PCV on RSV4 (factory)

[mikef4uk]

I fitted my PCV and Autotune yesterday, it's by far the most time consuming PCV I have ever fitted, the variable trumpets, upper trumpets and complete airbox requires removal for the lower injectors.

For the upper injectors the fitting is quite easy until you try and refit the tank, there just isn't the room there for the original injector plugs to be now plugged into the male plug from the PCV.

Try as I did I just wasn't happy with the fuel tank putting pressure on the inj plugs, I would imagine a non factory may be easier as on the factory there just isnt the room for the two front cyl inj plugs and the variable trumpet plug unless your happy having the tank resting on them, so I bit the bullet and chopped them off and soldered the wires together, finishing off with adhesive lined heat shrink, much better job.

Today I set the fuel target at 13-1, the % fuel alteration at 20% and went for a run, after 50 miles the bike is running very sweet, I tend to try and do the following:

Hold throttle slightly open in 3rd at low rpm, and just let the bike run out of revs, hold it a little further open and repeat, eventually you end up with the thing on the stop.............That gets interesting!! I guess this is the same procedure as on a dyno.

I then accept the trims onto the main fuel table and alter any that look out of place as e.g 4, 5, 6, 8, 12, -15, 12, 11, 9, I would alter the -15 to 12, luckily there were no such values this time.

The bike is now running as it should throttle is seemless, NO flat spots or dips it just accelerates smoothly and progressivly, this was the 1st run, it will get better and better with subsequent runs and i'll probably raise the 13-1 a little in the lower rpm and smaller throttle openings, may also reduce it to 12.8-1 in the upper rpms and large throttle openings, very happy

Would be lovely without all the connectors...
Did the Bazzaz last year, and it's a pain to locate the connectors properly.

What happens when you swap maps?

Ive heard almost nothing but problems with the self tunning piggy backs on other bikes, good look. Hopefully you get a tune you like & save it or disable it so you dont loose it or it gets changed later.

What happens when you swap maps?

It shouldnt make any difference, the PCV looks at the throttle blade angle against rpm (not twist grip angle) and adds or subtracts fuel as req,

once the autotune (you change the lambda for a wide band one) has finished it's map (which could take a while) I will narrow it's permitted adjustment range to probably +/-5% and just leave it fitted, think of it like running closed loop all the time except I set the target A/F ratio, on my S1000RR the fuelling correction would alter from +3 or 4% to -3 or 4% depending on the temperature of the day, now I know ecu's are programmed to do that but it was noticeable that the PCV was making corrections as well

To be honest I have used a power commander on all of my bikes for the last ten years from PC to PC111, to PC111USB and now PCV, I hope i'm not going to regret saying this but (touch wood) I have never once had any problem whatsoever

I would'nt have believed just how smooth this bike could run after just the one 'run', it will only get better as it perfects the map, it even sounds different on idle

I agree, would be lovely to swap it out for a Microtec ecu, which was in development until Aprilia brought out the aprc bit ( at least that's what I was told by an MV tuner who fits lots of them on MV's)

PCV connects to upper and lower injectors (two modules) engine crank sensor and two wires going to the ecu

He makes real good gains with ignition timing and also altering the rpm at which the intakes lift.

Have you installed the latest aprlia map that just came out a couple weeks ago?Thoughts?

No I have'nt Chris, but as good as it may be it will still be targeting very lean A/F ratio's in the closed loop emission testing part of the ecu (where you probably spend 90% of your time)

I also don't understand how the USA and Europe 'race' maps can be the same? USA ecu'sgenerally run around 10% richer than European maps due to the difference in fuel

Hi Mike
Did you buy a Race ECU too?? Very interested in your results...)

[aarfeldt]

Btw - does the PC5 kit include a plug for the empty Lambda-connector ?

[tattoo]

a question from me too on this...

the pcv is compatible with a quickshifter,right?

if yes,the type of the shifter depends on the rearsets (oem ,gilles etc)?
(like gen 2 rsv?)

i m planning to buy a rsv4 factory,which has on a race ecu (i think) or I dont know if it is the same thing, an ecu to which I can load maps..

i was going to put a pcv,shifter if possible and do a custom map..

[mikef4uk]

No plug for lambda sensor socket, instructions say to just unplug and remove the sensor if you want, i have taped it up just to stop water and crap getting in it.
The pcv does not effect the std quickshifter, there is also a dynojet qs if needed

No, after talking to Aprilia about a race ecu or unlock code, if they here of either they stop your warranty apparantly,

I have the autotune as well, whether I will put the bike on a dyno I am not sure yet, the AT is making the map as I ride, the 7000rpm hole that people talk about had gone, the AT is now adding 20% more fuel at that part of the map.

The only bad thing about the PCV is fitting it, what is usually a quick job is a nightmare on the V4

How can they void your warranty as a result of you fitting something they themselves sell?

Certainly there is no suggestion of anything like that here in Oz - mine is going in tomorrow for new camchain tensioners under warranty & it has been running an unlocked ECU since I picked it up from the showroom floor.

[ckruzel]

i have the race ecu, i'll be installing my PC V over the winter, can't do a run until spring time though or unless we get an unusually warm day

i haven't heard anything bad about the autotune, i got one also
