1JZ VVTi Individual Coil Upgrade STOCK ECU!!

Показать описание

G'day everyone!

Glenn's Supra with its 1JZ VVTi had developed a missfire under load. In this video we quickly explain what we did to test why and show you how we went about an upgrade that can be done on a budget and works with the FACTORY ECU!

Once again, please leave us a comment and let us know how we did!

If it's beyond your skill level, please don't try this at home! If you would like some more details on how we did it, leave us a comment. Follow anything we have done at your own risk. We have filmed this all in our after hours time. Remember to always use/wear correct personal protective equipment and be safe at all times!

Thanks for the video👍 about to do this swap very soon and was wondering how you deleted the oem wasted spark wiring harness?

Interested in a write up on the wiring if possible? Great work btw!

So it would still be firing 2 coils at the same time I assume as thats what the ignitor outputs?

friggin amazing information A1 !!!! Subscribed, friend!!!! Love your work and the videos!!! keep em' coming!

I am going to try this, I just did the 2JZGE to 2JZGTE ECU Mod and it runs good but the vvti coils I got are just breaking up at 4000rpm and up. I am going to try this on the 2jzGTE ECU and vvti Igniter since the igniter is similar....

so in theory, it would work for the 2jzge with the 2JZGTE ECU mod (aka NA to TT ECU mod by AliSC3). I don't want to go standalone as I want OEM drivability and emissions in California 🤦🏽‍♂️🤦🏽‍♂️🤦🏽‍♂️and thank you for the fuel pump video as well, brothers!! CHeers!!!!

P/S: don't you need to just jump the R109 resistor for the tacho to work for the Supra, same as a 2jzge to 2JZGTE conversion, init? just wondering, correct me if I'm wrong.

sick video i just did the haltech ps2000, it's a cheap ecu and supports this out of the bat

Where can we get a new tach signal for the car if we need it for other accessories?

Hi, I also have a 1jz mk4 supra that's experiencing the same issues. Thinking of doing this conversion too, however I have an ECUmaster ecu. Would it be more or less the same process?

How's this setup still working? Any issues? Did you upgrade to an aftermarket ECU?

Very cool 🤙🏾. maybe you should sell a tidy little jumper harness for igniter and 370z coil harness kit I’d imagine lots of folks would be interested
