hey guys, I have a person selling a Data systems vtec controller and he just has the unit itself. Here are some pics of it






Ok now my questions are, where would I be hooking up the wires to?? and what would I need to know to adjust my vtec settings????

you would hook the wires up to your ecu, and you would need to get on a dyno before you start changing settings

 

ok, great.

Does anybody know by looking at it if it's a relatively old or new model??? Any good words about this vtec controller???

 

 

Screw that POS. Get the real deal - V-AFC.

would you like to elaborate on your answer??? why should I get a "real" v-afc?????

 

Its just a simple vtec controller, you cannot adjust air/fuel settings with it. Give me a day to llok up the wiring for you, i had one the same and took the harnes sthat came with it for a VAFC and i have the wiring details written down somewhere. You can play about adjusting the vtec point but on a stock car you'll find that the factory setting is the optimum, unless you have changed cams in your car then you wont get much gain from it, it does have a rev counter which is sort of cool looking to have in your car, but apart from that it doesnt do much else (except remove the speed limiter on JDM cars, which is primarily the reason that i bought one for my car)

 

hey mugenracer- if you can please find me the wiring diagram, I would appreciate it.

Thanks for the help guys

 

If one of you guys has a chance could you please email me the wiring diagram, I've never managed to find one. A general run down on how they work would be even better but no worries if you don't have time.
I'll put the diagram up on my VTEC controller page of my site since I often get asked if I know anything about the Data Systems unit.

will do

 

It solders into the ECU wiring harness. There should be instructions. To truthfully know where your VTEC needs to be, you need to put it on a dyno to see what the engine likes. You and I could have the same identical setup, and my motor might light vtec at 5200 and yours might like it at 4800, do you know what I mean?

Once you get on the dyno, set VTEC at 2500rpm, make a run. Then set it at 7000rpm and make another run. Have the dyno operator overlap you two tq curves. Where they intersect is where you will want the VTEC set at.

Believe it or not, you will see minor A/F ratio changes just from dropping the VTEC down. It will lean it out up top a little more(not much.)

 

Thanks waffles...I'm going to see if the guy can drop the price due to the no instructions/manual. I'm going to be dyno tuning my car in the spring time so that's when I would be changing anything.

 

damn...that's the old one!! you should get the newer one...much smaller and prettier to look at.

 

Do a little more research!

"Data Systems controller allows you to adjust the VTEC crossover point and at the same time, automatically adjust the fuel and timing."

 

I now have a VTC82X fitted in my JDM ITR, theres a load of different settings on it P2/P4/P6/P8/P12etc and within the P settings you can adjust something +/-30 points (which i presume is the air/fuel. the controller is set at program 4 from the factory when i changed it to program2 and took a test drive, i noticed a big difference while above 5700rpm it just pulled way harder! I have no idea what each setting is and dont want to lay around with it till i get the instructions (which according to the US R-Spec site are available in english but theres no email address in which to contact them!!!) I just reset it for now till i can find out what the hell it can do, but from messing about with it, the VTC82X is a lot more than just a vtec controller.....i realise i said above its just a simple controller, well its OBD1 brother didnt have all the settings that the OBD2 controller has and i was referring to it above.....
