tuninghq Posted February 19, 2015 Share Posted February 19, 2015 power commander maps fz07 Before you yank the pcv, you could try downloading their map for your setup. Hey, those maps are for the FZ 09. There do not have a map for FZ 07 with stock air-filter and Yoshimura exhaust. Unless the bike model does not matter...? Thank you Fueling will be different for the FZ-07. The FZ-09 fuel map may make the bike run, but is likely not optimal. The FZ-07 has a different motor design and different displacement. Has anyone ran the FZ-09 map in an FZ-07 PCV? I would be curious to see our SAFR on that bike and see how good of a tune up it is providing.

Premium Member crazycracka501 Posted February 19, 2015 Premium Member Share Posted February 19, 2015 @ugly, It is hard to say what the issue is. Faulty map, bad connections, poor tune. Make sure you have disconnected the stock O2 sensor so it is not fighting your fuel map. If you want to stick with the PCV, I would recommend installing the off the shelf map as a starting point and maybe comparing it to the dyno tuners fuel map. See if there are any significant differences. You showed real class Dillon, your momma would be proud. Make it stop!....Now make it go faster!

Yes, but there's also a fine line to be walked in regards to forum vendors when you're the owner of said forum. I've witnessed first hand what happens when the line gets obscured and it's not pretty (read: vendors getting pissy over preferential treatment and leaving and members getting tired of constant soapboxing and leaving). As a former admin and mod of several other automotive forums, I speak from experience and share this because I don't want to see this place suffer the same fate as others. d('_'d) Link to comment Share on other sites More sharing options...
Cruizin Posted February 19, 2015 Share Posted February 19, 2015 I certainly appreciate your advice and can see that it is good. I do try to spread the love around to all three Vendors and it is easy, because they really are very good at what they do.

ugly Posted February 20, 2015 Author Share Posted February 20, 2015 Wanted to give a quick update. My PCV is currentlyI on the way to Dynojet. I hope they are able to figure out what was causing the issue. Will update once I hear from them. Thank you all for your help. Link to comment Share on other sites More sharing options...
fooschnickens Posted February 20, 2015 Share Posted February 20, 2015 Hopefully it's a faulty unit. The fact that the bike runs perfectly without it points to either that or a botched install/tune. Good thing you can still use your bike while you wait, just sucks that it won't be with hat extra power the PC should have given you. :/ Link to comment Share on other sites More sharing options...
scordiaboy515 Posted February 21, 2015 Share Posted February 21, 2015 Awesome! Remember to leave a review after you have it dialed in! Did you also rent the Fueling gauge? Will do. I do have a wideband ive used for tuning my cars, might see if i can rig that up to the bike. Otherwise i may just buy one of the dobeck safr fueling gauges, between me and my friends with bikes im sure it would get used enough the way it was explained to me from the owner of Max Speed Cycle is the o2 sensor is removed when using a PCV, seems that the ecm is trying to read with the o2 sensor and not letting the PC do it's thing.

That would be a stock narrowband O2 sensor. They help the bike maintain a certain emissions legal AFR during light load cruising and low rpm. The Wideband O2 Grahamfz07 is referring to does not connect to the ECU and just provides an air/fuel ratio readout so you can see how the bike is running and then make adjustments to the fuel controller until it is dialed in.

ugly Posted March 11, 2015 Author Share Posted March 11, 2015 Hey people, I have a quick update on my PCV issue. Dynojet still has the unit, but let me know what the issue was. Here is part of the email from Dynojet: [span] During the process of testing the unit returned to us ,we have discovered what the problem with your unit was. There is an accelerator pump feature in the configuration settings that has been configured incorrectly and is causing the surging and bogging down. The accelerator pump feature is designed to be engaged when you make a substantial throttle change such as coming out of a corner when you have to let off the throttle and then twist it back on. This feature is activation is user defined based on their preferences of how they like their throttle response. Normally we recommend at least a 20% throttle change to activate it, but your unit was set up to activate it at only a 5% change, so any little modulation of the throttle would activate it and deliver extra fuel, so for all intents and purposes it was engaged almost all the time. When this feature adds extra fuel in the lower rpm and throttle settings that are normally controlled by the closed loop system and our provided O2 optimizer, they ;then try to remove that extra fuel to retain their fixed settings and this would cause the bike to surge and hesitate as the system is fighting itself by adding and subtracting fuel all the time, rather than having a smooth constant setting. If you want to use the accelerator pump feature it needs to be set so that it only activates upon a substantial throttle change of at least over 20%. This feature was designed more for track ridden race bikes where throttle lag coming out of corners may mean the difference between winning the race or not, but has little or no use on a street bike, and would be best turned off on bikes with closed loop systems. Race bikes eliminate the closed loop systems so this feature works well with those bikes. Street bikes with closed loop systems will always have some surging in the closed loop area if this feature is used with them. If you need any more information or have any questions please let us know. So it seems the unit itself is just fine. Anyone with a PCV on their FZ 07 turn the 'accelerator pump feature' off? Do you have it on? At what % does it activate? I will be getting in touch with my dealership and let them know. I am so glad that it wasn't a serious problem, and eagerly looking forward to getting it back and put on the bike! Will update as soon as that happens. Thank you guys![/span] Link to comment Share on other sites More sharing options...

