- Smooth on/off throttle - 99% fixed (bike is much safer)
constant throttle - easy to maintain speed
acceleration - drastic increase, and more responsive
jump to sections by clicking time
@0:00 - no PCv - snatchy throttle
@1:05 - no PCv - jerky constant throttle
@1:47 - no PCv - 4th gear 60-130mph
@2:20 - with PCv - smooth throttle
@2:57 - with PCv - easy constant throttle
@3:35 - with PCv - 4th gear 60-130mph
60-130mph (7:19sec - 6:00sec)
Acceleration tests are done on a closed course.
Tests were done at the same air temperature, same
stretch of the track, same time of the day, same fuel
type, same fuel load. They are unscientific but prove
the point.
At the end of the day the bike is safer, faster. Its
better on the track and on the road.
I installed the dynojet on the stock bike with the preinstalled map for the gsxs1000
Even as a commuter and track goer with plenty of experience... i could handle the issue but would rather not.
I have no affiliation with dynojet or anyone that works there but thank god for these guys....
Finally a very clear video about the difference. Good job!
I purchased the pcv for my 2016 gsx-s1000,and it works great, no more snatchy throttle and really smooth torque curve as well.
If only all TH-cam posts/conversations would be so informative! Thanks again.
thank you. This was a make or break for me so i wanted to share with others.
Great Vid; will be ordering PCV for my 2016!
I got the 2018 z version and the snatch and constant speed is still evident especially with a bit of chain stretch it's almost impossible (dangerous) to ride slow in traffic. The 2019 is out and the dealer is putting PC V's on before selling with after market yoshi pipes. I've ordered mine and hopefully it will fix the problems 99% as you say. Also putting a G2 throttle tamer on it.Thanks for your informative video, it's still relevant several years later.
gee bee you’re most welcome. Most bikes benefit from post factory tuning. This applies to all settings. Suspension, bleeding brakes. Alignments. Etc.
Great video that is showing the problem..
thank you. I was worried it wouldnt translate into a video but its so evident i had to share.
So the problem is as bad as everyone makes it out to be. Glad to see the PC V fixed the problem.
yes it really transformed the bike for me.
It is fixed on the 2018 model. At least as far as I can tell. No problems
Great video with great details!! 👍🏾
hi sorry beacouse my english is not very well but a have simple question
can you tell me did you buy and install PCV only ? or install PCV and doing something with ECU ?
I cut my pipe decat half and install Leovince LV pro carbon . And now i have little hole on a middle rpm and also snatchy throttle like you.
If i buy PCV and connect that will be enough ? i saw on PCV site some Leovince slip-on map to PCV for gsxs 1000
THX
deebasny hello, only the PCv. For this video I didn’t even download a map. It was the default map. After this video, I have installed a full exhaust, flashed the ecu (to remove some limits) and built my own PCv map with autotune. Cheers
to better help you... I wanted to say that the fuel map that you download or make yourself (with auto tune or a professional dyno) is based on the air intake/exhaust of your bike. The video I posted is for a stock bike (intake/exhaust) and with the default fuel map on the PCv. Since you changed your exhaust you will need a different fuel map. Likely to add more fuel. Hope that helps
@@hellomihai ok thx
@@hellomihai my bike has accesory exhaust and decat.If I buy just pcv and instal map from their site will be safe to engine or I should make remap ( add more fuel) ?
@@Gruby_Fasol i recommend you check their site. They have many maps for different exhausts so maybe you can find something thats close. You can then either take it to a dyno shop (expensive but good), or get an autotune (i have and am happy) or just edit the map yourself but youll need to learn how (which you should anyway). Hope that helps
I read on a forum that the pc fixed most of the problem but it's still bad. Thanks for showing the proof
hmm... there might be some truth to it. Maybe it doesnt fix allllll bikes... since theres build variations... but maybe the people put bad maps on their PCv?
thanx for the video, will be getting soon
bought mine in April '16, throttle has been perfect since day one.
thats great! Youre one of the lucky few... some bikes dont have the symptoms at all.
Will the standard map that comes with the power commander V fix the issue? Or do you need a custom map?
good vid! Just got a gixxer 1000 year 2004 and the power commander seems to be exactly what I need since it has an after market exhaust and in low rpm spits and sputter...
the spits and sputter are also due to the PAIR valve. You need to block it. TH-cam some videos on that. It shoots extra air into the exhaust to combust unburnt fuel.
great video dude. i sub'd just cuz of the way u responded and informed people in the comments. we need more youtubers like u homie! what part of cali u from? im from the Bay Area. Go Raiders!
