End of Injection Timing Open Discussion

[Mr.owl]

I'm currently working on my tune trying to basically do the same thing you just did and god am i lost. I'm running a 60123 from lunati worked out my eoit needs to be right around that same 146 area but i know nothing about hex like at all. I'm using eextrav0[1].001[mod_v0005_03_02]v6_1.xdf or so it says. What in the world do i enter? Any help?

I'm no good with hex. I don't think u have to change anything in hex if you changed the eoit you should be good to go. Have you tried ve turning after you set the eiot ? What is your AFR running now ?

I believe the EOIT table in the xdf shows degrees after TDC of the prior compression stroke.
If you right click on the table header you can see the hex which is in terms of 90 degree pulses before TDC of the upcoming compression stroke.

For my stock B-body the hex value is $50, and the displayed value is 270.
The hex converts to 450 degrees (5*90 + 0*5.625) before TDC of the upcoming compression stroke.
This is equivalent to 270 degrees (720-450) after TDC of the the prior compression stroke.

Hope this helps, and others please correct me if I've missed something.

For some reason it would only take if i entered in hex value so mine shows 60 stock I'm at 66 now and in calc view i see 146 now instead of 180 that i had at 60. My afris pretty much useless as a reference currently because i didn't log my last run to see how much it was pulling but seemed to hang around my target 14.3 at idle (e10) and 15.6 cruise but again no way of knowing whst it was doing there. I'll be flashing my base ve table on and taking it from 157 to 146 this weekend

Are you going to be using theTrimalizer program it will speed up the process and very easy to work with

Oh yeah i love trimalyzer only way to go

Need to be careful when talking a degree value for EOIT to make sure changes are as intended.
For the 146 degree case discussed in the above posts I see both $66 is 574 BTDC compression (146 ATDC) and $1A which is 146 BTDC compression.

I'm talkin $66 eoit

Did you change every temp range for EIOT the same amount ?

No just where it's normally 60
