But how would you add something that doesn't even appear in the list?

I would imagine he did start by flashing a tune from a car with similar mods. Just wasn't sure if it was something that should be corrected (and if so how would I do it)?

Joe, enable / disable?? ...

I noticed a difference in the DTC Processing between the factory tune and dyno tune files on my LS1B 2000 Corvette. Should it be corrected?

Here are the differences:

In the Factory Tune,...

Finally fixed.

Replaced the FPCM and flashed it with the Nano and SPS. No more codes or dashboard lights!

Light is steady, not flashing.

I purchased the VCS Nano. It also won't clear the code from the FPCM. It does show the commanded and actual fuel pressures match and the duty cycle varies and...

So I'm still poking around with this thing. I logged fuel pressure and get 43.5 psig at idle and around 55 psig with key-on and engine-off. Then I looked at the fuel pump duty cycle. It goes...

The co I purchased the ECM from said they can get the FPCM and program it for just under $200. Don't know if thats for a new or used FPCM. I found them new for about $80.

I was thinking about...

I got it. Went into:

C:\Program Files\EFILive\Drivers\Utilities

and used the EFILive USB Manager to delete and reload the drivers.

Seems to have fixed it.

Its been a while since I've updated since everything was working and I didn't want to screw it up.

I just downloaded 8.2.16 (had to manually download), installed, and now when I launch V8 it...

Ok, last post and I'm done searching the internet. Found this:

the two DTCs, P0606: Control Module Internal Performance and P069E: Fuel Pump Control Module Requested MIL illumination, are both...

I found some notes I wrote down (from this site) years ago about the P0606: It doesn't necessarily mean the PCM is bad.

"When you get DTC P0606, log the PID GM.CPUFAULT to get a number that...

Tried the replacement ECM today.

Nope, same codes as before (I haven't done the CASE relearn yet):

P0315 Crankshaft Position System Variation Not Learned Current
P069E Fuel Pump...

Yup Sn00p, I know that now!

Replacement ECM arrived today. I hope to try it on Sunday.

Thanks again. I ordered it. May not come in until next week.

Then I'll see if the P069E Fuel Pump Control Module (FPCM) Requested MIL Illumination is real or not. From what I've read, the bed...

Talked to a co that said "we only sell units programmed to the VIN # given so if you have a VIN # which shows that OS we will have a unit for you factory programmed with all 8 segments".

I'll give...

Checked out that site. It also came back with the OS as 12617631.

Of course I see it was my mistake. The ECM shows 12617630 but the tune file does have the OS as 12617631 (12617630 is the...

Ah, guess I'm out of luck on that. But I do have a copy of the stock tune that I downloaded from the ECM when I got the truck.

Ok, what is SPS?

I've been using V7.5.7 (Build 293) and also have V8.2.2.286.

Thanks!

edit

Pulled the ECM. It has two numbers on it:

12612384
12617630

A flea-bay search shows these were used in all kinds of vehicles. Runs around $100. I would load the factory tune (I downloaded a...

I got the truck (used) 6 years ago. I suppose the previous owner could have swapped the ecm but the tune I pulled off looks factory with no mods.

Guess I better start searching for a replacement.

Vehicle is a 2008 Silverado. For the past few years its had:

P0606 ECM/PCM Processor Internal Fault
P069E Fuel Pump Control Module (FPCM) Requested MIL Illumination

I haven't been able to...

Will my EFILive V7/8 scan the 4WD system on my 2008 Silverado?

Engine = E38
Trans = T42

I'm trying to diagnose a DIC message to service the 4wd system.

I see the same DTC info when I scan...

Yup, its an FPFCM :-( Guess it takes the GM scanner to pull codes from it (that will probably cost $$ for the dealer to check). Hopefully the FPFCM is causing the P0606 and not the other way...

I'm trying to diagnose my 2008 Silverado that just threw:

P0606 ECM/PCM Processor Internal Fault EPA Pending ($00) "Integration/Manufacturer expansion"
P069E Fuel Pump Control Module...

I'll try the copy to clipboard tonight! Maps (V7) is doing what I was need. I going to do the same thing with a combination of Charts (V8) and a spreadsheet.

The speed actually isn't too bad,...