Skottie delago thanks bud :)
Great video, Now I know that the pc5 is worth the money . Thanks
:-)
Great video!!! Best explanation I’ve seen so far of the problem!! Kudos
Do you ride with the traction control on after adding the PCv?? I’ve seen people saying the TC and PCv would fight each other... again, great video!!! 😀
I ride usually with the TC in lowest setting just for wheelie control. But often turn it off 😜
Hello Mihai 😀
awesome guide helps me allot now i know what throttle means i had that on my R1 2012 bigbang motor now i gonne get Suzuki gsx s1000 2015 is that a good bike? greets from netherlands
I had my ECU flashed. Same result. 140 wheel hp before,146 wheel hp after. Torque 103nm before 109 after
Flashing ecu and releasing more power makes it more jerky. Adding a pc5 helps tame the on throttle more. For a really smooth throttle I recommend stock flash with a pc5. I first did the pc5. Then the flash. Then full exhaust. Then it was really smooth.
@@hellomihai I think i misspoke as english is not my 1st language. I realize now that my bike was MAPPED,not flashed. I have no idea what the difference is but... I dropped the bike off and picked it up 6 hrs later and i couldn`t believe it was the same bike i dropped off that morning
On second thought, it's an issue for me now. Looking at getting a PC or something soon to help with mine.
+Brandon Bicasso here has to be a modification to the fuel map since emissions is so tight Suzuki couldn't make this engine pass and still be smooth
is it custom map for your bike ? or stock map from dynojet website ?
stock bike, with the map for my bike from power commanders site.
The GSXR riders have this also, just to a lesser extend. They tend to move the TPS upwards to fix the snappy throttle. Its called the 'herky jerky' or something in the forums. Perhaps that can benefit the GSXS also? I have had the same problem with my GSR600 K9. Now on a GSXR750 K8, not that much on the foreground. Perhaps I will also adjust the TPS.
+Jeasy TH-cam yes adjusting the tps (throttle position sensor) helps but ultimately it's an emissions problem that Suzuki fixed with a crappy fuel map. Need to fix the root of the problem.
+Jeasy TH-cam yes the forums recommend the same but this fixed it for me.
I have a 2016 GSX-S 1000. Just bought it brand new out of the box. I had Full M4 exhaust, K&N air filter and PCV installed. The bike doesn't like riding around town especially around 2-3k RPMs. Dynojet only has one map and its for stock exhaust. Did you have someone build you a map? I only have one option for DYNO near me and he starts at $400.00
Hey congrats on the new bike. Instead of the dyno i would recommend finding a map that is similar to your setup and just buying the auto tune. A dyno map is static. If you use different fuel, or ride up to a different altitude your map wont work well. Thus an auto-tune will be really good. And allow you to build a new map (albeit slow) if you do any other modifications.
remove the 2mm of throttle play = no snatchy throttle.
Not quite. This is an issue caused but a very bad fuel map meant to pass strict emissions. Also theres a fuel cut off thats too abrupt exasperating the issue. A pcv or ecu flash is needed to get at the source of the problem and the bike STILL passes emissions. Suzuki just played it very safe with this fuel map...
thanks for replying.. I'm really am interested in getting this bike but was on the fence with all the reports of the snatchy throttle but it seems like u were able resolve the issue with just the pcv alone... still don't like the idea of the hassle to fix a bike that's brand new...did u install the pcv yourself? I'm not really experienced with working on bikes, not sure how much it would cost me to have it done or if it's something I could try and do myself...
Im pretty experienced but its really not that hard of a job. You also have the option of removing the ecu and mailing it for a reflash... just choose someone that does a woolrich flash like schnitzracing. Also how cheap these bikes are to the competition s1000r and others its very well worth it.
I have a 2016 model too.I didn't fix it and it's ok.You tend to get used to it.The problem.i have is when riding in 1st or 2nd gear and keep it steady.Thatxs when i don't like the AFR.It's running lean in my oppinion.I plan to instal PCV too but not for the throtle as much as for that 1st and 2nd gear steady speed feeling.
Why is everyone calling this an issue? The instant throttle response is a common trait with Suzuki bikes.
its not just instant but a very hard snap. Stress on the chain, tire and most importantly very unsafe to open the throttle in a corner. Had several slides on the track due to this and after it was a much safer ride.
+Hello Mihai I understand. Good that you got yours situated. I think I'm just used to it with mine.
No, it's not "instant throttle response." It's very lean fueling which causes surging. Add to that sloppy throttle tube cables and you got a mechanical bull to ride.

