Cannonball89 Posted April 12, 2011 Share Posted April 12, 2011 Can someone explain to me how the AFR, VE, and IGN tables work in Tunerstudio? For the IGN table, instead of the Y axis being MAP as in Megatune, it is called IGNload%, so I'm a little confused as to what IGNload% is equal to. I thought it might just be a percentage of maximum MAP value, IE: I enter 250 KPA as my max MAP value, then 250 KPA would be 100%, 200 KPA would be 75% etc, but it seems that most people have been using 400% as the max IGNload% value. Why would percentages be used instead of the simple MAP Y axis that megatune uses? And what exactly does it mean? The AFR and VE tables are set up similarly but it seems that 100% AFRload% and 100% VEload% are the max values for those tables. I can't seem to find any information in the Megamanuals or EFIanalytics website explaining this. This is a bit of a problem for me, because I have MS3, and am therefore only able to use Tunerstudio, I can't set up Megatune initially then figure out Tunerstudio as I go. I pretty much am trying to make my own tune from scratch because I can't find an MSQ for MS3 for the L28ET yet. The problem is that when trying to copy data from the sticky http://forums.hybridz.org/index.php/topic/34536-megasquirt-map-information-sharing-all-code-versions/ into my tables, my Y axis is different than the ones in that thread because they are all from Megatune. So please help me figure this out, thanks. Quote Link to comment Share on other sites More sharing options...
mobythevan Posted April 12, 2011 Share Posted April 12, 2011 Without knowing much of MS3 yet I would say that most people are entering 400% because they probably have 4BAR MAP sensors. I could be wrong. Quote Link to comment Share on other sites More sharing options...
PalmettoZ Posted April 12, 2011 Share Posted April 12, 2011 I set up my car using Tuner Studio when I had my stroker engine, and its very different from regular MS. It was a NA motor though, not Turbo charged. Not sure if you can copy from existing tables for the ignition. I would contact them directly and ask these questions, since the website doesn't really support the Tuner Studio stuff, unless that has changed in the past 2 months or so. I was pretty frustrated trying to get mine going, alot of differences in nomenclature from the old to the new. Unfortunatly I think your on your own here, since almost all the info here is for MS I,II. Quote Link to comment Share on other sites More sharing options...
mobythevan Posted April 12, 2011 Share Posted April 12, 2011 I have an MS3 on order and hope to start through these issues next week. Hopefully I will become more useful for MS3 questions in the next few months. I will be in the same boat so we can bale water together Quote Link to comment Share on other sites More sharing options...
Cannonball89 Posted April 13, 2011 Author Share Posted April 13, 2011 Well I guess this is as close to a pioneer as I will ever be... I'd like to get the car idling sometime tonight (It's 2AM right now so I guess I mean less than 24 hours from now ) I think I will load the "MS3 example tune" that is included in the Tunerstudio software as a baseline, then set it to my engine parameters, and fine tune from there. I'm thinkin it will be close enough to get it started. The important thing will be to set my engine characteristics and injector characteristics, as well as my spark settings and ignition trigger methode correctly. These settings are close enough to Megatune that I think I can figure it out. Wish me luck Quote Link to comment Share on other sites More sharing options...
mobythevan Posted April 13, 2011 Share Posted April 13, 2011 Here is the best post I found about ignition load on the msextra forum: http://www.msextra.com/forums/viewtopic.php?f=131&t=36692&p=252965&hilit=load#p252965 Looks like if you set load calculation to speed density then 100% = 100kpa, that makes sense why people with 4 bar map have 400% = 400kpa. And Good Luck Quote Link to comment Share on other sites More sharing options...
lowrider Posted April 13, 2011 Share Posted April 13, 2011 For clarification, I'm using tunerstudio with my ms2 extra and it also uses the IGN load%. With my setup using the map sensor only the IGN load% corresponds to the map reading, the same with the fuel table. Quote Link to comment Share on other sites More sharing options...
Cannonball89 Posted April 13, 2011 Author Share Posted April 13, 2011 Awesome thanks. I guess I will just use 250% because I have a 2.5 BAR MAP sensor. Quote Link to comment Share on other sites More sharing options...
