Icic, i Should be good then at my 8# until i move up. Might get one just to be safe?

I'm at 10.5# with my zl1 pump and ADM module. I don't have any fuel pressure drop even when I have a boost spike to 11+. They do both increase fuel pressure when under boost, the BAP does it by increasing voltage and the ADM module just does it like in the factory boosted cars, by PWM.

Have no fuel pressure drop with added boost either with, both zl1 and adm.

Someone explain why you need a different fpcm when a BAP can get you extra flow with a ZL1 pump.

Lingenfelter does it with just ZL1 pump and BAP.

Don't think anyone said you need the FPCM if you have a BAP. As I said above, they are different means to the same end, without getting into opinions about which is the better route. I went with the FPCM because of ease of installation. I felt that I preferred to just swap the FPCMs instead of splicing a BAP into my wiring and running a boost reference line.

I was not necessarily talking about you or even this particular thread. But I've read in other areas that you have to get the controler and tune it.

I"m going to tune it before anything and keep an eye but just want clarity on exactly what is or is not possible.

I also know a few that did the straight swap with no different tune.

I'm pretty sure if you don't change the tune, it will not ramp the pump up like it is supposed to. Basically, they swapped it for no reason.

adm module? I didn't see it is that the same as the kenne bell boosta pump?

Ok I get that. But my point was you should be able to swap it and drive the car, just not expect the fuel pressure to be any different?

Reason I ask is I want to be able to drive the car to the tuners if needs be.

No. The KB BAP is what I have on mine. The module is different. Not sure in what way but it is.

Yup, you can drive the car after the swap. I just don't think it will be able to ramp up without the tune changing.

Cool. Ya, I just would like to be able to ease it to the tuners. Comporession is a little lower and cam is a bit bigger so I might not be able to anyway. Plus my injectors I can swap out when I get to the tuners.

I can trailer it if I have to but would rather not have to. lol

There is nothing to change in the tune unless you change the module also. Running just the ZL1 pump, you just drop it in and go.

Seems so simple but there is a bit to think about.

Let me set it straight. Correct me if I'm wrong on any of these.

All of these are ZL1 swapping into an SS fuel pump.

ZL1 pump swap with no tune. Pump will run same as stock pump. No more flow/pressure?

ZL1 pump swap with tune? More flow/pressure?

ZL1 pump swap with a BAP and no tune? What will the BAP do at this point?

ZL1 pump with tune and BAP? Should be about 50% more flow.

ZL1 swap with FPCM swap and tune? Obviously the best but is it more flow than the BAP?

Obviously all are WOT full run.

I wish I knew what exactly the FPCM was benefiting. If Lingenfelter uses a KB BAP with it then it must be pretty decent.

NO, not at 800 crank power but surely 700?

What does this mean?

Feel free to tell me to piss off. I know I can be hard headed.

Zl1 pump in stock SS: modest increase in flow. Not pressure.
Zl1 pump with module and no tune: same as above.
Zl1 pump without module and tune or no tune: same as above.
Zl1 pump with module and tune: the ADM module allows PWM modulation of the pump to increase flow and pressure as demand increases, as in the factory application.
ZL1 pump with BAP: the BAP increases VOLTAGE with a boost reference internal to the BAP.

Damn. Quick response. I appreciate it.

Well I guess I may do a module but first try and see if the BAP keeps up.

ZL1 pump is already in and BAP is already there so I should have some good flow once tuned. If not I"ll do the ADM module. There is another one out there too that my builder told me about.

JMS Powermax fuel pump booster.
