Boost contoller

[WASPY]

HI
I am thinking of putting a electronic boost contoller on my cupra, but was just wondering if this cause any problems. would this also bypass the n75 valve. can any1 recomend a boost controller aswell.

Thanks

what turbo do you have!!

I have the standard k03. With jabba stage 1 fmic forge tip and induction kit.

pointless. i've just get the ECS n75 race valve to up boost a bit. ECU will kick up a fuss more then likely and go into limp mode. it'll just detect overboost

yeah, no need for it unless you're 100% aware of what you're doin.... Even then, I don;t think anyone on here has one on their ibiza? (correct me if I'm wrong)

 

[cus]

a couple of people do, and i know dicko who had a 330bhp ish Leon Cupra had one.. but all depends on the mapping i guess, and if its running something like DTA, then i guess the ECU wont throw a fit

loads of ppl have done it. and its a good mod if your going to be going high up the bhp line.


just dont do it if your not planning on going big power.


i think phil has somehting like this on his and he is only running 230-240 ish. (was when fitted first)

Greddy Profec B2 on mine, Apexi ACVR on jonzy's and they work fine, just keep the N75 plugged in electronically and use the controller to regulate boost.

If you do hit limp mode for overboost (which my car has never) just dial down the boost. Simple.

i have got an electronic boost controller on my KO3. It was fitted by jabba along with their stage 2 map. i only have 205bhp but the torque is at 323ft pounds

I dont think so.

 

[mr_D]

proof! lol

 

[mr_D]

mind you phil i have seen 220bho ibiza with almost 300ftlb. but i do agree with you it does seem a bit distant and far fetched.

 

[Mat]

what's the benefit of having one?

Is it a case of running silly high power, then "de tune" it for road use etc so it (the turbo) lasts longer?

Phil, do you have the setup instructions for your Profec you could send me?

 

[PhilW]

Email it to you bill? Or PM?

Bill, this is what i actually posted in jamiebennetts topic a while back.



Change the units to psi for a start, so you know what your looking at, i use this more than my boost gauge now, it will tell you how to do it in the manual posted below.

What i would do is start with the Set at about 50% (set is wastegate duty) and the gain at 0 or the lowest it will go. Then put your start boost at about 12psi. Start boost is when the control takes control, ive never worked out why they say to put the start boost close to your desired boost, i always seem to spike that way.

Now you'll probably hit around 13-15psi i reckon for this, then just adjust the Set boost upwards and see what it spikes to. You might find it doesnt spool that quick, in this case raise the start boost up.

For me the gain did nothing apart from causing my boost to fluctuate. If your boost does go up and down along the rev range then play with the gain, if it doesnt leave it at the lowest setting.

I find the only two i play with is the set and the start boost.


My settings are:

High boost:
Set: 83%
Start Boost: 14.5psi
Gain: 5% (the lowest)
Warning 24psi
Limiter: 4%

This gives me a spike of about 23psi and holds around 12-13psi at redline.

In the manual they say to have your start boost close to your desired boost but i always found it would spike like crazy at this value.

So should i just go with the race valve. I am planning to do a stage 2 in the future.....

 

[PhilW]

I wouldnt bother if you're not gettin any problems.

 

[WASPY]

Well the problem is that i have got boost promlem it is dropping like mad the higher the revs go has any1 else had this problem.
