Vi-pec http://www.vi-pec.com/ im looking at upgrading from nistune to one of there replacement boards was recommended to do so by Mark at MRC after a lengthy conversations with him i now know why after been shown how much more detailed vi-pec are compared to a nistune. result should be more power though out the rev range all the way to 7500rpm and a smother tune with a nice power curve, ability to go bigger turbos in the future which i may do with out being restricted by afm's size or ability to reading the air flow no need for selin kit and many other benefits if i do change. has anyone used, heard or tuned one of there ecu's before or any helpful feedback would be greatly appreciated before i bite the bullet ill be pushing 360 370kw range atm if thats important thanks.
I honestly think Nistune is by far best bang for buck. All depends on the ability of your tuner though what you should go for. I taught myself how to tune, have tuned quite a few Z's including my own which makes 405RWKW with Nistune so it's well capable of attaining the figures you are chasing.
Vipec's are good and priced accordingly. The Skyline guys rave about them. Depends what you need though. Can you do 400rwkw with Nistune? Yes. Can you do it better with a Vipec? Slightly. I wouldn't upgrade unless you have the cash burning a hole in your pocket and you are going to use some of the additional features like data logging, PID boost control, fancy O2 feedback etc.
Unless you're making extremely high HP levels or want all the little goodies like launch control etc built in, you're better of staying with NIStune.
around $1800 for the board that fits in our ecu + 8 to $900 to tune but i could sell off what ive got nistune, selin, 2x new oem afm
im running a vipec on my vh45 conversion . there not really that dear once you consider its a ecu , electronic boost controller and lets you get rid of the air flow meter . The nistune is using a ecu from 1989 so its no suprise that a 20 yr newer ecu is better .
big reason why i would change is i would like to go big hp in the future so do it now or later and with vi-pec, ems, motec or haltech Ps' 2000 Vi-pec is the cheaper one compared to others at its level with similar features.
For that sort of money I really would want to go something a bit more main stream. They have R32-33 boards, same plug as Z32, with a known problem list for the R32-33, nothing for the Z32. Probably have to go through issues developing the setup and wiring pin out. Not to say it cant be done but if you want the plug in thing Haltech have something similar but specifically for the Z32. http://www.haltech.com/store/index.php/platinum-pro-plug-in-nissan-z32-fairlady-300zx-kit.html Sounds like extra risk for less return to me.

It also seems the the vi-pec may be closely related to the linkplus G3/4, searched their website for 300ZX, 2 references, 1 to a gen 2 unit and a 300ZX fuel pump.
there is no vipec for z32 last time i looked but the skyline one can be made to work by changing a few wires and a bit of the set up theres no real issues for a work shop that knows what they are doing installing it .
Sure anything is possible, but why not use a supplier that has committed to the Z32, has a wider base of tuners experienced with the software, better software, better resale and they can probably provide you with a base map. And Haltech is "designed and manufactured in Australia" :br: Sounds like extra risk for less return to me, going with the Vi-Pec/Link.
I agree with you that nistune is best bang for your buck my tuner probably would agree also but his installed nistune thousands of times he says once you go over the 300+kw it starts to lose its tune ability and gets less and less as the map gets stretched out more, so you might get a good top end power figger but your power curve starts to go like this ~''' with Vi-pec you can split the cells up till you get up to 36 x 26 cell graph so you can really fine tune it + all the features it has over nistune. hope this makes sense the way i explained it i probably don't really need it now but later on after i go bigger turbos i would need it what turbos do you run to get 405kw rs's ?
vipec Recently whilst at Willowbank one Wednesday night, i was shown this on an Evo and a r33 with a strong RB26 (12.1 @ 141mph on 19's with fanbelt tyres) It definately had some good features antilag , boost control as mentioned ,
The Haltech Platinum Pro Plug In does also apparently. (see feature list above for boost control details.) [YT]DG7wJCtwy-o[/YT]
