RPM controlled switching- Launch/NOs/Mivec?sub injector/etc

[E-Tech]

Hi all DIYers@zth

4-5 months ago, i did some searching and finally found a guide to make this.
(Buying a Bee-R launch was out of budget.....)
My purpose was to make a DIY Launch Controller ... however since the rpm signal is adjustable,
you can trigger a 12v relay for any purpose...from cutting ignition, fuel, on sub injector, on mivec, on horn, on central locking system and etc at what ever rpm you want.

example....
Set rpm adjustment to 6000rpm, once reach 8000= horn sound...or
5500= mivec trigger... or
4000= ignition/fuel cut... or
4000= sub injector on....etc

Final product pictures...tonite upload...

Haiyo... when read already and think it was good effort pls "thanks" lah...

E-tech Launch Controller... basic function yes!

Press button switch (switch or hook up to handbrake switch, or make clutch sw)
Note: if clutch switch,,,best cos can also full throttle shift..
In gear 1 which clutch full depress...
Full throttle- rpm cut where you set, tak ngam adjust...ba ba ba ba ba ba ba

Relase clucth to launch the car...
When tires have good grip, release launch button...

As i also said, can be use for many other functions...anything you want to control by RPM.
Can also use e.g as rev limitter- e.g your hot girl friend drive your fairlady.. you set 4000 rpm cut,
then she cannot more than 4000 rpm loh... TQ

I studies also the concept used by MSD- cutting of ignition for rev limitter/launch control..

[E-Tech]

selling it in future? :D

I do have 1 or 2 laying around...
Do let me know what you intent to use if for...
In addition, you would basically need a std automotive 12V relay..
TQ

interesting
how much it cost to do this ?

since i looking for rpm activated controller as well

but a question
this is activate it at certain rpm
but will it deactivate if it below the selected rpm ?

like mivec controller, at 5000rpm activated
but when it rpm drop back to 4800rpm.. do it deactivated or still activated ?

 

[ek_elleh]

i remembered that beeR hav 3 dial, right??
but yours only have 1 dial..

is there any different/lack in function??

btw, you are doing great!!

interesting
how much it cost to do this ?... material cost RM60-70

since i looking for rpm activated controller as well

but a question
this is activate it at certain rpm... and onwards (up wards)
but will it deactivate if it below the selected rpm ? (yes... below set point, no activate)

like mivec controller, at 5000rpm activated Yes, but on 5000 & >, off at <5000
but when it rpm drop back to 4800rpm.. do it deactivated or still activated ?

Bro, clear?

 

[jombiee]

, you are good ! how about quote us price includes installation bro.

E Tech
got it clearly
but how you determine the RPM signal ?
since there is no display to show the rpm
it is using RPM switch ?

i looking for 2 unit.. willing to make and resell it for me ?

i not E&E people.. but i looking for this kind of controller
