And I am COP, do I following correct ?
TT ecu or standalone
Vvti coils and ignitor Dh61 (or use camry ignitor ds62) + wiring
Exhaust cam needs to be for a 2jzge.
Cps is optional, it saves space over distributor even without plugs as you can see in my pics. Does take some extra work to put the cps in.
Just finished modding the valve cover plastics for the ignitor wires.
got a lot of pm's for more details on going coil on plug so here is one of my responses.
you need the coilpacks, I recommend the IS300 coilpacks for na-t.
you need a toyota 3 channel ignitor to match (you can use the is300 one DH-61 which is really expensive or you can use a camry ignitor DS-62 which can be had for $30) they are the exact same, have the same plugs everything, completely interchangeable. I have been using the camry one for over a month now boosting very happy.
and then you just run the extra 2 wires from the aem to the new ignitor for T2 and T3 (remember you only had 1 coil before now you have 3), you can leave the original T1 and IGF in place no need to run new wires.
Next you depin all the wires from the old ignitor and plug them into the new ignitor's connector, like T1, IGF, +12v and tach (technically IGF is not used by the aem but I plug it in anyways). the only wire you dont need from the old ignitor is the one going to the old coil, you leave that unplugged.
The old ignitor doesnt have a ground wire but the new one does, add a wire and run it to battery ground, pretty simple.
so now you have everything but the 3 coil wires from the ignitor to the coilpacks, cause we are not using the old coil wire cause it goes to the wrong place. so you need to make a harness of 4 wires that run to the coilpacks, 1 trigger for each and a +12v that runs to each one (all 3 coils spliced into 1 12v wire).
It should look very similar to the following: http://store.driftmotion.com/static/...torharness.php
In fact I would just buy this and extend it, then you will have a new harness with new clips.
I made mine from scratch because i didn't think toyota sold this part.
If you have a Aem V1 skip to settings you need to change in aem v1.
If you have a AEM V2 they changed the way you turn on and off the coils.
They have coils 1-6 and for each number there are A and B coils.
In the supra TT file, notice there are values for 1-6 but nothing for the B's because TT uses sequential ignition.
with the vvti setup it uses waste spark so we have 3 coils that fire twice, so instead of thinking of it as 1-6, the AEM V2 thinks of it as 1-3A and 1-3B.
so you need to turn off coils 4-6, but we will borrow their values and move them to the right spots.
Since 1 and 6 are paired cylinders, we turn off 6 and turn on 1B and put the values for 6 into the 1B box.
repeat for 2 and 5, you would turn off 5 and turn on 2b and move the number over again.
repeat for 3 and 4, turn off 4 and turn on 3b and move the number over again.
I dont have the software in front of me right now so all of this is off memory, be sure to take a look at the n/a cal file and the TT cal file and you should see what I talking about with the "A" and "B" coils.[/B]
SETTINGS YOU NEED TO CHANGE IN AEM V1
Go to: Ignition > Advanced Ignition > Ignition Phasing > options.
change the settings in the ignition phasing for coil 1 in the aem to the correct settings 21.53
The 1101 base cal the setting for coil 1 is 22 which can blow your motor when you do this mod if you don't change it.
You will need to sync your ignition timing
it will throw it off about 14 degrees.
Go to: Options > Coil
To turn on the extra coils check Activate for coils 2, 3 and 6-8
once you are running coilpacks, you can swap out the distributor for the 7M CPS to clean up the bay. both the dizzy and the CPS will get the job done but the CPS sensors work better with the AEM cause you can turn the cam/crank to high sensitivity (with the distributor it may stall if you do this).
Go to: Setup > sensors > cam/crank > advanced cam/crank > advanced pickups
You can leave spark teeth at 24 if you turned on coils 2, 3 and 6-8 (recommended).
to change to the 7M cps you need to change the sensitivity on the cam and crank high below and low above settings all to 6000 rpms, exactly like it is in the 1130 cal file (for a 7m-gte). If you are using the stock distributor, leave the stock settings alone.
