just a fair warning, people have been having heat soak issues with all of the new power with these systems. may want to upgrade cooling after using these!
@@WhiteDiamondTL - yep it has a few maps from factory. It's best to do logs and test with them. Jump on google and type JB4Tech Forums and they will run you through the process.
I think it’s an awesome addition to the GR Corolla. Having just that little bit extra boost is very nice. That being said I have only kept it in map 1 but you can instantly feel the difference. I highly recommend. If install is your biggest worry it’s 100 times easier than I thought it would be. Let me know if you have any other questions.
I’ve got my Corolla coming next week and got my test for manuals this Monday coming 😂 love that
I would wait the bcm module to appear - it improves the boost management alot. Can of course be installed also afterwards
Nice circuit! Im jelly cause of the color but i didnt hsve the option in the core i opted for. Great video.

@@richie.grainger okay… cuz I was looking through the firmware update and only found one for the grc/yaris
@@richie.grainger which boost settings have you used? I’m scared to move it past 3.5 😂
Is the jb4 already tuned for stock gr ? It are there pre set tunes that you choose from?
So this was on a stock GRC? No intake, down pipe etc?
Yep
I want to buy this but no one has given a review...what do u think about it... Since you've had it for a while?????
Its good but requires setup.
Hey man, I'll get my nephew Josh to come give you his feedback on it. Last I spoke to him, he was loving the JB4 on the GR Corolla.

@@joshuasteckiw8155 thank you for taking the time to answer...🙏
I would recommend, it takes about 30 minutes for install if you understand wiring. It does make the difference. Best bang for your buck
How it's acceleration now??
Should do 4.5 seconds easy
