Available for Basic & Power Tunes

This is the most common way for me to tune your PCM.

For 1994+ flash-based PCMs, you remove your PCM from your vehicle and mail it to me. I tune it to your specs, and mail it back to you; this obviously requires some down-time as the PCM is in transit both to and from you and me, and while I am tuning it while it's with me (usually a week from you sending it until you receive it back).

For 1993 and earlier chip-based PCMs, you order yourself an apppropriate piggyback adapter if desired to make installation easier, and I send you a new tuned chip to install in your PCM. You do not need to send me your PCM for those years.

I am willing to ship around the world, so even if you live overseas, we can still get it done!

This is an easier but less common way for me to tune your PCM.

It requires you to purchase your own ALDL cable and tuning software, and download/purchase datalogging software, in order to let me tune for you through email.

You begin with the base tuned file I will send which will be set to your setup's specs, and then with datalogging software you will record the car while it's running. I then use those logs to fine-tune the PCM and give you updated tunes to use. Three such free retunes are included with the order, and additional retunes past the first three are only $ for each additional three.

This saves you down-time since you do not need to send me your 1994+ PCM, and allows the tune to more accurately maatch your specific setup.

This is the new way for me to tune your PCM! It comes with step-by-step instructions too!

For 1994-2005 flash-based LT1/LS1 PCMs, you rent an ALDL cable and free software from me, which you can use to load my tune into your own PCM without needing to remove it, as well as data-log while driving, so I can fine-tune the PCM exactly to how your car is running. You will have 1 week of fine-tuning available from me starting when you receive my first tune; each additional week costs $35 ('94-'95 LT1) / $45 ('96-'97 LT1) / $50 ('97-'05 Vortec/LS1).

For 1986-1993 TBI/TPI/LT1 chip-based PCMs, I send you a chip burner/eraser, a blank chip, a memcal reader (for you to read your stock chip's image for me to use as the base for your new tune), and an ALDL cable. Once you read your memcal, I build your new tune to your specs and email it to you, at which point you then burn it onto the blank chip I send. Then, you can use the cable to datalog the vehicle running with it so that I can fine-tune things and email you updated tunes that you can burn onto the same chip (it is eraseable). You will have 1 week of fine-tuning available from me starting when you receive my first new tune; each additional week costs $45. You will need an adapter from Moates to easily install the new chips (G1 for TPI/LT1, G2 for TBI).

This saves you down-time just like the Email option. If you don't see the need for having your own tuning kit, this saves you some money over buying your own hardware/software, but still allows me to fine-tune your PCM according to how your actual vehicle is running.

When you order, you will pay the tune price as well as a refundable core charge for the kit. Once we are finished tuning, and I receive the kit back from you, your full core charge will be refunded to your PayPal account/credit card, so you will end up paying only the tune price. If you keep the kit one week more than the rental time for which you paid, or you decide you'd like to keep it for yourself, I will consider it a purchase and your core charge will not be refunded.

Requirements:

• Laptop/Netbook - needed to flash 1994-2005 LT1/LS1 PCMs, and data-log 1986-2005 vehicles while driving
• USB port - needed for connecting the ALDL cable to your laptop
• Comfortability using computers and programs - if you are a complete computer novice, this will not be for you; if you can install and use normal computer programs and install a USB device, you should be fine!
• ALDL vehicle port - all factory vehicles which I can tune come with these; it is necessary to data-log the vehicle while driving, as well as to load the tunes for 1994-2005 flash-based LT1/LS1 PCMs.
• Windows 98/2000/XP/Vista/7 - needed to run the tuning/data-logging software and to support the USB cable driver
• CDROM Drive (OBDI/OBDII) or Internet connection (OBDI) - a CD is mailed with the necessary software; otherwise, for OBDI ('86-'95), you can download it from the Internet

There is also one slight risk with this method for the '94-'05 LT1/LS1 PCMs: if anything interrupts the PCM programming/flashing process, which you will be doing with your own PCM and my cable, it will damage the PCM and require repair before running again. So, you will need to accept this risk and ensure that your laptop and vehicle batteries are fully charged or plugged in to AC and that nothing interrupts it.

But, the benefits far outweigh this small risk! You can get your vehicle running amazingly well without ever sending me your PCM!

Basic Tuning is for those who only need non-power items changed, which are quick fixes, like rear gear ratio and/or tire size (for '94-'97), removal of VATS/AIR Pump/EGR/skip-shift, or changing to speed density. It is only available through the Postal tuning method.

This option is also good for those who are doing an engine swap, putting the LT1 into another car, and don't desire any extra power gains over stock.

See below for more items that can be changed. If you need any spark timing changes, fueling changes, or automatic transmission changes, you will need the Power Tune.

$100 (Chip) / $110 (OBDI) / $120 (OBDII) / $150 (LS1) Shipped
$70 (OBDI/Chip) / $85 (OBDII) / $100 (LS1) Emailed

Power Tuning includes any changes available in Basic, as well as changes for increasing torque and horsepower, increasing MPG, or automatic shifting changes, such as firmness, shift points, and TCC lockup points.

