did you install a wideband to see the fuel mixture? what you did is 99% guaranteed to lose poer UNLESS if the car oem is very lean in wot (99% of the cars are NOT lean from the factory in wot) , so i wonder how it became quicker by thismod

[@StupidBlokeStupidVideos]

@@ef9b16a1 definitely didn’t lose power. Most modern cars are set to run at a leaner ratio. The 14.7:1 air fuel ratio is the most efficient, and road cars are tuned around this or sometimes leaner for emissions. To make more power/torque, a ratio of around 12:1 is often more effective, so adding a bit more fuel to a petrol engine that’s been tuned for efficiency is actually likely to give it a bit more power.

[@machinedred]

Surely it's just gonna show a negative ltft ? And have zero difference after it's done a few drive cycles ? Can these ECUs be remapped via obd?

[@StupidBlokeStupidVideos]

The ecu can be remapped but this hasn’t been, and I’d have thought similar,.. I’d have expected any differences just to be filtered out by fuel trimming but they just don’t seem to be. It’s done probably about 1000 miles or more with them in and definitely runs better on them. It’s mainly noticeable at cruising revs than anywhere else. It is also noticeably worse on fuel though.

[@silureswarrior6045]

Yeah it will trim it down, along as the difference isn't too large it should be fine

[@benabusthethird9751]

Could the responsiveness be because the injectors are cleaner? Maybe worth cleaning the old ones and see if that helps?

@@StupidBlokeStupidVideos Its maybe to late answer, but you need about 30% bigger injectors to run on bioethanol/E85. With ethanol, the engine will run better due to a high octane rating of 104.
