Rev counter
 

I have the same problem, i connect the GP style anolog on to my orange wire on the ECU, but it seens to under read by 1500 -2000 rpm?

2004 to 06 XT's have twin spark ignitions, ignition sparks every 360 degrees of crank shaft rotation.

2007 to 2010 XT's have single spark ignitions, only sparks every 720 degrees of crankshaft rotation.

So to answer your question you need to change the input reading on your rev counter to get the correct RPM range. It should read around 1400 rpm at idle.

Great Kev !!!!!! I didn't know this. You are ever the better !!!!!!!!

Ciao.

Think the problem is mine only has 3 settings , 4 , 6 ,8, cylinder seetings??

Hi,

if we are speaking of the same rev (Micro RPM GPT),

I'm copying by manual :

there are present two buttons, one with ARROW UP and another one with ARROW DOWN, for easiness will call them P1 as ARROW UP and P2 AS ARROW DOWN.

Set up :

Press P1 for 4 sec, after will appear SET UP, then release P1
Pushing P1 you'll scroll the parameters
Pushing P2 you change the parameters. The features are the following :

t (strokes) 2 or 4 (default 2)

p (pistons) from 1 to 8

H (max rpm) from 1.000 to 25.000 (default 7.000).

Is the same rev counter type ???

Hello guys, thanks for the response.
I have already performed some calibrations on stokes and pistons configuration settings (I am talking about micro rpm).
I get the correct rpm on idle 1400. If for example I use more pistons, I get 700 rpm on idle or 400.
I have activated in parallel the secret menu to compare with the default XT rpm meter.
By doing the above comparison I have noticed that the problem starts from 3000 rpm, where the micro rpm meter starts to over-count.
I have also checked in the manual that if you have problems you should try to make a small coil with the rpm cable around the spark.
That didn't work for me.
Do you think that if I cut the cable it will improve the behavior?

Fit a 10K ohm resistor inline between the orange coil wire & rev counter.

You can also try connecting the the rev counter wire at the ECU not at the coil.

Otherwise cut the cable (50 mm. per time and repeat the test).

Bye.

Thanks a lot!!!
I will try the above and come again with the results!!! :toothy12:

p.s Kev, in order to fit the resistor, if i understood well, I have to cut the wire.... am I correct?

No, you have to unsolder the cable, put the resistor betwen circuit and cable and resolder. Bye.
