Hello, very new to the h2b scene I have a 2000 ex coupe with a stock h22a and ls trans mated. Just recently picked up a p28 w/ s300 v3 and was hoping for some help with a basemap for it. Right now it has a chipped p28 and was told it has a basemap for stock injectors, problem is previous owner planned on going turbo so it has 550 cc RC injectors and dies whenever coming to a stop above 1500 rpm. Not familiar at all with tuning software so i'm trying to get a good basemap until I can get to a tuner. Any help at all would be appreciated, thanks in advance.

Try this file, I just remade the injector size from my current H22 file that was using stock injectors.

I just googled & found the RC Injector Dead Time page: https://www.rcfuelinjection.com/Portals ... y_Time.pdf & I listed the Dead Time on the tune file using the 45psi fuel pressure column.

Wideband is linked to D10 & Wideband was an AEM UEGO so you may have to adjust the volt compensation for the Wideband offset too.
