Megasquirt to VR6 Distributor or Coilpack wiring.

[PiercedWinky 0]

Just thought I would pass some information along and add to it abit.

 

need_a_VR6 on vortex has gotten a few of these running. I myself am about to setup one for a friend and also one for myself. (if anyone local to me wants one built or help with wiring LMK)

 

Here are the details for wiring directly into an old ECU connector or just hacking apart the wiring at the end of an ECU on a VR6

Here is the circuit info:

MS1 V3

MSnS-E 029t

 

Board mods/hardware:

 

VRIN - TSEL

 

TSEL - VROUT INV

 

D14 with pullup to IGN (no VB)

 

Both VR pots fully CCW

 

Launch Circuit

 

Tach Circuit Works with 4.7k pullup

 

TIP120 for PWM idle valve with 1N4001 flyback diode between output and 12v

 

Remove Q4, Q20 and R39. replace R39 with a wired link or solder the (E) emittor to the right side of position R39 rather than at the Q4 position.

 

Innovate LC1 wideband to stock narrowband O2 pigtail.

 

Tach circuit uses a 4.7k pullup to 12v, the ignition mod uses a 1k pullup to 5v.

-------------------------

 

Currently I am still looking for information on how to use the stock coilpack without removing the ICM. I should have that figured out shortly. You can use a wasted spark setup with 3 VB921 or BIP drivers. Just wire directly to the coils instead of the ICM.
