Hypertech anyone?

I want those BATs. Are you spraying water/meth? I don't get any KR at WOT on my current protune until the BATs start getting high, like 130+. Then I can get 1.0-2.0 sometimes. Hoping to solve that with WMI next summer.

You're logging the wrong AFR (at least in the second one). What you need to log is a mazda specific PID, iirc.

and I doubt he's running meth, when I was, in this ambient temps, I would see 40 degree BATS



edit...just saw in another thread he's running meth...what were the ambient temps then? I would consistently see below ambient with my setup.

Both AFRs were the wrong one. I changed it in my new logs. AFR at WOT is 11.5 at 3000 rpms tapering to 9.8 at 6000 rpms. I am running a small meth nozzle. I had a 225 ml/min but can't find it. It still drops BATs 20-30 degrees. I do not have one of the intercooler bumper scoops in so its only getting maybe half the airflow as normal which at this ambient temp is not a big deal. FMIC goes on friday, and ill get a new 225 ml/min nozzle.

That and a FMIC will fix it. That second log is the only knock I have seen on boost in the last few weeks.

I found out that the hypertech tune hits boost/fuel cut at 19.5-19 psi.

you need to start logging fuel rail pressure...you might be getting fuel cut too, and if thats the case you have a very good chance of fvckin something up soon

I was logging direct injection fuel pressure for a while but it was always a solid +1600 psi even up to 6000 rpms. I guess it wouldnt hurt to make a run logging it again. I guess my question is how do you determine the difference between boost cut and a fuel cut? Doent the ecu cut off all fuel when the boost reaches the limit? Also wouldnt there be a huge hit of knock if the pressure dropped?

Edit----

Here is a log showing fuel pressure. Had some .4 knock.
