I am wondering if anyone has tried this yet by using a usdm obd2 tt ecu ? If it works on obd1 cars I would like to try and make this work to keep my obd2 so I can pass inspection let me know if anyone has any info thanks

 

I'm currently working on that now. Waiting for some connector to come in to make my patch harness.

Nice man i would like to see the progress bc I love the car but it needs to be turboed

 

I got the 2 wiring diagrams last night of both a 96 sc300 and 97 supra ecu pin outs I will be going over them in the next few days to see what will need to be done to run a gte ecu on an obd2 car ill try an keep this updated

 

please do. I have a 97 sc300 5spd that i am slowly piecing together a turbo kit for, and i want to run this setup as well. gotta pass emissions too

 

It can work the wiring is mostly the same except you need to use a odb2 usdm supra ecu, and you can only do it if you are non-vvti odb2. you will need 550cc injectors instead of 440cc used for JDM ecu's and also a TT maf in addition to the parts listed in my thread (or maybe the odb2 2jzge maf might work hasn't been tested yet but its one of those theories floating around).

 

Ya I think the obd2 he maf is the same ill have to see of the values might be a bit different but the look almost the same also ill check part numbers I might just get one as well to make sure I have the right maf for the ecu I know how touchy some can be

 

Yeah usually it has to do with the diameter of the maf when the connectors are the same which I thought someone said they were.
In that case the stock one may be worth a try its already wired up, just do the wiring for the map sensor like shown below, which is a diagram is for a 95 but should be similar. May want to double check a odb2 pinout if you have one.

if you get a good deal on a TT maf you can be sure that one will work though, no need to change the wiring unless the connectors are different, and then you repin the connector don't cut the wires off.

 

Waiting for some connectors to make my patch harness should be here this week. I have all the parts usdm Tt 6 speed and vvti coils. Will let you know how all this goes.

 

Ya I will check on the who map and maf see what I can come up with, I want to get a ft ecu soon but have to sell off my 1jz stuff first

 

good luck guys, keep us posted. I had always limited myself to 92-95 sc's for this very reason, but maybe now I can get a 97 and have it turbo and emissions. thats 2 more years of options, and a whole year with the factory body kit!!

 

Lol Ya I have always limited my self too with sentras and 240sx but now time to try something new

 

Thats the whole reason i wanted a 97 because it already comes with the body kit I want, but it does take more work with emissions and all. I will let you know shortly as I have all the parts now i just need to find the time. Anyone have a throw away ECU. I want the ECU connector to make a jumper harness.

 

No spare ecu's over here, I would probably just get a jumper harness and modify that.
