Hey everyone-
I am looking for a startup base map for a sr red top with 2871rs and 850 injectors.
Car has map sensor and iat sensor. I tried searching AEMs site but I think im about 10 years to late to find anything worth a shot.

I know some one out there has this setup because it was like the build to build back in the day.

Any one with a map and willing to share?


Thanks,

J

I'd even go with a MAF setup tune if anyone has one.
Just need to get this car going after 5 years of sitting.

Some things that would help.
What sr20? S13/14/15.
What model of AEM? Series 1/2/Infinity 506/508.
Also, you should not NEED a base map. Every AEM ecu I've dealt with comes either pre loaded with the base map, or you can select the base map for your engine using the AEM tuning software.
Once you select that map, scale the fuel map up or down to match your injector size, as well as selecting the proper dropdowns through the setup wizard to match your sensors that you have.
It should start and run at that point if done properly. If you don't know what I mean about scaling the fuel map, there's walkthrough videos on YouTube from a couple people.
Basically, say the stock map is for stock 370cc injectors, and you want it to idle on the 850's: Scale the fuel map down 44%.
However if you have aftermarket larger cams, you'd might need to scale it down slightly less due to the larger lobes bringing in more air.

If your intention is just to get it able to start and idle, scale the fuel map for your 850's, it should start, watch the wideband (assuming you have one) and adjust the fuel map more or less, until the ratio at idle isn't pig rich or super lean.
Beyond that go get it tuned.
