The Burger Motorsports JB4 Port Injection Controller attaches to the JB4 allowing it to directly control both traditional port injection kits and WMI port injection kits.

What is the difference between the SplitSecond AIC6 as a stand-alone and the JB4 Port Injection controller?

The AIC6 is a simple stand-alone system that allows mapping of port injection as a function of boost pressure and engine speed.

The JB4 port injection controller is a fully integrated solution allowing enhanced port injection mapping and safety.

For example the JB4 port injection controller:

1) Uses low fuel pressure in conjunction with boost pressure to evaluate injection pressure and adjust PI IPW dynamically as required to maintain consistent flow volume. This becomes particularly important in applications that are at the edge of their low fuel pressure supply. As low pressure drops or oscillates port injection IPW must be dynamically adjusted to avoid run lean conditions.
2) Monitors pedal input, clutch input, gear, throttle position, etc, allowing more advanced mapping and instant cut of PI when letting off the gas or when traction control kicks in to avoid backfires.
3) Monitors AFR in both banks and can cut PI flow in the event a misfire event is detected preventing a potentially lean condition.
4) Monitors current through the injectors and sends a signal back to the JB4 altering it of various problems including a clogged or disconnected injector, blown electrical fuse, loose ground, etc.
5) Monitors fuel trims in each bank and failsafe's in the event of a mismatch of more than 15% indicating a potential boost single cylinder boost leak or injector flow issue.
6) Allows easy user adjustment of overall fuel volume using linear "Fuel Bias 0-100" values by RPM, greatly reducing the typical mapping complications when making manual tuning changes.
7) Integrates into the JB4 multi-map system which produces on-the-fly PI mapping changes when you change maps when boost is reduced in lower gears, or during anti-lag engagement.
8) When equipped with a JB4 integrated flex fuel sensor or JB4 virtual flex fuel sensor can automatically adjust port injection volume based on the E85 mixture allowing for easy mixture changes.
9) Enhanced mapping logic such as tip in supplement to boost port injection during sudden transitions like spool up or gear changes where the high-pressure pump tends to have problems keeping up.
10) Does not require a separate interface and cable for mapping and tuning port injection. It's all done right through the JB4 interface and logs greatly simplifying the process.
11) Includes an extra output to run your second fuel pump OR WMI PUMP (for port injection meth), eliminating the need for an extra Hobbs switch.

This stuff works!
Size: 32 oz
I was sceptical but wanted to avoid replacing 2 rear tires on my zero turn mower. The tires were leaking air and had bad sidewall cracking. I found the use of the product to be easy and quick. I aired up the tires and rode around the yard a few minutes to distribute the product in the tires. It has been 4 days and both tires remain aired up. Previously both tires would already be flat within this timeframe. Excellent results for me!

Doesn’t work for a car Tire seal slow leak
Size: 16 oz
Does not work for a car tire. Had a slow rim seal leak. Out 32oz in still leaks the same. Do not buy. I got the one with fibers in it. It worked just fine. This does not work. Period. $30 wasted actually I purchased two so I wasted $60 when I could’ve bought probably a new tire

#1 Tire Repair
Size: 16 oz
This stuff is Fantastic. I have a riding lawn mower and one of the front tires, which is small, had been running low for a couple of years, we took it off. to fill it with the liquiTube and you could see cracks all around the outside of the tire. The liquid tube oozed out of one of the cracks and sealed , immediately. My brother rolled the tire around real good before we put it back on the track lawn mower. It has been 3 days now and today I mowed for 1 1/2 hrs and the tire as full as it was the day we put in the LiquiTube. This stuff is fantastic, it really, really works!
