No, we had to make tuning changes to lower load as I was hitting 330 load at 24psi on pump gas. So we had to do injector and MAF rescaling then it still was hitting too high of load so we were going to do some more rescaling and also raise base idle pressure to add fuel and in turn reduce load further.
Our goal was to have load be around 275 on pump gas where I was so we have room on it for when I do the E85 tune.
Why do we need to lower load you might ask, well there is a hard coded load cap at 360 in the ECU, so you cannot go higher, so we are trying to make sure we don't hit that.
So when we tried raising base pressure is when we found an issue with something (not sure yet) and realized pressure wasn't increasing enough. So until I figure out the fuel pressure problem and get a full retune on pump I wouldn't be ready.
In theory I could revert to my old setup that I had last week and refine that tune a bit, but I don't want to waste my tuners time or my money for a tune that is just temporary. I'd rather fix everything and get it running properly.
