Hey here is mine. It works pretty well. Here is what I have:
1987 Supra Targa 7mgte
Stock ignition coils and ignitor
Stock engine internals and manifolds minus 2mm MHG and ARP head studs
Greddy intercooler
Tial 50mm BOV
HKS 3000 pipe
Boss Jr. 60-1 Ball bearing turbo
3 inch exhaust with HKS Super Drager
Action Clutch 2800 lb pressure plate with stock disc
560cc injectors
43psi fuel pressure with vacuum line disconnected from AFPR
GM 3-bar MAP sensor
Uses the fuel pump resistor relay signal to drive the radiator fan on output LS1
Set ignition timing to the standard 10 degrees BDTC like with the stock ecu.
It starts within a second of cranking every single time and idles at 775 rpms when warm. I've tuned it myself using bits of maps from the base tune and other fuel and ignition maps I've googled. This is the best I've been able to come up with so far without any professional help. I just drove 1200 miles over the weekend on this map and got 23 mpg with it. I know it isn't the best I could get with it, but it is a decent starting point for you all out there. If any of you are professional tuners and you look at this map, I am open to all comments you might have to squeeze more out of this motor. I've only pushed it to 15psi (which was today) and it didn't knock, so that's good. I am running premium 93 octane E10 (since buying gasoline without any ethanol in it is illegal in Washington State for some stupid reason) and it was around 75 degrees outside when I did the datalog. Hopefully this is enough info for you all to go off of. Just trying to give back to the community who has given me so much.

What do I need to download to be able to see these maps. I downloaded the AEM.ems and every time I click on one of your maps, it tells me that the version I downloaded doesn't work with this. Thanks.
