Rev Extend
I know this must have been covered before but can't get the search to work...
Will the Dynojet Ignition Module Rev Extend eliminate the 6th gear rpm limit on 2001 and newer 12s?

I have not heard anything lately but what I know of the rev extender from years ago is it didn't work and in many instances actually lowered the rev limit instead of raising it.
As to the 6th gear limit this is just a guess but I would say that it raises it but does not eliminate it.

Thanks for the reply RidgeRacer. I was hoping it would eliminate the top speed restriction on my A2.

Yes, but the speed restriction is a rpm limiter in 6th gear so wouldn't the Rev Extender raise the 6th gear rpm and therefore the speed restriction? I was told by DJ tech support that the Rev Extend can be more than 500 rpm.

Why don't you just get a Muzzy Bonneville Box?

There are a lot of problems with the idea of using the rev-extend to eliminate your speed limiter. First, you would need to raise the limit around 1000 rpm to get near 205 mph. If your motor isn't built, and you miss a shift or over-rev the stock limit by 1000 rpm...you might have some big problems. Not to mention, 205 mph is not that much...and you have only moved the limiter, not removed it.

Thanks guys. I already have a DJ Ignition Module. I just installed it and was wondering how rev xtend affects the top speed restriction.

it is a try for ridge. i think i remember it is taken off the spedo sensor. so anything you do to the rev limit is not going to effect the mph limit. ridge would have the exact answere.

the rev limit is the mph limit on the 01-03. take that away with a b box or a pc and the mph limit is only gearing and hp. its not speedo related

scott do you get what i am saying? i think the ecu actually takes the pulse from the sensor for the speedo and besides handing it to the speedo it uses it cause the japs know gearing vs tire diameter on their bike so they know how many pps (pulse per second) it is to run 186 and use it to limit speed in 6th. i think it is speed related. just what i remember talking to him about. he would know though. i may have a different bike mixed up like the 14 or so.

well i can tell you a burried the needle with drag gearing before the b box went on. i think the newer ones are speed related tho

will a speedo healer set to a stupid low mph also allow one to go past the mph limit? that would be the test.
weather gearing or speed sensor going to ecu i would think lower gearing with no clutch slip would make it shut down the same unless it thinks it is in 5th maybe.

If the yellow box could fix the problem then we would of all heard about it by now.
Actually I have a theory that I have posted before but is worth repeating.
The original 2000 zx-12 was not restricted. The 2001 I bought was. A quick glance at the shop manual wiring diagrams showed that they had added a wire from the speedo sensor to the ECU on the '01. I put a scope on that wire, found it was a 5V pulse and quickly devised and inexpensive way to inject a false signal into the ECU to make it think it was going less than 186mph (300kMh)
A similar device was soon available from Muzzy. Also the Yellow box came on the scene. While it was originally designed to correct the cluster speedo reading when you changed gear sprockets it also worked to fake out the ECU as to how fast the bike was going.
Kawasaki had to be aware of what was going on and when they upgraded the zx-12r to their new 32bit ECU did something about it. What did they do?
As your letter above mentions the Busa uses the RPM and gear position. You see if you know how fast the crank is spinning and you know all the gear reduction ratios between the crank and the rear wheel you can calculate the rear wheel rpm and from that get mph. The Kawi speed sensor does essentially the same thing only it measures the output shaft rpm and calculates from there. Of course the Busa system is easily defeated by faking the ECU to think it is in 5th.
So maybe the Kawisaki guys decided to go the Busa route knowing their speedo wire restriction had been compromised. But why leave the speedo wire still connected? Besides they must also know that the gear postion restriction is even easier to defeat than speedo one, just rewire the gear wires.
What if they decided to do both?
Restirct the bike if the speedo signal went to high, OR the rpm/gear calc goes to high. People would try the old speedo tricks and they wouldn't work. People would try the Busa 5th gear trick and that wouldn't work.
Has anybody tried the speedo trick and the gear trick at the same time?
It would be no big deal for Kawi to use a 'double restriction' scheme. Its only Software.

This is old but relavent....
Capt10ed did verify the Nikko G-pack
for the 04-05......
I was trying to point out that the 01-03
looks at that 5V pulse ..... Not only
the rpm ...

Healtech's description of the Speedohealer says you can cheat the speed restriction by calibrating way low so the speedo will never indicate 186 mph.
Related question...
Would there be any benifit at all to raising the rpm limit on a stock motor with full pipe and filter?

It will make it easier to bounce a valve shim out of
position.....

i did that in second gear with with the stock rev limit. hitting any rev limit with an air box full of nitrous is a bad idea...

Now that I have an 04 ECU I will be able to find out exactly what they are doing for a speed limiter inside the ECU

Thanks everyone for inputs. Think I'll try 500 rpms and see if it's still pulling.
