Hondata FlashPro for 2004-2014 Acura TSX

Hondata FlashPro - 2007-2014 Acura TSX

If you've thrown bolt-ons or boost at your TSX and you're still running the factory tune, you're leaving real power and drivability on the table. The Hondata FlashPro is how you actually take control of your K24. It's the standard for tuning K-series Hondas, a hardware-and-software combo that plugs straight from your laptop's USB into your car's OBDII port and opens up live tuning, datalogging, and full custom calibrations. Intake, header, exhaust, cams, turbo, supercharger, whatever you've built, the FlashPro is what lets you tune around it instead of hoping the stock map can cope.

What It Actually Does

The FlashPro flashes custom calibrations right to your ECU, with no ECU modification or cracking the case required, you just plug into the OBDII port. It comes with Hondata's FlashProManager software, which includes a library of 56 built-in base calibrations for popular bolt-on combos, so you've got safe starting points for common setups. The datalogging is the real strength, capturing both live and stored data so you or your tuner can see exactly what the engine's doing and dial it in off facts instead of guesses. Live tuning means your tuner can make changes on the fly while the car runs, which cuts tuning time way down and sharpens the result. You also get custom laptop gauges to watch your vitals, dual calibration storage so you can flip between two tunes, and the ability to read and clear your own diagnostic codes.

Don't Just Load A Base Map And Send It

The base maps are a safe place to start, but they are not tuned for your specific car. Every build is a little different, and a base map doesn't know what yours is doing. Get your car professionally tuned after you install the FlashPro rather than flashing a base map and driving it hard. If you're running anything serious, a turbo, a built motor, aggressive cams, get it on a dyno and tuned properly. That's where the FlashPro earns its money, and it's how you keep a built K24 happy and reliable instead of grenading it on a generic map.

Pick The Right Version For How You Drive

There are two versions, and you want the right one. The FlashPro Race is for off-road and track use only. The FlashPro CARB Legal is street legal in all 50 states. If this is a street car, go CARB Legal; if it's a dedicated track or off-road car, the Race version is your pick. Choose based on how you actually use the car.

Running A 2004-2006 TSX? Get The Complete Kit

The FlashPro is set up for the 2007-2014 cars, but you're not left out if you've got an 04-06 TSX. To run it on the earlier car you need a 2007-2008 ECU plus the Hondata CAN wiring, so we offer a complete kit that bundles all three pieces together, the FlashPro, the CAN wiring, and the ECU, so you get everything in one box instead of sourcing parts separately. This kit is specific to the 2004-2006 TSX. If you've got an 07-14 TSX, you just need the FlashPro on its own.

The 04-06 complete kit includes:

• Hondata FlashPro
• Hondata CAN wiring and programming adapter
• 2007-2008 Acura TSX automatic core ECU (37820-RBB-A71)

About The ECU - Works On Automatic And Manual Cars

The kit ships with a 2007-2008 automatic core ECU, and it works on both automatic and manual 04-06 TSX. We use the automatic core because the manual units have become very hard to source, and Hondata supports running the automatic ECU on a manual car. Here's what that means depending on your transmission:

• Automatic 04-06 TSX: straightforward, the automatic ECU is a direct match.
• Manual 04-06 TSX: you flash the ECU with a manual calibration, which FlashPro Manager 1.7.2 or newer does directly. Two things to know going in: reverse lockout will not function, so be deliberate on your 4-5 and 5-6 shifts so you don't accidentally grab reverse, and don't drive on the automatic calibration, flash the manual cal first so the drive-by-wire behaves and the car isn't throwing codes.

How The Install Works

This is a real install with a dealer step in the middle, so here's the sequence before you start. Read it through so nothing catches you off guard, since part of the wiring is very hard to undo once it's in.

1. Install the CAN harness. Pull the glovebox and find the green CAN connector in the upper center of the dash, behind the audio controls. The supplied adapter's red and white wires go into that connector, then the adapter runs down to the DLC (the OBDII port) to the left of the driver's knee. At the DLC you'll move the gray wire from pin 14 to pin 1 (for immobilizer programming), add the white wire to pin 6 (CAN program high), and add the red wire to pin 14 (CAN program low). Double-check the green connector wiring before you seat it, because it's nearly impossible to remove later without tearing the dash apart.
2. Swap the ECU. The ECU sits in the center, between the driver and passenger footwells. Pull the driver-side kick panel, peel the carpet back, pull the passenger kick panel and the AC duct, unclip the connectors, and pull the two 10mm bolts. It's a tight fit coming out. Drop the 07-08 ECU in its place. On a manual car the automatic ECU simply leaves one connector unused.
3. Have the dealer match the immobilizer. This is the step you can't skip and can't do at home. The car will not start until the immobilizer is reprogrammed to the new ECU. Make a dealer appointment ahead of time, drive there with the harness installed, and have them enter your VIN into the ECU and run the "replace ECU" function to match it to your immobilizer. Manual cars, read this: the dealer's immobilizer tool normally expects the car to be in Park with the brake pressed, which a manual can't do, so this step can take some extra work on a manual car. Follow Hondata's current 04-06 TSX FlashPro instructions and FAQ for the exact procedure, and it's worth calling your dealer ahead so they know what the appointment involves.
4. Register and flash. Register your FlashPro and lock it to the ECU, then load the right base calibration. For an 04-05 TSX, use the supplied 04-05 base cal; the 06 engine is identical to the 07-08, so an 06 uses the closest 07-08 cal. Manual cars flash the manual calibration here. You can drive gently on the base cal until you get it properly tuned, but a base map is a starting point, not a finished tune.

If you're not comfortable pulling panels and re-pinning a connector, this is a reasonable one to hand to a shop, especially since it already requires a dealer visit for the immobilizer step.

Before You Buy

All FlashPro sales are final. FlashPro units are non-returnable because we can't verify whether they've been married to a vehicle. Once you flash a tune, the FlashPro locks to your ECU. You can unlock it to sell it or move it to another car, but you have to do that yourself through the FlashPro software. And get your car professionally tuned after install rather than loading a base map and driving hard, especially if you're running a turbo, built motor, or aggressive cams.