Looking at one of these next year I think......... Do you think that an ECU flash would be better than a power commander as I have heard that you can make changes such as exhaust, air filter etc without the need to change anything on the ECU
ecu flash is good for removing certain limitations. Top speed, timing, when to open the secondary flaps, fuel cutoff (which helps with the snappy throttle) but the PCv is the one that allows you to adjust fueling for whatever changes you make on the bike easily. With an ecu flash, youd have to flash it each time and youll need a dyno and a really good tech to get the air:fuel map spot on. I dont like being dependant on that so i got the ecu flash for removing limitors and pcv+autotune for the map.
@@hellomihai awesome 😀👍 thanks for the info mate
Sure thing. I struggled with this since I hated the bike at first so Im happy i found a solution and wanted to share it.
Very good video ! I have a 2018 model and there is still some throttle issues. I would like to order a PC but I've heard that the gas consumption is increased also. Did you noticed it ? (sorry for the poor english)
i honestly dont mind a % differentce in the consumption... you are riding one of the biggest motors on a sport motorcycle... but no I actually saw better gas mileage in my case.
Does it increase BHP as well as smooth out the throttle . Great video man . I've just bought a 2019 gsxs1000 f so want to upgrade to PCv .
Dylan O'Sullivan Yes you get extra horsepower but mainly torque. Most of the performance comes from exhaust.
Dylan O'Sullivan Mainly for me I didn’t care about the extra power. But what I did like is how much more instant and the throttle feels but not snatch it. Excellent combination
@@hellomihai thank you ,yes your right it's got plenty of power anyway but if it smooths out the throttle that's a massive bonus . All the best mate 👍
Hi, is not there any official fix from suzuki to throttle issues? Thanks for uploading this video.
Carlos Lavers Hernández no solution from Suzuki since the cause is emissions regulations which are forced upon Suzuki.
Hello Mihai, thanks for answering. Its hard to believe suzuki is not able to fix it. What about other brands? They do not have this problem with euro4. I think its only an excuse from suzuki.
well yes and no... suzuki is not unique in this problem (motodna.net/jerky-motorcycle-throttles/)... one of the worst bikes is the yamaha fz-09... and there are many more. The fuel mixture is pushed to the limits so the emissions pass. Other manufacturers like bmw have better solutions but are more expensive. My video is to demonstrate taking a suzuki which is more reliable than a bmw and with an easy modification, smooth out the throttle, and release a lot of power. Cheaper, more reliable... Win.. win...
Hi, also an owner of a GSXS1000 with PCV. By any chance did your miles until empty function stop working after installation? I noticed you switched to MPG in the PCV installed portion of the video. Not really a big deal since everything else still works, even the fuel gauge. Just curious if I mightve unplugged something by accident.
+Chad Higdon hi, no I didn't have anything not work. Only thing was the abs which came on after some riding around. It might take a few miles and it should come back. Take it for a few more rides.
Hello Mihai you are correct sir! thank you for your reply
a question did you get a o2 optimizer in the powercommander 5 box i get none in my box for disable the o2 sensor a white little cube thing with a green bypass wire in it
JoelG initially I just got the PCv. So it had a stock oxygen sensor block off. Later I got the auto tune which came with its own sensor but it required a larger bung hole. So I had one welded. I have aftermarket headers so I did that at a local shop when the headers were off the bike. Cheers
yo mate do you know if gsxs 750 have the same problems? And is it true that if u have slip on exhaust PCv will not perform well or are those just rumors ? ty
hey, not familiar with the 750. But a pcv is meant to fix fueling issues by applying a map. Any changes you do on the bike will make it run not-optimized. A pcv allows you to get it back on an optimal path. Essentially i would recommend a pcv for stock and especially for mods like exaust
So this is a plug and play from the factory with the stock map already downloaded on it? No hooking up to a comp and shit? If so, hell yeah. I'm not looking for any performance gains, just a smoother throttle.
thats what i wanted as well... bonus is more power but thats because the engine runs better. Yes you dont have to mess with it. I bought it and just installed it on the bike. Started it up and ran well.
Hi. Did your fuel economy change with PC installed?
Yes the bike was a bit more efficient and ran a tad cooler.
With this fix, the gsx-s becomes much more attractive.
I only considered this bike with the PCv. Without it its a slave to the emissions tune which Suzuki had to put on it. Since the bike is so cheap to the competition, adding a pcv is very tempting and has amazing results. Add a full exhaust and air filter and itll put down a lot more power than the competition.
This page explains what's going on with this bike. Factory fueling at partial throttle is garbage. Easily solved, though.

I've heard of the power commander for years and even tried googling it but there are so many different products, it's tough to know what to look for. What does the PC V actually do?
it remaps the fuel to air ratio at different throttle positions. This link might help th-cam.com/video/CjqTFXRdNJY/w-d-xo.html
It jerks back and forth with no throttle, I don’t believe it help at all
what point in the video? The beginning is showing the problem with no pcv
did u get the bike dyno tuned after installing the PC v?
