Cobb FMIC Follow Up


Cobb FMIC Part 2 Update:
With nearly 11 days of real world testing on the streets of California, we're back to bring you some data. The last few days here in California has been well over 100F. Perfect for this kind of testing and although i tried to stay out of it much as i could, i had to get out there and see how the car reacted to the temps with the Cobb front mount installed. i was also able to capture some data in much lower temps as well as evening temps.
Prior to the install of Cobb FMIC, i had changed the setup of the car. Originally, an ETS 3.5" was installed on the car. I also had a manual boost controller set at 18psi and a map clamp. To conduct these tests, i chose to install the stock TMIC along with removal of the MBC and Clamp. I wanted to see how the car reacted to stock boost with the new FMIC as well as give an ideal scenario for the average owner who may not have these type of mods. Also, we wanted to collect some data from the TMIC and compare it to the Cobb FMIC.
Testing Methodology:
Although crude, we just don't have the extremely expensive test equipment like the big boys have. So, we must make due with what we have at our disposal. In the makings of this second half, I made arrangements to order better equipment for future tests, so at this time, we are using our trusty MSD Dashhawk loaded with V2.5 Beta 4 with all of the Mazda updated PIDs.
It should be noted that Cobb has helped MSD with their software in achieving better accuracy from the stock sensors. The unit itself is nice, gives you digital readings of sensors of your choosing, able to log 5 parameters during data logging and allows you to store up to 5 separate data logs at a time before downloading. It has several sample rates of 1250,2500,5000 and 10,000. Again, although crude, it works for this test to compare the stock TMIC to the Cobb FMIC since data was captured from both using the unit.
We chose Mazda specific PIDs during the test. They were Wideband AFR, Engine Coolant Temp, Boost Temp, Intake Aircharge Temp and Boost/Vacuum.
