Pure 800s with jb4 a91 locked ecu

[GTSDON]

Hello all so I got unlucky with the Ecu lock, and even tried getting an early 21 ecu coded to my car, which didn’t work, now I want to know if installing pure 800s and running a jb4 with meth would it be possible to run it without issues? Besides the CEL and stuff, I know theres a sensor that doesn’t get used on the pure 800s there for it won’t read boost, or whatever.. How would I got around it, the ECU Locked with a jb4.

Thank you

On stock flash with Pure800 you will most likely run into torque limit codes and go into limp mode

Full flash is highly advisable

PCV heater core is the sensor that gets canceled, besides throwing a code it won't do any harm.. Tuner coded mine out

JB4 has Pure MHD BEF. I am looking into same thing until i get mine unlocked and ecutek

Thank you for that! So how do we go around it? Shouldn’t you theoretically be able to make it work somehow? Not to its full potential of-course but to somewhat better than stock! Also the jb4 does not read boost Due to the Pcv heater core, without a tune

how are you planning on flashing it if your Ecu is locked like mine?

I was right on the date bubble. Bought the jb4 when I thought I was screwed.
Tuner confirmed mine can be unlocked recently.
Just haven’t made the switch. Will probably wait until upgrade the turbo

If you end up selling your jb4 id be interested.

ECU still has to go through bench unlock to work with the BEF, right?

I’m trying to figure out how MHD could flash the ecu if it’s locked

You were not wrong, you didn’t know it’s different!

Did either of you / anyone else start running a pure 800 on jb4. I’d like more info on this limp mode speculation. Plus just to know how smooth it is will be very helpful for me at this time

There is at least one who posted a time slip. I am awaiting mine. @Jesse DaBears ,comments on above? Please say there are no codes.
