vein pressure convetor for ca18det, eliminates mafs... $200 isn't bad, if I could afford it right now I'd get it.

[ca18detdrift]

haha this is mine! If anyone bids you will be sniped! lol

[knightrider]

good luck getting it tuned right cuz not even hks can tune it correctly. i had one that came with my CA, and never got it running right. id rather run a z32 maf.

[sdtouge]

is your car back in commision now? you doing thatdrift circuit event lol coming up? should be lamest event ever 100 people like 4 runs all day

[c-rad]

Yeah.... VPC is NOT worth it. If it's tuned for the stock setup, then you still need a piggy back to tune. I doubt you'll be able to find a modified eprom for the VPC. Z32 maf is good for close to 500hp... and can be run in a blow-through setup....

[slownslurious]

get it tuned by an HKS dealer, whats the problem?

The point of the VPC is to replace the MAF when it becomes a bottleneck. I challenge anyone on this board to max out a Z32 MAF.

As for the HKS dealer... the shop down the road is an authorized dealer and they don't know their head from their ***.

I had a friend who had this in Japan on his ca18det. He said it was simple to tune (he was also the one who recommended me to get it). I'll ask him about it some more, but thanks for the warning guys, now im a little hesitant on getting this...

[slownslurious]

yeah that and the numerous quirks that mafs metered cars experience, and going blow through brings its own problems (plastic mafs housing, oil on element, etc). I've seen a very very high powered supra that used this (along with the Fcon and GCC) and his car ran very well, and had been tuned by an HKS pro dealer.I'd say problems experienced with devices such as this are often induced by user error.

Don't forget that HKS has dropped support for the VPC 1, and only offers replacement parts for the sensors and wiring, so finding a HKS Pro Shop (HKS Pro Shops have dynos, which you will need) may or may not be prepared to work with a VPC...esp. since HKS never supported the CA18DET in the US.

[rexhunta]

This kinda sounds like the problem in Australia.. once a year the little nice guy from HKS Kansai visit the land down under and tunes everyones Pro F Con V's and such special HKS things, usually at state captials.. my mate has an evo 6.5 tme which had to drive 4 hours with it on a trailer, just for the special event.. and it cost him a ****load too.. but he did well off it, so least theres 1 positive

well the vpc is the brainchild of one person at hks, i forget his name, but basically he worked on it all by himself. he was for a while here in the US, but got deported back to japan, that is when hks stopped supporting the vpc here in the US, because no1 knows how the damn thing functions. you can still get a US rom tune for the thing from a hks pro dealer, but anything else and your screwed, and even the US cars have very limited tunes available and no custom tunes . if you wanna get rid of your maf, go standalone, otherwise, go z32

everyone is so negative! I bet none of you guys have ever even used a VPC. I've seen a very high HP'd supra using one and it was very driveable.

Why try to reinvent the wheel? People know what works. VPC has been out for years. If it was a viable tuning device, don't you think more people would be using it?

Every instance of a VPC equipped car is HIGH powered. Meaning it has outgrown the stock MAF...as I stated earlier.

[CA19DET]

the VPS works with the GCC together they are very easy to use, have a couple friends that use(d) them, the GCC is used to fine tune the fuel/ignition slightly

SDS>VPC

Hehehehe, I rule!

[ca18detdrift]

Well guys I got it, I'll let you know how it turns out once i do my swap!

[Dattebayo]

Now all you have to do is make some serious crazy nutz power and stuff.

[slownslurious]

good luck, I'm sure it will work just fine.

[sdtouge]

if i were you, at first i would start you car and getting running ok first with out that thing, just use a nromal maf setup. then if/when you have problems (i had lots lol) its one less thing you need to look into.

good luck!

um i have used it, i had a VPC and GCC that came with my CA clip, and i ended up using none of the goodies that came on my clip, i installed it stock, i tried running the vpc, and couldnt get it to run right, a/f was all over the place, and the gcc i had was all but worthless. i finally plugged in the maf, and my car ran fine. got rid of the vpc and the gcc for 175$. the only reason i could see to run one is for the bling factor or if you are pushing more than any maf availiable will allow. which i find hard considering the options availiable. if you really are worried about maf restriction, use a ford lightning maf, i can fit my arm through it and we have a 650whp b13 sentra at the shop running a tuned stock ecu and a lightning maf... and a big *** turbo, with no problems. you might say, well a map system is better, well, then get a standalone that is designed to use one, its less headaches than using some ancient converter.

[slownslurious]

are you an HKS authorized dealer?might have something to do with your difficulties getting it tuned.

[teambuiltnissan]

no problem with VPC on my ca18det. I have a access to the chips. ca18 sr20 rb20 rb25 vg and other.

it is great tool if you know what you doing.we have tested up til 880cc injector on VPC with pt67 on 10psi.. runs great. idles at 15.3ish WOT at the top of map is about 11.6 on street.

oh by the way.. Z32 MAF is great, but I maxed Z32 MAF at 19psi on my ca. even with blowthru. I am running d-jetro on sr20der power fc. 5V reads at 6800rpm where my rev is set at 9500.

I guess depands on how use the tool, or who you know.

[fallen180sx]

i'd use it just to vent my bov
