You're not going to find one b/c nobody here is running RC 720cc injectors with the MegaSquirt. I think you got in a little deep with this MegaSquirt thing. It's supposed to be a DIY electronic fuel management computer... you need to TUNE IT. Read the MegaSquirt tuning manual at www.megasquirt.info to learn how to tune and visit www.msefi.com if you like forums. Seriously man, this thing isn't plug-n-play.

if that is the case then lee would not send you a unit with a base map for your turbo size and injectors etc already installed
fortunatly there are those people out there that understand that the tuning aspect is complicated and just want everyone to get the best product for their cars with minimal hassle

I've used Lee's base map for my car, and it needed quite a bit of tuning still. I basically ended up re-doing about half of the VE map, which can be different from car to car, esp when dealing with different sized turbos, cams, ect, which can alter the VE of a motor. The base map VE table is a great place to start, but dont just end it there..You WILL have to FULLY UNDERSTAND how to tune your car with the MS if you want it to run properly. Read, read, and read the MegaManual over and over, until it all sinks in. Read over the tons of posts on www.msefi.com, and just get as familiar with it as much as you can. Don't anyone expect this to be a plug and play type of setup, basemap or not..You will have to tune it no matter what.
This is lee's base map, both 250kpa and 300kpa map sensor configuration files are included. There is also one version of Megatune, and some msns-extra code in there as well,but most of us are running the MegaTune 417, and code 022i6.

If you want a start on the req fuel value, here are a few settings.
etx has 880's, and his is around 5.8(its in the ballpark of here) Lee has 780's, and is 6.2 I have 680's, and mine is 6.8
Dont use the req fuel calculator, as its not quite right for a boosted application. A good req fuel value to start for 720's, would be around 6.4-6.5

I have a question, and keep in mind I am an extreme newb when it comes to stuff like this, but what if you just take the readings from your MAP and IAT and plug it into the formula they give to find out the exact req fuel? Would this not work? so it would be
36,000,000*122*AIRDEN/4351.2(for 74 lbs)*1/2(?)
right? Or am I just way off?

Guess I am way off. Plus that 4351.2 is at 14.7. I guess a turbo application should be around 12.5 or so.