fooschnickens Posted March 11, 2015 Share Posted March 11, 2015 That seems like something that should have been caught on the dyno, but I'm glad they were able to find the issue. Link to comment Share on other sites More sharing options...
adamb Posted March 11, 2015 Share Posted March 11, 2015 I suggest having someone different tune your bike. If that slipped passed them who knows what else they could do, maybe a lean melt down. Link to comment Share on other sites More sharing options...
fooschnickens Posted March 11, 2015 Share Posted March 11, 2015 I suggest having someone different tune your bike. If that slipped passed them who knows what else they could do, maybe a lean melt down. I agree. It wasn't caught on the first tune or when you brought it back to have them inspect it. Luckily it just dumped fuel all over itself which is relatively harmless in the short term. I'm not as well-versed in bike ECUs as I am in car ECUs, but if there's one thing I do know is that glossing over or messing with features like he described above can cause serious damage. Luckily this one just dumped a whole bunch of fuel and then had a mental breakdown while it tried to sort itself out, but it could have been a lot worse.

ugly Posted March 15, 2015 Author Share Posted March 15, 2015 Ok, time for another small update. Once I heard from Dynojet, I passed the info onto the dealership service department. Here is their reply: I apologize for not responding sooner. Regarding the email you received from Dynojet - Jody and I both read the email and discussed it; and at this time we agree your bike runs great without the power commander on it and we believe the stumbling you were expriencing was caused by a lean condition, not an overfueling condition like Dynojet believes it to be. We are able to fine tune the power commander settings with the assistance of Dynojet, but we are hesistant to due so since we have found your bike runs so well without a power commander on it. Ultimately the decision is yours, however we do feel that in your specific application, a power commander is not needed. Let me know if you have any further question, or feel free to stop by the shop and we can discuss it in more detail. I would like to get the PCV reinstalled with the PROPER config. If I do not do that, I am out $700 for nothing! That makes me MAD!!!! I absolutely hate this back and forth, not my fault but theirs crap! Once I get the PCV back, I will take it back to the dealership and have them get in touch with Dynojet and get it right. I would not have gotten the PCV if they had not HIGHLY recommended it! Well, what do you guys think? Link to comment Share on other sites More sharing options...
Guest whitegas Posted March 15, 2015 Share Posted March 15, 2015 You've just compounded my opinion on never ever dealing with a dealer again after initially taking the bike home. Sorry you still have to deal with all this bull**** brother. Did you have to pay for the installation? If so, they need to make it right. Link to comment Share on other sites More sharing options...
fooschnickens Posted March 15, 2015 Share Posted March 15, 2015 Did you have to pay for the installation? If so, they need to make it right.This. If their product and/or service hasn't made you happy then I would push hard for 1) a full refund or 2) making it right at no additional cost to you.

ugly Posted March 25, 2015 Author Share Posted March 25, 2015 Ok, time for an update. I got the dealership to reinstall the PCV at no extra cost this morning (3/24). The bike still has some of that stutter. It's not as bad as before, but there is still a problem. I think I am done with my dealership people. Just going to suck it up go to EDR here in Beaverton. I was told they specialize in bike tuning, etc. I like how the bike performs with the PCV. It feels smoother, and more responsive...when it works, that is. What can I do? Should I try a map for a different exhaust with stock air filter off of Dynojet's website? Put in random numbers on my own? :-/ Link to comment Share on other sites More sharing options...
Global Moderator mjh937 Posted March 25, 2015 Global Moderator Share Posted March 25, 2015 If I was you I would head to the specialist and never let that dealer touch my bike again. It seems like someone who knows what they are doing should be able to get your tune right. Personally I would avoid just monkeying with the numbers. You could possibly do some damage. Keep us updated. Link to comment Share on other sites More sharing options...

I am already feeling the separation anxiety! Will update once that is done. Thank you all! Link to comment Share on other sites More sharing options...
