    First nitrous log

    I started this over o N54 and figured I'd post here for the added exposure.

    I finally got around to figuring out why my nitrous wasn't working. I found a broken wire for the solenoid arming circuit. A little background on what I've put together.

    I'm running fbo except for exhaust, G5 on newest firmware. Everything is NX and the kit once belonged to FBIS. See his extensive review for more details HERE. No way I can top what he already put together. The only thing I changed was converting it to a wet kit so I don't have to rely on meth for fuel.

    I built a fuel cell for both meth and race fuel so I could discontinue using the windshield washer reservoir due to all of the fires. I'm using a Walbro fuel pump and and Aeromotive fpr to keep the fuel pressure at 50psi. I'm using a 31 n2o and an 18 fuel jet due to the 18 being the smallest jet I have. This should produce a 50 shot. I'm using Torco additive mixed with 5 gal of 93 so it should be at 108 if I remember correctly. I threw away the can already..lol This is in the fuel cell and I'm running 93 in the car.

    The below log is without meth and progressive ramp over a second from 40-75%. Looks like I need to add some more fuel below 6k to richen it up a bit and stop it from cutting in and out as shown in the beginning of the log. During the 4th gear pull, I got a cel for cylinder 6 misfire. I'm sure I need to clean the intake valves at nearly 40k and the spark plugs only have about 10-12k on them. It only happen once but I didn't push it again.

    I'm really puzzled with how much boost over target there was in 4th. Car definetly comes to life on juice! Looking forward to some constructive critisism. I already know I should be running race fuel in the car as well.

    Just that boost targeting was fine. I should run race fuel, not an additive, and suggested their backend flash with nitrous. I plan to stack Cobb and the JB4 at some point.

    Yep, I've read all of that already along with Gerorge Smooth's posts. I may look into using some better nozzles for the fuel delivery. I did a flow test on the fuel going through the shark nozzle and it does look pretty pathetic at 50psi...lol I'm running the car on map 2 and you can see the overboost. I've also read that it could be due to not having time to adapt yet as well but I'm pretty sure it's boost creep. I added a little fuel from 6k down, to try to keep the afr just under 12.5, and I'm going out to try it later today. Once I get it activating right and logs looking good, I'll put it on a dyno and see where it's at before raising boost.

    It's already fun where it is now. We definetly need to meet up sometime.
