All you need to do is get the base s200 system, then add any of the optional upgrades that'd you like to have. Easy as that.

I've found that if you setup the CUSTOM table using A/F values for the voltages rather than Lambda, it works just fine and saves them in the registry.

You could install the 3B with no problems in your P72. However, you can't use the p28 Chip in the P72. You would need a dealer to burn a basemap for your P72 ECU.

Don't scrimp on the tuning part. I saw a cracked cylinder wall just because it wasn't tuned right. and don't forget not all engines ...

Yes, it will work.. if you don't buy his ECU, you can just put his EPROM into your p72.. however your knock sensor will no longer function since its a p28 program on the ROM.

Just noticed this today, if you highlight a section of any table to make a change by pressing "J", make a change, then click on "EDIT -> UNDO" and then try to change the same highlighted area again, it will default to the previously changed values you made prior to the UNDO...

Kind of hard to ...

I'm pretty sure the i'm correct in my second post.. We did it the first way and the car still threw a code (from what i can remember) so we switched it.

I know for a FACT that one of the 2 is correct.. and i'm 99% sure its the 2nd post. So just wire it up to a relay, and try it one way, and if it ...

Just an update.. I went over the wiring again, and I have it backwards in my previous post.. The VTP voltage follows the VTS, so just wire up a relay that will trigger 12v with the VTS and also send 12v to the VTP when VTEC engages. At idle and off-vtec, the VTP needs to see 0v.

Your welcome

Yes.. thats what I'm saying all along.. if you add too much fuel via the VAFC, then it will be increasing the voltage of the MAP that is going to the ECU.

So will adding too much fuel via the VAFC push the voltage up to the MAP?

No.. the VAFC modifies the signal coming FROM the MAP to the ECU.

I have a normally aspirated GSR and I am having troubles with my MAP sensor. The dealer says that I am getting a high input voltage from my VAFC to the MAP sensor or to the ECU. Does anyone know what the voltage range is on the MAP sensor from idle to full throttle?

I figured someone here might ...

The problem is because you don't have the oil pressure sensor on the JDM head. You have to wire in a relay to trick the USDM ECU by using the VTS signal as the oil pressure signal.

Basically when the the VTS is activated (12v), the VTM signal needs to drop to 0 volts and when the VTS is 0v, the VTM ...

It replaces ALL the regular bolt on stuff.. All you need is the Hondata, the turbo system and larger injectors.. Thats it! LITERALLY.

Minimum is stage 2b.

Your right.. but the problem here is that you would never be running 5.25 degrees TOTAL ADVANCE from say 4000rpm to redline at WOT in column 10.

Even at close to redline, your total advance at 0psi should be at pretty much stock values which range from 27.50-33.00ish degrees. Thus even if you ...

You can't just arbitrarily decide on an A/F... you can choose a starting target A/F and tune the vehicle to that, but the only way to find out what the best A/F is, is to put the car on a dyno and start trying different A/F ratios.

Usually, you want to tune the car to one A/F (ie. 13.2 for NA ...
