and ut a face to the name.
Having discussed this further with pat, the link can run als but not as standard, something to do with the spec of ecu you purchase, whether for rally use or road use. It is interesting to learn that it can run launch control aswell.
When you say 95/97 switching is possible witha tuning module, does this mean it has the capacity to store multiple maps? if so how many?
Is there noway of creating a neater module for switching between them rather than having an interface lead protruding from your kickwell? I think this would be a great feature if attainable.

Rannoch: Not taking the 5th, just have a life I like to frequent. I was letting those with more experience of the Motec to explain. (and Adam M kindly obliged
)

Rannoch,
I don't really want to get involved in the "what on earth have you got to show for the extra £ you spent over a X ecu." arguments. You're happy with your link and I am glad for you, I am happy with my motec and you're concerned I've been ripped off!
I'm glad you care!
I am happy with my choice, and I should be as I took a long time making it, post PowerEngineering phiasco one.
I regard the als and launch control systems as toys I have as a side-effect of the ecu... rather like the shift light it also drives, these are nice, but not essential. The full data logging facility is, I consider, more of an essential tool.
The real point of spending the money on motec was the great increase in precision available to map the car. The link is essentially limited to 6 load sites, whereas the motec can be set up to give up to 40, IIRC.
Believe it or not, Powerstation managed to do a fantastic job of mapping the engine on their rolling road, with occasional ventures out onto the real roads to check how the car actually drives in normal conditions.
We will have to arrange to meet up sometime so we can passenger in each others cars... I'd be interested to see what another Linked car feels like, and I'd hope you would be at leas a little curious about mine.![](http://bbs.scoobynet.co.uk/smile.gif)
MikeR, dude,
Sorry, I thought you were just trying to cause trouble there mate!
Contact me offline if you really want more info on my dyno run...
Oh, and isn't the pectel system based on a 16bit microprocessor architecture? How very quaint!
Oh, and before you try the "pectel is multiprocessor" argument, so is the Motec.
hehe. BTW: Have you found a "correctly sized" turbo for your beast yet?
ARRON BIRD,
I noticed your post, even if no-one else did! Good point about the BS figures, but I suspect most of the other contributers to this thread are very keen drivers, hence the desire to further "improve" their car's performance to increase their enjoyment on the open road. After all, not everyone can affor to buy the prodrive tuned sti, so we have to make do with what we've got!

Whilst I'm very happy with the Link, the Motec is a great bit of kit. Wether it's worth the extra, or not, depends on what your looking for. I did start looking, but couldn't find the extra £1200/1500
.
As for a 95, and 97RON map, my concern would never quite knowing just what RON I had in the tank, and having to run a couple of full tankfulls first, to be certain would drive me crazy.
The Motec certainly does have some excellent extra features.
Mark.

Ran my P1 today at PS to see what the score was.
The car has 1500 miles on it, so is still very tight and hopefully should free up a bit over the 6-7000 miles. Temp was 18 degrees.
Fuel: the car has been run on Normal Unleaded with the occasional Super.
The first run gave 265bhp and 236lbft, but we noticed an interesting characteristic.
Unlike any other Scooby Ive seen on the Rollers my P1 held just over 1.00bar up untill approx 5750, then dropped to just below. Approx 16 down to 14psi. The drop was not a gentle slope unlike every other one Ive seen a plot for at PS, but a sudden step.
We tried two more runs after adjusting wheelbase, but each time the exact same thing happens. The Stethascope (bad spelling) was put on the third run to check for any detting, but there wasnt any.
By the third run power had dropped a little to 261.
Any thoughts anyone ?

Shaun - you're a bad boy! ![](http://bbs.scoobynet.co.uk/wink.gif)
Jonathan - on 22b.com there is a comment that the P1 ECU will cut boost on 95RON to protect against det. As the PS rollers have a high load impedence, that they don't wind off at higher revs, maybe this was the safety cutting in - or this could just be bollox![](http://bbs.scoobynet.co.uk/redface.gif)
Moray - I absolutely, really did not want to suggest that your MoTEC was not good value, or a great ECU - I was concerned that there was an earlier comment that MoTEC was great - and that everything else was was a misguided choice, which I suspected was unfounded BS. I just wanted to test how this sweeping statement would be supported.
By the way - the LINK will datalog too
(altho you need a storage buffer or you have to plug your PC in!).
Bottom line - if I wasn't the pioneer I would have gone MoTEC too - but no-one anywhere seems to have done a Phase II engine - yet - I am sure that it will come.![](http://bbs.scoobynet.co.uk/biggrin.gif)
Cheers,
R

Well I think you done quite well you only lost 23 BHP and 12 lbs/ft since PE.
Think of me I have lost 40 BHP and 28 lbs/ft
But I informed my insurance and have got it £50 cheaper this year.

So my estimate of 230lbs torque for the P1 is not that far out! - surprised that the bhp was so high though.
In standard trim my sti5 boost peaked at 14.5 psi - so P1 is about right.
Interesting that they cut the boost out, this pretty much proves its an sti5 ecu that they've retarded to avoid warranty problems - 'a cheap sort out' - does this mean that the P1 owners can sue the manufacturer for false claims on the bhp and torque power output. If I had those figues I guess I'd want to do a bench dyno - see what that produced - and if significantly down - especially on torque I'd be taking legal advice!
Bob - any development with the brakes yet?

As it was all around at the Powerstation meet that Scoobymania had gone bust. I did not ring them to make an appointment for fitting. Just learned they are still going. will try to phone then next week.
Do I need better brakes with only 247 BHP.
Tons more torque than a P1 is that what counts![](http://bbs.scoobynet.co.uk/smile.gif)

Whilst dodging the rubbish in this thread I've found one thing to comment on.
Jonathon said that even with a stethascope the car wasnt detting in the least.
So why would the ecu be cutting boost then?
A guesswork knock sensor LOL ?

The ecu would cut boost based on temperature increase, thats what its designed to do, above 50 deg c air inlet temp boost is reduced progressively. Or ... the ecu is mapped that way !!

Next time I travel up that way I will run it on 97RON as that's what's need for max power. Also a few more miles on the clock might help.
The point I was making is that its not a steady decrease in boost. It was 16psi at 5750 and then 14psi at 5751. This occured on all three runs.
It will be interesting to see if this happens on 97RON. Its also nice to see that on poor fuel on the Rollers that everyone states will produce detting if anywhere, it did not det. Not sure you could say the same for an STI V on poor fuel. So maybe it is remapped.
