Thanks Ali that was perfect!

 

stupid question but i havent strated the wiring just out of curiosity the connector diagram up showing the number on the connector is that wen im looking at the connector or behind the connector or looking at the ecu

 

The diagram is looking directly at the ECU pins, or the backs side (wire side) of the connector which is facing the same way towards the pins at the ECU.

 

this site has a nice diagram of the pinout and is the JDM version, so you can also consult here

im building my harness for the ds62 to my is300 vvti coils. i just wanna clarify the pin out for the two wire on hte coil pack.. which oneeire goes to which pin on hte coil pack connector ive read around the diagram i might have missed it but i cant find to see which pin is which on the coil pack i see the two line ur drew to the coil pack jsut dont know which line goes to what pin

 

has anyone on here is running a AEM F/I C 6 controller with the tt ecu mod

 

Copy the stock coilpack wires. yes they sit in a certain way and I dont remember will check later on maybe snap a picture.

Not that I have heard but alot of people use them in the vvti's especially the IS300. ecu is totally different but it should work on the ecu's we are using just fine. probably more complex to setup though than some.

 

Random question I forgot to ask in the past that I never saw come up.

After doing the coil conversion is it necessary to maintain that small grey square box under the stock coil?

 

so printed out the wiring of an is300 it is showing a (b-w)wire goin to pin one which im lookin at the pin one wire is tcoming from b+ from igniter and they all share
which is that orange line u made to the cols on ur diagram
then the the second pin goes to c2 c3 c1

 

Yes, leave that in, its wired seperately from the stock coil and you need it its called the EFI noise filter. all toyota's have it including the 2jzgte. on the supra 2jzgte its on the ignitor bracket on the drivers side. ours is on the passenger side by coil but its fine to leave it there I left mine there.
Do not remove it or your ignition will act funny.

looks like pin one is the power wire and pin 2 is the trigger from ignitor. 'i wonder if the connector says which one is pin 1 or 2.

 

I have a small issue.

Idles ok, drives fine, but at WOT she bogs big time(kind of feels like fuel cut). AFR shows it gets really rich but she pulls fine in 2nd, 3rd... with no bogging.

Is the ecu expecting boost and that's why it bogs and gets rich at WOT?

Would going COP/distributor less help?

(95 SC 5 speed, aristo ecu, 440cc Osidetiger injec., no turbo yet)

 

its expecting transition to boost so it gets richer but that alone shouldn't cause bogging.
what it is likely is that your injectors are slightly larger flow than the factory ones, which causes it to be just rich enough to bog especially without the turbo pushing the extra air. either add the turbo or add a fuel controller and take away a little fuel. even with the turbo sometimes you have to remove a touch of fuel depending on exact injector used.

 

Exactly the response I wanted. It's time to order the full turbo kit. Driftmotion ftw.

 

turbo is always a good idea =)

going coils would help spark with a rich mixture as you can run larger plug gaps, also running Iridium plugs will help not foul out as easy with a rich mixture. The BKR7EIX is what I use along with the vvti coilpacks.

you can get the job done with the stock distributor, but if you can get past the wiring bit coil packs are much better in the longrun.
likely its more of an injector / no turbo issue right now.

 

Awesome!
I just ordered those as well. I want to change my plugs soon just to see what they look like.

On my car, when changing the plugs other then removing the intake pipe, everything is the same as stock right? If I let a general shop do it, there is nothing different they need to know right? My gap should be stock right?

Thanks!
