u can run any kit you want but only the hfs4 is integrated to create a failsafe with cobb. it also works using injector signal and boost. so run your bms kit but if your map is very aggressive and it fails to spray you can hurt stuff.

You need to buy a JB4 to control the BMS meth kit. You can either sell the Cobb or use it for BMS's backend flash. If you can still get around $600 for an AP in the used market, I would unload it and buy an OpenFlash tablet for $395 if you decide to do a backend flash later on.

The spray and pray approach is not advisable. Meth kits fail all the time. The last thing you want to do is blow a cylinder and destroy your engine running too much ignition advance under load

As I stated above, if you want to run a Cobb flash only - then you will need the aquamist.
Otherwise, get a JB4 with the FSB on top of the BMS flash. You can't run a BMS flash on its own anyway. |

now with that, the easiest way for you is to get a boost switch and set it to something like 7 or 8 psi. you won't even have to connect to the DME and you're all set. of course you have no failsafe with that method.

FSB is really limited in failsafe ability. Speaking to some locals running it they always have issues with the thing burning out and having to replace it. It also just guesses on actual flow unlike Aquamist that sees real liquid flow. Once the kit is spraying there is little difference but the advantages are everywhere else and they are critical to engine health and safety.

I second the HFS-4 it's a great kit with a lot of features and honestly your only option if you want to run a meth kit with intregrated failsafe and flash only. Snow has something called safejection, but I have no experience with it.
