Default VE at 200% on BS3
I have not came across this before. I put a BS3 on my supra at around 20psi i max out the VE table. Car runs great but i cant plug in any numbers higher then 200. I tried changing the injector opening time but that didn't help any under boost. My injector duty cycle is at about 70%. With the aem on the car had no issues making 1300rwhp. Changed nothing but the computer
What to do under these conditions?

You will have to change your injector flow rate constant. Is it an accurate number now?

Are your injector sizes setup appropriately for the rail pressure you are using?

Would have to see the file then, if the inj. constant is right maybe there is a correction table somewhere that is jacked by number less then 1.0.

Thoughts on this. Since i cant seem to figure it out i was thinking about adding fuel in the warm up table. They are at 0 right now but what if i go to the top of the kpa and just start putting fuel in there? Do that till i get my ve numbers close to 100 under wot? Never seen anything like this before

You either have to have the DAE logging feature added, which has its own harness for the various sensors. $600
Or some earlier boxes and firmware could have a fuel pressure logging feature added, again a marked wire out of a different plug was added.
Mine has the latest and greatest firmware, and I could not add it to mine.
The standard BS3 does not have it, I finally broke down and got a racepak so I could log fuel pressure with the bs3.
