Weird cos my F4i with a full Yoshi system ran like crap (especially low down) without a PC and a downloaded map. My 929 with a bolt-on end can ran better with a PC and a downloaded map too. My GSR-750 with an end can isn't that smooth either (especially without the baffle) without a PC in. Literally NONE of my bikes that I've had a PC in have been dyno'd, and they ALL ran better with it.
Is a dyno tune better? Absolutely. Is running exhaust mods without adjusting fueling in any way going to be better? No way. If you saw better results with a more flowing exhaust and no tune, your bike was too rich to start with. |
A Power Commander with an auto learn feature will be better than nothing, but you're still looking at this wrongly. What I'm saying is that a pre made pre downloaded pre baked map off of the internet could be any old guff. Even one for an identical bike with an identical system etc. I had a map for my Daytona 955i which was for a 1998 Daytona 955i with a Black Widow high level oval canned full system. Exactly my setup. I installed it on the bike using the Tuneboy software.
It felt better to me... but the butt dyno is notoriously inaccurate it seems. I had it dynoed a few months later at a dyno day, and the dyno operator said (and I quote): "That's the worst set up bike I've ever seen".
So I had it remapped properly and I managed to get my rather large quantity of horsepowers back.
Remember, bloke on the internet has supplanted bloke down the pub as the source of all dodgy information, and that includes 'premade' maps for 'standard' bikes.
I also realise the irony of what I'm saying, but what I'm advising people to do is to go to a qualified dyno operator and get them to set the bike up. There is really no substitute for it, even the Dynojet lambda sensor auto learn stuff.
That's what I mean about Schrodinger's remap though, I know it's perfectly possible to install a map and make a bike 'feel' better, but actually it's dropped 20+ horsepower off of the top end. ____________________ British beauty: Triumph Street Triple R; Loony stroker: KR1S; Track fun: GSXR750 L1; Commuter Missile: GSX-S1000F
Remember kids, bikes aren't like lego. You can't easily take a part from one bike and then fit it to another. |

I don't trust Lagunas so I've travelled to two other places instead in the past:
PDQ (Maidenhead)
Steve Jordan motorcycles (near Boxhill)
Both get a thumbs up from me. ____________________ NSR125RR - ZXR750H1 - ZX9R E1 - GSF600S - GSF600SK3 - VFR400-NC30 - SV1000N - ST1100-R - CBR900RR-R - GSF1200SK5 - GSF600SK1 - VFR1200FA - GSXR1000K2 - ZZR1400 D8F

This is all a PCV map is
Fuel, all values are percentages over stock. So if you changed all of those to zero it would be running stock mapping (with no adjustments from the Lambda because you have circumvented it)

and same for ignition

Now obviously if you are going to muck about with that at home you are guessing, similar to DIY playing with a carb (just with far more adjustment points). You can probably get rid of annoying emissions related flatspots but any power gains will be accidental.
A dyno though will measure the AFR and the software will generate trim values (the adjustments) at the given RPM and throttle openings to give the AFR that has been set, that AFR can be different at different RPM's, throttle openings and gears allowing a map to be made that can tailor to economy, performance or even both. The autotune works this way too (and can adjust "live" or not depending on what you want). If you want performance gains and have done the engine work to get them, then the AT or a Dyno is the only way you will see those gains. If you have a pipe and filter and just want to lose the snatchy fueling created by emissions legislation/testing then bollocks to spending 3/400 quid on dyno time or an AT, that's alot of money for a minuscule amount of power that you wont notice. I'm cynical so I'd also say keep in mind Dyno operators want to make a living so they are going to trash talk AT's and canned maps (and with canned maps I mean from the DJ website or known specialists for a given bike, not bloke on internet).
There are further things the PCV can do, most notable is you can extend the rev limiter, great way to blow up your motor |
