Does the Boost Logic Port Injection Kit for A90 need a tune?

Yes. The Port Injection Kit for A90 Supra still requires custom tuning on EcuTek RaceROM. Boost Logic supplies an EcuTek Diff File with the settings a tuner needs to configure RaceROM for the controller, and it can be added to an existing RaceROM tune, but the final calibration must be done by a tuner for the fuel and hardware on the car.

Do I need the Visconti Flex Fuel Kit?

The kit needs the Visconti Flex Fuel Kit wiring and will not work with other similar flex fuel kits. If the car already has the Visconti kit, choose that option at the base price. If it does not, choose the sub wiring option for an extra $300, which supplies everything the car needs to run the system.

Will it work with my existing port injection setup?

It replaces it. On a car that already has port injection, this kit replaces all of the existing wiring, including the injector wiring, and none of the wiring from the previous installation is reused. Plan the job as a complete rewire of the port injection system rather than an addition to the old wiring.

Can the system run true flex fuel?

Yes. Because the factory ECM drives the port injectors over CANBUS, it can scale port injection fuel volume to the ethanol content in the tank. That removes the need to change the port injection tune for different ethanol blends, which Boost Logic notes other popular port injection systems are unable to do.

Are fuel injectors included?

Boost Logic lists the fuel rail, mounting hardware and wiring, but it does not list port injectors as part of the kit. Confirm injector requirements and sizing with Bulletproof Automotive and your tuner before ordering, so the rail, injectors and the rest of the fuel system are matched to the power target of the car.

I already have a flex fuel tune. Can I just swap the hardware?

No. If the car already runs a flex fuel enabled tune, the CANBUS hardware cannot be swapped out without an updated tune file from the tuner. Arrange the revised file before the installation so the car is not left without a matching calibration once the new controller is in place.

Description

Boost Logic Sequential Port Injection Kit for A90 / A91 Toyota GR Supra

Boost Logic’s Sequential Port Injection Kit for A90 / A91 Toyota GR Supra is a plug-and-play port injection system for the B58 that is controlled entirely over CANBUS, so the factory ECM drives the extra injectors. Because the ECM runs them, the car keeps true flex fuel operation with port fuel scaled to ethanol content, trims fuel on deceleration to prevent over-fueling, and uses fuel pressure monitoring to compensate injector pulse width when the low pressure system starts to run out of pump. It is aimed at high-power B58 builds on EcuTek RaceROM; it still needs custom tuning and is more than a lightly modified car requires.

Design and Performance

The controls were developed by Visconti Tuning. The CANBUS hardware can drive more than one PWM output, so the same system can run a secondary fuel pump, externally gated boost control, methanol or nitrous. Boost Logic supplies an EcuTek Diff File containing the settings a tuner needs to configure RaceROM for the controller, which can be added to a tune that already runs RaceROM as a starting point for the custom calibration.

Applications

Toyota GR Supra: A90 | 2020-2026 | 3.0L B58 I6

Notes

Choose Have Visconti Flex Fuel Kit if the car already runs the Visconti wiring, or Add Flex Fuel Sub Wiring for $300 if it does not
Requires the Visconti Flex Fuel Kit wiring; the kit does not work with other similar flex fuel kits, and the sub wiring option supplies what a car without it needs
Custom tuning on EcuTek RaceROM is still required; the Diff File is a starting point for your tuner
Boost Logic does not list port injectors as included; confirm injector requirements with Bulletproof Automotive before ordering
On cars that already have port injection, this kit replaces all existing wiring, including injector wiring, and none of the old wiring is reused
The kit replaces the Zeitronix CANBUS controller used in the Visconti Flex Fuel Kit; owners who want to keep an ethanol display should say so when ordering
Cars already running a flex fuel tune need an updated tune file from their tuner before the CANBUS hardware is swapped
Boost Logic lists a CANBUS controller as a $1,495 add-on, available through Bulletproof Automotive; confirm whether your setup needs it
The Sequential Port Injection Kit for A90 is designed for the 3.0 liter B58 GR Supra

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate.

Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
