I'll spoon feed you my BS...... BUT IT IS NOT PROPER.....
Man this thing is so easy. I am good to get on the internet on the computer.
MLV does it just buy clicking, ANALYSE
. And somehow I can't get that right.
So I just pulled up the VE table and click and change things as I go. I just type in a higher or lower number till I get the AFR where it supposed to be in that cell.
Once you use it for 10mins you will feel alot better. It is not hard.
My advice. GEt with spike or any radom person that has a Lab top with a 9 pin cable adapter on the back. Download megatune and your maps. Write down the Ve tables. So you can look at them at home side by side.
Have a friend drive and carry you through the table. (different rpms and boost levels)
And where you go lean at cruise, type in higher numbers till your afr's are correct. That is as simple as can be.
Then when you get home compare it to the map that is not lean in that area. but plain and simple just get your afr's where you want them.
I'm sure with dyno time already spent, you will probably do best taking and adding from each map.
If I can do it, anyone can.
You have got your tunes, just work off of both of them to achieve what is needed.
But save the originals in the state they are in. You will always be able to go back to a good platform if something wierd happens.
And as far as things getting a little different with the weather temp changes, it happens. My car is now lean at idle. I had to richen it up.
I figured out why these cars are called tuners, you are always tweaking them somewhat. not alot, but small changes here and there.
Your good, just work it.
If you can't get a lap top. get a friend to drive and see at what rpm and boost on your gauge the map starts to get lean. Let out of it. (Cruise= vaccum level= KPA) (KPA= any pressure taken away or given to your Barametric pressure.)
Get an extension cord on your desktop. Hook it to your MS in your drive way, and add the cells from the not lean map from that point on. (rpm and boost/vac (KPA level) tell you which cells, at that point change those lean cells to the other values in the not lean map)
Where There is a Will, there is A-WAY!
If you send Brain a cute cat video or picture, he has a color schematic of which cells are cruise, idle, and boost. Or you can look for days on the ms manual. You need something he wants. LOL..... It is just good humor.
Pic's of girlfriend and we all would be more willing to find it for you. LOL
