LFN injector constant is time per mass rather than the normal mass per time, so you need to make the value smaller for higher flow injectors.

Yes, we actually have a 4 lobe LNF cam kicking around here somewhere. We tested it a few years ago, but abandoned it after the larger 3 lobe testing was so successful. The LNF is already designed...

That's what I like about the ECMs in the Regal and ATS. On those you can adjust the pump event timing and even set them up for more or less pump lobes. The ATS uses a 4 lobe fuel pump drive.

HPFP wear does not seem to be substantially increased. I imagine there is added stress, but nothing that has caused a bunch of failures.
Yes, I could set up some S3 cams for you.

Some of them had stops installed to limit the phasing in case of failure or bad ecm programming. Then I set them up and tested and found they still had .050" piston to valve clearance worst case. ...

ZZP S2 LNF cams are 216/212 @ .050"
Duration numbers on the product page are listed at 1mm. We do that because the specs that GM release for the factory cams are measured that way.

ZZP S3...

What area? There might be someone close. Otherwise, we do them every day. [email protected]

And that's fine. No one can say that you have to like it. I just can't see calling it horrible when it has worked very well for a lot of people. That's all I'm saying.

"Horrible idea". Interesting how all of the fastest lnf powered cars are running our horrible design.

I understand the concern about fuel puddling, but it is simply not a factor. If we were...

If you run the maf in the lower charge tube and mount the 5th injector there as well, you will run into maf spikes from fuel hitting the maf, even if the maf is first. Getting on and off the...

If the meth controller is designed to control a pump, then it won't have the correct duty cycle curve to work with a fuel injector. A typical meth pump does not do anything at low duty cycles, so...

Nice work on the build. I like the style that makes it more like a GM specialty build than a mod car. I've been trying to decide how to set up my Corvette interior, so this gives me some new ideas...

LOL, hi, John. I see you haven't changed a bit.

I've run into that as well. It couple be mislabeled and supposed to read degrees C.

The 60 and 80 lb injector information provided here will not work properly. Using the voltage multipliers, the flow rates still max at 63.5. The only way to provide an accurate flow rate curve is...

Anyone have a manual trans file you could share?

You can purchase our tune along with a boost controller and get a nice tune right off the bat. We are lowering the price on our turbo swap tune the same as we did on our K04 tunes.

It's not the o2 sensor. The injector duty cycle jumps significantly at the same time the O2 starts reading rich. It is a real reading.

lol, good call.

I'd try a full write if you haven't already. Sometimes it is required to get all of your adjustments to flash correctly.

Did you notice how much the VE Airflow jumps in the log? It's already higher than the MAF reading to begin with, but then it jumps about 35% even though there are no jumps close to that in your VE...

You also need to consider the amount of time it takes for fuel to travel from the injector to where it needs to be for efficient combustion to take place. I do not know the velocity of fuel...

You plotted your diagram backwards. The exhaust valve should be closing as the intake valve is opening, and a higher number injection angle is more advanced.

I believe this is what the op is looking for- http://www.youtube.com/watch?v=RfT3Q0r2buY&list=UUhj8GFjtgFSXPl4hGNlmphQ&index=1&feature=plcp

:) This was done for entertainment purposes, only. We...

Yes, altering the table by 2 will move the cam 2 crank degrees or 1 cam degree.

Yes, if the tables show -10 for intake and +8 for exhaust, the result will be 18 degrees of overlap. Remember, that...
