Fuel pump voltage boosters

The answer that people don't generally use BAPs on these cars is because the high side runs out at around the same power level no matter if you boost the low side to feed it. If anybody is really going to make more power they have to do something with the high side as well and at that point you may as well do another pump on the low side to get some real headroom vs a BAP. It wasn't like this on the Gen4s since there is no high side to worry about and deal with which is why they are much more prevalent on those vehicles. And the trolls, I mean "team" has tried to claim that a BAP is the new answer to not throwing a low pressure code which it isn't. We routinely have cars running up to 175+ mph in the half mile which puts them right around 150-200 more rwhp than stock and they don't throw this code and no they haven't been disabled either.

Thanks for the follow up. I misunderstood what you were saying in your first reply when you said "adjust pulse width based off of the injector pressure vs manifold pressure on the high side not low side" I thought you were referencing pulse width of the low side pump, not of the injectors. Everything else said is more or less my understanding of the system as well
Still can't find any trims in GDS2. Any memory of where you access them?

Right, but when you do an aftermarket tune, you disable COT in some instances, and in all instances, you change the tune not to run rich as GM's factory tune instructs the car when it sees extra power making oxygen coming in.
To run rich, requires more fuel to be flowed. What NicD and a few others are still ignoring is that we can cause ANY factory tune c7z to run out of fuel on a cold day, while at sea level, and throw codes p228c and p0089.
He can argue against the reality all that he wants, but we know that we are right, and GM knows we are right, as GM is going through the lemon law process on the first of 4 cars, as we speak. The hearing is set for 30 days from today. We will let you know the outcome soon.
But, back to our focus, these volt boosters have the potential to fix the factory tune z06's from ever running out of fuel in the cold/sea level situations.

Imagine what a great place this forum would be if people with your knowledge and skill walked into a thread and pointed out what you do agree with from each and every party who has spoken thus far, instead of point out everyone's flaws and call us all names as you always do.

If you guys need to increase the low side fuel pressure on a LT1 when supercharge, you can use the fuel pump control module from a 15+ Z06 they are the same as LT1s but with different program for more fuel

Ahh yes and that's exactly what this whole thing was about to bring it right back to where you guys started on this forum and what you are still pushing. You really think that preventing it from running rich is really worth another 150-200 horsepower worth of fueling? Really? Really?

We are speaking about z06's already. We already have the z06 low side pumps and modules.

so, I guess this is your chance to say you either realize he was correct and you were wrong (meaning, there is a problem with the cars that he discovered), or if you would like to stick to your original argument that his car had a problem and GM can fix it, and not all z06 have the same problem... then this is also your chance to clear the air on your position.
I would advise you pick the first of those 2 options. But you need to do whatever you believe is correct.
If you recall, he predicted GM could not fix the problem, as he believed every car had the problem. You strongly disagreed and that is the polite way of putting it. You literally mocked him as clueless and bragged about your knowledge of the vehicles.
At this point, from everything I have witnessed, I would advise you reconsider your point of view, we assumed you had already done so along the way and realized he was right, and were sharp enough to know to back off. Perhaps that's not the case. Please clarify your current stance on this topic for us.

Roxy, can you please explain how the fuel pump cutting out is endagering peoples lives? As I understand the issue, if a fuel pump stops pumping fuel and the vehicle goes into limp mode, you slow down. Simple as that. If I am wrong, please explain.
The conditions that this issue are reproduced under are something that an extremely small fraction of car owners will ever experience in my opinion. That being said, in my opinion, if the vehicle only goes into limp mode and slows down, and there is no threat to life then GM is not -obligated- to do a recall. That would simply be a TSB (technical service bulletin) for people that complain of the issue. The reason they wouldn’t do a recall in this instance (and I would agree on their stance) is the cost of doing a recall to fix an issue on several thousands of cars is foolish compared to how many people will ever experience the issue.
First and foremost, I am NOT disagreeing that theres a problem and you guys found it.. I am saying I don’t see how it puts peoples lives in danger and that in turn makes this much less of a pressing issue for GM..

