Introduction

I'm building a 1997 Hyundai Tiburon and trying to build it as fast street car.

So far the parts list is as follows:

ems- Vems 3.3 :)

turbo-garrett gt2876R

wg-Tial 38mm

greddy BOV

injectors- 780cc lowz

wiseco 83mm pistons

pauter rods

arp head studs

I have hooked the vems to a 12v supply to start getting more familiar with it. All the sensors work but ive got a first problem with VR sensor but looks like people have had it already.

It seems like the signal is very low beacuse rpm gauge shows no movement as i connect the sensor(tried to change the polarity)

If the signal was erratic I would need some resistors to clean it but in my case what should be done?

megatune configuration is-rising edge, multitooth(60-2), no filtering

TRY2

I tried to generate a waveform and input it into vems as rpm signal but with no luck so far...

anyone know what ise the minimum voltage(mV) where vems will start getting the signal. LM1815 starts from 0,4mV already i think?
