Mace Engineering offers Gen III LS1 custom bench-top reprogramming for your factory ECU using established tuning software. Our high standard for customer service guarantees you'll love the performance gains at prices you won't turn pale at.

Extracting performance and economy from the manufacturer's original engine management computer has become a popular modification in today's modification scene.

We have an extensive range of tunes in our database covering a large variety of modifications, which target all Holden vehicles factory fitted with the GEN III LS1 5.7L V8 engines. This allows us to select an appropriate and safe tune to suit your modification, whether it be a cold air intake, full exhaust system or diff gears etc. Power output will vary based on your vehicle's modifications, but the average LS1 with an intake and an exhaust upgrade will generally make around 220-230 rwkw with a substantial improvement in fuel economy.

In addition to editing the engine calibration, we can also improve the performance of the automatic transmission by accommodating a change in final drive ratio or stall converter, harden up the gear shifts and reduce shift times between gear changes. The choice is yours as we can tailor the tune to suit your needs.

 

Key Benefits:

  • Value for money when compared to a dyno tune.
  • Sharper throttle response.
  • Increased HP and torque.
  • Firmer gear changes.
  • Quicker gear changes.
  • Improved fuel economy.
  • MAF-Less tunes available.

 

Contents:

  • 1 X Performance enhanced engine calibration

Notes:

  • Please fill out our *tune form* and email it back to us following your purchase. There is a "fill and sign" feature under the tools section on adobe to make this process simple and easy. Alternatively, you can just email all the answer back to us.
  • We only do these ECU's on a change-over basis due to the limited number we can source, so the customer must send their PCM first with a completed tune form.
  • Our remote tunes can only currently cater for minor bolt-on modifications. Upgrades such as larger injectors, camshaft, modified heads and forced induction will require a dyno tune.

Nice shirt, great price.
Fit Type: Regular Fit, Color: White, Size: Medium
Worn it twice and I find it very comfortable. I wear it outside and casually to protect my arms and neck from the sun and find it more comfortable than a long sleeve t-shirt. The price is comparable. If I was to wear it to the office it would have to be ironed. I bought one shirt to try it and I will be buying more.

Nice shirt!
Fit Type: Regular Fit, Color: White, Size: X-Large
I added one of these shirts to another order just to see if they were any good. I was pleasantly surprised by the quality. It fits perfectly and looks pretty nice for a low cost casual dress shirt. Materials seem decent quality. Comfortable, soft fabric. Didn’t shrink too much in the washer and dryer. We’ll see how it holds up long term but so far so good
