Haha "woop blew a boot"
Sounds great. Probably get alot of unwanted attention that way though. Mostly from those guys that like to write tickets

So I am having a strange problem that I can't figure out. Rail pressure will track right along pretty as can be until I put my foot in it, then it will lag a little bit, the regulator mA starts to compensate for it, then all of a sudden the rail will max out. When it does this it pulls like crazy. Sometimes it will sit there for a second, other times it drops back off when the mA starts coming back up to correct it. You can see it in this picture of a log. This was on a 2000usec tune.
Obviously the pumps will hold rail because they flat max it out at 3500rpm. I am almost leaning towards an electrical problem with the fpr wiring, dual fuel controller. Just because of the way it spikes and the ecm tries to bring it back down. Any thoughts?

Would suck if that was the case, it is a brand new fingers controller.
It doesn't do it on smaller pulse tunes, I'm assuming because the regulator isn't opening as much.
Could it be bad regulators?
Any other thoughts about what could be causing this? The FPRs are obviously going wide open when the rail spikes even though they are not commanded to, the controller is brand new and I just redid the power and ground to it, which didnt help. The FPRs are both LBZ's and supposed to be new.
Probably in the reg tables in the tune. Look at table B1010. Last 2 or 3 cells in the bottom probably need increased. I would try like 100 more MA in each of those three cells and see what happens. Is it surging when this is happening?
The only issue I have with that is the mA in this log that is jumps at is still up in the 900 range and 45000mm3. It is not at the bottom cells yet.
It does surge but not cyclical, just a wild pull when the rail goes full bore.
Finally got some gauges and threw them on. I'm thinking that these injectors are a little larger than 100s.... I'm making 75psi in fifth on a 1650usec tune. This tune blows the tires off at 55 or less, and will spin them hard at 75 when the converter locks.
Somewhat. It doesn't track well under high load but I have it set to go max rail so it goes wide open when I do. Still working on it to get it right.
I do know that a 2000usec tune will lose traction hard at 100mph. Scared the shit out of me when that happened.
So at 75psi the 366s aren't being driven hard at all, which is understandable because the gate is bypassing all of the turbos. Overall boost is 75psi, atmos boost is only 25psi.
Mind you this is still only on a 1650usec tune, which with 100s shouldn't be much more than 600hp or so I wouldn't think. The 1450usec tune is hitting in the mid 60psi range with 20psi from the atmos.

It will be more than 600 hp. That's probably in the mid 700s with that setup. I can guarantee you it has more hp than any single 66 or 71.
Tuning is getting very close. Took a log of a soft 5psi launch on tune 2, 1650usec, 190mpa. Per the log it went 0 to 100mph in just under 7.3 seconds..... if that is anywhere accurate, which it should be considering the speedo is dead on, that is a deep 7 sec eighth.
I'm getting more and more curious about these injectors. I have the receipt from ii for 100s but they aren't really acting like 100s to me. They love rail pressure, the difference between 160mpa and 190mpa is incredible.
