• IE POWERlink is a tuning tool: a Bluetooth cable for the OBD-II port and an app that tune the car, switch octanes, upgrade stages, read codes, show live gauges and log data, according to IE's POWERlink Mobile page, checked on 22 October 2026.
• On CarPlay, POWERlink controls an iE tune: IE's Full Throttle page, checked on 22 October 2026, lists adjusting LIVE feature settings, customising gauges, clearing codes, running diagnostics and valet mode from the car's screen, plus Siri voice commands for tune settings.
• WrenchTime is a live-data and log app for any car: it reads standard OBD-II data through a Bluetooth LE ELM327 adapter or an OBDLink MX+, draws it as a gauge grid on CarPlay with WrenchTime Pro, records it with every trip and keeps the car's maintenance and fuel log. It does not flash or change the engine computer's programming: besides reading, it can only clear trouble codes (Pro).

What is IE POWERlink, and does it have an app?

Yes. IE POWERlink is Integrated Engineering's tuning tool: the POWERlink V4 cable plugs into the car's OBD-II port and pairs over Bluetooth with the POWERlink app on an Apple or Android phone, or connects to a Windows laptop running IE's Flash Wizard software. IE's POWERlink Mobile page, checked on 22 October 2026, says the cable and app let you tune the car, change octanes, upgrade stages, read and clear codes, check emissions monitors, watch live gauges and record datalogs.

On the US App Store the app is called POWERlink Suite: free, published by Integrated Engineering, for iPhone and iPad on iOS 17.0 or later, rated 4.8 from 1.6K ratings, with a privacy label that reads Data Not Collected, all checked on 22 October 2026. The listing states that it requires a POWERlink V4 dongle and tuning software from iE or Xodus.

IE's POWERlink V4 product page lists the cable at $184.99, checked on 22 October 2026, and says "Tuner only. Tunes sold separately." One cable can flash up to five vehicle VINs. The mobile app does not work with the older V3 cable, and IE offers a $50 refund on a V4 when a V3 is returned. Some older VW and Audi 2.0T and 2.5L cars are tuned from the laptop instead of the app.

Which cars POWERlink can flash from a phone is on IE's mobile flashing compatibility guide, summarised below. IE says other platforms are available through the Windows laptop and Flash Wizard.

What does Integrated Engineering's CarPlay app do?

Integrated Engineering's CarPlay app puts the POWERlink app on the car's screen. IE announced it with its Full Throttle, Fall 2026 release, and the retailer UroTuning reported it on 21 October 2026. IE's Full Throttle page, checked on 22 October 2026, describes it as "New for every tune with adjustable features": the LIVE adjustable features IE launched in April for the phone can now be changed on the CarPlay screen, or by asking Siri.

The POWERlink Suite release notes for version 4.0.0, published 21 October 2026, describe a CarPlay app that reads and erases codes, checks readiness monitors, controls adjustable features, shows live gauges and logs data, plus CarPlay widgets that change Tune Adjustments from the head unit. IE notes that the widgets work on "Touchscreen units only" and are "Not compatible with Audi MMI". The features IE lists, checked on 22 October 2026:

• LIVE adjustable features on the car's screen: adjust LIVE feature settings, customise gauges, clear codes, run diagnostics and enter valet mode from CarPlay, in IE's words "the full POWERlink app on your car's screen".
• Widgets as a performance dashboard: the features used most can be placed on the CarPlay display, which IE describes as a performance dashboard showing readings such as intake temperatures and ethanol percentage.
• Siri: voice commands change tune settings; the demo on IE's page suggests "Set my exhaust to aggressive", and the release notes say "Hey Siri, help with POWERlink suite" lists the available commands.
• Garage: the car's photo, tune, suite, hardware and LIVE settings stored in the app and shareable, with custom settings saved for different driving conditions.

Which cars does IE's CarPlay support?

IE's CarPlay tune controls follow its tunes with LIVE adjustable features: the Full Throttle page, checked on 22 October 2026, presents CarPlay as "New for every tune with adjustable features", the LIVE adjustable features IE launched in April for the phone. The same page tags CarPlay on three platform groups, listed below: the Audi S4 and its sibling models with the 3.0T and 2.9T engines, the MK7 Golf GTI, GLI and Golf R with the Audi S3, and the MK8 Golf GTI and Golf R with the Audi S3.

IE's Full Throttle page and its MK7 page, both checked on 22 October 2026, tell owners already running adjustable features: "You already have this. Just update the POWERlink app." The mobile flashing list in the previous section is a different list: it says which cars the app can flash, not which tunes have CarPlay controls.

IE POWERlink vs WrenchTime at a glance

The table compares the two on what each maker states, with IE's side checked on 22 October 2026 against its Full Throttle page, the POWERlink V4 page and the POWERlink Suite App Store listing. "Not listed" means those IE pages do not mention the feature, not that it is confirmed to be missing. Which adapters WrenchTime works with is on the OBD-II adapters for iPhone page.

