I own both. Neither will communicate with the pcm. Hpt or efi live.

I wasn't sure what they call their custom OS'. I am picking up another pcm today. Should i look for any other modules while I'm at the salvage yard?

I cannot get my stock file to write to the PCM. I checked fuses, downloaded the latest HPT before I started.
The only thing I can think of is the header hit the starter pole and arced during the...

Is the limiting factor the boost level? I mean if I can run 8psi now can't I adjust the current OS to run the 408 with maybe 6psi? (maxing the MAF and fueling dependant)

Sorry guys. My work computer won't let me on the forum so I am using my phone. It's a 2002 Tahoe 408ci, 60# injectors, TVS2300, LS2 DBW TB (i have an adapter harness), want to go to 2 bar map if...

I just need running cos to make the 3 hr drive to the dyno....

I think you are exactly right. My OS was for the first Flex Fuel series trucks, plus it's an '02 which I guess was kind of a cross over year for the DBW TB.
I'm still trying to get a grasp on all...

I have been working with a known tuner to get my latest project running. It’s a 2002 Tahoe and I'm putting in a 408ci with a TVS2300 on top. I am trying to go with a 2 bar MAP and a COS from EFI...

Can't you just adjust the parameters? Such as reduce the timing it can pull to 0* or not to engage below 255mph etc?

Is there a list somewhere of dyno tuners that use EFI Live? I'm looking for a tune for my new build. I am wanting to go 2 bar MAP SD tune with COS3. I have no idea how to even begin with that so I'm...

Wish I had known about this:
January 28-29, Secrets of EFI Calibration, Dallas TX

What shop did you use in Tx? I'm looking for a good EFI Live tuner in the Dallas to Oklahoma City area.

Im still using the stock computer. The fueling is still controlled through the PCM. I added 42# Ford SVO injectors, an inline walboro 255lph external fuel pump, and a Kenne Bell boost-a-pump on a...

Yep, magnacharger m112. Makes about 9psi, cam, 4.10 gears, 6.0L swap and a 4L80E. Makes about 500 to the wheels:)

I'm pretty pissed and happy right now.
Pissed because it looks like the pins not making contact were causing all the problems. :bad:
Happy because I think its fixed. It shift sooooo smooth and...

Just tore the PCM apart and I think the :cussing:@$*%ing pins are NOT seated all the way into the PCM so they are not making contact with the wiring harness. GRRR I hope thats the issue. I'm sure...

First post was AC volts, second post was ohms.

Maybe it's not the correct pin outs? Frustrating....

1.5 ohms or so in park, moves around between 1.5 and 2.0 in gear and tires rolling.

3.5 in gear at 0mph up to 12.xx at 40mph. Varies with truck speed. Seems to be working as advertised.

Gonna be around for a few? I will go see what I get...

This is the meter I have. What should I set it on?
Test with the tires turning?

Also the converter is not stock. 2600 stall Vig triple disc.
The shift kit is a TransGo HD drilled to the middle setting by a performance trans shop that I know does good work. The shifts are...

OK, so today I tried to test that sensor. I jacked up the truck had another person put it in gear and let it roll up to about 25mph. I got no voltage reading from the sensor at the PCM or as far back...

Ok, well Im gonna let it be for tonight. It's 2am here and I have to work at 730:bad: LOL So hopefully Joe will have time to take a look and see what he thinks. Thanks again for all your...

Something seems to be working. I noticed on the log the 90psi constant pressure is now adjusting and right at the shift it drops to 8psi or so. So I guess the tq managment is doing its job, I just...