I didnt... i either could have had a ECU flash with a dyno visit or the PCV with an autotune (coming up soon). So I put my money on the PCV since its a bolt on and if something goes wrong i can take it off.. but with a bad ecu tune youre kinda stuck and to change it again youd need another dyno visit and adds up.
Hello Mihai.... there are some reflash companies who offer unlimited additional flashes at no cost beyond the first flash.
Why can't the OEM module be remapped to address the snatchy throttle?
you can reflash the ECU but I much rather have something external that I can remove is something goes wrong and its easier to modify without needing a dyno.
Except a fuel module simply modifies the signal sent from the ECU, changing the fueling. It is a good start for fueling issues, but most factory bikes have a lot more issues that a piggyback module will never address. Change the coding at the source and everything gets fixed.
An ECU reflash does a lot more:
Improve Fuel & Ignition Maps
Eliminate Factory Throttle Restrictions
Optimize Throttle Maps
Eliminate Timing Retard
Increase Rev Limit
Remove Factory Top Speed Limiter(s)
Eliminate Factory Fuel Cut
Optimize Off-Throttle (Decel) Mapping
Lower radiator fan trip-on temp
Disable Factory Error Code(s): Exhaust Servo Motor/Valve, Pair Valve System (Smog Valve), O2 Sensor/Lambda and more..
That reply gives me better questions, thanks. Who does that type of work - well - being the first question that comes to mind.
Depends on what model motorcycle and where in the USA you live. Most shops have a mail-in service, just send the ECU to them for a flash and they return it. Plug and play. You specify the sort of hardware changes you've done, the make and model and year, and they apply the changes. If you want to leave the fuel changes to a module, I recommend doing the ECU flash without the fuel changes and adjusting the fuel with a module at a dyno shop.
Some motorcycles have a much worse time from factory than others. Some can benefit a lot more with a full flash, others you will notice somewhat less. The cost of flashing depends on the shop, and how much work they are doing in the brains. All of that is negotiable with you the consumer. Some offer unlimited reflashes if you should need them later for adjustments, or for further hardware changes. Some require a small fee for reflashes (including flashing back to OEM stock).
I recommend schnitzracing.com for ecu mail in service. They do great work.
hi... good day. i installed pcv and autotune on my bike as well as arrow racing collector and muffler but snatchy throttle still exist.... can you help me sir what to do to iliminate the problem?
+youdrpatulot hi. My setup was the first ecu version (not the one replaced by suzuki) located in the US. If you have a different setup I recommend trying a few maps found on dynojets website and see which one helps. This is for sure a fueling issue. It was a clear difference for me and I really would refuse to live with the bike the way it was before the pcv. Currently I have no snatch at all.
+youdrpatulot also check gsxs1000.org for more reading material on this matter and more opinions.
+youdrpatulot also check your TPS setting. Some have had them very offset making the issue worse.
+youdrpatulot also there are two versions of the pcv depending on local laws. For example the pcv legal in some us states, I believe California is the strict one it only works above 7k rpm making it useless. Make sure you have the regular version that can be mapped at all rpms
good day sir... can you teach me how to adjust the setting of the tps.
I pay for a snatchy throttle. It's consistent and what I expect when riding a litre bike! I could see the benefit if tracking but not for my street use!
outside of the track.... when your girlfriend bangs her helmet into yours because she thinks you're doing intentionally its kinda funny 😂... but when you're in the rain and the rear slips its scary...
can u put a pic of the stock map you used was pre installed
I dont have one handy but its available to download from dynojets site
What is snatchy throttle means?
Ph ph you cannot engage the gas from 0% without the bike bucking like an angry horse.
I have the 2016 no problems at all smooth as can be . I been riding since I was 19 now 52 great bike over all.
+Mark Miller hey that's great. Might be that you got lucky and it really is smooth. Or you might just have a super smooth wrist. Either way. All that matters is that you're comfortable.
Hello Mihai you might be right all that matters is that you enjoy your bike an be safe thanks
Which generation of PCv you used?
M r o hi it’s the PC V
@@hellomihai
Haha sorry:)
PCv means V .
My fault.
M r o hehe all good. Too many names
Got exactly the same problems
Pissed off I have to sink another £800 into the bike to rectify a build issue!
its caused by the emissions requirements and using this really brings the bike back to life. Well worth it.
Didn’t do anything to fix it looks like
yes, the video is a demonstration how the throttle became smooth and more power was achieved
You need to rest the computer
