PC V and Autotune box

[busacaptain]

Anyone install one on the 08 yet?

[ResidentEvil]

I've had the PCV on my 08 since last year and I've been waiting on somebody else to try the Autotune first...but they need to dyno the bike before the autotune and again after with it installed and report back.

Maybe I should call T-Pain and ask him about the Auto tune

[busacaptain]

The Dynojet website doesn't list the 08, I called and they said they have not tested it yet but should work. They said to call Fuel Motto, I called them and was told it works with no issues so I ordered it.. Don't know of any Dyno's in the area to do tests on but I will find out..

[ResidentEvil]

You are correct,08 its NOT listed but it works its all the same ...DYNO JET asked me if I had any problems with the PCV ...None and I did get mine from fuel Moto and they will have it loaded with a map 4 u

I am running the PC V with auto tune with a Yoshi R-55, so far I like it. I got mine from Fuel Moto with a preloaded map and according the my laptop, my baby is running around 13.2 to 13.6 AFR. I want to put it on a dyno, see some numbers, and found out how she is running. I know fuel milage is down but she runs great with no hesitation.

Just my .02 here, take it how you want but.......Forget about PCV, Bazzaz(Piggy Back Rip off Units)! "ECU Editor" is the ONLY way to Fly!

Many products (including ECU editor) allow you to change the fuel map, but you should never change a fuel map unless you know what to change. Downloading a map from a website or from a friend is only a starting point. All maps can benifit from fine tuning. I see many people at the track making changes to these map, but they don't have a datalogger to give them the required information to make an effective change. They almost always end up going slower. The autotune is a very cost effective alternative to a datalogger, and for most people is a very quick and efficient way to tune.

I recently helped set up a friend of mine with a PCV and autotune. He had struggled for 2 seasons with an innovate datalogger. The Innovate is very difficult to use; power interups, sensor overheating, signal noise issues are all very common. He finally gave up and installed an Autotune, and got a perfect tune in one weekend. Unless you have a strong understanding of electronics and can work through issues with loggers, I would recomend the Autotune for the average guy to get the most out of any map setup. (Toxic - I think its pretty safe to say your not the average rider)

ECU editor is a great product as well, but it doesn't provide datalogging or fine tune your map like an autotune. It allows much more control over engine parameters including timing and rpm rev limits. Great product (thanks Petrik) but different use and user.

I will find out tomorrow how easy it is and hope for the best.......

For those running the Auto Tune, don't leave the sensor in all the time. Use it only when tuning and taking short samples. Leaving it in full time will burn out the O2 sensor pretty quick.

Can i use auto tune to run a dry nos system???

Really,, that sucks.. How can the stock O2 sensor stay in without burning up?..



I have been reading about Auto Tuners for the past two days and I am going to get one (the bazzaz set up).. Was gonna post the exact same question about them on here but glad there is already a thread about it.

I have been using one on a Kaw. I did the base tuning by hand on the dyno first because honestly its a big trust to assume its going to work right all the time. Once you get a sold base tune in, shorten the correction window down really tight within 5% so the auto tune can only make small changes. I suggest working with one throttle position area at a time from 5% on up. The unit I am using appears to be dead on with our Dynojet 250i's sniffer. Placement of the o2 sensor harness may cause that to vary. Also be sure to have the connector side of the o2 in a well vented area, fresh air stream if possible.

The auto tune uses a math program for correction. Its as close as this in MOST cases. Say you have selected to have a 13.0 AFR. Your base map currently has 12% or a 12 in the fuel cell area you want to take fuel from. The Auto tune will subtract -10% or a -10, which should change that 12.0 to 13.0. This works the same with free hand tuning. If you are reading data on your wideband on a specific throttle position and RPM or while on your dyno and you see a lean spike of 13.8, add 8% of fuel it should bring that spike down to 13.0. Its a constant math process throughout the rev range and throttle position. Now if you see a lean spike of 14.7 and you want a 13.0 add 17% it should get you right in the neighborhood and a 15.7 whould amount to 27% so you get the math.

Play with the above info. I am sure it will shorten your tuning time down pretty fast. Keep in mind this varies slightly from RACE fuel to pump gas but it works. When you get good at running the math in your head tuning is super simple...remember tune away power dips not just to a set AFR.

Great info Greg! Thank you for the detailed description. You have no idea how bad I want to get my bike up to your shop. And to think before moving to Raleigh I was 45mins from you

Thanks let me clear this up...I made a small error...


The auto tune uses a math program for correction. Its as close as this in MOST cases. Say you have selected to have a 13.0 AFR and the Autotune sees that the AFR in the set rev and TPS range is 14.0. Your base map currently has 10% or a 10 in the fuel cell area you want to add fuel to. The Auto tune will add 10% or a 10, which should change that leaner 14.0 to a richer 13.0.

Sorry I was typing faster than my thoughts. You get the point. Drop by when you can....we will be here.

Only one day and all I can say is better hold on when you twist it.. Yes, milage takes a dump from 43 to 29, but I didn't buy it to save gas... I need to play with the tuning on it now, but the system was very easy to install and download a map to it.

I do like how you don't have to have the key on or bike running nor the 9V battery anymore.

I got the Auto tune for my 09 Busa and the sensor doesn't fit in the exhaust. Is there and adapter or do I have to make another hole in the exhaust for the auto tune sensor to fit?? I got the PCV with the switch and the yosh R-55 full exhaust

You need to make another hole for another 02 bung..

[apeluv]

Can you tell me how??? I wanna get this on the first try and not have to buy a new exhaust... Help???
