Did the swap and all works good except the boost is often at 3psI then sometimes it works good. Used the 03 harness. So did I need to change a wire or sensor or use 03 pcm?? I was told maf sensor might cause issues but no codes for it.

 

Swap info I've seen is the other way around with new engine into older truck.

 

Post baro map ebp koeo and at idle and at 2500 RPM

03 used map
06 used ebp for turbo calc

Did you install just a base engine or ?? Swap any turbo sensors etc more info

 

I used the complete wiring harness, sensors, ect from the 2003 and just plugged it into the 2006 pcm.
KOEO......... EBP 0.00v, 6.3psi. MAP 1.32v, 14.75psi. MAF 0.04v, 0 lb/min. BARO 14.21psi. VGT duty 0%

KOER idle......... EBP 0.00v, 6.3psi. MAP 1.31v, 14.46psi, MAF 1.51v, 4.72 lb/min. VGT duty 42.9%

KOER 2230rpm....... EBP 0.00v, 6.3psi. MAP 1.50v, 16.42psi. MAF 2.66v, 15.18 lb/min. VGT duty 52.37%

 

I would have kept the 06 HPO system... a lot more reliable. save the old parts before disposing of the engine.

I know, just did it because I had it kicking around...

 

It's your ebp better make sure that it is plugged in

 

Seems the new sensor I put in was faulty...

 

Didn't the 03' use inferred EBP? Why it's reading zero.

 

I have been told that too but it reads the sensor and applies boost better with it in and in working condition..

 

Looking at your readings... they are 0v and 6.3psi across the board. Normally MAP+BOOST=EBP. And unplugged you can tell a difference in boost?
