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...

I look forward to the PWM control. I have attached a log on V5 with my CX-5. Thank you for adding the additional temperatures. I'm interested to dive into the logs more when I have time.

For the MAF, the ECU expects to be able to control the load with the throttle %. If the throttle % isn't lowering the load fast enough, it will cut the boost target. It doesn't ignore the boost...

Does anyone have information on the following?

1.) How to calculate the actual load since the logged load is the manipulated value?

2.) When PWM for WMI will be available?

3.) When can the...

You should have the "V2" harness for the cx-30

V1 with MAF

Thank you! The MAF addition to V1 is no joke. I am regularly seeing 25+lbs of boost in higher gears after a few weeks of driving.

Is this true for V1 and V2? Would make sense why manual MAF scaling isn't changing anything on the V1 with MAF application.

Map 2 will be fine with default user settings. The WMI for safety is based on me changing settings around and occasionally testing things with map 6.

Don't run map 6 unless you understand that it is going to try and attain +5psi and don't put a "1" for meth trigger mode. This is "default".

Given that the turbo inlet pipe of the Mazda 3 turbo looks nothing like the CX-5 2.5T, I would say no.

As far as I can tell from the sites pictures, the turbo inlet is different for the CX-5. The corksport CX intake will fit on your 21 cx-5 but does not replace the turbo inlet.
