trwebb26 Posted November 14, 2006 Share Posted November 14, 2006 I finally got my megasquirt running and I need to work on my HORRIBLE tune I've got in the thing. I'm looking for some pointers on how my Target AFR & Spark Map Tables should look. Post up your MSQ - or even beter post a jpg of the maps. Thanks!

olie05 Posted November 14, 2006 Share Posted November 14, 2006 How are JPGs better than *.VEX files, or even *.MSQ files? What is your setup? Turbo or N/A? Quote Link to comment Share on other sites More sharing options...
trwebb26 Posted November 14, 2006 Author Share Posted November 14, 2006 JPG's so everybody can see - whether they have a megasquirt or not. 78' n/a stock engine w/ stock injectors running MS&SE on a v3.0 board. 12x12 spark table and 8x8 target afr maps would be great!

Careless Posted November 14, 2006 Share Posted November 14, 2006 How are JPGs better than *.VEX files, or even *.MSQ files? What is your setup? Turbo or N/A? the files vary between firmware versions. some msq files have different code in different areas that will cause corruption errors on the uploaded code when sent to the chip, and might cause it to not interface correctly with the program (bad, especially on a running engine) and some VEX files do almost the same thing, if i'm not mistaken. however, the MS i built is still waiting for it's engine to be built. I gathered that above info from reading. Quote Link to comment Share on other sites More sharing options...
trwebb26 Posted November 14, 2006 Author Share Posted November 14, 2006 Most of the time you can load up the msq - even with the errors... just to look things over. I would never take somebody's MSQ and try to start my car with it. Just another reason why I'm interested in JPG files. Quote Link to comment Share on other sites More sharing options...
Clifton Posted November 15, 2006 Share Posted November 15, 2006 If I knew how to take and attach a jpg of them I would. I can send you the msq if you want. Quote Link to comment Share on other sites More sharing options...
z-ya Posted November 15, 2006 Share Posted November 15, 2006 Hear is an 8x8 table from a stock L28 (accept for 10:1 compression). It should get you close. I would enter this table and interpolate the other points in a logical manner. Then I would adjust your "Required Fuel" to get a smooth idle. Change the maps after the motor is warmed up. Your targert AFR sould be in the 13.5 to 14.7 range across all load and RPM points. You can get close with the logging feature and a narrow band O2, but you really should get it on a dyno with a wideband O2 to get the most power out of it.
