A few random $8D questions

[JeepsAndGuns]

Getting readdy for my 7730 $8D swap exparament, I was prepping a bin and have a few random questions from parameters I went through.
I decided to start with AXCN, which is a 5.7 manual trans bin. It shows as being for a vette 6 speed. I couldnt find a camaro 5.7 5 speed manual bin, only 5.0. Did they make a 5.7 manual bin for the camaro?

Fuel cutoff engine speed.
Its set to 10031.02 RPM. Seems really odd, but figured it was set to max to disable it. The slider is almost all the way to the left, and moving it to the right instantly changes it to super low numbers. Thats what's really strange. But I manually entered in the rpm I wanted it to be (4800) and saved it, and it seems to save it ok. So is this normal? I also noticed a fuel cutoff min temp. That was set to max, I'm guessing to basicly disable it. I set it to 0 to hopefully make it active all the time.

CCP.
There is a flag called 16 Hz CCP in use. Its checkmarked in AXCN/vette bin, but not checkmarked in AXXC/camaro bin. I am using the CCP solenoid from a 95 1/2 ton $0D truck. Should this flag be checked or not? Anyone know what the difference in the vette and camaro CCP is? I looked at the wiring diagrams for both and they are both wired the same, and also wired the same as my current solenoid. But I dont want to burn it or the ecm up by selecting the wrong setting.

VSS.
Will the 2kppm VSS I have now even work with the 7730? There is a flag for magnetic VSS installed. Its checked in the vette bin, but not checked in the camaro bin. I guessing leave it checked?

I think thats it for now.

rev limiter is normal behavior... the rev limiter is setup in the code to compare reference pulses, which require a 16-bit divide operation that limits the ability to easily "adjust" via sliders unless you were dealing with really low numbers(which you saw).... works fine if defining it manually. since it's based on reference pulse time, a different equation is needed depending on the number of cylinders in the engine.

that flag chooses between controlling the CCP at a 16Hz or 32Hz rate. i'd do 32, 16Hz is a bit slow for my tastes. i don't know why GM ever included this as an option unless they used solenoids that didn't move very quickly, in which case 16Hz would make sense.

VSS.... what kind of signal does yours produce?

[Six_Shooter]

There were no 5.7 manual Camaros produced from the factory.

If you have an optical VSS or rather a signal that is the same as an optical VSS(which it should be), then leave it unchecked. The VSS signal in your case should come from a DRAC/VSSB as a single wire (brown IIRC), which would have the same signla s an optical, which IIRC is 5V TTL.

I'd grab another XDF and see if the Rev limiter selection reacts the same. Sometimes XDFs are not set up in a way that is intuitive, or sometimes not correctly.

[JeepsAndGuns]

I compared the vette5.7 and camaro 5.0 bins, both the rev limiters were set the same. Tried another XDF and it did the same. So I guess thats how its supposed to be.

My currently installed VSS is the 2k ppm from JTR. #1 in the following link:
http://www.jagsthatrun.com/Pages/Spe...eedometer.html

But they list #2 for 90-93 TPI systems, saying squre wave and sine wave, ac and dc. Thats why I wonder if it will even work. The 7730 has two wires for the VSS, B9 and B10, with the colors matching the wires from my TBI harness (yellow and purple). However the old 7747, and my current 7427 only use 1 wire for VSS input with the other tied to ground. So should I connect both wires to the 7730 like in the 7730's wiring diagram and see if it works? Or will it mess something up.

That should have the same characteristics as this sensor: http://www.painlesswiring.com/webcat...rchField=60115

I have used this sensor in a vehicle that I originally installed a '7747 into, and then later installed a '7730 (Running S_AUJP).

For the '7747 I tied one side to ground.

I'm pretty sure that when the '7730 was installed I connected both wires to the ECM just like a magnetic VSS. It worked with both ECMs, just read half the speed on the '7730. Later the 2 PPR sensor was replaced with a 4 PPR sensor, for accuracy. It also helped clear up some return to idle issues as the truck was stopping.

OK, I'll try it as is. I dont have a problem swinging the money for the correct one. But I didnt want to buy it untill I see how its going to run with the 7730. If the 7730 swap expariment goes good, then I'll buy the correct one for the better accuracy.
