What can an INTENSE ECM do for you?
For over five years
INTENSE has brought PCM/ECM Tuning to the late model GM FWD community. Now
INTENSE offers our experience and tuning expertise to the Pontiac G8 community. Our
INTENSE G8 ECM tunes are based on our knowledge gained from working on our
INTENSE G8 Project Car which is evolving into a world-class super car. Air/Fuel adjustments along with ignition timing tweaks and the reduction of excessive torque management produce a realistic and repeatable 20-22 rwhp on 6.0L G8's using 93/94 octane*. Fan point changes in conjunction with a cooler thermostat help the cooling system keep the extra heat in check and we also enable the cooling fans to run at key-off
under certain conditions. INTENSE tunes produce the hardest launching G8's and while you won’t see these changes on the dyno, you’ll definitely feel them the first time you leave hard from a stop. Instead of the relatively benign power produced off idle by your stock ECM, our optimized tune will plant you hard in your seat and give your tires a workout.

Every INTENSE ECM is coded with the correct year, make and model of your vehicle and is completely undetectable by a dealer.
Each ECM starts with the latest operating system available from GM for your VIN. This means if there is an operating system upgrade available for your vehicle you will automatically receive it and then we apply our changes on top of that. We use GM Service Programming System (SPS) for this service and receive monthly updates. See http://calid.gm.com for details.
We have complete access to thousands of parameters within every ECM. For example we can disable individual DTC's based on a customer's specific needs.
INTENSE ECM's are processed and shipped with the same top notch service INTENSE has been known to provide. Most ECM's will ship within one business day of your order!

Frequently Asked Questions (FAQ)
How hard is the G8 ECM to install?
Installation of the INTENSE ECM is simple and straightforward. Please view the
Pontiac G8 ECM Installation Instructions for a step by step guide.
What do I need to do after installing a new INTENSE ECM?
If you physically replace the ECM with a different ECM than your stock one you will probably have to perform a
Security Learn. All cars will benefit from a
Crankshaft Position Variation Learn procedure (commonly referred to as CASE Learn). Anyone with a Tech II (such as a GM dealership) can perform this special function for you in a couple minutes. Some discretion is necessary when asking your dealership to NOT re-flash the ECM. If they re-flash the ECM, all your special tuning will be gone and un-retrievable. Many dealers will perform the Crankshaft Position Variation Learn procedure for free, while others may charge a modest fee.
What hardware and software does INTENSE use to do ECMs ?
We use a combination of GM SPS, EASE, TIS and HP Tuners Professional hardware and software. We do not lock our programming and this allows you to use software such as HP Tuners to modify your code in the future.
How does your ECM compare to other brands?
Notice in our
before and after tune that the "after" air/fuel is almost textbook. WOT ignition timing is also optimized.
Some tuners only change a couple of settings. Here at INTENSE, we know GM tuning inside and out. Here is a partial list of the tables we change in our base G8 tunes. Some of these tables contain dozens of fields, so our typical G8 tune will have approximately 200 changes.
Target idle speed table (for park, neutral and in gear)
MAF calibration table (airflow versus frequency)
Power enrichment table (equivalency ratio versus engine speed)
Main spark advance table (high octane)
Base upshift time tables (special mode)
Upshift time inertia adder tables (special mode)
Downshift time inertia adder tables (special mode)
Cooling fan run time (at key-off)
Engine coolant temperature zone tables (for fan modes)
Fan desired tables (percentage versus ECT)
Speed limiters (all set to 255 mph)
Do you lock your ECMs?
No. Unlike our some of our competitors we do not lock our programming which can cause problems down the road if you want to make changes or purchase an editor like HP Tuners. If you have HP Tuners or any other programmer you will be able to read, modify and write to your ECM at any point, for any reason.
Will your ECM affect my fuel economy?
Not directly, no. If you enjoy the performance gains, you're likely to drive the car harder, and this will reduce your fuel economy. But we don't change any light throttle parameters at all.
Why don't you make light throttle changes for fuel economy improvements?
We do not believe that we are smarter than G.M. powertrain engineers in this area.
Why are your ECMs so much less expensive (43% in some cases!) than some other brands?
INTENSE has been a dyno tuning and mail order ECM leader for many years. We have ECM core vendors and channel partners already in place that allow us to offer products at a lower price than other startup companies.
What is a core charge?
A core charge allows you to purchase a computer from us first. We then reprogram this computer and send it to you. Once you return your original computer to we refund your core charge in full. This allows you to continue to drive your vehicle while you wait for the INTENSE ECM to be shipped to you. If you choose not to send in your original computer that is completely fine however you would not receive your core charge back.
Why are your core charges less expensive (67% in some cases!) than some other companies?
INTENSE has been a dyno tuning and mail order ECM leader for many years. We have ECM core vendors and channel partners already in place that allow us to offer cores at a lower price than other startup companies.
Do your G8 ECMs include TCM (transmission) changes also?
If you come to INTENSE for a ECM flash or custom dyno tune, then these changes are also included. If you order a mail order ECM, then only the engine calibrations are made.
What if I don't like your INTENSE ECM for any reason?
Just send it back to us within seven days for a full refund.
*While optimized for 93/94 octane, our tunes will work fine with octane as low as 87 although performance will suffer.
