The leaning tower of Mectric Motorsport Electronics. 😅

Whether you need a compact 4-channel PDM or an MTC16 Transmission Controller, Auto Tech Wiring & Tuning has you covered.

With years of hands-on motorsport wiring and aftermarket ECU tuning experience, we build systems that are designed to perform and survive in harsh environments. We know what works because we’ve tested it on the street, the dyno, and the track.

Quality wiring isn’t where you cut corners. Don’t be fooled by cheap prices and half-finished work—doing it right the first time is always the better investment.

Tough flex-fuel Barra out the door. 🔥

Stock Barra running a haltech Plug-in ECU, sensor package, and psr_pulsarturbo on a flex fuel tune.

✅ 430kW on E85 @ 17psi
✅ 365kW on 98 RON @ 17psi

We ran out of fuel pump before we ran out of turbo, so there’s plenty more left in it. It also desperately needs valve springs before we lean on it any harder, but as it sits it’s going to be an absolute weapon on the street.

Built and installed by saautoinstalls, with tuning by Auto Tech Wiring and Tuning.

Tried. Tested. Proven. Results backed by experience, not guesswork.

Running out of outputs doesn’t mean running out of options.

Custom concentric twisted motorsport harness for a mectricmse uPDM, dedicated to controlling the complete nitrous system on this S15—including the NOS solenoid, purge solenoid, bottle heater, and bottle pressure sensor.
With the haltech Elite 2500 out of available I/O, we’re using the uPDM’s custom CAN functionality to emulate a Haltech CAN I/O Expander, giving seamless integration with the Haltech ECU while adding intelligent power distribution and control without extra hardware.

Clean wiring. Smart CAN integration. No compromises.