How does WrenchTime show gauges on CarPlay?

Of the apps on this page, WrenchTime is the one whose CarPlay gauges work on any car that answers standard OBD-II, with no tune and no proprietary cable. POWERlink's listing requires its V4 dongle and an iE or Xodus tune, OBD Fusion's CarPlay screen is a list, and Car Scanner's page does not mention CarPlay (checked 27 October 2026).

It is also the one with a CarPlay tab of fuel stations or chargers nearby, and the one that keeps a maintenance, fuel and trip log. POWERlink's Garage holds tuning datalogs, and the other two pages mention neither.

WrenchTime is an iPhone app for car and motorcycle maintenance, fuel, trips and live OBD-II data. With a Bluetooth LE ELM327 adapter or the Apple-certified OBDLink MX+ and WrenchTime Pro, its CarPlay Live tab is a grid of gauges you lay out per vehicle, read from any car that answers standard OBD-II. Standard OBD-II is the generic engine data a car reports to any compatible adapter, which is why no tune and no make-specific tool is needed.

Each tile is a ring with caution and critical bands, a short graph of recent values or a plain number, and a row holds three to eight tiles. The tachometer and the speedometer read the car's own computer, not GPS, and boost, coolant temperature, throttle, voltage, fuel level, fuel rate, any other standard reading the car reports or a custom PID can be a tile. The grid is redrawn twice a second by default.

A reading that enters its critical band raises one alert on the car's screen, and tapping a tile shows its minimum, maximum and average for the drive. Three more tabs record and tag trips, find fuel stations or chargers nearby, and show what is due on the car. The OBD2 app for CarPlay guide covers the layout and the alerts, and how CarPlay gauges work across apps compares what other apps show.

Beyond the car's screen, the same adapter feeds the WrenchTime Live dashboard on the phone, 18 instrument types on pages you build, and every reading can be recorded with the trip at one sample per second, to read back on the trip's timeline. While a trip records, its Live Activity sits on the Lock Screen, in the Dynamic Island and on the CarPlay Dashboard beside the map.

With WrenchTime Pro, Vehicle Tools reads stored, pending and permanent trouble codes with the readiness monitors and the freeze frame, and custom signals add readings the car reports beyond the standard set, imported from a catalogue and tested on your car before you rely on them. A custom signal becomes a CarPlay tile like any other.

WrenchTime is built natively in SwiftUI for iOS 26, using Liquid Glass and the Dynamic Island rather than imitating them. A trip runs as a Live Activity on the Lock Screen and in the Dynamic Island, 9 Home Screen and Lock Screen widgets, some with WrenchTime Pro, keep the log in view, and an Apple Watch app and a permanent iPad sidebar carry it further.

The dark theme is calibrated for OLED, the app takes any of 30 accent themes, and there are no ads on either tier, no account, and sync only through your own private iCloud. CarPlay, the Apple Watch app and the accent themes are part of WrenchTime Pro.

Can WrenchTime and IE POWERlink run on the same car?

Yes, as two separate tools for two separate jobs. WrenchTime reads standard OBD-II data through its own Bluetooth adapter and does not flash or change the engine computer's programming: besides reading, it can only clear trouble codes (Pro), with the engine off. It neither reads nor changes an iE tune's adjustable features. Tune changes, octane switches and flashing are done in IE's POWERlink app, on the phone or, as IE's Full Throttle page describes, on CarPlay.

Both devices plug into the car's OBD-II port, so the one in the port at the time is the one that has a link to the car. Coding a VW or Audi, as opposed to tuning it, is a job for a coding tool; OBDeleven vs WrenchTime says where a coding app and WrenchTime each stop.

Which one should you choose?

Pick by whether you want to change the car's tune or watch and record what the engine is doing. Each line is the need that app suits, WrenchTime included.

As the table above states, from IE's pages checked on 26 October 2026, POWERlink's CarPlay tune controls need an iE tune and its POWERlink V4 cable; WrenchTime's CarPlay gauges work on any car that answers standard OBD-II, with no tune and no proprietary cable.

• Choose IE POWERlink if you run, or plan to run, an iE tune on a platform IE supports and want what IE's Full Throttle page describes: LIVE adjustable features, gauges and code reading on the CarPlay screen, tune settings by Siri, and flashing and octane changes from the phone.
• Choose OBD Fusion if a text list of readings on CarPlay is enough and you want its phone dashboards, Mode 06 or paid packs per make, for $9.99.
• Choose WrenchTime if you want live OBD-II gauges on CarPlay on any car, tuned or not, recorded with every drive and kept next to the car's maintenance, fuel and trip log, with live data free on the phone, CarPlay with WrenchTime Pro and no account.
• Choose Car Scanner ELM OBD2 if you only need gauges on the phone, for free with Pro at $7.99 once, and no CarPlay screen.
• Use both if you tune with iE and also want a long-term record of the car: POWERlink for the tune, WrenchTime for the servicing, the fill-ups and the drives.
