My edited WinBin ECU file for the 747 is on the DIY ftp site. It's called 747-mine.ecu. Give it a try and let me know of any errors please.

Wow, great job on this .ecu

Can't find anything wrong yet!

 

Yours is the first ecu other then the one that came with winbin.14 that has worked.
I'm new, but I like what you added.
Thanks

 

V8 astro,

I might just be blind but I didn't see a max IAC limit in your .ecu. It might just be under a different name that I missed.

 

It's called Max retract IAC steps...in the values tab.

I'm glad it worked out for you.

 

I noticed that in your .ecu under array, for TCC limits you have listed them in MPH, in tuner CAt theses values are % TPS.

No I just read it wrong again, your right!

 

In your next release, It might not be a bad Idea to add the TCC forced lock-up in MPH @ 0x56E. Maybe even some other TCC params.

I say this because a few of us are finishing the 1/4 at over 100mph, which just happens to be the stock value, not really a good idea to have it locking at high rpms with a big stall.

 

0x56E you say...lemme get on that.

 

Here it is. I think that's all of the TCC stuff.

or

ftp://ftp.diy-efi.org/incoming/ and just look for 7747.ecu

 

Astro,

I have been having problems with max/min async PW values. It seems when I change the max value it effects the min value. Not sure maybe its just my computer, not sure. Let me know if they work fine for you.

Edit: It appears that when changing the min async bpw, to say a value of 002D, when you save the file , and re-open it the value magiclly becomes 2D2D.

 

I see you figured that one out too. I have the same problem. I have no been able to get WinBin to do double byte values. I may try another sceme. Such as doing the double byte values as an array with two columns.

I'll post back when I make the change.

Ok I tried putting the double byte values as an array. Looks like you can edit the bytes one at a time, but anything that is a DB the conversion doesn't work. This is because the first and second byte are treated as two different numbers so the WinBin converts them independantly.

If there is a DB value of $0318, it is not converted to #792. It looks at it as $03 and $18. So you get #3 and #24($18) converted separatly.

If you still want the new ECU lemme know...

 

If you could email my the ecu @ ryanhart@shaw.ca that would be great.


Another topic: My TCC doesn't lock up. All my boundrys seem in check, I do get a "NO high gear" flag in winaldl. Just wondering if any of the "flags" in winbin have any thing to do with the TCC. There is one or two that have TCC in there name but I don't know what there for. Just wondering if you have any knowlodge on this.

 

In your ecu the value "min temp for closed loop" yeilds a different value than that of tunercat. Changing one does move the value in the other program, so It s the same constant, just difffernt values.

 

I've found that some of TunerCats conversions are not the same. I will not say they are wrong...but I get my conversions right from the ASDZ 747 hack.

So if you divide 35 (*c coolant) by 64....you get .546875. This is what is used for my conversion. I've used the same method for the other 100 entries I added to the ecu file so far.

What does TunerCat use?

 

V8Astro, this should be the correct conversion:

C = (N * 0.625) - 5

C is temperature
N is the bin value

This holds true for the coolant value in L0021. The '747 also uses ADC counts, can drive 'ya crazy.

RBob.
