Hi people im purchasing a prodrive ecu today for my99 uk ive read in old post from years back that it seems theres a risk i could end up messing my immobiliser and alarm up by swapping the ECUs over ...........?? But the guy selling said its plug and play and also some of the other members have said iut literally was a 5 minute swap over and had no problems at all........ can anyone give me a definate answer as dont want to waste 200 quid on something i cant use and if it means going to dealership and spending loads moretowards re-coding etc i shant bother.......thanks

 

I really wouldn't do it if i were you.

Have you spoke to one of the mappers yet i.e JGM or Duncan@racedynamix

I can't imagine you'll see much if any difference by swapping them over.

 

Just the ecu alone is not plug and play on the MY97 car for definite. I think it is the same on the MY99

It is plug and play if you have the matching immobiliser box and the transponder chip out of the key. Have done it on two different MY97 cars no problems.

To make full use of the ecu you will need
1) decat centre section
2) Prodrive (or similar) back box
3) Silicone Y pipe from turbo to intercooler
4) run it on +97 ron fuel
5) there is a query regarding the size of the restrictor pill that assists controlling the boost.

This was a good cheap mod on the pre 99 cars that could not be mapped at the time and achieved a respectable 250bhp ish with a nice hike in torque, slightly better fuel consumption and the ability to pass an MOT.

But the MY99 car can be mapped on the existing ecu and you will probably get better value for money from this route.

Good luck

 

Save the £200, then keep saving a couple of hundred more and have the current ecu mapped.

 

thanks all for the sound advice just going tpo save up a little more and have one of the pros come out and give me a map on te standard E3 ecu ..........will it be safe to drive my car de-catted until i mapp the car????? just waiting to april to pass m.o.t then the cats coming off i have cat-back at moment

 

just been on jollygreenmonsters site id rather pay him 5-600 quid and have a proper map and a pro.s work.

 

In theory all being well (maf and fuel pump good) it should be safe on decat.

Can be checked to be sure.

 

ive never had a problem with maf and i have standard pump would u reccomend a walboro pump before decat and map?? or will i be ok just de-cat and map

 

i havent even seen a picture of the ecu which i have reqeusted ,so im not going to take the risk when i could save a little more and have a man on site doing a map and is a expert .thanks for your reply
