Yes they are OEM tables so they will work with the stock maf system. There are probably tables sperate for the decelleration routine.

Out of extreme curiousity have you just tried forcing open loop all the time, with the bit in the FAA bits set to 0. At least that way you could see what the tune is really doing before closed loop has time to mess with it.

On a curious side note your lean problem happens around those spots where the EGR is supposed to be kicking in.
Yes I am in full time open loop (it is bit 4 in FAA right?). BTW: closed loop produces the same affects. I have both the periphery bit full time open loop, and changed the open loop load tables to "0" from 0 - 3000rpm

To your curious side note: Are we talking about the 1500rpm lean, or the slight lift off while boosting lean? My egr is enabled, but I changed the EGR Advance to equal 0's because I find it drives smoother in the area where the advanced timing took place.

I'm just wondering if you disabled the egr what would happen

You know strangly enough this comment got me thinking. This issue happens whether the egr is on or not, and earlier in the year I turned down the EGR advance values to zero and it made the car drive better, so why not turn the HOIM timing down some more? It turns out that the car doesn't like anything near what the factory timing was set to. It has to be set lower than 15degrees in order to run nicely and match wideband to afrmap. Why won't it allow me to compensate with fuel?

D-VO....I am curious if your disabeling the closed loop has caused issues. There may be something related that got turned off that is causing the problem.

Might want to try and block off the EGR completly. The darn thing isn't really needed any how and a cleaner intake is always good.

Nah, I mentioned that in post #61. It goes lean at 1500rpm in both open loop and in closed loop. I'm still confused as to why adding to the asynch tables had no effect for me.

I guess the only thing that's stopping me from eliminating the egr completely is actually finding the block-off plate.

Block off plates are 5 bucks on ebay.

Could your lean spool tables cause the issue??? I know it usually doesn't kick in until 2500 rpm, but it is worth a shot to take a look.

Cool Thanks! I have lean spool disabled. (zeroed out lean spool start and stop and periphery bit)

<---Has no idea what the "Airflow/Hz Raw Scaling" table does. I haven't looked this table in years, and it seems that its back to haunt me. I changed these values to match someone else's posted settings back in 07', and unfortunatley with the install of the omni map sensor these settings were off, and in turn caused both my lean problems. Thanks for the help guys.

Reset the table back to stock and try tuning again.

It's the old MAF scaling table..still does the same thing.

Thanks, the Asynch_Acell_Enrichment table looks ok but the others not

Well i'm reasonable sure the accell enrichment base temp table is wrong but it should provide what it would look like.

If you're very rich on peak load, maybe you're exceeding your max load on the map? Are you scaled to 300? Could you be going over 300 on E85?
