Haloo -

Well, up to now have been enjoying my 2006 ZX immensely. Mods besides the swingarm extension, is limited to removed flies, Boz Brothers 18 inch straight slip-ons, BMC filter (which according to whom you ask, does do much on the ZX14 anyways), and the Schnitz-flashed ECU... well, just picked up a good used PC V with the intent, of course to find a bit more power and feel safe using the dry-shot nitrous.

So these questions are 2 part so here it goes...

1. The Schnitz-flashed ECU already has "Gear Based Fuel Trims Removed from Gears 1-3"... the map on the used PCV has one that has a map for the flies removed as well... so if you know what I am asking, if the ECU flash already increases the fuel maps in the 1st 3 gears, should I have a map that further increases fuel with flies removed? I do not want fuel added by the PC, added on fuel map increases from the ECU flash... As for the BOZ slip-ons they are pretty much straight pipes already (and loud as heck), but should I use a map with any slip on from the list on the PC website?

2. For the 2nd map I intend to add a switch to the PCV to switch to a nitrous map, one I have in the used PCV already has a simple + 40% fuel add... problem is, did not get much information on my nitrous nozzles, but I figure 30-40 shot. Short of taking it to a dyno, is there any single-stage nitrous maps kicking around I can load that are conservative-safe for these nozzles?

Question 1 is straightforward... question 2 not so much but any pointing in the direction is useful.

PS please do not "point" me in the direction of the recent (and nasty) posts on whose ECU flash is better... just need some sound advice particularly on the PCV map-over a Schnitz map with the flies removed.

Thanks!

Never had a flash yet but the only way you are going to be perfectly safe with NOS and have optimum fueling is if you tune the flash with a PCV. I doubt the extra fuel from a flies out map will amount to much compared to a NOS map.. Bare in mind, you won't be using NOS at all in 1st gear.

I doubt the slipons are going to make a huge change in flo even if they are loud. I believe you have all cats removed with slipons on the 06 but the header is still stock. I guess with everything you have going on, flies out, slipons, and definitely NOS, I'd plan on going through the whole AFR tuning regimen. If it weren't for the NOS, I think you'd be safe enough without any extra fuel but missing out on a few hp.

I figure 30-40 shot. Short of taking it to a dyno, is there any single-stage nitrous maps kicking around I can load that are conservative-safe for these nozzles?

I'm not an expert but 15 shot nozzles are more what I would consider conservative. Based on what I presently know, I would not run a 30 shot without having my mapping pretty close to perfect. Go to the dyno or get autotune and start with a small shot working up to a larger shot as you tune. I'm just starting to laarn this process myself.

My opinion, you don't need a flash at all on a Gen1. It will save you a lot of time but in the end, the traditional electronics will do exactly the same thing and you will be able to tune EXACTLY as you wish for your bike. If you do get a flash, you will be doing this anyway. 0 need for youi to have a flash on your 06 and if you're running nitrous DON'T TRUST ANY TUNER THAT TELLS YOU TO GET A FLASH FOR A NATURALLY ASPIRATED BIKE.

Plan on getting an Ignition Module instead of a flash. What you need is timing tuned if you are running NOS.

It's a lot of fuss. Autotune or shell out for the dyno.

My bike is naturally aspirated and my tuner told me that for anyone who takes their bike to the strip that is advantageous to get the Guhl flash because it prevents the bike from going into the safety mode and it gives better mid-range performance and bumps up the rev-limiter 500 rpms and takes off the top-speed limiter. I ran a guy at the strip with a gen 1 14 with a PCV and a 30 shot and he took me by a bike or two in the 1/8 mile. He did not have a flash, just had his bike tuned for the NOS via the PCV. I am thinking about getting the Guhl flash.

The Schnitz flash on Gen 1 ECU raises rpm by 500, opens the flies sooner (not a big deal as my flies are already removed)... and removes the fuel trim in 1st 3 gears due to the flies out... there is no safety on Gen 1 that is only a Gen 2 thing... And, I already have the Schnitz flash, so I will not be doing another.

I figure PCV is the best way to do fuel maps, not via flash... I am not looking to take every single 1/100 of a second off my 1/4 mile times, and I will not be re-flashing my already flashed ECU... heavens, again I have read the ridiculous posts on who has the best D**K (best flash) yada yada... the Schnitz is simple and works as advertised, no more no less - I have driven a stock Gen 1 ZX14 pretty castrated on the low end vs mine with flies out and Schnitz flash; it works on the lower end as advertised to increase the power by removing fuel trim with the flies out. It advertises this and it does it... good enough for me.

As for exhaust, the Gen 1 header is already not bad with no Cats to begin with, and I doubt an aftermarket header does not do much more than the stock header for flow. However, a slip-on vs stock pipes, there is definitely better flow. That is why I am simply going to choose a map that accounts for slip on, like Muzzy, should be close enough to the BOZ.

