Hey guys

Does anyone have any experience with PCIII's and the likes?

I've bought one second hand but it doesn't come with an O2 sensor/eliminator.
Do i need to buy the sensor/eliminator in order to get the PCIII working

Cheers

Mine does not have O2 whatcha call it, just straight in to the ecu loom and bobs your uncle. Mine on a gixer 600 k3. But I would ask this kind of question on a gixer forum :o

Ideally yes to enable it to be mapped properly. Ring Dynojet UK they will sell you one. You will need the code on the sticker off the back of the PC3 to order the O2 eliminator. They wont sell you one if the PC3 is a US imported one.

Just had a quote from YPE Power in Bonnyrigg to get the bike Dyno'd and a custom map put on my PCIII. At £180 it seems a bit excessive to me. That's nearly the price of a new PCIII.

I have no experience with Dyno testing etc. Is this a fair price or should I look elsewhere?

Yes and YPE I understand are very good at what they do. A new PC3 is more like £300, not £180 and id expect any dyno place doing the map properly will take around 3 hours in total to do it.

Its skilled work using expensive machinery. The investment alot of places like YPE make in staff and the dyno has to be paid for in some way or another. Learning to map properly takes alot of skill and experience.

Anywhere who says they can map a bike properly in an hour and charge about £60 are either not doing it properly, are just downloading a previously written map off another bike or are seriously selling themselves short.:cool:

Prices will vary slightly but in general most good tuners that I know of from the racing side will charge around that figure give or take ten/twenty quid.

That's great thanks,

As i said I have no experience with Dyno time and whats involved. £180 sounds a fair price after your breakdown above. I will give them a call and get it booked in.

Cheers!

No worries.

so let me get this right.. you think the 1000 is not fast enough that you have to put a PCIII on and get it mapped to go faster?

A good dyno operator should also take the bike for a test run and check things like throttle response and engine braking, which can't be checked on the dyno, and make adjustments post test run if required.

Not to go faster Lance, just wanna sort out the fuelling. I will never be as fast as the bike :o

I bought a Decat pipe which i've fitted and i've also disabled the EXCV. The bike is now running a little rich and popping quite a bit. Its idle hunting quite badly too.

I am hoping a proper PCIII map will sort out the fuelling and give the bike a nice power curve.

suppose its easier than finding someone capable of mapping the bikes brains. why did you disable the EXCV. suzuki put it on there to smooth out the bottom end and make the bike more ridable lower down. racers disable them as they are never in that range and it adds weight.

Suzuki only put the valve on the exhaust for homologation noise tests. It makes no difference to rideability.

They quite often seize up and cause a fault code so its just easier to disable the valve so the exhaust runs open all the time.

It kept sticking in the past and Suzuki GB replaced it as part of the warranty. Its now sticking again, so i've just disabled it and removed the cables and EXCV servo motor. I thought it was on there for noise purposes below certain RPMs for certain Europe zones :o

I bought the PCIII 2nd hand for £90, thought it was a bargain and decided to buy it. I think only a few places can reprogram stock ECU's so with the PCIII I can get a custom map from YPE

so its an adjustable baffle that serves no other purpose?

if that were the case then why have they been fitting these valves to bike before the stricter noise tests came into enforcement?

The Suzuki valve was only ever for noise testing for homologation.

Removal of the valve shows no real world difference to torque or power on the GSXR when run on the dyno, its not user adjustable other than you being able to adjust the tension on the cables so the valve operates within the correct parameters.

You can though hear it has been removed as it gives the bike a slightly deeper sound at low RPM.

They did play up as RamJam experienced and many were replaced along with the headers under warranty. Out of warranty they are just removed and the ecu pinned out.
