$E6 ~ $OE ~ $OD ~ $31 ~ $42 VE Fixer Spread Sheet

[ninerscout]

I have logged data and now ready to use the spread sheet. Which "Insert New Near Idle VE Table to Tuner Pro" Correction Factor with or without Averaged BLM Tables. I am pretty sure I figured it out. I used with Averaged BLM Tables.

Thanks,

I think I need some additional information to help out. I think your TBI is before 1993? There are two TBI ECM's used from 1987 ~ 1992, 1227747 / 1228747. There is a huge difference between the VE tables used on the 1st generation TBI computers. The Near Idle / Off Idle tables were on PCM's from 1993 ~ 1995.

Let me know what you have, then I can better answer the question.

There's little tabs on bottom, one to left is for 1227747 $42. I think Dave put that in for me... Then near Idle and off Idle for the newer PCMs. I love it, have used them all now. Great work Dave!

Tips! When you highlight all cells in TunerPro History Table theres no way to copy, you must keyboard CTRL C to copy. Can also highlight all cells in the VE spreadsheet and CTRL V for paste or right click paste. A box will open and want to know how to paste, just click Tab and OK.

When you open your VE table in TunerPro you can do it the same way with keyboard but there you can Copy and Paste too.

Just play with it, if you mess it up just close it and it will ask if you want to save changes and say NO, then reopen.

I have both the 7747 and 8747 computers. I am currently using the 7747 since it looks like it has more support than the 8747. I am new to fuel injection and want to start simple. Is the 8747 better? I know it is newer since I took it out of a 1990. I played around with the spread sheet and Tuner Pro, it looks like I am doing it correctly. I am using the $42 VE Correction Table and pasting the Table at the bottom Correction Factor With Averaged BLM Tables in Tuner Pro. My BLM log is getting better with each chip I burn. I am also have some questions about the data logging but I will start a new thread in the Tuner Pro section.

Thanks

The '7747 is a good ECM and uses a two VE tables, one table to 3200 RPM and the other VE table is an adder table. The '8747 has one VE table which goes up to 4800 RPM. There are pro's and con's to both ECM's. I favor the '7747 because of the software that is available and lots of people know how to tune the '7747. EagleMark has very good information on the '8747 here: http://www.gearhead-efi.com/Fuel-Inj...hlight=1228747


For the more experienced tuner the '8747, having only one VE table to 4800 RPM is VERY NICE!

Well there's lots of rumors that there is no def files for 8747 which we know is not true. It's just as good an ECM as the 7747 and I wouldn't hesitate to use one.

But comparing the definitions the 7747 $42 is way more documented and I have compiled anything and everything and then some into the XDF and ADX for it because I have owned a factory 1227747 vehicle for 8 years. If I owned a 8747 I would probably put the time and effort into those files as well.

Is there any way to force the PCM to stay out of PE and AE for easier VE tuning?

Never mind I figured it out

set the TPS PE tables to 100%
and zero out the TPS and MAP AE tables

[EagleMark]

You might not like drivability or get good data with no AE.

[96lt4c4]

I will leave it on then.

There is the option of using Excel to "Sort" the AE Active & PE Active data from the exported Excel spreadsheet. That's kind of an advanced class lesson for using Microsoft Excel.

What is the history average table for?

[jaber]

If my BPW is @ 110, will this spreadsheet still work, or is there a way to?

Im running a 7.4 TBI, 7747, on a Caddy 7.0 engine. I am close, but wondered if this would still work on my tune?

[dave w]

Yes, you will need to use the '7747 sheet to tune the VE Table.

I have logged data into Tuner Pro and would like to know if I should be using the "Without Averaged BLM Tables" or "With Averaged BLM Tables."

I have a 1988 ASDX bin and $42 XDF file in Tuner Pro.

Without average is - course tune.

With average is - fine tune.

If most of the BLM averages are more than 138 or less than 118 use course tune.
