Hondata's 2019 Acura RDX tune brings the mid-range torque

One of the big advantages to the era of turbo Hondas is that there's plenty of horsepower and torque left on the table for tuners to take advantage of. One of those companies is Hondata, and following its upgrades for the Civic and Accord, it's now tuning the Acura RDX luxury crossover. The RDX uses a turbocharged 2.0-liter engine similar to those in the Accord and the Civic Type R. In stock form, it makes 272 horsepower and 280 pound-feet of torque. With Hondata's Stage 1 tune, the company says that horsepower increases by about 10 across the rev band. Looking at the dyno graph, it also appears that peak horsepower increases by about 5 horsepower, and peak torque is up by about 15 pound-feet. Peak torque also appears to arrive sooner, and most of the torque curve seems to be up by 10 to 15 pound-feet. The increases in power and torque are available in all four of the RDX's drive modes. The Stage 2 tune increases power torque even more in Sport and Sport+ modes, and keeps Snow and Comfort modes at Stage 1 settings. Peak horsepower looks to be up about 10 over stock, but the mid-range sees as much as a 28-hp increase. Peak torque sees a huge jump of about 45 lb-ft over stock based on the dyno chart, and it's available even lower than the Stage 1's peak torque. If this all sounds good to you, you can order up a Hondata FlashPro computer for your RDX right now. It costs $695 and comes with the handheld computer for uploading or removing tunes. RDX owners in California should note that neither tune is currently CARB legal. Related Video:

2021 Acura TLX A-Spec Long-Term Update | Infotainment system hits a pothole

The first few thousand miles of motoring in our 2021 Acura TLX A-Spec long-term test car were problem-free, but that changed after we took it on a spirited drive through the winding hills of southern Indiana. You can read about how it handled a full day of thrashing here, but this story will focus on the dead infotainment system previewed in the headline. About halfway through the twisty route, every sizable pothole or big bump in the road would cause the infotainment system to black out. A message would appear declaring “MOST NET LOSS,” and it would quickly dip to black after that. The next big pothole would cause it to flicker back on, but it never remained on for any long periods of time after this. In addition to the screen loss, the speakers would make some rather disturbing crackling noises. This continued throughout the day and for several days beyond that. If the roads I was driving on were flat or devoid of major problems, the infotainment system would generally be fine. It took a major jostling of the carÂ’s bones to cause it to act up, but Michigan provided enough of those to make the problem exceedingly annoying in a hurry. So, to the dealership it went. 2021 Acura TLX A-Spec View 51 Photos After the local dealer looked it over, they said there was a TSB out for this issue, and that theyÂ’ve seen it pop up on other RDXs and TLXs already. Turns out, there are a number of wire connectors between the infotainment system and wiring harness that are causing the problems and coming loose. The fix? Newly designed connectors from Acura, plus the wiring harness is ever so slightly freed up to allow for a bit of movement from violent impacts. Doing this (plus using the stronger new connectors) should ensure that the stress on these connectors is never so great as to cause issues again.  The job was completed under warranty and took a full day from diagnosis to the return of the car. WeÂ’ve put several hundred miles on the car since the fix, and theyÂ’ve been completely trouble-free — it sure was nice to listen to AcuraÂ’s excellent ELS audio system again. That said, this issue is one weÂ’ll follow closely to see if AcuraÂ’s fix truly is a long-term solution. WeÂ’ll have a deeper dive on how AcuraÂ’s TouchPad infotainment system works (now that itÂ’s actually working again) soon, so watch out for that update in the near future. You will be able to find all other posts on our Long-Term 2021 Acura TLX page.  Related:

Honda and Acura electric crossovers will be built by General Motors

General Motors will partially offset the cost of developing electric technology by manufacturing battery-powered cars for Honda and Acura, according to an unverified report. Ultium battery technology is at the center of the deal. Without citing sources, industry trade journal Automotive News wrote that Honda has agreed to enlist rival-turned-partner General Motors as one of its EV suppliers during the first half of the 2020s. The factory that currently builds Chevrolet's Blazer and Equinox in Ramos Arizpe, Mexico, will begin manufacturing a Honda crossover in 2023, meaning it likely won't arrive until the 2024 model year. On the other side of the border, the former Saturn plant in Spring Hill, Tennessee, will churn out an Acura crossover beginning in 2024, about two years after it starts making the Cadillac Lyriq. Neither model has been revealed, and Honda hasn't commented on the report. Insiders familiar with the contents of the firm's product pipeline told Automotive News that both crossovers will be about as big as the Lyriq (pictured), which will be close in size to the 190-inch long XT5. Power for the two models will come from the Ultium battery technology that General Motors is developing for over a dozen electric cars, including the GMC Hummer and a Chevrolet-badged pickup we might discover next week during CES 2021. Both EVs will be built by General Motors, and they'll be powered by General Motors-developed technology (some will even receive OnStar and the hands-free Super Cruise driver assistance system), but everything motorists see and touch will be Honda- or Acura-specific. We're not expecting that the tie-up will spawn a pair of blandly badge-engineered crossovers; stylists will likely give each one its own design identity inside and out. Honda had previously confirmed plans to build at least two electric models on General Motors bones, and it announced that its American partner would also handle manufacturing, but this is the first time executives are throwing Acura onto the stage. What remains to be seen — assuming the report is accurate — is whether the Lyriq will compete directly against its Acura-branded sister model, or if they'll be positioned in different segments.
