Looking for modified BIN file to compare

[GMC Truck]

Smallblock with Vortec heads and TBI with headers using the bigblock TBI unit. Anybody running this combo? Id like to see the setup in the BIN file. I have been reading alot about fuel changes and spark tables and now it has me nervous about my setup.

I have stock .bin files for 7747 ECM ($42), and I have the modified .bin files for my $E6 93 GMC.

"FULL CUSTOM" Tunes w/ 1-year of tuning support
OBD-1 Chip / MEM-CAL............................................................$180.00

Explanation of a "Custom" tune...
In a "custom" tune, you tell us everything you have done to the vehicle and also anything specifically you want done to the computer programming. For example, you will need to tell us what emissions devices are have removed so we can determine what trouble codes you need disabled, what you want the idle set at, what you want the top speed and rev limiters set at, etc.. If you are using an aftermarket cam or have done extensive modifications to the engine, we will need to have a detailed list of everything you have done so we can make the proper custom changes to the programming.
You should also be aware that custom tuning can be a long and involved process that may not be 100% correct on the first try. It may take several tries to get the tuning right for your application. And the only way to get the tuning right is if you can supply us with scan tool and/or wideband O2 AFR data.

Support / Refund policy for custom tunes...
Customer must accept and agree to the following policy/terms for custom tunes...

• The customer must be aware (and agree) that custom tuning may involve a lengthy process where it may take several tries until a good tune is found. It is likely a perfect tune will not be attained on the first try.
• The customer is responsible for getting scan data and/or wideband O2 AFR data upon request so accurate changes can be made.
• The customer is responsible for all shipping, insurance, and other related costs.
• All support / refund policies are effective for only 1 year from the original purchase date.

If changes are required and you supply us with all requested information/data, we will reprogram your computer with the corrections at no extra cost to you for these services, but you will still be responsible for shipping costs. If you are not satisfied with our services, we will issue you a refund for the price of the tuning service once the following requirement is met...

• Computer/chip must be returned to us so we can put stock/original programming back on it. If you ordered a mem-cal adapter, that must also be returned to us in order for you to receive a refund for the purchase of that.

No refunds will be given after 1 year from the original purchase date. No refunds will be given for shipping, insurance, or other charges; customer is responsible for all of these costs. No refunds (except for special circumstances) will be issued for custom .bin files emailed to you since we cannot verify you've deleted the file(s) from your computer.

I can do alot of guessing for $180.00! I just wanted to see what needs to be changed when adding the Vortec heads. GM offers a manifold for the Vortec heads using the TBI system so they will work but are they close to the standard heads that if you "added" them to a stock TBI engine the ECM would learn the new airflow requirements?? Surfing the web sites there seems to be alot of people using the Vortec heads and many diffrent stories on what needs to be changed to use them. The truck i'm currently working on has a stock 5.7 with vortec heads and a GM aluminum "carb" manifold with long tube headers. I have added the TBI system with an adaptor plate using a 454 TBI unit. Its not up and running yet but from advice you (dave w) have given me here and on the FSC fourm I have made some changes to my system. I now have a heated o2 sensor and am making changes to the BIN file you put up at moates site for me (ANMW). I was just wondering about changes, if any for the vortec heads on this engine.

I think the GM Vortec / Carb intake with a TBI adapter will be just as good, maybe even better that a Vortec / TBI intake. I've only built one engine using Vortec heads, a SBC 400 about 8 years ago. The Vortec SBC 400 engine owner is using a carburetor. The SBC 400 Vortec engine runs very strong.

I posted the information from Sinister Performance for a couple reasons. They are likely to have more experience with the 7747 ECM than me, and it's likely Sinister Performance has a .bin file for the engine configuration you built? Sinister Performance offers a limited support performance .bin file for $55.00, (something to get started with). I wanted to share .bin options that might or might not have been know to you and other readers.