This works even on stock engines, as one customer with a stock engine in his '94 Z28, gained 26 rwhp with just my tuning!

If you have your own programming hardware and software, but want a base tune to build upon or even want the tune completely done for you, then my Power Tune can be sent to you via Email, and includes three free retunes.

What setups need Power Tuning?

• Significant engine modifications, such as new cams, heads, overbore/stroke, or compression ratio changes
• Swapping stock LT1 heads, either iron to aluminum, or vice-versa

If you order my Power Tune via Email or Cable Loan, then you will benefit from using FreeScan or DataMaster logs of your own vehicle running with my tune, to allow me to fine-tune your PCM even further.

This is real-world, street-feedback, which will get your car running like how you want! It also will increase MPG, throttle response, and overall power.

What are other benefits of Power Tuning?

• Improved drivability and likely even MPG, just from timing changes.
• Noticeable MPG increase if you select a version of my MPG Improvement
• Auto transmission shift points matched to your engine's "sweet spot" of torque and power
• Locking the TCC earlier and/or at WOT to increase power to the rear-wheels

What is MPG Improvement? If you read my "Tips" page, you will see exactly how it is done. To summarize, in open loop I simply program the PCM to run a leaner AFR (air:fuel mixture) from your base settings. In closed loop, when the oxygen sensors are functioning, I tell the PCM to use a lower voltage as the ideal point in order to make it run leaner. Both will use less fuel, which will improve MPG.

One customer with a stock '94 L99 engine (4.3L V8, so-called "baby LT1") reported over 30 MPG highway in a full-size Caprice when using only the Moderate version of my MPG Improvement!

Another customer with a stock '97 LT1 said that he went from 14-15 to 19 MPG with my Moderate MPG Improvement, even with his aggressive driving! A gain of 4-5MPG with just tuning!

Below is a partial list of the various systems and their checks that I can enable/disable for you. Many of these are not needed when you swap the LT1 engine and PCM into other vehicles, like hot rods or foreign cars.

• VATS (Vehicle Anti-Theft Sensor)
• CAGS/CARS (Skip-shift for M6 transmissions)
• AIR Pump
• EGR
• CCP (carbon canister purge)
• VSS (Vehicle Speed Sensor)
• A/C (for removal of air conditioning system)
• Traction Control - for those that never use it, this will permanently disable it
• MAF Sensor - causes the car to run in Speed Density mode, which uses the VE tables, along with the MAP and IAT sensors
• O2 Sensors - causes car to permanently run in "open loop," which requires careful tuning since no fueling correction is done
• And much, much more - contact me with any questions!

Did you recently do some of the mods below? They can easily be accomodated with the Basic Tune:

• Fan Settings - added a 160° thermostat? Now make your fans come on sooner to help cool your engine better!
• Rear Gears or Wheels/Tires - so your speedometer and automatic shifting work correctly again!
• Fuel Injectors - so your car doesn't run lean or rich any more
• Ported, F-Body, ZO6 MAF Sensor - did you port and/or descreen your stock MAF sensor (you shouldn't have!)? Switch from B-Body MAF to F-Body? It changed how your engine runs and the PCM needs updated to restore your full drivability, MPG and power. Some drivability can be restored with ported stock MAFs, but you should always run with the screen installed. The ZO6 MAF is a cheaper replacement for broken LT1 MAFs, and is larger for more airflow, but is hard-coded to have a lower flow limit than the stock MAF.

I accept PayPal for all order types. PayPal is a secure, online payment system, which allows you to securely send me payment with your checking/savings account, credit card, eCheck, or if you already have an account, your PayPal balance.

You do not need to create a PayPal account to send payment with a credit card, as you will still be able to use their secure processing to use your credit card without needing to create an account.

I accept a cashier's check or money order for for Postal and Email tunes only (not Cable Loan). Please, no personal checks, as they can take several days to a week to clear, which will hold up your tuning order.

Turn-Around Time

Once you place an order, and I receive your PCM (or email image) and payment, I will begin work right away. In many cases, I will be able to have your tune ready in one or two business days, either for shipment back to you or emailed. But, sometimes it can take up to three to four business days, depending on my current schedule.

I also offer expedited/overnight return-shipping if you are in a hurry!

Free Retunes

Tuning not done in person will never match in-person tuning, whether done in the car or on a dyno. For this reason, I offer free retunes for those who have ordered from me in order to get it "right" for you.

For those ordering via postal mail, I offer one free retune if you pay for shipping both ways.

For those ordering via email, I offer up to three free retunes, optionally (and ideally) using your own DataMaster, FreeScan or TunerPro RT logs to fine-tune the PCM.

For those ordering via cable loan, you will have one week to datalog your vehicle using my included software, and let me fine-tune it based on those logs and your feedback.

To request a PCM to be tuned, I ask that you first sign up as a customer. This allows me to keep each person's name and mailing information separate from their PCM info, in case they ever send another PCM or have the same one retuned in the future.

Once signed up, you will be issued a customer number, which, along with your chosen password, you can then use for the PCM tune order form. This way each order is able to be tracked much more efficiently, saving both you and me time. Thanks in advance for your cooperation!
