I am not going to give away the farm, but I have figured out a way with EcuTeK RaceROM, so that you can use use a maximum of 100% DI and 100% PI, effectively giving you 200% fuel delivery. It is not something within the standard operating procedures of EcuTeK, but it is in there (in RaceROM) if you know how to look at it. This is how a lot of my tunes work on 350+ whp vehicles (turbo kits and superchargers) running stock injectors on E85.
In regards to Speed Density etunes, you are more than welcome to speak to any of my customers running pure speed density on their turbo kits. There are a few out there now and all of them are running quite well and are very happy with the tune. Though I will say it took quite some time to figure out how to make it work well, while using EcuTeK RaceROM to dial in compensations, and of course it is still being revised for improvements.

thanks i will definitely look into that for other tunes i'm working on, though with all the large injectors i've been tuning it's not a problem i've had to solve as of yet. i'm very interested to figure it out just for the sake of science, though
. please don't be mad when i figure it out and sell the farm lol.
i'm going to be doing a full speed density tune this evening for a local turbo car, and i don't expect it present any major issues, especially given the ability to create any comp map i could imagine needing. it's being done because the maf on the particular kit he is using is extremely inconsistent below 1.4-1.5v, and is effecting drivability to the point that speed density looks like a better option until we can get a new maf tube. i'll be sure to update the community as to how that goes.
