I'm currently shopping for an alternative to my VAFC bandaid. I have a non OBD ECU(PR3) so my options are pretty limited without converting to OBD1. I've tossed around the idea of converting to OBD1, but I'd like to avoid it. Until recently I was going to go with a Zdyne, but I'm looking at about $1100 for it (after options and tax-live in Cali) After the cost of buying a laptop, I'm lookin at $1500(luckily I already have the 450 injectors)
This brings me to the ask the question, how is the EFI PMS? I know it's an older system, but for my application it might be a better route to go. By my application I mean- occasional DRAG racing, but mostly looking for a reliable daily driver boosting 10psi on a internally stock B16A. Looking around I see systems for $500-900, since I won't need a laptop that saves even more. It also looks like the system is available for OBD as well as non-OBD cars.
Any input is welcome, all I ask is not to turn this thread into a Hondata vs. PMS vs. standalone vs. TRUE standalone argument. Thanks fellas...

I am currently running the efi pms on my internally(for now stock b16. The efi system works okay, but isn't as nice as a hondata, etc. I got it because my tuner is very familiar with it and I though 8 psi would be enough. Boy was I wrong. Compared to the vafc setup I used to have, the efi is significantly better, but if you plan on building for the future, I would buy a hondata or aem.

 

What are some of the things you don't really like about it?
Did you dyno your 280/wheels on it? If so, that's

 

the pms combined with their interaq software (which requires a laptop w/ win95 OS) can also be used as a standalone. as a piggyback it modifies the signal coming from the ecu (as opposed to before the ecu like most other piggybacks) to your settings. in standalone mode, it completely ignores the ecu signal and lets you plug in your own values for fuel, timing, or both

 

I had the pms before and now I have the z-dyne. The pms worked pretty good but didnt have as much adjustability as the z-dyne does. I personally like my z-dyne better. Theres just more features and adjustability. HTH

By reading the website, it appears you can only adjust the timing and Fuel curve in 2K RPM incriments, is that right? Also, Fuel adjustments are in 2% and timing in 1 degree steps. If so, that's kind of a big margin for error, it would seem. Plus, the datalogging option requires the software and a laptop anyway.

Thanks for the input. I'm still leaning more towards the Zdyne, just wanted to explore other options.

 

The adjustability on the pms sucks. It isn't able to fine tune as well as a true stand alone. You are only able to adjust fuel and timing for 2,4,6,8,000 rpm. It is fairly dated technology. It was a waste of money on my part, but I won't make this mistake again. I would suggest the hondata or aem. Good luck!

 

Yeah, but there was a problem with my tps so we could finish it...

 

Yea thats pretty much the reason I got rid of it.

The only thing I dont like about the z-dyne is no data logging.
