Question

Anything in particular i need to do apart from unscrew the foot plate, unplug the old, plug in the new, replace foot plate?

It's gotta be more hassle than that

Ah, doesn't it have to be mapped or something to avoid mechanical confusion? or is this a really naive and stoopid comment?

you may have to code your keys in if they are the transponder type.

recoding the keys only applies to the bugeye version. Classic shape is just unbolt, unplug, plugin new one, rebolt and away you go.

Am I looking at breathtaking performance gains here what?

Does the ECU require time to "Settle"

P20SPD - how and when would you recode the keys? First time I've heard of this. How is it linked to the ECU?
Gridlock Mikey - performance gains will depend on how the mapping has changed. Any change of getting it done at a rolling road? At least then you'll have some quantative figures on the change - run before, change, run after.

I assume you are talking about the AE801 ECU your are getting from me.
It is easy to install, just remove cover/kickplate thingy, unplug old ecu, plug in new ecu and away you go.

In terms of gains over the standard AE802 thats in MY00 cars I found it held slightly more boost and generally pulled much stronger.

I haven't recieved your cheque yet.
Regards

actually i've just the changed the ecu in a 98my turbo and had to code the keys. i believe it was a classic shape scoob as well so maybe we are talking about an import , i dont know if they have transponders or not. but i thought all uk scoobs from about 97my onwards had codeable keys.

On my MY97 dash there is a little key symbol that flashes when the car is locked. This is in addition to my alarm LED. I was told this is the key transponder light?

But.. if people have swapped out their ECU's without the key being rest then who am I to disagree

Anyone have a PPP ecu to fit a MY97?

Mike, if you want help fitting it, pop over.

I had to get to mine to solder in my AFR meter so know how to get at them

Although I imagine even you could do it
