Neither, I use AEM EMS4. Wiring was a nightmare, but it's been solid. I use it to control both PI and my secondary LPFP (Stage 3+). It uses a 5bar AEM MAP sensor for boost reference and also references a few other sensors via ECU splice. To my knowledge, JB4 is incapable of controlling a secondary LPFP. There are others using Haltech to do the same thing.
AEM gives me batch firing in pairs (1-6,3-4,2-5 if I recall) and a much better tuning platform than the craptastic AIC6 interface. I've gone out of my way to avoid using jb4 and I'm happy with that decision.
To my knowledge, AEM/Haltech provide safety mechanisms that jb4/aic6 cannot.
I think both are rudimentary. Using the AIC but not at all confident in it to be honest.
"It works" accurately describes where we are with PI right now.
I've never heard of this option.. Is this cheaper in comparison to Haltech?

Sparknotes: DI please...
The thought of the AIC and Hobbs switch irk me big time. They work, but there's nothing beyond that.
Not exactly. They have a pulley to overdrive the pump, but not really a replacement where the pump can move more fuel on it's own. I'm still considering that setup. My only concern is whether or not injectors will be up to the task for long (think daily driver) periods of time.Somebody already has its VTT
Still haven't bought either controller. Leaning towards the JB4 BMS PI controller.. apparently one of the issues with the regular AIC6 is that it can continue to spray when the DI side stops dumping fuel (only for a millisecond) but the BMS controller allegedly stops that from happening which can avoid engine damage or backfires, etc. Just hearsay - I've never ran either but I will be pulling the trigger on one of the two in the very near future. One drawback is that you can't pull logs or make changes from the BMS controller where you can with the AIC6. It seems like there is no 100% "safe" PI controller, but out of all the sub-par options, the BMS controller seems that it could be the safest/most user friendly. I'm in for opinions and feedback also.
