Lean at boost

[alanderson1978]

I installed an STS turbo last week and initially I was rich below boost and lean when in boost. I have adjusted VE and got the rich areas leaned out some, but it seems that my changes have no effect in the lean areas. It is not actually lean, but it is higher than commanded AFR.
I started off with 070818 VE Tune 1.hpt, then ran 0708181.hpl, changed the tune to 070818 VE Tune 2.hpt, then ran 0708182.hpl

Please look it over and see if there's anything I'm missing. I have changed the tune about 4 times total, this is just the last 2 from tonight.

A few things to not is I have the stock fuel pump and spark plugs. I plan on installing a Walbro 255 and NGK TR6's in about 2 weeks.

Thanks in advance

Part of the problem may be that you're not triggering PE until 5000 rpm and 90% tps.

But I'm hitting BE. At 105 kPa, Commanded AFR goes to 11.5, and Actual will get there sometimes, but it usually only gets to 12.5 or so. This happens even with a few pounds of boost.

Delete the MAF pid, no idea why you would log that in the first place.

It is screwing with airflow calculations and you are getting 28º of timing. You timing table is very screwy along with your VE. Only log what you need.

I'm out of town for a few days right now. I'm going to look over my scanner config and try to make sense of it before I get home. I was logging the MAF before I installed the turbo to work on my bias.
I guess there is a big difference between tuning a stock OS running in SD and a true SD system.

Thanks

While I was out of town, I changed my scanner config and did a log from the airport to the house. Attached is what i've got.
I got a fuel pressure gauge tonight and got it setup so I can watch it in the windshield. I'll see what happens in the morning.

I noticed that the IFR table does not go into boost. How does the PCM handle this?
Would a boost referenced FPR help?
