2jzgte's are direct fire, e.g. 1 coil per cyl
I'm trying to work out WTF why e-manage won't run the timing on the 2jz properly. I've wired it up with one channel to each timing wire on the ECU in the correct firing order...
The only thing I can come up with is that the 2JZGTE's run wasted spark and I've wired it incorrectly...
I've even tried a second unit to see if the unit was defective and got the same problem...

Direct fire can be either waste of normal spark I thought?
They are COP, but appear to have 6 channels out of the ECU feeding the ignitor which has 6 outputs, one per coil.
This doesn't mean they are run in sequential mode necessarily though...
I'm having issues getting my e-manage to run the ignition side of the engine. so the only thing I could come up with was it should be waste spark rather then 6 indivdual wires.
Is your e-manage compatible with the style of signal coming from the 2JZ?? Is it a hall effect, reluctor, optical etc type??
i have seen 2j coils and they plug onto the spark plug and then have a lead to the next plug
so i was under the impression they are waste spark
maybe some are waste some are direct
but if you pull cover of coils and see how many u have
take u 10 mins
2j is reluctor like all j engines
wasted spark can be seen by having the doubleup type coil packs (VN commo, EF Foulcan) where there is one input, 2 outputs... basically look like two coils moulded together.
Hi, BEWARE the 2 wires from the cam angle sensors and crank angle sensors are polarity sensitive at least on 1J's 2JZGTE???????????? crownman.0412 711 481.
on a 2j its not double ended coil
coil sits ontop one plug and then theres a lead from side of coil goin to next plug
I have never seen a 2JZGTE without 6 coils - some Toyota engines (e.g. 1MZ) do run 3 coils on plugs, with a lead going to the other plug, but I certainly haven't seen this on a JZ turbo engine.
im sure ive seen it on a 2j or a 1j vvti
it was def a 6 cyl inline toyota engine
i did a vvti 1j the other day and it had a small ignitor with 3 wires in and 3 out
and im sure i did a vvti 2j with similar ignitor
as i mentioned earlier, it's probably CoP in waste-spark mode (e.g. 2 coil packs fire together). The 1JZGTE is.
Waste-spark doesn't need a dual-tower coil-packs - it just means two cyls which are 360 degrees apart in cam timing fire at the same time.
maybe its cause its an emange heheheheh
never really had much liking for them just a glorified safc
I really didn't get much from all that so far...
Both my 2jz's have 6 COP and a 6 channel ignitor. I'll have to get the CRO out and run a comparision between say IG1 and IG5 in order to see if they are firing togeter etc.
If they are, then in fact the wriing will not be correct as there are indiviudal drivers and ignitor channels for each coil, so they won't be 'hardwire' paired anywhere in the system and hence why the engine will be missing.
I've seen relatively good success with e-manages on 2jz's so am not worried about this side of it. However these have been on Supra's with supras ECU's not the ARISTO ECU I have...
I'll try my spare ignitor this afternoon and maybe even throw the CRO on to compare outputs.
Will keep posted as this seems a bit of an unknown atm.
BTW the e-manage doesn't use pick ups to drive anything, it merely goes inline with the ignitor feed wires from the ECU to add and remove timing, so no interfaces with reluctor/hall etc are required.
Oh and SAFC can't offer 16x16 ,maps nor ignition timing

I've had problems with toyota engines talking to ECU's because of the crappy output signal they put out of their triggers.
I'd be saying that the output from the engine's sensors is not up to scratch for your ECU...
ok guys as far as i know the 2jz ignition is like the 1jz the early non vvti ones are definately COP one coil per cylinder the later vvti ones like te 1jz is wasted spark one coil for two cylinders
CoP doesn't mean they're direct fired ... sideshow and chris found early 1JZGTEs with the coils wired in pairs meaning that they fire in waste-spark mode even tho they've got individual coils.
Okays... Well I'm still uncertain whether the 2jzgte is seq or not, but I've solved the issue. The person/tuning shop i bought this from had a pair of ignition wires in back to front. Now this is easy to do with the Japlish translation showing both pins being yellow black when in fact the ignition in is yellow white and the ignition out is yellow black...
When comapring to an image from a website, the yellow's were around the wrong way... swapped them over and all is good
