port injection

Hello all i am in need of some insight on my split second controller. Currently i am running a 6th port set up and will be switching over to 4 port here in the future. My current controller on came with two ID pig tails and am wondering if i can Y in two more injectors to the current two on the...

Hey folks, I guess I'll start this thread and see where it goes. I bought a 2012 MS3 brand new back in 2012. A few weeks later I took it up to a dyno day at Modern Automotive where I met many great people. My car made 272whp bone stock with less than 300 miles on it. The next week I swapped...

I recently acquired a built MS6 with PI. The split second controller will not connect to the ECU. I have tried 2 different USB to Serial cables as well as verifying power and ground connections are good. The MAF is putting out .68 volts according to the AP. When I turn the key to on and plug...

The OEM fuel system with e30 is good to about 370whp or so before you start to see some wild IDC "injector duty cycle" To fix this people will run port injection on top of the direct injection system. This provides fuel when you need it the most "higher boost" and supplements the OEM system...

After playing the mixing game for too long I decided I would like to try out a fuel cell and just run straight corn in it. I looked at a lot of options and moving the battery or doing a trunk cell but with small kids in the car I did not want fuel in the cabin. So here we go. This is as budget...

The stock mazda fuel wire appears to be 14-12awg it might be less but it is hard to tell. I was having some strange lean issues and this seemed to help. I re-wired the pump with a dedicated 10awg wire and a relay. The hellcat pump can def pull more amps than the stock stuff is rated for. I am...

I finished my port injection setup and I have noticed a strange issue. I thought I was alone in this but it appears that @andale927 and @Bigelow have similar issues. The issue I have noticed is that the FPR is pulsing, it will pulse + or - 3psi at idle. This pulse can be both heard and felt in...

The Split Second Controller is use to control additional Port Injection injectors. It uses MAF voltage and RPM to know how much to spray when. The controller is programmed via com to usb cable. It's kinda old school tech but it works well and is much more reliable then meth. I will not be...

I thought I would share my port injection setup for all who are interested. It's not the prettiest, or the most amazing thing in the world, but it works very well and can be the cheapest option of full PI if you know where to find used parts and you're good at substitutions. This is a full...
