I'm still playing with mine. Having some issue with it not going into open loop consistently. Car is driving, boosting and fun though.

I've been working on HPTuners for the first time lately. 17-18mpg so far in a 7,000lb work truck. 5.3L.

Not sure if I can explain the shifting IAM. Mine does the same thing, depending on conditions.

I'll be swapping my TPS shortly and picking this back up again.

Hey ImprezaRSC I got an email from Project lambda which helped explain it:

"On your ECU the IAM is initialized to 0. If no knock is detected it will increase gradually to 1.0 and vice versa if knock is detected."

Guys, been having an issue that I think you may have insight on. Im running an ej251 with a TD04, so on partial throttle I can get into boost. Unfortunately we can't put the VE past 100%, so I end up running at 14.7. I'd prefer to keep it a bit richer just to stay safe. One option is to put my open loop enable at like 5-10% throttle but then you loose out on the niceness of having closed loop functions. I was thinking if you can adjust the airflow and load scalar so that the new "stoich" is around 13.7. Then you can adjust the VE table as needed to lean it out for idle/cruise areas. Any suggestions?

hey danscomp,

What injectors are you using? What fuel pump? what boost pressure?

On my setup, I dealt with what you're dealing with. After beating my head against the wall for a while, i just increased load scalar (left airflow alone) from around .035ish to .0402ish. Now I can go as rich as I want.

Hey, I'm running the 420CC WRX blue injectors, walbro 255lph pump and I peak at 8 psi right now.

At the moment I'm driving it with the open loop transition at 15% throttle input so I'm cruising rich. Not ideal. My current load scalar is 0.04819 as per Michael's suggestion.

What's your setup?

I have a 96 ej22 shortblock, ej205 heads, yellow top 500 injs, td04, apprx 15psi. I'm using a kemso 340lph fuel pump. This setup is powering a white 2000 Impreza Rs. Going up to Rallyfest this weekend at Team O'Neil, don't know where you from, but if you're close, come through.

I also have a cammed 2001 sedan RS 5mt that I am considering turboing. I have nearly everything I need to do it, so just trying to make up my mind.

Do you have a youtube channel? It'd be cool to see how your car moves. Mine is Immortan Jon. I have a few clips there.

Good luck
