Rb25 neo convertion

Post by angelo123 »

Hi Guyz
I am relatively new to the forum. I am busy doing a rb neo convertion. the motor is fitted busy with wiring. I need info on the following.

1. the coils has build in igniters. So can you direct fire it from The Dictator Ecu. By just connecting the coils in pairs with the ignition output to each of them.

2. What will the charge time be for these coils.

I really need detailed info on wiring of the coils.

Thanks

Dicktator will fire your coils directly. VERY IMPORTANT not to trigger them on a FALLING edge, you will burn them out. 2 Ms dwell time is sufficient,.
Your NEO cas is wired opposite to the normal RB25 and is wired the same as the SR20 cas. Use the std. 4.7 V out from the Dicktator to power the cas . It does work with direct 12v as well but is not necessary.

I measured a stock factory NEO and the cas gets 5V.

Coils are wired in wasted spark pairs. Firing order is 153624.
Your pairs are 1 and 6-5 and 2-3 and 4.