No problem.
take one of us to a roadcourse... put a blinder/shade so that you can't see our hand hit your ignition switch, and when you are pulling 1.2 lateral G in a curve... It's fine with you if I kill the motor to your car when you least expect it.
it's cool with you if you are pulling 1.2 lateral G at 155mph right?
you're not going to panic? Wot to drag on the back wheels in the blink of an eye... at 155mph at 1.2 lateral G...
you've got it I bet right?
quick question... have you ever pulled 1.2 lateral G at 155?
now imagine you're doing it for the first time in your life... ever... and your car cuts out... because I shut off your ignition.
it's the same thing. Make sure you guys are next to a long line of trees or telephone poles, and show me why there's no drama or anything to be afraid of... as you pull the 1.2 lateral G and NicD kills your ignition.... put him in your passenger seat, not me.
you and he can show me why we are Just a bunch of drama queen pu**ies
or just do it on a cold day at sea level, and let NicD drive. I'll find you guys the perfect road, don't worry. It will strike when you least expect it at 155... it will be fun. Let's go... I'll film.
is my description adequate, or would you prefer we conduct the test with you 2 driving in your cars?
make sense yet... why this is a problem?
or is this going to have to be another repeat session... as it takes days/months/years to finally understand what I just said?

I understand what you are explaining about losing power at high speed, but I do not share the same opinion that “unexpectedly” losing power is going to cause danger. The car does not blow a tire or lock up the brakes at those speeds. That would be different and totally understandable. To answer you direct, yes, I have had a car shut OFF at over 150 so I can speak from experience. Additionally, you talk about there being trees around when you are doing 150+. Nowhere in the states (where your specific model was released and regulated) can you drive that fast legally unless you are on a track. So you are implying that you are doing speeds of 150+ in places you shouldn’t be. Irun4cops originally indicated he was doing these “extended high speed runs” in florida where he was able to reproduce the problem after a period of time at high speed. The problem is, theres no place here in FL that he could have been legally testing the car at those high speeds for that long of a period of time that I am aware of. Where am I going with this? I don’t think a lot of people using this car on a sanctioned track in a legal environment have this issue. The car was designed to be track -CAPABLE- and NOT as a full fledged race car. It can do a darn good job on the track but when you start doing extended runs at 150+ on public roads because thats the only way you can stay going that fast that long then you are changing the rules of the game. The car wasn’t built to do that. Sure you can break it if you push it past what its capable of. That doesn’t mean GM failed you though.
Second, no, i’m not with GM. I actually help to provide knowledge and instruction to many on this forum to mod their car in ways GM would certainly NOT approve of LOL

I got a JMS FuelMax voltage booster (PM2000GM2) to my automatic '17 GS. But we are in trouble as it burned two times. One capacitor part burn out always after ~1min when engine started (at simple idling). Our biggest problem is the user manual, NO ANY C7 manual. The nearest is for 2016 Camaro.
JMS don't answer ( I wrote many times). I think it's a problem too that I'm in Hungary....poor foreign client, nobody care... My friend installed a Magnuson SC and a Kooks headers with catted X-pipe. We got all parts (JMS too) and HPtuners from Jannetty Racing and a custom tune file too. SC and exhaust installed well, tune file uploaded too, everything was clear. But this JMS....we hate it.
But one more thing what is very interesting, I started to use the car without the booster (now third day). Is it possible that the stock fuel system can handle the supercharged engine? So it was a 100% stock GS and a basic Magnuson Heartbeat (no pulley and other extra mods) and a new exhaust system installed. I think ~550 - 600whp. I try to keep conservative driving but I made a few pulls and no any problem. The car accelerating nice, smooth, the shifting also good too. Ted from Jannetty Racing wrote that he feel I need the voltage booster but unfortunatelly they can't help too. Of corse I will sleep better too if one day we can install it. But we tried many times, it burn always. And nobody help. I asked Magnuson too, but it's not their problem of corse. So here is this JMS sh*t and can't install without a correct manual :-\
You! Yes you who installed this booster in your C7! How?? Anyone has photos or video about installation? We followed the Camaro manual but the wire colors, connections are not the same...of corse may we made a wrong connection somewhere, but we don't know where. Or my JMS has factory defect?
