JDM Evo 8 doesn't have Map sensor
I recently just received all my bolt on parts and I just realized that my 03 Evo 8 doesn't have a map sensor... Ohoh
How's the tuner going to log boost without it? Or how is the car even running without a map sensor? Can I easily add/wire up a map sensor on? If so, what do I have to do? On the USDM evos, you can easily spot the map sensor right on top of the intake manifold but in my case, no bueno 🤦*♀️ HELP! https://cimg4.ibsrv.net/gimg/www.evo...922646ca9b.jpg https://cimg1.ibsrv.net/gimg/www.evo...8dbace01f0.jpg https://cimg9.ibsrv.net/gimg/www.evo...cfaaafa67d.jpg https://cimg7.ibsrv.net/gimg/www.evo...b78c93b5b2.jpg |

Thanks, so pretty much i just have to run 3 wires from the map sensor to the ecu (pin 73, 81 and 92) and drill a hole on the that port where the map sensor is suppose to be? im a evo noob atm so, just to clarify, theres no way to log boost if i dont have a map sensor? also what about tuning wise, car cant be tune without it? thanks for your help 🙏 |

Can't log boost but you couldn't really with 03-05 USDM evos either because the MAP Sensor would max out. You can still tune the car no problem, just would need to use the normal factory load-target system.
and also like im still on the stock 8 turbo, not as much boost is present but when I get all the bolt on parts installed i want to be running around 23-25psi of boost and this is where i would need a map sensor, correct? Thanks! |

Right cuz USDM evos come with 1bar MAP sensor but in my case, is it safe to say that theres no such thing as "maxing out" because there isn't a map sensor in play?

No you don't need a MAP sensor to do any amount of boost. The tuner can still tune via load-target like it is from the factory. If you want a PSI-target tune then yes, you need a 3-bar MAP sensor
