I happen to be on the dyno right now with a FPCM equipped car 2010 camaro.

I had to use a different scalar/offset than you did. What I did was measure voltage at a about 27psi and another at 58...

send a email to [email protected].. Explain the situation and what you'd like to do. They are smarter on the GM stock reprogramming (called SPS) than I am on what is compatible with what.

I...

That is correct.. You need GM reprogramming software to do that.. We have this. There are ebay sellers that can do this too.

yes..

Also people should realize there is a fairly wide window of fueling that makes the exact same power.. A NA setup will make almost identical (less than 5 rwhp if that) between 12.5-13.0
...

I understand. Sounds like the FPCM will always estimate lower FP than actual as it is only "subtracting a calculated fuel line pressure loss"

There is no chance you are accidentally having your...

I replied you should ASK Mike Noonan.. then gave a positive plug for his book as it was helpful to me. It cost NOTHING to ask Mike about this..

Good luck.

I add boost to engines with 11:1 all the time.. Like LS7.

You'll be fine.


Pick a good injector for this build.. one that comes with injector data. You'll want a 2 bar map sensor and...

3-5% are very tight already.

It will never be 0%.

This is a very dynamic thing.. The humidity can change.. we have no compensation for that.. the temp of the fuel and therefore the...

This what they were saying with TFS heads back when they came out.... We found you can shim the pedestal and get a nice wipe pattern on the tip. A roller tip is just a easy fix for bad geometry

I just double checked.. and it absolutely does have that ramp

see image.. you can see your file name in it.

The VSS showing 158 isn't ideal. It's because the TCM isn't there.

The wiring for most ECM's are pretty much exactly the same. It wouldn't be a huge deal to reflash that computer as a 2010...

IAC is out 0.. meaning it cannot lower the idle anymore.

The IAC is either bad, or there is a airflow leak... vacuum leak, throttle body blade position, etc.

Easiest way to check IAC is use...

I know.. I would ask Mike which setting to use..

4x cam sprocket.. Late C6 Z06's cam sprocket are the go to normally (3 bolt)

Is the bucking worse at 1500-2200?

There is a huge hump in your VVE table in that spot.

When i got started doing this.. the only widebands you could get were ones you had to build yourself with a parts kit from digikey and a circuit board out of Australia.. We did fine. You'll be...

For such a simple setup you can use the stock narrow bands to ball park in the wide open fueling. 880mv-900mv will normally have you at 12.4-12.8:1

Do you happen to know y=mx+b for that fuel pressure sensor?

Have you looked into EFiconnection?

I did a 502 Ramjet with a early setup that used a distributor and 411 then we redid it a few later with coil per cylinder. It ran on a C5 vette OS. Just...

A log might be helpful. Even if it doesn't run.

Mike Noonan at EFIconnection wrote a book about LS wiring swaps. He would be a good person to ask. I have his book somewhere and seem to remember a good section on A/C stuff. His book helped...

Those injectors are fairly old and are "lazy" compared to what is out now days.. You can get them to work just fine .. but having proper injector data is going to be absolutely critical.

But.... ...

I've heard people shy from them on street engines. I've never taken one apart and saw any wild wear.. People think titanium and whoo wow... Really it is almost as hard as steel but almost as...

You could.. and I would zero out injector tip temperature on this. There are plenty of OEM GM calibrations with it zeroed out with no issues.

Map sensor scalar/offset are defined.. should not...

Yes.. do this or somewhere in between is likely where it will end up.. maybe compare the differences and multiply the DIFFERENCE by .5
