STOCK ZX14
FLASHED ZX14
BOTH WITH SAME EXHAUST
SAME RIDER
NOW...WHICH ONE IS THE FASTEST AND WILL BE BETTER ON FUEL

I'll take a shot at this one......

Let's answer a Question with a Question(My wife Lives By This One Ugh!)

Ok, two vehicles, First one is a half ton truck. This truck has a v-6 engine

Second truck is exactly the same, only exception has a V-8

The driver is the same in both vehicles. He is a aggressive driver very busy places to go people to see, u know bla bla bla.

With the 6 cyc the driver always had the peddle to the floor to reach the 60 mph speed limit

With the v-8 the gas peddle was to the floor half as long, remaining there for shorter periods of time to reach same limit.

So My question which truck was cheaper to operate ?

Answer the V-8 and the driver was me. Now this of course will not apply to everyone as a blanket statement. So who are you ? If your that guy you already know the answer.

The ZX14 will Not be harder on fuel, should be better. Unless you that guy.... U know, maybe you get on it more and are having more fun. If so the negative should cancel the positive. Mute point

Blanket statement, she will run cooler and father same amount of fuel unless your that guy. Should take longer to heat up in traffic and quicker to cool down once moving again.

If you have any doubts please don't do it. and oh ya buy a v-8 lol thoughts.

FLASHED,,, stop yelling at me lol

Which oil is better for flashed bikes: car oil or motorcycle specific?

Someone send me a stock ECU and I will make passes with it. Fish on?

Hub and Romans, thank you both sincerely for your answers, loved Brock's video. I have purchased several items from Brock over the years and have found him to have a great business to deal with.

I understand digital circutry very well and should have asked my question differently. By the way Hub your write-up was excellent! How does a reflash GAIN hp over a stocker? I can easily see how the reflash changes how and at what rpm the hp occurs but where does the hp increase come in? I have looked at a lot of dyno maps and can see where the curves change but don't see hp increase without a pipe or PCV or some combination thereof.

This is actually my 3rd ZX, the first two all I changed were the pipes, on this one I put pipes, reflash, and PCV. I would NOT want to go back to a stocker even with pipes. I kinda compare my engine to an electric motor with a rheostat, electric smooth and torque everywhere!

One last thing Romans, our definition of smooth. I liken smooth to linear, an example would be my old H2R 750. Below about 7200 rpm you could outrun it with a moped, when it hit 7200 it was like throwing a stick of dynamite in the crankcase. If you were in a corner and let it fall off the pipe and then throttled back up the sudden rush of power would leave a black stripe on the pavement and a brown stripe in your leathers, not exactly smooth! There was a reason the H2R's were called widow-makers and that was one of them.

Thanks again for helping to educate and old man!

1. STOCK ZX14

2. FLASHED ZX14

3. NOW...WHICH ONE IS FASTEST

4. AND...WHICH'LL BE BETTER ON FUEL

5. JUST...WHICH ONE

1. Stock is as you know it.
2. Flash is ever so slight as I/we read it as in a robust bottom end.
3. Stock is fastest because I think I am up on the posted time slips with and w/out flash so:
a. Fastest is the top end and that is stock.
b. Flastest out the gate and then signs off up top is the quickest. Big difference.
4. That I don't know so open a flashing thread as to who has/had the better mileage?
5. ????

By the way Hub your write-up was excellent!

How does a reflash GAIN hp over a stocker?

1. I have a cup [cylinder chamber]. I add a shot glass of gas in the cup. That says stock fuel entering.
2. I changed nothing but the fuel fill via the millisecond staying open longer I change that cell number.
3. I have used more gas, more [heat expanding] to make more HP, i.e, that chemical reaction air to fuel ratio. I want my advance to compensate so I change my cells. No engine or hard parts internally, just more gas and more advance to match more ratio.

4. I have the same compression. I changed nothing on the kinetic as it rises.
5. I remove air cleaner and exhaust system.
6. I caused a less of a restrictive flow and that made work happen sooner I gained hp.

7. I am a head. I have not changed cc's but I did change the flow at the head and watch the evolution.
8. I evolved in port curve is now more of a straight shot down to the valve opening is how I am now.
9. I make hp by less restrictions and that is air flow. Look at how by removing the air restriction of the ac and muff, I caused a faster flow as if the curve is not [slowing air] dragging thru a port with such a C curve; it is now an I port; shot in like a rifle barrel. That is how I make HP over a restricting environment times 3.

A. I did not change cc'snore bore. My head port says flow.
B. I remove the ac element or the sneeze screen, faster is my flow.
C. I made sure I leave no header curve in play or I am back at the [slow] port again at the flow.

