EPROM with ZE VRIS points
I might be able to offer the PT community, EPROM for 94 PGT, MX6 with ZE vris points but the rest beeing configure for the 03. The only change is the VRIS points, the rest (fuel map, ignition timming will stay unchanged). The reason why the rest is not beeing touched is because two years ago I had 15 EPROM programmed for my ZE and timming didn't affect much my output on the dyno. I didn't bother with fuel because I have a adjustable fuel pressure regulator to begin with.
The price won't be expensive, we're looking at $100-150US per chip. All you need to do is install a socket for the chip and remove the original chip. This can be done by a computer shop that can repair motherboards, this should cost $20 to have it done. I might be able to provide the socket as well.
For those who were looking for a VRIS control just to have the ZE VRIS points, this is the fix. VRIS point is only a function of intake manifold design (runner length, runner diameter). Camshaft, block size, headers, exhaust DO NOT AFFECT VRIS POINTS.
The mod is important for those who have a ZE intake manifold since you want you VRIS points to be configure to get the most power from your engine (especially between 6200-6800rpms). At 6250rpm the 03 VRIS close, if you have a ZE IM you want your VRIS to stay open 'til 6800rpms.
Like most of you know, if you have a ZE IM your VRIS needs to be update from the 03 VRIS points. Expect 4-5whp between 6200-6800rpms. Expect even more power if you have regrinded cams with duration above ZE spec cams.
I can also get your 03 cams regrinded to a more aggresive grind that is very streetable, check my other thread in the Bulk Buy section.
