2jzge distributor link atom setup

[David]

Been trying to get my friends 2jzge hilux going has a link atom

ive wired trig 1 to NE Trig 2 to G1 and both grounds to G-

is this correct?, has spark to distributor cap but nothing to plugs

first time use of a link ecu all other sensors are working as awell as injectors

You should be ok with the way you wired the dist. 

Could you post a copy of  your cal file?

And if you have spark to the cap but not the plugs, I would be looking at a cap and rotor or the whole dizzy itself.

is cal file tune file? will post that when i get home, that dude who wired it up had a werid setup and coil and this black box got real hot but had good spark... didnt seem very safe, do i need single channel ignitor to coil then to dizzy? is there a way 2 test trig outputs without a oliscope

cheers david

do i need single channel ignitor to coil then to dizzy?

Yes you definitely need an ignitor, can you confirm you have one?

is there a way 2 test trig outputs without a oliscope

There is a trigger scope built-in in PClink.  If you have spark at the coil though that would suggest the ecu is seeing at least some of the trigger.  Another quick check is to watch RPM in PClink when cranking, if it reads around 150-200RPM during cranking the trigger is probably ok.

The fact that you have spark going into the distributor and nothing coming out would suggest you have a rotor phasing problem. (i.e spark going into the distributor when the rotor is not pointing at a post)  Provided the engine has run before and the distributor hasnt been moved then it is probably the trigger offset that is wrong rather than the distributor position.  You could try adding increments of something like 20degs to the trigger offset until you get a spark coming out of a plug lead, once you have a spark coming out of a plug lead you can then put a timing light on it and set the trigger offset properly.

im gonna say no  Igntion 1 >Black box> coil > dizzy is how i first seen seen, got rid of the box seemed dangerous was gettin hot, 2jzge distributor parts dont seem to easy to find here, been thinking about goin 2 wasted spark.

Adamw, I'm sure you just overlooked it, but OP has this going on with an Atom.  They don't have the on board trigger scope function.

David, could you post a picture of this black box?  It sounds like an ignitor to me.  If it is an ignitor, it will generate some heat.  They usually have a Heat sink side and that does need to be mounted to a flat surface for it to transfer heat and not damage itself.

must be gets way to hot for my liking, my mate who owns the truck is pretty keen to convert to wasted spark as dizzy parts are expensive and rare here.. could i use a rb igniter with vn coils or best 2 get a properly 3 channel igniter

[Brad Burnett]

yes you can convert to waste spark with no issues. 

The Rb ignitor is typically a 6 channel ignitor. 

What coils are you going with?

[David]

v6 3.8 vn commadore ones, yea was wonderding if i could run 1 ign channel through 2 as there gna join on the otherside anyways? any factory igniter soultion only 3 channel ive found is like 200$

[Brad Burnett]

If those coils are individual per cylinder, you can run the 6 cylinder ignitor and just have each of the 3 ignition channels split to 2 channels on the ignitor.

if the coils are double ended coils(each coil has 2 plug wires coming off) then you can still use the 6 cylinder ignitor, you will just only use 3 of the channels instead of all 6.

[Adamw]

I dont think VN coils will work - I'm pretty sure they are the old GM "DIS" system?  They bolt on to a special base that has all the DIS electronics inside.  

[David]

http://m.ebay.com.au/itm/201608772548 is the style of coils im talking about have been used heaps for rb wasted spark setups

[Adamw]

Yes, notice they dont have any direct input connections on them?  The input terminals come up from the base plate underneath that they bolt to.  I dont know how they would use them on an RB - maybe there is some aftermarket base plate you can get for them without the electronics in it?

A brief search suggests you can actually modify the OEM DIS base plate to bypass the internal electronics but it looks like a pretty crude modification to me: https://www.diyautotune.com/support/tech/customer/gm-dis/
