Come on guys, we have a section for info like this, please use it. The Portfueler has to be retuned very often. The Portfueler does not have a temp sensor to adjust for temperature changes, therefor you will need to retune through different times of the year. You will even need to retune when runnign at the track. Tim97rs was able to run 6 or 7 runs before he began leaning out. This was because the engine bay began to heatsoak and the EIC was still addidg fuel for a temp that was 30* cooler.

When you get the portfueler the map is extremely rich and you will need to do a fair amount of tuning as it is. If you dont like tuning then you need to consider a different platform to work with.


The MS can be set up to a one time tune, the only difference is the range you are tunig is much greater and it will take you longer to initially get a good map.
