Wunderlich or PCIII?

[Beemerman59]

For an '08 GSA with Remus headers, Akra can and accelerator module.

I want to achieve two things mostly - most importantly to smooth out the engine at low revs as it still is erratic when slow speed manouvering resulting in constant hovering on the clutch to catch it. Secondly to give me piece of mind on the lean fueling as I love the bike and now intend keeping it for a long time.

I believe both of the above have standard mapping and extra fuel can be dialed in across the rev range in a manual fashion. I don't need any real tweaking other than mentioned so I'm hoping not to have to have it dyno'd as the cost just goes out of the window for me, hence the two choices.

Cost seems about the same, so does one have any other advantages over the other in the real world when using just the base product? The Wunderlich retains the O2 sensors, the PCIII doesn't - is this a deal breaker for any reason?

I bought the PCV on impulse and am now thinking I should have gone with Wunderlich, as, having installed the PCV, it leaves the unplugged O2 sensors exposed to the elements. Also, although I'm getting a much smoother response in general, after extended rides the engine idle is so slow the bike keeps stalling, and in order to fix this I have to switch the ignition on and off - simply pressing the starter again won't get the engine going. I think this may mean I need a custom map, though, and hopefully this will stop the problem.

Like you, I'd be interested to hear other people compare the two systems.

I've run both of them on my 07 GSA,
the Wunderlich PC I had on 1st and had some good results with it, it's very easy to use and deffo makes a difference.
Due to an unrelated poor running problem that reared it's head I bought a PC3 USB to try to dial out what was thought to be fueling problem (it turned out to be the 2ndry coils ) and changed over to that.
the PC3 (and V) is much more adjustable and gives you the ability to split the two cyclinder maps if required, and fine tune it to within 250rpm increments, where as the Wunderlich is a tad more generalised.
theres little to choose between then in terms of quality ( i thought the lock tabs on the wunderlich were poor but then the waterproofing of the Powercommander left a lot to be desired.
the Wunderlich for plug N play no problems, the PC for if you want to play around more or have more variables in the equation, thats my 2p

If you're concerned about the lambda sensors, remove them and replace them with threaded blanking plugs.

However, since you have a PC V, you can add the Autotune module which adds wideband lambda sensors and will remap the fuelling in real-time.

In the end I have opted to buy the Wunderlich option. It seemed a simpler solution for me and as I don't want to spend anymore on dyno runs etc I think it will do for me.

Fitted it last weekend and was pretty straight forward. As it works in conjunction with the O2 sensors and the ECU I think the installation is really neat and from the point of view of "peace of mind" I prefer this method to the PC method of removing the sensors. I'm sure it gives me less room to tune the engine but then thats not why I bought it.

I did have the Accelerator module fitted with the Remus headers and Akra can so when fitting the Wunderlich controller I removed that and took the bike out on the mapping that equates to a Cat free header, non-OEM pipe and a Blue air filter - I guessed that was close enough although I'm on a stock filter. The bike ran extremely well in this mode. Just to try it, I put the Accelerator module back on - the bike runs fine, but there's a little hesitation on hard acceleration. I'm wondering if it's now too rich in open loop mode so I will take it back off this weekend and stay on the base map for a while until I do the 24K service.
