I have an S14, and I am planning on bolting on a centrifugal supercharger, just to be different, but I started gathering my fuel equipment...i.e. 460cc injectors, top feed fuel rail, 255lph Walbro...and I wanted to run a standalone unit or piggyback unti for the air/fuel ratio adjustment and overall tuning...I checked around and it seems that AEM and Greddy have very popular systems, but again wanting to be an oddball, I wanted to try out a JET V-Force PCM. Has anyone heard about these or used one?

i havnt. Whats the price like for the JET one? If i remember correctly, the AEM stand alone system for the s14 is around $3000, which isnt cool....if the JET one is comparable to the AEM one, but costs less, id go w/it. But i'm by no means a specialist on engine management. Sorry!

They are around $200-$250. I read a description on their website and it said " A 20Mhz RISC microprocessor optimizes the ignition spark advance and recalibrates the fuel map for optimum horsepower and acceleration. Features: Modified Ignition Curve, Recalibrated Air/Fuel Ratio for Maximum Performance and Improved 1/4 Mile ET's, LED Read Out and an On/Off Override Switch." I believe the Greddy and AEM versions give you a little more visually with graphs and so on, but I think they are fairly similar. I believe the high-end ones come with presets or something to that extent, but I am not sure. I figured if they all do the same thing, then I could test things out and tune it properly, because I seriously doubt that I would retune it everyday depending on how I feel or if I were going to the track.

my thoughts exactly...hopefully a more knowledgable person will come along and comment, 'cuz when i get my SR20 for my 240, i have no clue what direction I'm gonna go in as far as engine management goes... Naturally, I want something good/reliable, but i dont wanna shell out the massive amounts of money AEM and GReddy want... (im a cheap-ass..)

We sell the v-force where I work (as well as the Venom, Greddy, the AEM, and A'PEXi, along with countlerss other programmers/tuners/chips/whatever for domestics and diesels), I'll be honest, they're crap. They mostly advance your timing, and use a generic fuel map to dump more fuel to compensate for the advance timing a little (but not much). And they use the same part number for almost all import applications, that alone should tell you something is rotten in the state of Denmark, so to speak. You are not going to be able to use it with forced induction or N2O, as the advance timing will cause detonation. This is not a stand-alone programmable system, it is not a piggy-back fuel controller, or anything like that.

If you are going to use a centrifugal supercharger (we also sell Paxton/Vortech, Powerdyne, etc.), I suggest you talk to the company supplying you the supercharger, they can steer you towards the right direction. Some develop a piggyback fuel controller in-house for thier kits. The new system for the 05 Mustang from Vortech actually uses a Diablosport Tuner, and I think some turn to Superchips Tuning (a spinoff of Superchips), to create the new tuning. You will not have the same R&D facilities they do however. You are probably going to have to use an A'PEXi Super AFC II to handle the extra fuel you'll need, you may not need an e-Manage or AEMs Stand alone management, but it all depends on your project, again your supercharger provider is going to be able to steer you in the right direction.

And BTW, those expensive stand alone management systems are well worth the money. They allow you to properly tune your engine and not blow it up. Speed costs money, how fast do you want to go?

Forced induction is not cheap by any means. Good luck.

Thanks man. I really don't want to spend any more money than I have to, but then again my 240 is my daily driver and being a college student, I can't afford to replace the engine. I thought about building my own s/c kit, but I think for safety and reliability I am just going to go with something like the universal import s/c kit by Procharger. Thanks for the advice though, it is really helpful. :fluffy:

The procharger kit does not come with brackets, belts, injectors, fuel pump, or piggyback fuel system.

The money you will spend will be more than what one of those kits that are vehicle specific costs. If you can't afford to replace the engine, you don't have the money to S/C the car. If you don't have the bucks, keep the car maintained, buy a couple things here and there, and learn to drive. You need a reliable car, time will come for crazy projects, and the money of course ;)
