lag filter. yep i think that is correct.

getting back to the leanout issue.

i see the same in my WB logs yet it does not cause me major drivabilty issue. but it is still a little evident SOP. if you are in AE and higher MAP it makes sense that it would lean out if that VE table at say 2000 rpms and 70-80 MAP is short on fuel. that area was never datalogged? also the pressure drop may cause fuel to fall out as i stated. i paid attention to what rpm/map i was it when the lean spike occurred during AE and then added some fuel there in table. i was fearfull that the BLM correction would eventually remove it if 02 reads rich in those cells but since one is not in that cell too long may not happen. also i run OL all the time so no corrections will ever occur. i am at 122-126 accross the board with fall cool air temps.

consider fattening up those higher maps to crutch AE?

 

I can't fatten up those cells anymore. They are pegged at 99 in VE1. If I up VE 2, my lower map blms drop, and some of those cells are down to 4-5 because the VE2 is so high.

I'll log it and post the results.

If you run OL, it still reports blms?

What do you set your OL AFR at then? Just whatever gives you the desired result?

 

1. if you cant fatten up VE (100) that tells me BPW may be off. mine is accurrate yet mine is 100 net in some cells. i could be wrong on that. maybe not.

2. blms not reported in OL. i really dont care as i flip to CL if temps change seasonally then i do global 5% higher or lower in table.

3. i had it as high as 132 then 128 then 126 now 124-126 or so. car seems stronger at 126 and drives better. IMO.

reason i went OL was to get a better idle. seemed A/F waivered too much and rpms moved less and surged less in OL. my experience.

 

Factory injectors, factory chip, and blms were way off and needed considerable amounts of fuel.

181 is factory, factory injectors, factory pressure.

 

If you set the BPWC to factory, factory injectors, and VE1+VE2=100% or more you will be out of injector. In order to get more fuel you need to change up the BPWC to a higher number. VE1+VE2=automatically limited to 100%. If you put 140% total, all you will get is 100%. You could raise the BPWC, but 181 is already about the highest I have seen. Your best bet is to hit a salvage yard and find you a TBI off of a 305/350(preferable). Other than that, consider the washer mod to your fuel pressure regulator. Basically you shim the spring with a washer, taking care not to drive the spring into coil bind. Next you recalculate and reset your BPWC for the new fuel pressure. Then drive it and recalibrate your fuel tables. In my experience, if you add 25% to the BPWC, then subtract 25% from the global VE# (VE1+VE2) you will still be fairly close. That will give the injectors a longer pulsewidth and should help out that lean condition. Have you changed the .ECU file so that you can read pulsewidth out of the ALDL port?

 

I tried to get winaldl to spit out spark and was unsuccessful.

I have a new spring coming from TDS. Pressure is only at 12psi now, so I can bump it up some more.

I just hope getting it out of lean condition will get some milage back. I just got 10mpg on 145 miles! EEEK

 

Was 42mph in OD... shifted to Drive

Eventually had to shift to drive, PE @ 45%

Don't make too much fun of my Wot, I've only just dabbed at it. Trying to concentrate on drivability, and just thought that would be a way to see if I'm running out of physical fuel delivery ability.
