What are you guys logging in terms of the max load your are seeing? I could post my timing map for you guys to compare but only problem is my loads I am sure are way different with my using the evo maf. My max load I see is about 213 and that pretty consistent with every run

At 5 PSI im seeing load around 130 consistant, unfortunatly i cant see my max load with the changed MAF settings because im getting way too much knock to do a WOT pull

The async accel vs RPM doesn't appear to have the right number of elements as the ROM you sent me earlier, and if that is what it is.... then ya, it's not what i was expecting. Send me your most recent rom?

Also, timing looks high to me. If you're getting knock during a pull, yank 1 degree of timing for every 3 counts of knock, and see if it goes away. I don't know about the high knock when you floor it, but I bet that's related to the overly rich condition created by my heavily suggest MAF scaling....it was probably too aggressive of a change. I think MAF scaling should be marginally increased, smoothing should be marginally decreased in boost, and accel enrichment should be increased when in boost or during spool. I'ma test my rom on the way home with those settings above in the pic, but I won't know a lot until that test.

I do know one thing, the accel enrich table vs engine temp, is certainly in effect for my car. When I'm somewhat warm, I get 10's, after the car warms up, I see 12's, just a general statement...but I think it means I need to let the car heat up more.

That's pretty odd though, WOT 130 load, but can't adjust the fuel map enough to get it near 11.3. I would think with the tephra rom you'd be able to, since the numbers in a stock evo8 fuel map go as low as 7.4 or something.

I'm flashing the tephra soon enough. I wanted to be able to have a point of reference as far as what timing I can run safely at full boost so that I can compare the timing to what I see with the tephra, and know that the knock settings are in check.....but I don't think it's helping me any fighting the stock lancer rom, just trying to bandaid something that may not even be a "real" issue.

My 1 concern though, is that you've got stock evo8 maf values, so does steven, but mitsu and I tried stock lancer, 1 on tephra, 1 on base rom....diff accel enrich values, etc etc, and it's still off. I'm thinking no matter what, I may have the same issues with the evo rom that i do with the lancer rom. The one plus would be more map to work with, but I don't know my max load yet since on the base lancer I'm hitting 96 tops before I start to run lean and let off. I'll give the accel enrich stuff a run for it's money this evening, and possibly be able to safely push higher load...but 130, I dunno if I can hit that. That was my question from the get go on the turbo project, do evo rom's and base lancers record load differently, or is it dependent on maf size, scaling, etc. That's my real thing, is what actually determines load.

Woops, my bad, the picture i posted is from an earlyer version of the "lancer auto tephra V7" rom i had, if you have my ROM/ XML i sent you the other day still, whatever is there for accel enrich settings are what im using, sorry for the confusion! If you need the ROM/ XML let me know and ill gladly re-send it to you. Ill also make MAF scaling stock again to verify whether or not it is causing my knock issue (being so rich) if it is the cause of my knock condition ill just have to take my time and rescale the MAF values until they are in a decent place 100% throttle (around 11.0-12.0 and once i have them in that area using MAF scaling ill mess with the Accel enrichment to see if i can smoothen things out, how does that sound? Alright cool, ill back down timing a bit! Let me know how the settings turn out, im really anxious!

I think you're better off popping accel enrichment in, leaving MAF scaling stock, and swapping out the MAF compensation or smoothing, whatever it's called....then driving, logging, and if you can't get rich enough THEN increase MAF scaling. I think the stuff I posted is pretty mild, so for me it will be a starting point. The thing about accel enrich seems to be that it's necessary to get accurate results for determining MAF scaling. If accel enrich is way off, then it's just going to cause inconsistencies with the rest of the settings. I say pick something, stick with it, try to tune the others, and if it just doesn't work, take it back to the drawing board by starting over with more or less accel enrichment depending, and do the MAF scaling again.

As far as your rom, yeah, the one you posted was old for accel enrich, but the one you have now should be like the one I have in your rom that's on my pc. I say beef that up some, bring MAF scaling back to stock, and see how that goes....carefully as usual. try the accel enrich that I posted, it's pretty "evo-stock" with a bit of adjustment down low, you might like to just try straight eve though, since you said you're rich down low. try

in the enrichmentadj I sent you that I use for scaling.

Also, I'm thinking accel enrich isn't just for the initial stab. Changes to it seem to make adjustments to my fuel settings whenever the car is accelerating....little or big. Like, the entire time I'm pushing through, not just changes in TPS. Confusing table, wish someone had a real good explanation.

I have wondered the load differences myself. Through my experiences I will have to say that load is based off the maf and not the rom. I had the same load readings when I had the actual evo ecu installed and still using my stock maf, then I switched over to the evo maf and my stock rom, the highest loads I was hitting was just shy of 160 only due to the 160 cap that ecuload has. Now using the evo rom and maf I am getting my true loads now. BTW I am uploading a couple vids I just did let me know what you guys think I will post them in my thread

Ok cool, ill make the MAF stock and work on accel enrich settings. My settings now are as follows:

"Async Accel VS RPM Adder"

500-----255 units
1000---255 units
1500---105 units
2000---42 units
2500---18 units
3000---128 units
3500---128 units
4000---128 units
4500---128 units
5000---128 units
5500---128 units
6000---128 units
6500---128 units
7000---128 units
7500---128 units

Is this the right table??

It looks to be, but like I said I'm no expert. Here's why I think I should adjust accel enrich. This is a graph of the 2 different enrichment tables, and it looks like the evo's really kicks off in boost. You'll still probably run lean, just FYI. But at least you won't see that rich knock, and can slowly adjust upward if you want to thick'n her up a bit.

Ok, so i should adjust the values from say 2500+? Also what do you think is up with the random 42, and 18????

I find it strange how much it richened you up by. I have been adjusting my maf scaling a little bit right as I go into boost to lean it out a little but mine is not having that dramatic of an effect. seems like for every 1 I go in the maf I only losed or gain maybe .1-.15 afr points

Yeah it made it pegg rich haha, i have reset it to stock and am going to work on accel enrich, i want to know why there is randomly 42 units at 2000 and then 18 units at 2500 then all the sudden it shoots to 128 units, but then at 500 and 1000 RPM its at 255 units?????

That accel enrich is wrong. It's a different table, don't adjust the one vs RPM adder....I just looked again, and it didn't make sense.

I'm going to just observe, since I'm having a similar issue here.

I never had much luck with the accel enrich tables myself which is why I reset mine back to stock lancer values. I definately see where hornstar might be on to something though. Maybe I have just adjusted everything else enough to compensate for the lancers enrichment settings. Interested to see how it turns out adjusting those values