I think the Vortec heads, and headers will require the fuel tables to be set richer ( slightly larger numbers). Getting the BPW set is the first step, as I mentioned on FSC. The 454 injectors require a change to the BPW. Once the engine is running at idle, check the engine main vacuum with mechanical vacuum gauge. Try changing the BPW up / down to see where the "best" vacuum is. Then it's time to test drive and data record with WinALDL / TurnerPro RT to figure out which fuel tables are rich / lean.

The timing tables are not easy to figure out, so I make my best guess and live with the guess. If I see knock counts, I retard timing a couple degrees. Vortec heads usually increase compression, so I would keep the max timing to 34 ~ 36 degrees. Usually base timing is Zero or 4 degrees, so before changing a timing table, I retard / advance the base timing +2/-2 degrees and look for spark knocks.

I think you've done your homework, and it's time to take the final exam. There is no service manual, or detailed how to book on tuning a PROM. If you have more study questions, please ask. A failure on the final exam can be expensive.

Thats the info i'm lookin for and yes i've read a ton of stuff on the net about setting up and burning chips but nobody really goes into what does what and why. I got kicked off of the thirdgen site cause I have a truck I guess?? They would just totally ignore my questions or just offer links or one word answers... then I joined here and you and this site have been a great help! I'm new at burning chips and programming them but not new to EFI or engine building. The hardest part is just figuring out what changes to make to get the results you need. Some of the sfuff GM put into the BIN files seems redundant but I bet is there for a reason!

I have a 7747 performance chip, but it's from the Edelbrock (part number 3502) MPFI conversion kit. I'm thinking Edelbrock does not want me to post the .bin file on Moates.net?

The fuel tables are very different from a stock TBI! The timing tables should / could work for the Vortec engine? I don't see anything in the timing tables that would be a "don't use".

I use the search feature on Thridgen alot, I ask very few question on Thirdgen. When I do ask questions, I get very few if any responses.

Thanks for posting the images that will at least give me something to compare. I now have my truck up and running with the 454 tbi unit and it seems to run really well but I have not road tested it yet...? I set the BPW to 115 in the chip and left everything else "as was" except removing the EGR that I don't have. I have read that the vortec heads need more timing to perform best is there a way to increase the timing like 2 degrees across the whole board or will i have to change each little block? (tuner pro)

With TunerPro you can use the Table Editor, you might have to open the Table Editor from the Tool Box. Highlight all the cells in the table, just like an Excel file - a mouse move to click / drag the cells you want to select. Set the Table Editor:
Function Type for "Offset +/-"
Value for "2"
Then click "Execute"

All the cells selected will increase by 2. If you want to Subtract 2 degrees, change the "Value" to a Negative number of "-2".

I downloaded this file but what is it??

 

[GMC Truck]

I looked at your ANMW spark table in the above pic, is that modified?? Heres the one I have and I have not changed anything in the spark table. Compare mine to the one you posted, they are diffrent.......

I downloaded this file but what is it??

The Excel file is a data log file that was saved as an Excel file. With Excel the data can be organized by RPM, BLM's, MPH and Kpa or other data. Lets say your 2400 RPM / 40 Kpa cell has a BLM average of 134 (lean). So the Excel file can be used to organize and correct lean / rich cells.

I looked at your ANMW spark table in the above pic, is that modified?? Heres the one I have and I have not changed anything in the spark table. Compare mine to the one you posted, they are diffrent.......

Thanks for the screen shot, nice to see what differences are!
I down loaded the ANMW from Moates.net. There could be a few different ANMW files on Moates.net? Modified bins / 7747 bins / 7742 - 42 bins / folders. I don't remember which folder I down loaded the ANMW from.

I like the timing table on the ANMW table you posted, it's more a performance timing table. I have some timing cell with 40 degrees advance on my 93 GMC, but I have a 180 degree thermostat also.

So would that be a good starting timing table for my 350 with the vortec heads? I now have the truck running but it kept fouling the plugs on cylinders 2,3,5,8 I finaly figured out that pattern and found that the injector on the right side is letting in way too much fuel ,and thier new injectors! They are going to get me another one but it wont be for a day or so.

Excellent work for figuring out the injector problem!
