Hi,

As far as I know...which is very little ;-) a MY03 UK WRX with PPP uses a EcuTek ECU.

On a Ecutek ECU I believe there is the facility to have two ECU maps and switch between them by holding full throttle and toggling the rear heated window switch from off to on.

On a PPP upgraded WRX, are there two maps that are switchable? or does this not apply?

Thanks,

Chris.

 

What modes does this offer?

 

I also hear if you hold it at half throttle and toggle the bright switch you can run on diesel.

 

Sorry to be ignorant what does ppp stand for

 

Prodrive Performance Pack

 

Its not 2 different maps!... if enabled, it switches between high boost mode and low boost mode.

not 100% sure but i wold'nt of thought the ppp allows this??

 

Prodive Performance Package? I think.

Although i belive in this thread 'Paul's Peruvian Pineapple' might be more appropriate in this thread, still i could be completely wrong

 

Not saying it does switch between two maps, just asking if anyone knowledgable in this area knows whether it does...

If the ECU is capable of two maps (or two boost levels) do Prodrive make use of both of them eg. one is standard and one is PPP mapped, or does the Ecutek in a PPP package only work on one boost level and/or one single map.

As said above, the ppp only has one setting!

 

I very much doubt that prodrive would use Ecutek mapping, and if they did i could be sure there would be no switchable maps in there, i'm sure the ecu doesn't have the capibility.

 

Prodrive do use Ecutek mapping/technology!!!! Its just that Prodrive produce the map as opposed to Bob rawle, Pat etc etc!

 

RB5Scott, it is two different maps.

Pockman, the new age ECU's have space for two separate maps that are, on standard cars, used to hold completely separate settings for manual and automatic transmission. The correct one is selected on assembly, so this feature rationalises Subaru's parts (and spares) supplies. Instead of needing to hold stocks of two different ECU's, they only need one.

While this feature can be subverted to carry user switchable high/low power maps (or high/low fuel economy etc.), it isn't something that is implemented on the PPP.

I'm not saying Prodrive uses anyone elses mapping, your missing my point mate.

1. Prodrive supply a EcuTek ECU unit loaded with a Prodrive developed map (I may be wrong with that point, anyone know the facts?).

2. An EcuTek ECU has the facility of having two boost levels which can be set when the unit is mapped (normally i guess by a EcuTek dealer/mapper). These two boost levels can be selected by using the throttle and the heater switch, as previously described.

3. Question --- Do Prodive in their PPP package make use of the EcuTek boost switching facility, allowing switching between two boost levels???.

Phew!

Thanks,

Chris.

 

Greasemonkey,

Thanks for the reply and feedback.

Cheers mate!

 

Greasemonkey

Are you sure???? My idea of 2 different maps is being able to make ajustments to timing, injector cycle, wastegate cycle, boost control, boost levels as opposed to just boost levels?

As far as i'm aware you cannot do this with Ecutek, it only allows low boost/high boost

 

Greasemonkey, cleared that up. Cheers!

Pock, EcuTek ECU, i was under the impression that ecutek was some sofware to map the standard ECU, hence my comments.

 

I think you are right in that they produce software and use the std Subaru ECU (?).

 

Yes, but this only applies to some cars. It's only the MY03 and onwards PPP that uses EcuTeK. The MY02 STi PPP uses a boost clamp type arrangement to reconfigure the wastegate control, and the classic shape PPP uses another method again.

Erm, no, sort-of. This isn't an EcuTeK feature as such. The dual map facility is part of the Denso ECU's core feature set from the start, so it's not like EcuTeK are creating something that wasn't already there. They're using something that was already there for a slightly different purpose than Subaru use it.

It's probably also worth pointing out that this is only a feature of the Denso ECU's that are used on the MY01< cars. It's not in the JECS ECU's used on the classic shape cars.

There's no information to indicate that they do. In any case, try not to call it an "EcuTeK boost switching facility", as that's a slight misnomer.

 

The ECU is a Subaru item NOT EcuTek. EcuTek have developed the software/hardware package to enable it to be remapped. Prodrive have developed the map.

 

could i get the ppp ecu in my uk300 remapped or is it better just to replace the whole thing. was thinking along the lines of the dastek/ unichip

andy

 

Sell the PPP part and get a std ECU remapped.

 

So if the standard ECU has two maps (manual and auto) is their any risk of running the wrong map, or is it fixed on installation.

 

Good question, and it's not one I'm privy to an answer to.

I'm not sure whether the map is set by a Select Monitor (or whatever equivalent Subaru use in the factory), or whether it sets automatically according to whether a manual or automatic gearbox is plugged in.

If the latter, then there's very little risk of the map being wrong. If the former, I'd imagine you'd still have be be extremely unlucky for a car to get all the way through assembly and testing without the nature of the fault coming to light.

Be interesting to hear an answer from someone who really knows though...
