Default I need a good base map for 90 with greddy MSpnp and 440's.

Ive read a couple books about tuning and have realized im not the type to read about something like this and pick it up. Im just wondering if I could maybe get a base map to get me about 75 miles to my tuner.

Thanks in advance for any help.

The map that came with it should be fine, you'll just need to change the req fuel value.

So I could just adjust the required amount of fuel until I get an adequate a/f reading and that would get me where I need to go as long as its not too lean?

as long as you change the req fuel and cranking settings, but you should be good to go with that, but dont drive it hard until you see were your A/F is!!!! its not my fault if you blow it up!

If you have a PNP or any other MS for that matter don't load someone else's map. read the instructions and make the proper changes changes. Ie, cranking PWs, Req_Fuel, etc.


there are so many little options that could totally screw you over....for example, i could send you my file and it may have spark inverted and i could easily fry your ignitor right out. and id laugh.

Dont forget the cranking PWs so it doesn't flood when you try to start it.

Forgive me for all the possibly stupid questions. Now when Im doin all this I just need to watch the A/F guage and make sure it doesnt go higher than 14:1? Or is there something else I need to pay attention to?

Yeah make sure you're not going lean, and if you're turbo don't overboost.
Watch your coolant temps and what not as well.

Nothing Im doing is helping. Ive changed the req fuel and still stays lean. I know tuning cannot be this difficult. The car starts perfectly, idles perfectly, and sounds perfect at idle but just runs way to lean. I dont wanna hear READ THE MANUAL kuz ive read it almost all the way through. Srry if im sounding testy but this is trying my patience.

You set the reqfuel according to injector size and you tune the fuel table to the correct AFRs. If you can't handle tuning your own MS maybe you should have gotten a couple PC pros.

I can handle it I have a little experience tuning. If I can tune with a microtech surely I can tune with this. Its like anything I change has no effect.

You are clicking burn when you make a change right?

My bad just figured it out. I just didnt think that I would have to bump the req fuel all the way up to 20 to get the a/f up just to get a reading on the guage.

And I just found out that my rad isnt up to par and wont keep the temp down at stand still even with the awr fans and shroud.
