Electronics - ZZP ATS/CTS/Camaro PCM Tune

The ZZP 2.0 liter turbo PCM brings the performance of your car to a whole new level.  We go through and rework dozens of tables based on countless dyno tuning with our own vehicles.  We own 5 ATS' enabling us to dial in our LTG tuning better than any other company in this market.

  • Fuel cutoff rpm limit increased
  • Variable valve timing optimized for better response and more power
  • Power enrichment tables adjusted for a more consistent air fuel ratio
  • Spark timing optimized for premium fuel
  • Driver demand and torque tables adjusted for greater performance
  • Turbocharger settings adjusted for more boost
  • Fuel injection timing adjusted for higher airloads
  • Fuel pressure raised at high loads
  • Coolant thermostat settings adjusted for cooler engine temps
  • Fan settings lowered for cooler engine temps
  • PE engagement time is reduced
  • 40HP gain over stock file on Premium fuel
  • Does not alter emissions
  • Enable active Flex Fuel in PCM for our ATS E85 Flex Fuel Conversion Kit. SEE BELOW NOTE.

The fastest stock turbo ATS in the world runs our tune (12.0).

How to order your tune:

Car Year: Please type the year of your car. CTS & '16+ ATS costs extra due to the extra credits required to license the tune.

Fuel Type: Please select the appropriate fuel/octane you will be running.  Any factory boosted car should be running at least premium fuel.

ZZP Flex Fuel Conversion Kit: Please select yes or no.  If you want to run our Flex Fuel Conversion Kit, please purchase it along with the PCM tune.  Do not select Yes unless it is being installed unless you will throw a code.  *When this is enabled in the PCM, the kit must be installed and functioning before the car is driven or it will cause damage to the engine.  NOTE: Flex fuel is available for all model year LTG's as of February 2020. 

Core Charge: There are a couple options here...  #1 We can ship you a new PCM core that is already flashed with our file.  The benefit of this, is that you can keep your stock PCM to reinstall if you need to bring your car in for warranty work.  The disadvantages are a: that if you have remote start, it will disable it. (This applies to 13-17 ATS, CTS, and Camaro only) and b: if you have a '16+ manual trans car, you will have to go to the dealer and get a clutch relearn.  #2 We can send you a programming interface and cable which we supply with instructions.  It will allow you to read your stock file, email it to us for modification, we email you back a modified tune, you upload it to your ECU, and send us a scan, then if additional tweaks are needed, we can modify the file again to perfect it.  When tuning is done, you can return the interface/laptop, and you are refunded the interface/laptop core charge (deposit).  Since you are keeping your stock PCM core, this will retain your remote start feature.  If you do not rent our laptop, you will need a Windows based laptop to read/write your ECU.  The advantage of using ours is that it comes pre-configured with the tuning and scanning software required so you can simply charge the laptop, power it up and get started immediately.  We can assist you if you have any questions or custom tuning requirements.  If you choose to keep the tuning interface and/or the laptop, that's fine, we just wont refund the core charge.  Core charges are based on 14 days and there will be additional charges if cables or laptops are kept for longer periods.  After 30 days, core charges convert to purchases.  If you would like to watch a video to see how remote tunes work. Click here

Special Notes:

Once PCMs are purchased, they are not refundable, HP Tuners credits are used, cores are married to specific vin#s, that means once you click the final payment buttons on your order, it cannot be refunded.

'17+ Automatic transmission cars must remove their TCM and ship it to HPTuners to be unlocked so it can be tuned by us.  This has an additional cost of $200. We also have new unlocked TCM's available here.

Custom LTG Swaps: This option is for anyone looking to tune a vehicle that did not come with an LTG originally. You MUST choose this option if you are tuning a tube chassis car, sand rail, LTG engine retro fit into an older chassis, etc. Do not try to cheap out and purchase a tune from another year/make/model, we will find out and will not continue the tuning process if so. Be aware that when you purchase and start the remote tuning process you are purchasing our tuning services, not diagnostic services. The tune will be put together assuming you have all necessary sensors, boost lines, vacuum lines, etc hooked up correctly. Once you and the tuner have verified that the car is running well and you're both happy with the tune you have 7 days to request any changes. Once that 7 days has run up you can re-purchase our tuning services for your custom swap for $200. 

Note: Prepaid return labels for interface/laptop rentals are only included with domestic shipments.

When choosing sending in core first option you will want to ship your PCM to

The tune is worth it

I used the remote tune option so i loaded the files and did the scanns myself, the directions were solid and not hard to follow. Tune files came back quickly from the tuner, once i submitted my scan files. If you're just stock or a few modes i believe getting a tune from zzp is was well worth it, with each new file you could really feel the difference in the vehicles Performance. Sport mode really feels like sport mode This was worth every penny....

Great product

So, I purchased this to see if I could get more performance outta the mods I had already purchased. From stock to ZZP CAI, larger throttle body, ZZP Catted downpipe, E-85 sensor, and PCM has turned this car into a completely different animal. Did my first oil change, super clean. Fuel efficiency on E-85 is awful, but the performance vs 91/93 is extremely noticeable. The best thing is that regular driveability aside from fuel mileage is almost not noticeable. It’s only when you put your foot down that you can really see the immense difference. Highly recommended and extremely happy.

The difference is very noticeable from stock tune. Matt wasted no time adjusting and sending the files back. Currently have the ZZP cold air intake, downpipe (gutted it out) and oil catch can. Looking forward to eventually adding flex fuel, big wheel turbo, cac and throttle body!

Impressive HP gains and actually safer than OEM tune

Turbo Tim is great. Very informative and knows the LTG 2.0 very well. He tuned my ATS with plenty of power and was able to Keep it safer than the OEM tune. I asked him questions about next steps for more HP and gave me his feed back without delay. The amazing thing about the service was Tim was emailing me tunes on Sunday. E85 conversion, CAI, ZZP high flow down Pipe, Larger TB and ZZP charge pipes,Remote tune. I’ll be back for Cams, Valve springs and an upgraded turbo.
