Pulling tune

[L31Sleeper]

would that be like an injector driver ??

[JOHNBOY]

Yes. The FICM is the injector driver. A separate driver is needed on LB7s and LLYs because of the high voltages needed to run the injectors. 96 and 48 volts respectively. The new injectors are lower voltage and can be run by the Bosch ECM directly.

What is that box just under the intake air tube ?

The "FICM" is only on a LB7 or Early LLY right?
The 06' LLY doesn't use the FICM correct?



Thanks !

The 06 lly you are talking about really isn't an lly at all. Its really an lbz detuned to lly hp levels.

Correct, the 06' LLY doesn't have the FICM that's in that picture, it uses the LBZ type computer and injectors.....as BBaller said, it's basically a LBZ with detuned power in that year.

Hmmm didnt know that, I was wiring a DSP5 switch up for a friend but Im pretty sure that the LLYs dont have that...

I would guess that FICM = Fuel Injection Control Module?

Makes sense the ECM's in the same place, I was a little confused when I thought GM moved it to the engine of all places?!

That is a picture of an LLY.

That is a picture of an LLY.

I know, I posted that almost a year ago before I knew...

[JoshH]

Haha, sorry. I didn't look a the dates...

[ScarabEpic22]

All good man, plus its better for future reference for those who dont!