The question again, is, do I pick a map that adds for fly removal, on top of my Schnitz flash which already does this. Simply wondering if the maps available for the PC V should I pick one that adds fuel for due to fly removal already, on top of the Schnitz flash that does this, or pick a map that does not map for fly removal and simply adds more fuel all round. I do not want it to be overly rich on the low end, flash-on-map...

As for NOS, yes again I get that and mine is pretty conservative and I am not looking to take off every 1/100 second on the 1/4 mile, just want to use it safely every once in a while. I will likely take a line off the solenoid to hook into my PCV switch, the instant I hit NOS it also switches the map. And that is what I am wondering, I read some guys start with +15 on the NOS map and tune from there. My map is set for +40, which seems a bit high, but I guess running too rich is not a bad thing.

Just to clarify, i was speaking about any person who wants to rune NOS should avoid AFR and probably timing for a naturally aspirated bike. If you are running NA, by all means, get a flash for NA. You will still probably get a little benefit from fine tuning. IDK how much benefit. Probably not very significant if you are running the bike at the same elevation as the map was made at. This Gen1 you raced is doing it the right way. He has tuned for NOS. He could have a flash with NA AFRs used as a base map but he would have to tune for all the extra oxygen going in with NOS.

there is no safety on Gen 1 that is only a Gen 2 thing

If you hit 186 mph, your bike will go into limp mode. Low power until you shut down and turn back on. I think that's what skewed was talking about. All bikes have it. Bonneville box or Speedohealer or grindig the countershaft nut will bypass the top speed limiter or apparently it can be flashed away.

I doubt an aftermarket header does not do much more than the stock header for flow. However, a slip-on vs stock pipes, there is definitely better flow.

I always thought the same but I don't question what is used for racing. Racers use full systems and usually brocks Muzzy or akrapovich. There are dyno results available and slipons on a Gen1 might only gain 7-8 hp where a good full system gains 15-18. The full system is also lighter. The stock header weighs much more than race head pipes. After all is said and done, the full system is not horrendously more expensive than quality slipons.

The question again, is, do I pick a map that adds for fly removal, on top of my Schnitz flash which already does this.

The PCV will add and subtract fuel from whatever map is in the ECU. If the flash already richened up your flies closed range, the PCV flies out map will richen it up even more. You will run rich if you use both together. Might become a flame thrower. If you already had the flash I'd go with that and use the PCV to tune for NOS. You're not going to get it right throwing in NOS maps that were made for a stock ECU. You can run a NOS map all the time. Fuel does not get added for NOS until 6000 rpm. You could also use the map switch to select between a NOS map and a NA map. Any way you cut it, you will need to tune.

or pick a map that does not map for fly removal and simply adds more fuel all round.

An NA map is going to subtract a lot of fuel on the top end. If you use this map in your PCV, it will be subtracting from whatever map is stored in your ECU. The PCV map will also add in some places. remember, the PCV does not overide the ECU mapping, it simply changes it.

Tuning is a very exact science. You don't want to go throwing maps in the PCV to change values that have already been changed via flash unless you know the PCV map was made with the same flash you have.

Think of it this way, the PCV is a tool used to adjust what is in your ECU to suit your specific needs. Whatever has been flashed is now what is in your ECU. If your going to use NOS, you are going to have to tune--- unless you can find a NOS map that was made with a Schnitz flash and the same size shot you are using.

The Schnitz flash on Gen 1 ECU raises rpm by 500

NIce. Fun. I would like it for kicks but the Gen1 peak hp is about 10,500. You won't go faster revving higher. Nice buffer for avoiding the rev limiter. You don't want to hit that with NOS. If you're serious, you need an electronic failsafe if you hit the limiter by accident...or miss a shift. If you're just using NOS for fun and plan to be extremely careful with it, you will probably be ok but if if you're racing, you need all the electronics which will put you somewhere close to the cost of a used turbo. I like NOS. I plan to use it in the street but things happen in the blink of an eye racing. If something happens wrong, BOOM.

Thanks Rook that is useful - think I will pick a Muzzy slip on map that does not tune for fly removal as well, due to the Schnitz ECU flash already taking care of that. I agree the tuned headers would give a bit more jam, though the 1st gen headers are pretty straight through, that may be next year's mod... love the Boz dual short exhausts though they sound wicked.

"If you hit 186 mph, your bike will go into limp mode" the Schnitz flash also removes the top end limiter, so it will carry on above 300 kliks, though I have no need to go that fast! I have gotten 2 "get out of jail free" cards from 2 very nice officers, one at 150 KM/h, so I do not want to push my luck further!

The raise to 11,500 is good, I have my tach light set to flash at 10,500 so by the time I see it and shift I am at about 11,000 and the extra buffer keeps it safe.

got a get of jail free card last fall doing 90. just cruising along. few years ago got nailer for 110. He let me go but i got the ticket. Court appearance with lawyer did no good. 6 points, 15 day lic suspension. Fortunately i blend into an urban environment at that time because i had to drive to school. I'd never get away with that here.
