Here are the maps for my 383 SBC with Holley Stealth Ram intake and 36lb/hr injectors.
Not perfect, but good for 11.49@119MPH at the track and 19MPG on my commute...

Sounds like a fun project.
I think EDIS8 is the best way to go.

The wheel decoder is supposed to work on a V8, but I haven't seen any instructions for a V8 install.

I bought a adjustable vacuum advance kit made by Crane Cams. The kit allows you to tune the vacuum advance curve. It came with a limiter plate, but it didn't fit my MSD distributor. I ended up making a limiter plate out of sheet aluminum.

I could have used this knowledge the day I ran 11.16 @ 122.

Congrats! Glad to hear you got it working.

> I have full voltage at 11 on the db37
Pin 11 should be GND. Pin 28 is +12V
> x13(off of 11) is the only place on the ms board I seem to get any signifcant voltage at.
X13 should be floating. It is connected to pin 29 on the DB37.
> why are 20 and 31 ground when they should be 5v?
Just because you measure 0V doesn't mean they are ground. To check for ground, you should use a ohm meter to measure the resistance to a known ground pin.
What is the voltage at pin 1 of U5? It should be slightly less than pin 28 of the DB37.

I would get the power supply circuit working before going any further. Check the polarity of the diodes and make sure you put enough solder to completely fill the barrels.

Randy,
It depends on which version of code you are using. Read the following post...
http://www.msefi.com/viewtopic.php?t=6086&sid=9a1c53692a733dc9aa150c55fdd1a834
I think they just declared 024s9 as stable, which would use Megatune 2.25b417.
I've been running 024s7.

I bought my second kit from http://www.glensgarage.com/ . The kit included everything needed, case w/CNC machined ends, MAP bulkhead, etc. Just add solder! $140

I've got 17x8, 5.72" BS wheels with 275/40-17 tires. I'm using a 5/16" spacer.
Your wheels have about 5.95" BS, so I would guess a spacer about 1/2" would work.
My coil-overs are 10", 200lbs/in. The tightest clearance is between the tire sidewall and the spring perch.

Power for the injectors should come from the Main EFI relay. For my V8, I ran two 14 gage wires from the
relay, one for each bank of injectors, and split them out to each injector with 18 gage wires.
The MS also gets power from the Main relay to pin 28 on the DB37.

On my '78 280Z, I grouped every other cylinder in the firing order:
INJ1 = (1,2,3)
INJ2 = (4,5,6)
Using alternating really smoothed out the fuel pressure pulses compared to simulatneous.
I did the same on my V8 240Z, grouped every other cylinder in the firing order.

My brother and I have been talking about brewing our own' date=' but that takes money$$$. I know Don Manzo (dmanzo) brews his own and it is supposed to be pretty good! If I make it out to Gilroy this year, I'll pay him a visit.

I just brewed a batch yesterday, 11 gallons. It's fermenting as I type. I'd be happy to walk you through your first batch if you decide to try homebrewing.
Time for another Homebrew...

Congrats, Dave!

This is the only thing about messing with experimental code like this.
I know what you mean. I'm still using the 020i code. I haven't noticed any problems with it.
I'm afraid to find out what's been added/fixed in the 021 code, I might be tempted to try it.
If it ain't broke...

Hey V8Z,
I just did this swap and I also found the 300ZX seals to be a little tight on the 240Z spindles.
I just figured they would "break in" after some miles. I plan to check them after about 500 miles.

Don' date=' the rims look nice, but why the change? Were you not happy with the Centerlines you had on there? Curious. You going autocrossing now?

Hi Davy,
I'm trying to improve the handling of the car. I'd like to do another open track day once I feel the car is ready.

Congrats, Mat! It won't be long now...

Do you have stock springs' date='or coil overs?
nice wheels 94-96 cobra[/quote']
I should have mentioned that I have coil overs, front and rear.
Thanks,

Thanks, Guys.
The back spacing is 5.72".

I just finished installing some new(used) wheels & tires on my 240Z last night.
The tires are a bit big for the wheels. They came with the wheels so I'll use them on the back
and buy a pair of 245/45-17's for the front. The 275's barely fit on the front and the right side
will rub when turning hard left.
- Re-drilled 280Z stub axels and drums in the back. 5/16" slip-on wheel spacer
- Z31 5-lug hubs, rotors, and calipers in the front. no spacer needed

I would start with a fuel only install and then switch to fuel+spark after you have it running and tuned.
I very simple install would keep the AFM and only require a new TPS, O2 sensor, and a vacuum line to the built in MAP sensor. If you ditch the AFM, you will need a new MAT sensor and will have to rewire the fuel pump relay.
You can splice into the stock harness, or make a new one. Most of the wires you need are in the stock harness, except for TPS and O2.
I used a TPS from a `85 200SX Turbo. I think others have used a TPS from a 240SX.

I've got version 020i dated 10/14/04.

I installed the Extra code about a month ago. I'll have to check the version when I get home. I'm running fuel only, for now.
The readme says to get the 020i.zip file and update it with 020i9.s19.

The .6" is the spacing between the holes in the board. You want the spacing between the resistor leads, after they are bent, to be .6" as well.
