The TCFI kit includes the WEGO IIID dual channel wide-band exhaust gas oxygen interface that allows quick auto-tuning on a dyno or on-road during actual riding conditions. The kit includes Bosch LSU 4.2 wide-band sensors for both front and rear cylinders. The TCFI solves tuning problems with highly modified engines. Competitive “band-aid” products that interface to the Delphi® controller still rely on speed-density fuel control. Long duration/high overlap camshafts wreak havoc with manifold pressure - especially at idle and cruise RPM. Speed-density based fuel control simply can’t cope.

FAQ

How do I tell if a part will fit my ride?

Not sure if a part fits your ride? No problem—we’ve made it easy! You’ll find a fitment tool right on every product page (and on our homepage) to help you check compatibility with your vehicle. If you’re still unsure, just reach out—we’re always happy to help you find the right fit.

Does Motomentum price match?

Do you offer warranties on your products?

At Motomentum, we stand behind the products we sell because we only carry brands we trust. Most of our items are covered by the manufacturer’s warranty, but don’t worry—we’re always here to help. If you ever run into an issue, reach out to us first. We’ll gladly assist with warranty questions and help you navigate the process to make sure you’re taken care of.

Motomentum accepts returns within 45 days of delivery, as long as items are unused, unaltered, and in resellable condition with all original packaging, tags, accessories, and paperwork included (some exclusions apply). See our full Return Policy or start a return from your orders page.

How much is shipping?

If you’re in the continental U.S., odds are good you’re getting free shipping. And how fast is it? Most orders arrive in 2–3 days. Sometimes faster, especially if a warehouse near you is locked and loaded.

We ship most items free of charge, unless it’s the kind of thing that won’t fit in your trunk (unless you drive a box truck). Oversized stuff may cost a little extra—but we’ll always keep it real with you upfront.

Need it even quicker? At checkout, you’ll usually have 2 express options ready to go—because sometimes, you just can’t wait.

Bottom line: we want you to get your gear fast, at the best price, with no surprises. Check out our Shipping Policy to see all the details.

Can I pick my order up instead?

Absolutely! Just give us a quick shout before you order so we can double-check things for you. Since we ship from multiple locations across the country, your item might not be at our HQ—but don’t worry, that usually means it’ll reach you even faster!
