Split Second Controller - 4 Injectors
Here at Damond Motorsports we carry and offer Split Second Controllers to allow you to add 4 additional fuel injectors to your Mazdaspeed or Ford Focus ST/RS.
Whether you're adding our Mazdaspeed PI adapter plate, or converting to an ST intake manifold with our PI adapter, we've got your fueling covered!
The AIC1-V4H w/4-channel tach is a highly specialized version of the AIC1. It is specifically used to add four additional port injectors on 4-cylinder, direct injected engines. As with the other versions of the AIC1, it is programmed with the R4 engine management software which is included. Connection to a laptop is made through a USB to serial adapter cable which is not included. The USB to serial cable we sell on this site is highly recommended.
Instead of an internal pressure sensor, the AIC1-V4H w/4-channel tach has a voltage input with a 0-5 V range. The voltage input can come from a stock or external map sensor, or from an MAF sensor. This means the load can be based on either pressure or flow and is not limited to a fixed range.
The AIC1-V4H w/4-channel tach has four separate tach wires. A true-tach reading for engine RPM is generated by the four tach inputs. Each tach wire is connected to the trigger signal on each ignition coil. These tach inputs work with coils that are triggered by narrow 5 V pulses. Modern Ford and Mazda and other direct-injected turbo engines use this type of coil trigger.
This unit can be ordered with either EV1 or EV6 injector connectors. This unit does not come pre-programmed. It is essential that you load an appropriate map before running this unit on an engine.
Legal only for racing vehicles which may never be used upon a highway.
Works great and easy install. Ordered 4 injectors controller even I only have a 6th port injection and worked perfectly. Will take advantage of it once I go 8th port injection. Indeed r4 is old system but quick and easy map swap. Didn't bother me at all.
It doesn’t even show correctly on a laptop this is so old technology. If they at least updated the software it might be better. I consider it junk compared to what you can buy now at 450/500 even. Spend a few more bucks and get something that wasn’t made in the 80s from the looks of the included software.
Bought this to control my Port Injection setup ( 4 injectors ) on my 2010 speed 3. Simply love it. Easy to install and learn. Comes with a good amount of length to the cables so u can mount it in a nice spot. Only thing needed that is not provided is a RS232 TO USB Cable to load the fuel maps to the Split Second Controller. Program is little older but easy to navigate. A++++
Always Excellent Customer Service
