I had nothing better to do today, so I decided to sit down and analyze a few eprom images that I have gathered over time, and the result of this is a new .ecu file for Winbin that I will share with the rest of you.... I think you'll find a few things that both you and I missed in the past in there!
I've added all the parameters for highway fuel mode & highway spark mode....

Everyone else sleeping??

I want some feedback on this one?!?

 

I'm going to try it out. If it works, let me be the first to say (in my best Jazzy Jeff voice) I LOVE YOU.

 

woah, just as i was thinking of wandering blindedly into makeing my own ecu file, someone else does it for me.. Thanks alot man....you just saved me a headache or two...now to see how it works..

Good work! You mind if I toss this update onto my site for availability? I was hoping someone would pick up the ball on the ECU work, thanks!

Of cource I don't mind, things like this should be shared.... I'll see if I can figure out the maths for the rev-limiters as well toda, then we're nearly 100% complete...

When we were putting together the 6Ev004 version, the rev limiters were working OK, but thee was a problem with WinBin and the 2-byte values. Has this been fixed? It used to be that anytime you had a 1/x calculation where x=16-bit 2-byte value, an error would occur if the value of x was out of a certain bound.

 

Ah, so thats why.... It's a bug in Winbin.... Kind of explains why nothing made sense even when I could do the calcs on hand....

Are the enable temps C or F?

 

They are in F.....

ZaphodB, you've got mail.

Thanks Greg, I will update the ecu file and post the new one!

 

I've incorporated your additions/corrections into a new version of the ecu file now. Have alook at it and see if there is anything wrong, consider it beta for now.
