When I selected the 1000cc injectors for my car, I had not planned on E85. I just knew that at some point down the road my car will need them after I build a stronger bottom end for it. As an experienced tuner with standalone systems, I was confident I could tune my car to run them just as well as a smaller injector for start/idle/cruise and all conditions.

Well, tuning the UpRev has a bit of a learning curve, regardless of experience with other EMS. Matter of fact, experience with other EMS probably made it worse because I kept looking for things that are not there or not needed with this style of engine management. I also tend to require a certain level of understanding with what exactly I am working with before I will try and work with it. At any rate, tuning the UpRev with 1000cc injectors (with gasoline) was a little over my head as a first time project with that software. I was having a lot of trouble getting the car to run well in all conditions. I could make it start and idle, but then it drove like crap. I could make it drive great, but then it wouldnt idle. Etc.

So I decided I would make my life easier, preserve my engine, and learn on a more typical configuration. I elected to switch to E85 to, in essense, water down my injector size. Tuning E85 with the 1000cc is more like tuning gasline with 700cc or so. It worked great and the car performs great. I would like to think that should I decide to switch my car back to gasoline, with what I have learned with the UpRev software, that I could take on the task now. But, theres only one way to find out.
