Question How many gallons of gas when at "reserve" marker?

In my '94 I'm noticing when the fuel gauge reaches reserve, I am only able to get about 13.5 gallons of fuel into the tank. What are others seeing? My '87 with the same size tank usually accepts...

Re: Can?t install spare tire carrier. What?s this in the way?

Mystery solved from a previous owner. :cheers: These were used for mufflers with vacuum actuated valves, but those valves were pinned open, and these parts not removed. I can plug it and remove them.

Nope. Many modifications done long ago by previous owners.

My 94 FSM shows the same, so later today I'll get her down from the lift and see if that one is missing.

Re: Can?t install spare tire carrier. What?s this in the way?

My 87 has a much larger vacuum ball on the same position. I'll pop the hood when I have time later and look at the Z.

I didn't even pick up on the fact that the solenoid is disconnected....

Question 1994 Power steering leak. Anything unique to know?

I was under my 94 and noticed there's a healthy amount of gunk under the power steering pump area. Before I go investigating further, is there anything unique/special to the ZR-1 for the power...

Thumbs up Re: More BMCB BIN spelunking. A few unknown addresses with changes.

Todd, thank you so much for that insight. I may put these back to stock and see how the car reacts. I have two anomalies I haven't had time to chase yet.


1) When cold it loves to stall when...

Re: Aftermarket Head Unit Question

A couple lessons from recently installing a similar Pioneer NEX head unit in my '94. I'm going on the assumption a 90 and 94's radio wiring is similar, but the below is based on my '94.

Post More BMCB BIN spelunking. A few unknown addresses with changes.

Doing a binary comparison on BMCB and the BMCB-based chip in my car at the moment, there's a few differences unaccounted for in the XDF I'm using.

Values below are in hex.

Re: Code 61 with secondary system removed?

Given the above it feels as if "Max Vac kPa to Close" maybe should be something like "Max secondary Vac kPa while port closed" as it appears to be testing the existence of any vacuum while the...

Todd, nice work. I didn't look at the flow chart before, but that 3.4kPa does come into play for system diagnosis.

Re: Code 61 with secondary system removed?

What are the chances the value names themselves are slightly misleading? I don't have a commented/disassembled file to read. I'm working on creating one in spare time, which isn't much lately. :D....

Thanks, Todd, I also see 0x55H (min vac to open), then 0x26H (min vac to close) of BMCB.

With the conversion you gave...

Min Vac to Open

Re: Code 61 with secondary system removed?

I opened a base BMCB.bin and the values with the same XDF are the following.

24.44 max vac KpA to close: This seems to roughly align with the FSM saying if the vacuum to actuators drops <21 kPa...

Re: Code 61 with secondary system removed?

Here we go.


<21 kPa to the actuators in FULL mode, DTC 61 set.
Any vacuum at air inlet valve actuators in NORMAL mode, DTC 61 set.



Interestingly even though I had a 61 stored, the...

Re: Code 61 with secondary system removed?

As far as I can tell, yes, the full power light is on any time the car is on and she dyno'd 445rwhp a couple weeks ago so not puttering around like an L98.

XfireZ51, I appreciate you sending those over. It looks like mine are currently set to 17.43 and 24.44 as min/max.

Making sure I understand the concept here.

As-is, the minimum kPa to ever open...
