Ecu upgrade

[leigh4x4]

Hi all, I'm thinking about upgrading my standard 4 ecu to a 5 for future mapping. Was just wondering if this upgrade is just a straight switch. E.g unplug the 4 ecu and plug the 5 straight in. Any info would be appreciated. Also anybody know where I can get one? Cheers.

hi leigh yes the 5 and the 6 ecu are both just plug straight in you could try sponners he usually has thats where i got my 6 rs ecu from and he is great to deal with

failing that try el , jamie or john@evobrakers there are a few traiders on here that will soon sort you out bud!

dont forget u also have to change injectors!

Thanks guys. I've been doing a little research. Am I right in thinking that I would need the ecu,injectors and walbro fuel pump?
Forgive my ignorance but this is all new to me. After changing these parts would I need to get it mapped straight away? Thanks

You'll also need injectors from an Evo 5-9. I have a set for £50 if you want them ?

5 ecu is plug and play BUT the 6 ecu you have to cut a wire/swap a wire.

Spot on

Get it mapped ASAP as your fueling will be all over the place. At least check the AFR before any real driving.

Yep deffo get the mapping checked by a specialist

Sorry for the off topic but how's the rs diff conversion coming along tan ?

Thanks for the info guys and Lee. I might take you up on the offer. Would like to source the other parts
Aswel if anybody knows of anything available.

Still saving m8 but what with christmas etc things are on hold till new year.

Hope to have one on by Spring action day at combe

I might be able to source a 5 ecu also mate

 

[chrisevo4]

just fitted a evo 6 rs 2 ecu and injectors to mine and fuel pump my mate i got it off still has i more evo 6 rs 2 ecu and they do just plug in.:razz:
ecu £100:whistling:

 

[sponners]

95% of the time the 5/6 ecu is just plug and play.......only a couple of wires to swop if it doesn't work.

a lot of people just run the ecu/injectors without even getting a remap and seem to be fine.


if you do decide to get the car remapped then you dont need the later injectors.

 

[B6lee]

thought the injectors had to be upgraded regardless ???

 

[sponners]

the standard 5 onwards ecu is fully programmable mate, so you can fit whatever size injectors you want if your getting it remapped.

but on a standard 4 engine the standard 4 injectors are more than capable.

 

[leigh4x4]

My cars pretty standard. The only mods are kakimoto exhaust (cat back),greedy downpipe,hks Ssqv dump valve and hks mushroom filter. If I were to change the ecu,fuel pump and injectors and get a map does anyone know what sort of bhp I would achieve? I'm just trying to weigh up if it's worth it. Thanks again.

 

[Tan]

Might be worth thinking about a boost controller or if funds are short get a 3 port solenoid fitted when you get in mapped

I think you can run up to 1.4bar safe.

With the mods you have plus the up-grade you should see 330-350 safe.
