So I'm at a Crossroads on witch system to buy, school me on why I might need Peak and hold injector driver over the other. This is the only thing keeping me from buying one system or the other.

Surely someone has to have knowledge on the subject. From the little bit of research I've done about it, it's my understanding that if I wanted to run something like a 550 label an hour injector or something crazy like that I may need the peak and hold injector driver

Give it more time. Not that many people here know the difference of what you are talking about

Well you give zero information about what you're dreaming of building or why you might even need those injectors !

What is a peak and hold signal? A peak and hold signal is a complex signal used to operate a low impedance injector. Peak and hold signals have two parts: a high initial current used to quickly open the injector and a low secondary current that is sufficient to hold the injector open until the end of the pulse. The low secondary current allows the injector to close more quickly since it takes less time for the weaker electrical field to collapse. Because of the two-step nature of the signal and the rudimentary construction of fuel injectors in the 1980’s, low impedance injectors of that time were more preferable than high impedance injectors for high-flow high performance applications; they could deliver more fuel more reliably than comparable high impedance injectors.



What is a saturated signal?

A saturated signal is a simple signal used to operate high impedance injectors. A single intensity signal is sent to a fuel injector which causes the valve to open and remain open until the signal has ended. The new technology used in the design and construction of today’s high impedance injectors allows much larger flow rates, much better response times, and much more predictable low pulse width operation than previous designs – all without overheating. This means that low impedance injectors are no longer the peak of performance when considering fuel injectors.

Found this and much more through a quick google search.

Wow .boB! That answered many of my questions on injector operation! Thank you!

That's because, I didn't want it to be about my combo.

Thank thank you very much for posting, this definitely explains everything in great detail.

This has nothing to do with my statement above....

Sorry I quoted the wrong the post, I was talking about Stevie turbos post.
