keep in mind i had this car running flawlessly on a usdm 93 2jzge ecu maf setup. I THINK I MAY HAVE TOASTED MY TT ECU. so i went back to stock 330's to elimnate messing up fuel wiring. ill upgrade those the day it idles on all 6. I grabbed a spare ge dizzy vvti ignitor and coils. bassically the first time i wired it up i had the car running with the mk3 440s and resister pack from what i think is from an accord. bough the setup from a kid i think he was standalone though but he ran them. along the wiring i had broke the plug at the distributor. i def wired that up wrong and the car ran for about 1 minute and then still crappy on 3 then just shut off and it wont run on 3 ever since then. it cranks and backfires and starts about 1 to 3 seconds. im thinking i fried my computer. i got the ecu to show the cel light but its just blinking and wont flash any codes. dont worry i wired my ecu to have power at the ecu so it saves codes. i really think i fried this thing.

another thing i noticed is that the 2jzge ecu pinout has the 4 wires going straight to the dizzy. theres n1 g1 g2 and G. where do i wire G on the 2jzgte aristo pinout. there is no G on the aristo pinout. im also curious. why is there another stack of n1 g1 g2? G was wired up the the other n1 if that makes any sense. so another words how are you guys wiring up your crank sensors? or do u just leave it like i originally thought


i swapped the n1 g1 g2 to -n1 -g1 -g2 and im getting nothing. just cranks

Iím using the distributor as the crank position sensor. No change in wiring needed. Just removed the cap and replaced it with a 3D printed cap.

I meant that my car is currently running using this mod and the distributor. I did not change any of the distributor wires.
So did you move your distributor wires back to their original positions?

Also, blinking CEL means that there are no codes.

Ok guys I am extremely sorry if this sounds dumb...I have a 93 JDM supra that runs on MAP and IAT from factory can I just plug up the TT ecu, 440's and TT map sensor? Its never that simple but in essence over coffee, it should work shouldn't it?

Does it have a coil on plug system or distributor cap and wires. If the latter, you will either need to modify the igniter setup to run the distributor or rip the wires and cap out in favor of coil packs and wire up a new igniter.

Thank you for the quick reply. The JDM NA's are on distributor and wires with a 1bar MAP and IAT.I would be more inclined to blend the systems and get the TT ecu to run the stand distributor and wires...versus converting to cop I cant do a whole lot with it where I am now so I'm just trying to get it to run a smoothly as possible till I can ship it. The main concerns were the harness and pin out for the NA vs. TT and since the two main differences being the MAF and the MAP wiring wasn't necessary if anyone had some info to lend. I'm having a super hard time finding out about the non-us market MAP based NA's not much is out there from what I'm searching.

There is info on running the wires and cap: https://www.clublexus.com/forums/sc-...ml#post8524788

The post shows that he has the Coil on Plug setup, but he hadn’t installed them yet, and he got it all going without it. The information is on pages 113, and he has a few videos of his setup on page 114.

to upgrade from the jdm 2jzge ecu to the tt ecu is basically the same thing except you can skip the step of wiring the map and IAT. instead just swap your n/a map sensor for the tt map sensor and that step is done.

you still require 440cc injectors and changing the ignitor. to use the stock distributor get the ds62 ignitor and follow the instructions on page 1 to install without going coilpacks. after the ignitor change you still need to do the tach cluster mod to get the rpm gauge working.
