All you've done is fit the Ko3s or something over and above?

AUMs come stock with the ko3s, I think he is thinking about the benefits of mapping to stage2 with the ko3s? 

@porter

They will flow just over 240bhp, limiting factors are, charge cooling, down pipe, flow and actuator condition.

Lol
 I had a customer come in the other week who was over the moon that he had just fitted a ko3s to his AUM and was looking forward to 210bhp from a spec1 custom map,  he won the turbo on eBay for £260 and thought he got a good deal.   But then I told him he had took off a good ko3s and replaced it with another identical ko3s.  Not too bad you?  Then he tells me he sold the old ko3s which he thought was just a ko3 on eBay for £45.

The only thing is some early AUM's actually come with a Ko3.

Some more info here in case you're in any doubt.

I am not in doubt at all  :wink:

All AUMs are K03s even the very first 887-128 revisions late 2000 (which mine is, one of the first of the production line), the only post 2000 DBW car running the K03 was the ARZ and later reg AGUs
Some of the early k03s units looked identical to the K03 by having the same comp external housing casting, then later on changed to silenced version which most people claim to only be the k03s. The people on um-mkivs where only going by the visual look not the comp hosuing cassting number or the KKK part numbers.

That's interesting mate, to be honest I haven't come across any early AUM with Ko3 anyway - just saw that while reading up.

Even the k0-001 has the same casting as the k03. 
Some old AUMs will only make around 190bhp due to the actuator spring getting a weak over the years, and the blocks 114 requested and actual load dont meet and the n75% is at 95% all the way over 3800rpm, in this case around 4-5 turns of preload on the actuator will bring the power up, or if the nuts are seized you can bend the actuator mount back by 5-6mm. If the spring is too weak the a new actuator is needed.

The ko3s will flow around 240bhp, but this all depends on how the air is getting in and out the engine, the better the induction, tip, fmic, and turbo back exhaust the better the chance of getting the power. I have not managed to hit 240bhp on an aum with all the oem PVC and n249 in place so would be a good idea to do the catch can mod and vent to atmosphere so the breathing of the vapour don't reduce the octane rating of the fuel.

The major factor to getting 240Bhp is the actuator being weak and worn, a spec1 remap should peak at 19psi and hold 14psi, but when running stage 2 peaking upto 22psi and holding closer to 17-18psi a weak actuator causes the waste gate to creep open and bleed the power off. The cure for this would be a forge actuator with yellow or blue spring and have it mapped correct.
 If its running well then you could see 265lbft

I hope this helps,  back to back k03s graphs stock - r-tech spec1 and r-tech spec 2

I will get some 001 runs back to back with a strong ko3s run.
As for launch control this comes free in the 001 custom mapping, along with our unique linear throttle maps, rapid shot rpm limiters, left foot brake option, wot flat shift mapping and our new light load fuel stratergy mapping so can see around 44mpg on a good run.. :-)
There ain't any other map out there will some much crammed in to it.

regardless of being linear or transverse, what are the differences between K04-001 & K04-015?

which is going to be quick day to day?

right plans change again cba to change the tuirbo but will be doing these mods

ko3s with forge actuator
turbo back 3" exhaust
larger cooler like wazzer
new maf
uprated inline pump
what power can be gains from stage 2 with these mods

cheers

Hello,

The we gave 100s of emails and back logs each week, the best way it to call us or call and leave a number for a return calll back. Long winded pms and emails get put on the back burnet until I cam sit down and answer them... Then time is the issue... Ain't enough hours in a day.. Lol  ben answers all the basic emails and Ron and jim do there best with the phone calls,  but I am the only person at rtech that carries out stage 2 / custom mapping which means upto 6 hours a day on the dyno.
