Hi,

1. Yes this is still available. I can email you a fully functional version for a one time $15 (US Dollars) registration fee. Once registered, you can receive free upgrades. The easiest way to send me the registration fee is via PayPal. Just use my email address (tomzeect@netscape.net) as the payment address.
2. The program has been tested on Windows 98, 2000 and XP. Not sure about Windows 7.
3. It will work on stock or modified engines. But, modified engines may need to run the target A/F ratio richer than stock.
Regards,

Tom


That's because it fires all 8 at once. some are just firing at the wrong time necessitating the need for more fuel.
This is old technology.

Your comment is correct when discussing port injection. However my comment was based on experience with throttle body injection. Specifically, non-stock cams seem to prefer richer A/F ratios.

Regards,

Tom

uhhh yah, on both TBI and multiport. I don't get your point. Seems you're talking in circles, they're essentially the same, they'll both require a richer mixture, TBI or MP.

I think some of the confusion is two separate issues are being discussed in this single thread. The first is the timing of the Holley pulses. The previous writer is correct about it being sub-optimal. The second issue has to do with engine efficiency. In addition to my own experience I've heard from drivers that successfully tuned their stock engines to operate well with a A/F ratio of 14.7. They later upgraded their cam and/or added boost, and discovered 14.7 was too lean.

Hi Krstian,

I have received your registration payment via PayPal, and have emailed you the program.

Tom,

I am very interested in the program that your have devised. So how much is the cost? I'm sort of a country motor head but I have a nice car 86 Monte Carlo that I have put a 400 small block in with aluim heads and performance cam along with changing it over EFI. The car runs but I'm not versed enough to tune it with the amount of time and knowledge Holley wants me to have in a short time. If your program is able to tune the Commander 950. Here's my email: dlm8454@yahoo.com Tell me what you need from me. Smile

Thanks,
Lee

Tom-

I sent you a PM last week. Has this been tested on Windows 7 yet? Also maybe someone can answer the question of whether the Commander 950 software can be run on Windows 7? Thanks.

Hi David,

I did reply to your private email. Not sure what happened, but the answer is yes, I've recently tested this program and it works on Windows OS 7.

Regards,

Tom

Tom, does the factory Holley software need to be installed on my laptop for your software to auto tune my ECU?

Hi David,

No it's not required. But it is helpful if only to save copies of all your setup parameters in *.950 file.

Regards,

Tom

Tom...I bought your program but have not ran it yet. I have read the instructions several times. When I drive the car while it collects and adjusts the data in each cell do I save the file with a Holley extension then send it to the ecu? Or do the changes it makes real time affect the performance of the car while you are driving? I am just trying to learn what to expect the first time I take it on the road.

Hi Brent,

The changes to the fuel map are sent to the ECU as you drive, and the ECU saves them in it's flash memory. So you're not required to save any files. However I do recommend you save all the set up parameters (which includes the fuel map) to a *.950 file once the vehicle is tuned to your satisfaction.

Regards,

Tom

Thanks Tom...how do I know when the program has completed its mapping or calibration? Is there a minimum number of miles to drive? Can I assume while I am driving and its updating I will notice the car (engine) running smoother or performing better?

Hi Brent,

On the fuel map display:
- cells running too rich will appear red
- cells running too lean will appear yellow
- cells running normally will appear green

Often when first starting out, the map will be a mixture of all colors, and gradually change to all green after 10- 50 miles.

Regards,

Tom

Can't wait to try it...how does the program know what is too rich and too lean? Does it default to a 14:1 ratio or something and try to achieve that? I think in the Holley program you can set a target ratio. Maybe I missed that in yours????

Hi Brent,

If you've installed a wide-band oxygen sensor, then:
1. Use the Holley program to set the target A/F ratios, and save them to the ECU.
2. Shut down the Holley program and start EFI_Tuning.exe
3. My program will read the new target A/F ratios from the ECU.

Regards,

Tom
