Opening up a discussion on SR20VE +N1 cam tunes..
Mods please relocate this to a different location if you feel that this is not the correct place for this...Ultimately I would like for this to be a sticky once it gets populated enough...
Well, I would like to open up a discussion on our SR20VE plus N1 cam based tunes, so that we can all share our data and maybe in the future we will have a much better feel and understanding for what is the best tune for this motor. I will start off with one of the most sought after tune, which is SR20VE + N1 cams. I know a lot of people with SR20VE motors are headed towards getting the N1 cams and tuning it, so that is why I would like to populate this thread.
Well, I started off with the frankie.bin courtesy of payu, which you can get here ( n1 ve programs - SR20 Forum ). When I opened it up the upper rpm limit on the fuel map was 7200rpm, so I am assuming that after that, the fuel map will stay the same? Dudeman has also tried out the pito.bin but had some issues with lean conditions, so I think frankie bin is a better starting point. This is what I noticed with the frankie bin... At about 4k - 5.6k rpm, it would start to lean out to mid 14's afr, so in the upper TP (about 56 - 64)I increased the fuel to about 33 (again this is from 4k rpm to and including 5.6k rpm since 5.6k rpm is where I have the VVL activated; however, payu recommends 6k rpm, but I just wanted to see what mine does with an earlier activation). When the solenoids activates (after 5.6k rpm), I would leave the fuel alone unless you see lean conditions. I think this is a good STARTING point. I just got a G3 innovate today, so after I install that and mess with the logworks and datascan to also monitor knock, I will be able to get a more accurate data and tune and will update this thread accordingly. Currently I am just basing it off of my AEM Uego and eye balling my stock tachometer (stock tachometers are typically off by a little).
My plan is to first tune to about 13.3 afr from 3k rpm and on, and then while looking at the knock counts, adjust the timing map until I get almost no knock at all.
Anyone else please feel free to provide your thoughts and data about your tunes.
