I can understand the vtec-input signal being off all the time. You don't have a vtec ECU. You will never have a live vtec signal from the ECU. If your VAFC is never setting the vtec out signal high, then that right there may be your problem. What RPM is your VAFC set to activate Vtec at?

Are you running stock headers? I read in your sig that you have a 88DX w/ B16A. In all likelyhood, its a B16A1. B16A1s are very picky about the placement of the O2 sensors when you run them with the stock PW0/PR3 ECUs. The ECU will actually lean out 2 cylinders at a time in closed loop and...

it's going to depend on which ECU you are using to run the motor. Assuming you have a JDM/USDM P30 or P72, you will need to add wires for: -Vtec solenoid -Vtec pressure switch -knock sensor If your motor has the wack ass secondary butterflies in the inatke manifold, you will need to add a wire...

My homefry Nick has his B20Vtec running off a chipped P28. He runs low 13s on steet tires in a CRX. I'd say that is an acceptable solution. The tune he made himself was made with Crome (a free romeditor available on PGMFI) with a lot of trial and error. It took him several hours of driving...

I'm sorry, but I'm going to have to disagree with the majority opinion here. VAFCs have no input for a vtec pressure switch. VAFCs have a single wire output for vtec that goes directly to the solenoid. VAFCs make no use whatsoever of the circuitry in the ECU to activate vtec. I know this...

you try manually engaging it by connecting the clutch directly to +12v and bypassing the ECU? Not all ECUs have the circuitry to control AC. It's an option on the ECU just like on the car.

any fix that can be done with a pair of needle nose pliers or dikes is just too easy to pass up...

...the 25mph speed requirement, but would apply equally to your situation. At a minimum, you are looking at a chipped ECU with custom program. The *easy* way of doing this would be to add a wire from the Vtec pressure pin on the ECU (look it up - I don't remember off top of my head) to ground...

check your wiring. The VAFC can activate vtec with a non-vtec ECU. Did you run a wire from the VAFC to your vtec solenoid? That's all you really need to do...

wise words. square ECU vs rectangular easiest way to tell. If your friend needs a program with EGR disabled, tell him to email me and I can either email him a bin to burn to a chip or send him a pre-burned chip.

Correction: 66P507 chips for OBD2A (96-98) cost between $37 and $60 depending on where you buy them and how many you purchase. In addition to the chip you must purchase or build a programmer, and find a program. This isn't that tricky, but its not cake like OBD0/OBD1. The parts are...

Hondata make a quality product. If you want good support and proven tools and are willing to pay for it, I can't recommend it enough. If cash is more of a concern to you, I'd head your ass over to http://pgmfi.org and look at what some of your fellow enthusiasts have been doing. BTW...

And I'll have to second everything James said. Hondata make a fine product, but there are other things out there that will let you run boost reliably on a honda. Both James and myself are in a positition to offer you both the hardware and software to run a boosted car. I have a chipped P72...
