If you had an older truck with 4 speed (80's) and a late model vortec (97 roller) engine with carb manifold, swapping to tbi without the EGR and using the 7747 ecm what BIN file would you start with? I have a "ASCN" "ARHT" "ASDW" available but the vortec heads is making me nervous. Anybody running anything close to this want to hook me up with a copy of thier BIN file to get me close?? I was told that the vortec head motor will need the 454 tbi unit to flow enough fuel and air, but GM makes a tbi manifold for the vortec motor with the standard tbi unit.

Here is some information I have.

Don't mean to hi-jack this post but how sensitive are the chips. The reason I ask is because i want to burn a copy of my original chip from my 89 blazer but when I was removing the chip from its holder I accidently broke off two of the pins. I was wondering if I can carefully solder a piece of wire or similiar to what is left (hardly anything on one of the pins) of the pins and then install it into my Burn 2 and successfully make a copy. I know there are .BIN files out there and i've found one with the same BCC but you never really know how accurate that is. I mean my chip is an ANLX and everything on the screenshot you posted is correct data EXCEPT my gears are 3.73's which is RPO code GT4. Thanks for any help you might give me.

I've also broke pins on chips.
I've never tried to solder the broken off pins back on to the chip, because the heat used in the soldering is likely to destroy the chip. The internal circuits of the chip are easily burned with heat. The internal circuits of the chip are very thin traces only a few thousandths thick. It might require some fine tip filing, but maybe you can get enough of the plastic removed around the broken pin make an electrical contact. Then have a bare wire make contact to the broken pin and Burn2 socket when reading the chip? The Burn2 takes just a couple seconds to read the chip.
The excel file I posted with the screen shots off of I downloaded from Moates.net. I can't say the excel file I down loaded from Moates.net is 100% accurate.
What I can say is I have an ANLX .bin file I can email to you as an attachment. Send me a PM if you are interested in the ANLX.bin file.

A ANLX is an ALNX. Waste of time to solder etc... just to get the .bin file that's available anywhere. HTH
Nice collection Dave!
Do you happen to have anything for a 440 Mopar built engine with big block TBI and hybrid distributor? If not I'll just start with my big block starting .bin...

Start with a BBC .bin. The real challenge I see to using the BBC .bin for a 440 is the timing table.
Make a best guess where peak torque (RPM / Vacuum) is and use that as the max degree setting. Set the distributor initial timing to zero. Maybe an old magazine article has a dyno of a 440 engine, and timing curve?Less timing at low RPM / high Kpa will help with engine strarting. High Kpa (100 Kpa is WOT) but also there is high Kpa at engine start up. Low Kpa is idle ( about 30 ~ 40 Kpa). Timing tables look weird at low RPM high Kpa beacuse of engine start up timing.
Let me go on record, I have nearly stopped using / programming the '7747 ECM. In my way of thinking ... Why would someone want to use an old Windows 3.1 OS / PC when a Windows XP OS / PC is the same price?
If it was my 440 / TBI, I'd use a '427 PCM.dave w
I am going to have to make the upgrade to the 427 some day soon. But right now I am knee deep in helping freinds tune there 7747s and this 440 has been done for a year and I am just starting to tune. It has been running just to drive in and out of shop while we did the gear change, bumper, winch......
I also have factory timing curves for most Mopar, all AMC engines. GM and GM crate motor timing tables are plentiful.
Since I have already hi jacked this thread it seems like a good conversation place for one more .bin! What ECM and .bin would you use on a multiport injected inline six engine?

I'm figuring you have a distributor for the inline 6 that will trigger a GM OBD1 ECM. I think I would go the FWD 2.8 / 3.1 liter V6 .bin '7727 / '7730 route. The '7727 / '7730 is an 8192 baud rate ECM.

Well that opens the door to underhood mounting of the ECM as well!
I thought there was a newer ECM for MPFI on a 4.3L V6? Only reason I ask is the 4,3L Is way closer to start than a 3.1L.
Yes I have a distributor set up. About ten years ago when BillUSN1 and I started doing EFI on the old IH Scouts. I designed a distributor for it by machining the bottom of the distributor out of the motor being converted and putting a chevy top on it. Since then I have done just about any motor the same way.

I have not really worked with the 4.3 liter MPFI. I think the 4.3 MPFI ECM could be an option, but I'd have to do some homework to figure something out.
I like the option of an underhood ECM, and MAP sensor based EFI system for an off road use vehicle. The '7727 / '7730 are easily programmed to a different displacement, timing curve, and fuel map. I think with the correct ADS file, TunerPro RT can even data log the '7727 / '7730 V6. The '7727 / '7730 do not need a VSS, but a VSS is recommended. I think most, if not all 4.3 V6 MPFI ECM / PCM require a VSS.
