Makes sense. Here are the fuel map, ignition map and setup. Fuel map is basically the base tune -50% fuel trim as the injectors are twice the size of stock.

Stupid autocorrect on my phone, I DO have a laptop and the software. And if a wideband is required and I don't have one, then how was the car tuned previously? As it did have a previous tune that was erased

I'm honestly unsure if I have a wideband. I have 2 sensors in the exhaust, one right after the turbo that is a 3 wire (I'm assuming that's just the normal O2 sensor) and a second just before the cat, I'm unsure how many wires that is and I unfortunately can't check right now. I don't have a laptop to use, I have hooked it up and played around with the EMS stinger software a bit, done some reading and all that. I have a pretty good idea of how the tuning works, main problem I'm having atm is not being able to read my afr in the software, it simply stays at 22. (I have tested removing the O2 sensor directly after the turbo and leaving it out in the open air, still reads 22, so I don't believe it's working correctly but I do have a new one on the way) I'm not sure what you mean by 'VE' and yes I can get you a picture of the current maps and settings.

Hoping to get it to a point where I can drive it around under 4k rpm. I called my tuner and he said I should be able to just adjust the fuel trim enough to drive it to the Dyno, but I don't have a good base tune. I can get the car running but barely moveable

Hey all, I recently lost the base tune i had on my rb25det r33 (long story) and I was hoping someone had a base map for an EMS Stinger V4. The software does come with some base tunes, but they aren't very specific, and have not worked for me thus far. The only thing that isn't stock is 740cc injectors, but I plan to just adjust the fuel trim in order to compensate for that temporarily until I can get it to a tuner. Thanks in advance, You guys are all legends Charlie
