Need to look at my low RPM spark. I know I need to log my Base Spark, but what other tables modify base spark?
Thanks,

Need to look at my low RPM spark. I know I need to log my Base Spark, but what other tables modify base spark?

Update: drove 50 miles this afternoon. Still minor surging in lower RPM (idle-1200). Very minor and drives out of it, which it wouldn't do before. Will have to log all spark modifier data to see...
I would also check B3313, DFCO, and see what it is set to. If it is 120c +, then DFCO is turned off. This is usually done to prevent lean spikes during decleration that can send erroneous data to...
No, B3313 needs to be turned off (set to 122c +) during AutoVE to keep it from sending a lean spike into the BEN table, both Main and Boosted, when declerating.
B3313 will just be one of those...
hquick,
Reprogrammed B3313 back to 40c and drove to work this morning. Much smother with and without cruise control. I would say 99% of the surging under deceleration is gone.
Been fighting...
Been working too many hours to plug it in. Will do it tonight and let you know towmorrow.
Lonnie
Thanks. 104*F=40*C
This may be the long lost cure to my surging at very mild deceleration.
Lonnie
Got the answer to the DFCO part, just need a "normal" temp to put back in {B3313} after AutoVE.
Lonnie
Probably should cut/paste a current {B3647} into the basic tune also.
Lonnie
This is probably where my surging at very mild deceleration is coming from.
What should the "normal" value be?
Thanks,
Lonnie
Okay, I have had a lot of folks try and help me with this deceleration surging problem, and I am ready to start over and start from scratch. Please let me know if I have this in the right order or...
Looking in the tutorial for AutoVE, the only mention of DFCO is on page 6, Open calibration {B3313} "DFCO Temp Enable" and Set to 122 degree C.
I do not see where DFCO is turned off or back on?

http://forum.efilive.com/attachment.php?attachmentid=996&stc=1&thumb=1&d=1159733379I borrowed this flowchart from another thread and I have a question. Running a COS w/boost in open loop, isn't both...
Will this work with V1 or will I have to buy V2 as well?
Lonnie
If I understand this correctly, this will basically make AutoVE obsolete...But we will need to buy RoadRunner and an EFILive License, correct?
Lonnie
If I recall correctly, the pulldown table does not go up to 335 for tire size, so can you enter the tire size manually?
Lonnie
What AFR are you guys trying to tune to for idle at normal ops temp 14.63 or something leaner?
I have a Map logging IACDES_B by ECT, but all the readings log in PARK/NEUTRAL and I have a MN6 but...
I have a TT Vette and just flunked the emissions test. HC (hydrocarbons) was at 1300, limit to pass is 220.
Are the Random Tech High Flow cats burned out?
Thanks
Lonnie
KAZ Motorsports,
Still in work. Nitrorocket has been helping me, but his schedule and mine are keeping us busy and tuning the Vette is not currently the top priority.
More to come
Lonnie
Thanks Mark. This should be interesting. I am running leaner than stock almost all over the RPM/MAP range except in boost, which will not affect the emissions test. I will go down this Saturday and...
Our county has done away with emission tests as of 1 Jan 07, and of course I need one in Nov to re-register my '02 Vette.
Here is the problem; I am running twin turbos, bigger injectors, Custom...
Okay, now that I have it clear that 80kPa is atmospheric here in Colorado Springs and 125kPa is the correct reading for 7PSI boost, here is the question:
I have been using two maps to do AutoVE,...
dc Justin,
That is why I come to this board. Someone out there always applies a little common sense to my problems and helps me see the light.
You'd think with my math background I would...
TAQiockness,
Yep, that works if you know what the MAP should put out at this altitude, 6000ft above sea level. Unfortinutely, the 2bar is already installed and I do not remember what the OEM MAP...
