I believe the problem is that the 99 does not have a socket that allows external modules to be plugged in.
One might wonder how difficult it would be to use a 98 ECU and remap it..surely the sensors/wiring is the same ?

There have been a lot of postings on this in the past. The current situation is that they are still working on it. Just have to be patient.
I have downloaded the 2 threads for my own personal records if you don't have any success in the archives.

There are alot of differences between the 98 ECU and the 99 ECU for starters it has a different number of sockets and runs twice as fast as the previous ECU. The remapping of the ECU is not a plug a module in but they reprogram the ECU itself.

In the same way that we convert all other ECU's, the aim is to make it undetectable to the dealer, even with the Subaru diagnostic equipment.
We have some progress but we are no nearer saying when we can offer the ECU conversion to MY99 cars.
Did anyone see the results from our ECU upgrade on the EVO Fast Fleet STiIV?
+30bhp +40lbs/ft AND 32MPG!!
This was on a car which had previously another modified ECU from another company, but they had to remove it before terminal detonation took hold.

We are trying to sort this from three different angles.
All parts have to be specially made. There is no kit which is designed to re-programme a processor which has been specifically designed so that it is not re-programmable.
I do not want to say too much because I have been accused of trying to create interest where none exists.
I only commented that there has been some progress. This means we have not failed or given up.

David,
Like everyone else with a MY99 I am waiting to see the results of an upgraded ECU.
There are obviously other things I can do to improve the response of the engine.
I intend to replace the air filter and exhaust system, but intend to keep the air box in place.
From your dyno results is this the right way to go wrt throttle response, are there much differences between a backbox and a "from the turbo back system" and I have read you have some details of the types of air filters to use and which is the best compromise.
Thanks.

Does anyone know if Prodrive replace the MY99 ECU or actually reprogram it. If someone could in someway mark their ECU prior to PP upgrade we could find out. If prodrive do reprogram, then we know it can be done. Otherwise, they would appear to be wasting an awful lot of good standard ECU's (which I doubt). I would imagine Standard/Prodrive/WRX/STI ECU's are all born the same (blank), and therefore be programmable (initially at least).
Maybe this gives some hope to the masses.
Good luck David, I hope all this development time/cost dosn't push the price up too much. I'm holding out for the PE upgrade, even though I drove a 99PP car last weekend and was sorely tempted.

This is to Dave Power,
Just a quick question...
What electronic design/analysis skills have you got in house ? Or do you contract this out? Who did you use to develop the Phase One upgrade ? Or was that using a standard "automotive" pin-out/piggy back format, so it was quite straight forward ?

not got my scoob yet, but it sounds like its under a month now!
I will hopefully be going this route myself, for two reasons, 1, this forum seems to believe there is not better method then the DP solution when you look at reliability and 2, as you say its non detectable by anyone.
I personally would accept something that is visible if it can be removed prior to taking to the garage (i.e. a piggy back ECU, or a carrier, something along those lines), but obviously the optimum solution is a re-programmed original.
Mr DP sir, will you develop something closer to a Superchips solution if your efforts to reprogramme turns up a blank?

Hi there,
There is nothing to develop for the superchip method. All they do is chop the voltage signal from the sensor (looks like its running lower boost) and they fit a bleed valve. You can make the kit for about 20quid (tops) or buy it for about 80 quid. If you were going to go that way (wouldnt recommend it)I would at least fit an electronic boost controller (even possibly an AFR device) to slightly richen the mixture (if needed).
Have you looked at the Link device (complete replacement ECU)? or any Jap products ? HKS ? Apexi ? They all offer Fuelling and Ignition computers that can work with or replace the standard ECU.
If DP cant find the solution from his sources (other companies), then I would consider the Link (is the wiring loom available for a V) ?
Cheers,
J.

sorry, my fault for not being clear.
When I said the superchip method, I meant, adding a bit of hardware to "change the signals". I didnt mean a crude mod as they do, but for Dave to do a more complex one.
Sorry for this confusion.

Orville,
I am also waiting for the PE upgrade and have been sorely tempted by the PP upgrade, but unlike you I have not driven a PP car and have based my temptation on Dyno results. What I would like to know is where did you feel the difference between standard and PP and how much of a difference was it in your opinion. I would be grateful for any comments.
Happy Motoring

Prodrive cannot re-programme. The work is done by STi in Japan. You are quite right there are a large number of spare ECU's around. We have bought loads of them from Subaru dealers during our testing.
The processor is a unique unit manufactured exclusively for Subaru by an electronics company which is owned by Nissan!!.
Reverse engineering is difficult and for obvious reasons I do not want to discuss how we are approaching trying to solve the problem.
Rest assured we are working hard, it is not impossible but this is not the first time we have carried out this type of work. We have been doing similar things for many years on many different types of ECU.

David,
Is it possible to buy shares in your company. I think you're gonna be rich when you crack it!
Not to mention making a lot of people happy!
Just a thought - Prodrive ECU's are modified by STi. Does that make them grey!!!
Obviously not 'cos IM make probably £1k clear profit per one unit. So that's alright.

bash,
The PP car I drove was a dealer demonstation model. As the dealer was in the car with me I couldn't really give it a good thrash but the difference was clearly noticed. My standard MY99 felt very slow in mid-range after the PP car. As a comparisson I would say the difference between the standard and PP cars is the same as the difference between a standard car with driver only versus the same car with 2 or 3 heavy passengers on board. The PE Phase 2 (when cracked) should give even more usable power.
regards
Andy.
