mk4 golf gti t ECU

i own a mk4 gti turbo engine code AUM 150bhp, runnin a KO3 turbo, does any1 kno if i changed the ECU to a AUQ 180 bhp, would i gain any more power jst with that alone or would i need to change to the KO3S turbo aswell??

im pretty certain its the turbo u need to change !!! i kn ow that aint much help ..

Its the turbo, better off mapping the current ecu instead of changing it for another one. Standard turbo is good for 230bhp standard on its limits like, you should see in the 200bhp bracket with a decent remap.

plus u would have to code in the keys to the ecu..better off putting a ko3s and mapping it..with a stage 2 remap ud be looking at 260bhpish..stage 3 280ish

i would say u would get 260bhp i reckon around 240bhp mark!

on an aum...with a k03s and a stage two remap, 225-240 all pending on other bits you have...

AUM engines already have the ko3s mate, and drive-by-wire throttle instead of a cable.

indeed they do..the lucky sods...

ok gwd news, so my car is runnin a KO3S turbo , does this mean that the AUQ 180bhp ecu will make a difference and give me more power??

I got an AUM like you, which is fitted with a k03s as standard. I had it remapped a few months ago and it made 220bhp on the rollers. Only other mod was a powerflow backbox.
I got it done by R-Tech in hinckley, leicestershire - would highly recommend these people!

nice 1 m8, how much did it set u back??

my mums s3`s been remaped to 265 - its so much faster and less lagy than it was at 225 standard , if you can set up a BAM nt run that much power why not with a AUM etc? cheapest probs would be to get a tt / s3 loom?

I'll only tell you if you give me your wheels!

It was £250 including before and after rolling road runs.

They also have a mobile service where they come to you but obviously there's no RR included then.

thats a bargain, wana get lookin how i want it 1st then im gna start engine mods, couple more things to do 2 it!! its bin off the road for 2 weeks now, had the inlet manifold polished up, put new header tank on with sum nice new pink anti-freeze, new gaskets, new jubilees, gettin it ready for U dubs!!

Sounds good, is your car going to be on display at Ultimate Dubs then?

its on the vagwales clubstand in U dubs, ive got the car lookin kinda how i want it 4 then, jst tryin to tart up the bay with sum nice new stuff, jst seems like theres not enuff hours in the day to do everythin, ive only owned it since september an wen i bought it it was totally standard, nothin done to it AT ALL, so how u c it now, it has all bin done since then,
