May be too much spring. Those are good to .675+ lift, and your running around .500? This would mean the springs are about .200-.250 from coil bind. You need to do some serious shimming or put on a...

You should feel lucky, I had to search for months, and bug some really intelligent people, who did a lot of math work to get that data. You got it in under 30 minutes!

If its the really short ZR1 injectors, they have an angled injector stream, they are not straight like most other injectors. Designed for their specific setup.

I bought this, and it covers a ton of stuff.....

Has anyone ever bolted their engine to and simply used the air hat and VE output to build their VE map?

Kind of the same way you would use the dyno for MBT spark tuning, steady state, cell by cell.

From what I understand is that minimum injector pulse is a setting that is the minimum amount of time the injector can be commanded open and still work mechanically.

Anything below that time the...

OK, then use the info in the excel sheet above. Its almost exactly what I use too for my LS3/LS7 injectors.

I just wanted to be sure you were still using the 2000 PCM and not an LS3 PCM.

The MAF curve looks just like it should, thats the shape you look for. I cant tell you if its correct or not, but thats the correct shape.

I glanced quickly and your ETC TPS Max vs % Max torque...

Those are 72lb at 58psi, you know that right????

You need;

IFR
minimum pluse width
voltage offset
short pulse offset (0-4ms)

Which PCM are you using?

I have both and think they are worth it. The begginers book has a lot of stuff you can find by searching, but I like having it all in one place!!

HEGO = Heated Exhaust Gas Oxygen Sensor.

Spark is a trial and error that you have to figure out for your specific engine. Or rent a dyno and do Minimum best Torque/Timing (MBT) tuning.

More timing DOES NOT always equal more power, and useing knock as a limit also doesnt work. You need a dyno to "tune for 93 octane" so you can set timing for the minimum amount of timing required to...

I think they should work out a deal that if you send in your old unit, so you cant resell it with the credits, that they could give you a new one with your credits already transfered.

A mailorder tune should be used to get you in the ballpark or get you up in running. If you have HPTuners & a wideband, you have everything you need to get it as close as you can.

You need to...

There is no reason to run at 11:1, you've spend thousands of parts trying to make more power then you purposely sabotage yourself.

12.5:1 is completely safe. In all the LS engines Ive run...

Ive got the info on the weld on piece, I was wondering how you attached the screen, and your link does work either :(

How did yo install this, and what did you use for screen?

When I VE/MAF tune, I set my AFR to 12.9 (.88 lambda) everywhere. Because your car should Idle, cruise, and WOT at 12.9 and be safe. Then at the end I set it back to the standard AFRs everywhere...

Whats the voltage range, or calculation used on the LC-1??? It might now have a very high resolution if its noisy, or you have a leak somewhere.

Here is what my FAST wideband looks like, very...

Ask them.....

Gregs DVD comes with the data for the (green top/fat body) 42# injectors and the 60# siemens (tall/skinny). The 60# injectors at 58psi are actually 72lb hr.

The STS tune assumes boost referenced...

Ive been tossing the same idea around for a while. I have the MAF and a Halltech housing just sitting around.

Are the pins the same on the older MAF and the new card style? Or do you have to...
