When swapping a Ford 6R80 automatic transmission into your hot rod, there is a good chance that you will lose the gear selector position information. The reason being is that the 6R80 selector position is encoded as a PWM signal most of the time, making it very hard for aftermarket ECU's to decipher the signal.
The 6R80 Gear selector range converter solves this by "tapping" into the signal wire that comes from the transmission and converting the PRDSL signal to an ECU-friendly 0-5V signal that can be used by a standalone ECU and broadcast to a dash or other devices.
Please note that this converts only the selector position signal.
Our MAP sensors are top of the line when it comes to motosports pressure transducers.

If you want the best combustion sealing solution on the market for your GTR, look no further. Our Extreme Performance fire ring kits have been developed from the ground up to overcome the problems usually found on other systems and provide the greatest sealing capacity.
What makes our fire rings so special?
SURFACE AREA AND CLAMP SPREAD
Our rings are the widest on the GTR market. Made from the same material the Top Fuel teams use, we have maximized the available sealing area through trial and error in order to provide a ring that provides the maximum seating surface in order to spread the clamping load over a wider area and prevent cylinder head warpage during torque.
GASKET THICKNESS
After many years of testing, we have come up with the optimum gasket thickness that works best in all-out engines. On a GTR engine, the head gasket thickness determines the center of the variable cam gears, which need to be precisely aligned. Our fire ring and gasket combination is 0.010" taller than the OEM gasket, which allows machine shops to mill the cylinder heads to perfection without fear of displacing the VCT alignment.
CLAMP SHARING
In a fire ring sealing system, the gasket is usually used only to seal the oil and water passages and 100% of the sealing is left to the rings. In our Extreme Performance system, we have carefully measured fire ring crush height so that the copper gasket shares about 15% of the clamp force. This clamp sharing ensures a complete gasket seal and uses the awesome properties of copper to provide a secondary barrier to combustion leakage under extreme boost.
COMPATIBLE WITH SLEEVES
Our fire rings have been carefully dimensioned to be compatible with both stock and sleeved blocks. On dry sleeves, our rings seat entirely over the steel. This provides a failsafe so that during clamping, all of the force is exerted onto the cylinder sleeve and not on the surrounding aluminum, pressing the sleeve into the block and preventing any "sleeve drops".
Kit includes:
Two copper gaskets
6 fire rings
Instructions for machining groove
We recommend CNC machining of the fire ring grooves in the engine block due to the extremely tight tolerances of our gaskets. We can also provide CNC machining of the engine block as a service. While these can be installed on the cylinder head, we recommend engine block installation so that whenever the cylinder heads need to be serviced, they can be surfaced without worry of disturbing the seating groove. Seating the rings in the block also ensures correct gasket alignment and prevents the rings from dropping during installation.
This module converts the digital signal from a flex fuel sensor into an analog signal that the R35 ECU can process. Simple plug and play installation makes this module a breeze to use. All of our products are proudly assembled in the USA.
Flex fuel composition sensor sold separately.
Signal output is ratiometric:
0.5V = 0% ethanol content
4.5V = 100% ethanol content
Less than 0.5V or higher than 4.5V indicate contaminated fuel or sensor/module malfunction

If you want the best combustion sealing solution on the market for your street GTR R35, look no further. Our Ultra Performance fire ring kits have been developed from the ground up to overcome the problems usually found on other systems and provide the greatest sealing capacity. This kit is suited for street engines that will make under 1800HP. The composite gasket material ensures a perfect seal against coolant and oil and we have tested it to well over 2000HP. However if your engine exceeds our recommended rating, you can also look at our Extreme Performance kit.
