Yeah I forgot to rename, fixed now. I figured a well-tuned CL idle should be able to take care of any dips in RPM when coming to a stop as well as increasing electrical load.

Remember what I said about entering CL idle? Forget it, didn't happen today for whatever reason. Idle PWM is static at 34%, which is the lowest bin of the cranking duty PWM table.

VEAL still pulls fuel out of the cruising and light accel area of my VE table. I fatten it up manually and after 20 mins of driving it ends up taking all the fuel out again leaving me with a bogging slow POS of a car. Do I resort to the pre-VEAL era and drive, log, analyze in MLV and import new fuel table (rinse, repeat) or set it on fire? Everytime I feel like there's progress, I'm taking two steps back the next day.

$5 for the solution


Edit: the retarded dip in the VE table is what I end up with after using VEAL. I've noticed it and I must be missing something here.

Edit 2: another drive; first startup and it settles into decent CL idle again. Still dips and almost stalls when coming off throttle after blipping. No amount of PID ******* helps. I have no clue why it does this one time and not the next.

Fattened the VE table again in cruise/low accel areas and it was ok. Once again VEAL pulled a shitload out right into bogging galore. WOT pull to 7k held 12.5 AFR dead-on per my target table. Yet the cruise area is a total pain in the dickhole.

Honestly, I have no idea where to start chasing this. Dimitris, interested in a euro trip?

Any of you gays have an idea?

I have a 2000 pretty much as your '99 only with A/C and just finished installing (a month ago) an MS2E from Dimitris.

Runs pretty good and I can PM/email you my tune if you want. PM me with your email if you want and I'll shoot it over.

Does the AEM AFR guage show the same values as the TS one in lean regions?

If your idle is pretty steady, you could try leaning out the idle to 16:1 or so and see if both gauges agree. (or look at them carefully while cruising)

I had a situation where the AEM and TS were showing the same values, roughly, in lean situations but once it was fairly rich TS was half a point or more to the lean side. This resulted in VEAL adding a bunch of extra fuel and boost cells were maxing out my AEM gauge at 10:1 AFR. It sounds like you might have an opposite problem.

If they don't agree, you can manually calibrate your AFR table until they do.

Gauge and TS agree to the decimal from full rich to full lean conditions. I suspect I made a dumb somewhere else.

What filters are you using for VEAL? I always set minimum RPM to 1500, min fuelload to 35.

You also need to set max TPS to 40% or so for low load areas (ie less than 70kPa or so), then tps > 40 and tps < 80% for the 60-90kPa, then finally TPS > 80% for the map > 90kPa areas. No way around if when you are only running on MAP.

VEAL filters are: RPM >1500 < 1500, fuelload > 35 < 400, CLT > 70. Nothing more. It does filter out warm up and accel enrichments right etc right?

Great success (moderate maybe, but success ) today. Made some changes and it's already heaps better than I had before. Started after 3 cranks and kept idling/warming up following my rpm targets. I do seem to have some intermittent TP AE kicking in (indicator lighting up) every now and then even at idle and foot completely off the throttle. I see the TPS gauge moving from -1 to 0% every now and then but it shouldn't activate TP AE right? I've even raised the TP threshold but it's still kicking in every now and then.

Another small drive and it was ok. I have no idea how to implement all the extra VEAL filters like in my previous post. VEAL did seem to pull less fuel out of the VE table and it was smoother. 2-3k rpm and ~70-80 kPa are still bucking although not as bad as before I think.

One annoying thing I noticed is that is has a tendency to stall while I'm parking. I turn in to reverse into my spot and it stalls. Fire it up, park and stall again. Stoplights etc are no problem, what could cause this?

All this driving was with low beams, rear defrost and heater on, still dips but noticeable less than before.

Starting could go a little quicker, but idle was dead-on today, despite some small dips when the idle valve opens and it goes super lean for a while. Seems to recover ok and hold it's target of ~950 rpm hot. Occasional off-throttle dips to ~600rpm but no stalls. Might try a bit more dashpot and fine-tune idle advance.

I've checked the log I made today and saw some lean spikes (again) with low TP and high(er) MAP, I've added some fuel to those areas and will log again tomorrow.

How do I go about adding the filters for VEAL for these conditions? TPS 0-40% ; 35-70kPa, TPS 40-80%; 60-90Kpa and TPS 80-100%; 90 > kPa?

I think that's the dashpot adder. I need to mess with mine a bit too.

Filters work now, had another go today. I'm still not 100% satisfied with the VEAL robbing me of fuel even after filtering.

Cell weighting seems good to me, still there's a lot of fuel being removed from most cells. You can see in the datalog where it pegs at ~18 AFR before it finally takes off. It holds 12.5 AFR at WOT all the way to 7k rpm though. Driveability is all I'm working on now.

Anyone? Tried some today, idle was oscillating bad. Just as I hoped at least that was fixed, this acted up.

Oscar

iTrader: (2)

More progress. Starting/idle is less fucky now. Lowered cranking PW some and oscillations are waaay less. Still have some idle dipping when parking and slow driving and constantly engaging and disengaging the clutch.

Lean spots in cruise and light accel are less too, though VEAL still likes to pull out some fuel. Feels like I'm getting close now though
