I'm having this problem right now. Ever figure it out?

Took the Z out for a midnight ride.

Upgraded the flywheel to an Aluminum Fidanza 9lb. Accelerates much quicker now. For reference OEM flywheel = 27 lbs, Exedy = 16 lbs, Fidanza 9 lbs.

Not good. Makes me want to cage up. RIP

The fuse box was in fact faulty. MSA is sending me a new unit.

I decided to change out MAF's from the E60 to the slightly newer E61 model and the car is running much smoother. Eliminated a lot of off throttle backfiring. Second, I never liked the look of the all chrome heat shield on the air filter. Not going for a show car type of look. I considered painting it black but decided to wrap it with DEI reflect a gold heat material. First researched to make sure it does actually work so I could justify the function which it does. As far as the fashion goes I like it. I finished it off with some rubber welting around the edges.

Called MSA. They're having me ship the box back to them so they can have the manufacturer inspect it. Luckily my old fuse box still works because this process is going to take a few weeks to figure out.

Ok so I put the old fuse box back in. No issues. Checked voltage on the L & R fuse block with ignition on and power was only coming into the left side like it should. I'll be calling MSA tomorrow. 😕

Correct power is on both side of STOP bus bar with the fuse removed & ignition in the on position. Makes me think it's a manufacturing issue with the new box. Prior to install I had just drove the car to turn it around in the garage and replaced the fuse box. Never had any real wiring issues before this. The hazards don't work anyway so I'm thinking about just leaving this fuse out completely. I don't like the idea of masking a potential problem but the idea of having to comb through all the wiring under the dash to just have the new fuse box just be the issue is a bit of a turn off. Do yo

It's a 73 240z. It's got it's share of wiring modifications for gauges, rb motor misc. I believe I have it isolated to the stop circuit. I don't recall if I had to rotate the connector but the wire colors do somewhat match up..the msa wiring color isn't exact but I double checked that I didn't have it reversed, the plug will only go on one way as well. The stop circuit has constant 12v power on the left side of the fuse bus as it should, with the key to ON there is 12v power to both sides of the fuse is this normal or am I getting two 12v inputs into the same circuit? I'm going to mess with it

Hey guys, so I just upgraded my fuse box to the MSA modernized unit. When I put the battery cables back on the engine electronics and fuel pump kick on as if going to accessory power. If I remove the 20a STOP fuse I can put the cables on and the key will operate the acc power as usual. Any ideas on what can be going on here? Edit: I originally upgraded the box because the parking lamp fuse block was starting to melt out.