D. Who answered my theory'all?
E. Who do I asked when I think flowindski?
F. Who else would know is Pen, the Ultimate.

Signed,
Read it between the lines

Ok My opinion on dis mess...
Ok. Dayum. Im starting understand hud speak! Basically emoticons now the rigamaro. ...
I've posted earlier in this post my dyno charts with changes, with stock config, slipons, pc5 custom map, and with Romans Flash. I Doubt if any one has seen any different changes in hp with modes they have done.

Whoever flash you get is gonna be an improvement over stock!

My findings ... as with my set up. ..and as with most...as far as hp goes the 2012 zx14 with bolt on mods with whatever way you chose to go is max hp with pump gas is 195-200 hp. 115-120 ft lbs trq. Thats it!. As many have said.
I started out with just 2bros slipons 195 hp. Ohhh.. ok so I added pc5 custom map I hit 200hp. Look back in the thread. Got Romans Flash. Same hp without pc5. Basically now with flash you get same tuning you would get with pc5 can now be done in stock ecu. no ned for pc5 in most cases for the average street rider. For those looking for the ultimate setup on there bike, add pc5 with a lil tuning for there specific bike setup with difrent pipes , afr , altitude ect would be recommend if you want the Ultimate setup.
What the flashes do for you is get ride of factory restrictions in 1-4 gears, top speed restrictions, safety mode bike can go into, remove top speed restrictions. ..ect. bla bla bla
Getting ride of restrictions in the 1st 4 gears is where the wow factor is. Which relates to the area where most of use really ride 3k-8k range. 8k on up its all da same...

1.Stock is good.
2.Pv5 and on map better.
3. Ecu flash best bang for the buck
4. Ecu flash pc5 custom map da shit.
Unless you have someone to do dyno custom map strait to ecu. Then no pv5 needed

good write up
so a flash is similar to adding a larger sprocket on the rear wheel for low end (it has a low end fast pick-up)?

(Yes)

Blkcasper your homework here tells the bikes story.

Actually I'm very pleased with the results. Considering the dyno runs were done almost a year apart, hp and trq numbers are almost the same. 2hp less but 2 lbs more trq. What's hard to see in the chart's is that after the flash and the 10 inch stretch, looking at the the graphs the bike is making more power sooner, accelerating harder, and faster. 1st run took 5.161 seconds to peak out. Second run took 5.004 seconds to peak out. That's close to 2/10 of a second faster if im reading the chart's correctly. Riding on the streets I can definitely feel a difference in acceleration when running up through the gears.

Someone send me a stock ECU and I will make passes with it. Fish on?

I would actually love to see that. Back to back runs would be sweet. Nobody at the track will lend you one ?

Which oil is better for flashed bikes: car oil or motorcycle specific?

OMG, just pick the one with no dirt in the tool box lol U funny. I'll take the one with least amount of clutch fibers. My clutch go boom. Lock up time.

It's hard to find another 14R here. It's even harder to find one with an untouched ECU. I might hit my local stealership up and borrow one off a showroom model.

OMG, just pick the one with no dirt in the tool box lol U funny.

That's another drink I owe you!

I have one I can flash back to a stock bin file ... But I want it back when done ..

Well of course Lee. I wouldn't dream of keeping it.

Hub and Romans, Think I finally got this figured out after a lot of reading. Some tuners are remapping the fuel in the ECU and some are using a PCV. Didn't clue in to remapping fuel in the ECU at first, mistakenly thought only restrictions were being removed along with recurve of ignition. Makes a WHOLE LOT more sense to me now. Thanks for being patient and trying to educate when it's my fault for not reading closer!!!

This is a great forum!!!

I have to ask , what are we testing here ? a stock ECU Vs a Flashed ECU ? Who's flashed ECU is going to be used ? I guess I don't under stand what the test would prove because we know a stock ECU is going to be a bit slower ..That much has been proven already ..I think what we want to know is what flash is best ( ET and MPH wise ) So we should be testing Romans/Guhl/Cblast/Brocks/Guhls 2/ flashes ?

So we should be testing Romans/Guhl/Cblast/Brocks/Guhls 2/ flashes ?]

I think I found someone who is using the same brand of eyeballs as me!

Don't forget Ivan. His is more streetable but I want it included.

Isn't that a blind statement? What flashes have you run?

Well I left Ivans out because I already tested it and found it .... Lets just say slower ..Seemed to feel good on the street but didn't do well on the track ..

I believe Hub thinks that the stock ECU is quicker.

sn't that a blind statement? What flashes have you run?

Don't get pissy.

Ivan says that about his own flash.

I want the facts and that means I want his edit measured against the rest.
