Just some other thoughts.. are you using the right thickness sealing washers? I know incorrect injector protrusion into the chamber can lead to smoke

I was using the copper washers provided by DFI. 

No double washers or anything like that.  Double and triple checked.

If it is of any help, my 5x012 SAC's I got from DFI smoke like a 007 smoke screen

Humm not a good sign.


I ended up soldering on the 9924 backwards, ugh.  Too awhile to desolder it and get it turned the right way.

DOH!

I've put plenty of stuff in backward in my time... still never learn to check it enough times..  and things like forgetting to put the shrink tube over some wires BEFORE soldering them together?!

haha that's why I have to solder everything twice.

Couple of more question here. 

I have the 9924 in and soldered correctly this time. 

I know the VR has a + and - lead and the 9924 has a + and - input also.  I am assuming the VR sensor wires on turbo, Green and black, mean green + and black -?


Also I know you code as a min 4000 rpm shaft speed, but since my injectors are out and being tested by DFI I can't start the truck, so I am limited in RPM on the turbo to about 2000 rpm.  Will the vr sensor read that low on the turbo? 

I cannot for the life of me get the example for the freqmeasure library to read any values. 

I dunno if I fried the 9924 by having it backwards to start or what, but I get nothing.

I really doubt the polarity of the VR sensor is important.. it's an AC signal... I don't know if it give enough signal at that RPM to trigger the 9924, but I think the mode it's in says it's adaptive peak mode, which means when the signal is low it'll increase the gain

Do you have it exactly like the A2 model ?

2 10k resistors, with a filtering cap after them connecting + to - ? and the Cout 10k pullup ? Make sure the cap you use is non-polarity, ie ceramic.

The chip will not output crap, if it does not have the pullup on Cout.. I figured that one out after a day LOL. But it will count really low, Mine spins off to a couple hundred RPM.

Best thing to test, is just get a drill gun and put it on the input shaft and spin it while verifying, you should get it to atleast 1k.

Also make sure you wire Cout to pin8, for freqmeasure. You literally could just upload the LBB code to it at that point, and drop minimum rpm to 0 to check and see if its working.

Yep a2 mode

Pull up on the Cout pin 8. 

Do I need to do anything with pin 4 on the chip? 

I am wondering if I fried the chip by having it reversed 5v through ground pin.

I have version 1.1 on it now trying to test and see if there is any output, but I get nothing with my dewalt spinning the turbo.   I might try and order a new 9924 and see if that fixes it.

Make sure you set minimum_turbo_rpm to 0.

Pin 4 is bias, ground.

So I'll just set this for you.
1 vr+
2 vr-
3 NC
4 GND
5 GND

10 +5v
9 GND
8 NC
7 IO8 + 10k + 5v pullup
6 GND

Top left is 1, Top right is 10
Bottom left is 5, Bottom right is 6

Reversing it shouldn't of done anything it's a pretty robust chip.

Thanks for the stupid proof directions haha.

I'll try some more.  Min speed set at 100 it goes to output enabled and does noting on 1.1, with 1.0-1.05 it will start running through the cycle but I never get a rpm reading. 

Time to break out the multimeter and start verifying wires.

Since its on a DIP10 you can check for pin bridges, nothing should be 0ohm between any of the pins. If you diode check, i think 2 pins are like 1100ish

Also its really hard to solder that sob, no harm in pressing down firmly once you feel the pins are aligned well enough. Might want to check over the top of the pins to the DIP10 to verify connectivity as well.

Perhaps as a check you can write a new sketch using an interrupt on the pin to blink the onboard LED when it gets a signal?   Perhaps make it so it blinks once for every 10 revs

like

void PinISR(){
static int Count = 0;
static boolean Status = false;
Count++;
if (Count>=10){
Status = !Status;
digitalWrite(LEDpin, Status);
Count = 0;
}
}

You can also put a multimeter on the VR sensor pins on the AC setting, perhaps you can see if you're getting any voltage there
