Default 2.5 Turbo efficiency - 06-20-2022, 10:37 AM

Installed the JB4 on my CX-50, everything works flawlessly.

I have a couple questions on this platforms turbo if anyone can give me more infor to tune my map6. On my Q50 TT, there was information available on the max PSI and also turbo efficiency at certain RPM/PSI. I couldn't find any of that info for the Mazda engine.

Currently my Ign1 is still at 5 at 5k RPM, so I think I'll have some room to increased boost at those rpm.

Thank you in advance.

Terry will the CX-5 still get boost oscillation if bit 7 is disabled?

Installed the corksport boost tube and noticed a little boost surging. Looked at my settings and linear pedal bit 7 was disabled.

Didn’t think the boost tube would really change that much, but wondering if I should do an ECU reset or if it will just adapt over the next few days?

Also for fueling I’ve been adding 2-3 gal of e85 to target approx e28 when I can. But have been topping off with PNW92 when I can’t get e85, so my fuel is going from e28 down to PNW92. Is that going to mess with my trims and should I just stick with PNW92 with no e85 if I can’t get e85 consistently?

Hi,
Today I noticed I hit 26.3 psi max boost briefly on map 2.
Is that safe with the stock setup? I also happen to be running 30% E85, only other mod I have installed is the borla axle back.

Could be normal, just depends on the details/log and what the factory boost target was at that moment.

Since we've added MAF control revisions in v4 the pedal mapping has not been needed to smooth them out at part throttle. But you can always email me a log if you're having an issue and I'll review.

The tuning is very sensitive to MAF flow and intake design we've found.

Hi, is the v5 firmware suitable for mazda 6? I updated to v5, i dont think maf temp works on ign6 channel since it shows 10.9, for IAT_temp it shows higher temps than trans temp with about 35F difference, (IAT_Temp was 150F while Trans temp was 115F). Shouldn't post intercooler temp be lower than pre intercooler? Btw ambient temp is 108F, at night.

There is no pre intercooler temp for the Mazda 6. Remember how the jb4 is different for the 6 than the 3. So ign 6 is MAF but needs to be multiplied by 10. It is scaled that way because it expects a timing value. The trans temp is post intercooler and the iat is the manifold. Follow your map connections

The values on the 6 may be different, post up a log and lets check it out.

Default Water methanol Injection - 06-24-2022, 08:23 AM

Enjoying the minor benefits of water methanol injection being controlled by the JB4 on my 2021 Mazda CX-5 Turbo

-Lower intake manifold temperatures
-Constant fuel trims
-Lower ign 2 values

The IAT is the intake manifold and the Transmission Temp is the post intercooler temperature.

There are no tuning changes in it, only logging changes. Anyone is welcome to try it. We're hoping TEMP_IAT (intake temperature) is correctly mapped to charge air temperature post intercooler now with the change.

Default CEL with Mazda CX-30 - 07-07-2022, 07:36 AM

Hi guys I ve just recently installed the jb4 on my cx-30 but I'm getting a cel
I'm updated to firmware 4 through the PC software.
I've installed correctly and if I switch everything back to stock cel goes away obviously.
I am running a BMS stage 2 CAI, a borla axleback and resonator delete if any of that info helps at all.
I am getting a code while engine on
061BC6 no description found.
I've double checked and triple checked all connections and everything is solid

Sounds like a MAF fault code so place the MAF connection to factory and clear codes to confirm. Then email me install photos and we can start technical support. terry@burgertuning.com

Removed BETA designation from the Mazda JB4 tuners as the v4 mapping has been really solid.

Yeah there have been some delays in getting hard parts out due to labor shortages. I know that team is working as fast as they can to get caught up on production.

There are around 80 pending intake orders, and we have a batch of 250 due in a couple of weeks. So we'll find caught up soon enough!
