will the good 93 computer fit any gen 1 mark? and like someone else asked, what kind of performance increase are we talking about.
Super dumb question alert.
Where is the computer located?

Computer's by the steering column between the dash and the pedals. Not a noticeable power gain unless you actually dyno it, you might be able to notice a small economy improvement. And it's not gonna fit a 96.

this thread makes me wonder what ECU is in my '93... but its too cold for me to wanna go outside and give a crap... :lol:
i dunno, side by side the differences are startling and very significant
800 rpm higher rev limit =6800 rev limit
6-8 degrees more wot timing for a total of 32 degrees
no speed limiter
all of those differences WILL show up in real world performance, no dyno required...
which is likely why the early marks in a good state of tune run 14.60's where the 94-95's run 15.0-15.3
thats about a 6-8 car length advantage in the 1/4 to the 93 model!!
siiiiignificant if you ask me.
feel free to leave that "free hp" for someone else to enjoy
\
bang for the buck says "dont wait"
after the swap your gonna want a tune, so you might as well gain all you can before the swap...IMHO

What is our speed limiter set at? Does it vary by year or calibration? So far I've only had mine up to 100.

I've seen that info before, I'm just saying it's probably not going to be a change you can feel by the ass-dyno..
The '93's have no speed limiter? Any idea on the difference from a '94 Z4H0?
Thanks
z4ho was year two of bean counters and warranty dept...
its not one that i woul "seek out"
z4h0 is usually found in the 94 models
its not set to a mph, its set to a driveshaft revolutions measured by the VSS
early 93's dont have one, the others are all very close if not the same

I've had mine to 120+ Mph... I wonder if I've got the good one... what would it be limited at if I do not have the good one?
127ish depending on wheel size and rear gear...
LSC tap out a little quicker due to the 327s.
again it's not "MPH" based it's based on driveshaft revolutions, which will vary between base and LSC models...well the driveshaft revs dont vary the accompanying MPH varies.

Now I want to take my dash apart and find out. How hard is it to atleast see the number on?
no need to take the dash apart.
at the most you remove the lower dash panel "that your feet hit" when you pick your foot from the gas to the brake.
There are two screws at the bottom front of the dash, and one push pin up by the brake pedal that holds it in place.
the PCM it'self is held to a small shelf by a plastic C clip.. just pull the C clip down and then rotate the rear of the PCM that is closest to the firewall down towards the brake pedal.
On the rear of the PCM there is a cover over the J port, usually there is a sticker affixed there...that has the catch code {this is the tear tag) and the catch code is also printed ON the PCM connector where the wire harness connects.
should take no more than 10-15 minutes to get the PCM code
and about 96-98MPH for untuned 410 cars
