So do you need to add fuel for higher boost levels? Or does it just depend on bolt on's and such?

 

[SpeedAdiction20]

depends, but based on the supermap at least up to 10-10.5ish psi, I've just needed to take the fuel away, generally in the same rpm ranges as in lower boost levels, at least with boltons, I'm guessing once you go with the bigger turbo/injectors ect.. it's a whole different thing, but ya the whole map is crazy rich, but I usually keep it around 10.5 to 11 afr at the very top rpms like around 6.3-6.5rpm, some where around that, just to be safe at the high rpm since I figure I don't plan to need that little amount of power at such high rpm

 

[Ricktalife]

Okay sounds good. I have noticed like many have said before that in the higher RPM's it does lean out a bit so I'll have to figure out exactly where so I know where to stop taking fuel out.

 

[SpeedAdiction20]

ya, you'll notice that it leans out, but not enough to actually have any need to add fuel, but just do a couple sets of data logging and just find the general large areas where it is really rich and change that section, and then do a few other runs data logging with the changes, and go from there, if there are sections in all 2 or 3 runs that are rich or lean, than change those, but you'll find that if you dwell on all the little cells that are maybe a little to rich or too lean for a split second, than you'll go crazy, I tried that when I first started out and found I was spending hours and hours on it, and end up screwing it up in the end, keep it simple, make some major changes with the problem areas, than do a few other runs, make sure your generally happy with the changes, than come back another day and do some other runs and see if you need to edit it.. I also find it helpful to keep the general temp. that day in the notes section so it records with the each data log run

Some good tips. Thanks man. I'm talking to an IT guy at my work to see if he can take a look at it and throw me some advice as well.

Hey guys, ive been going up to the mountain lately and on the way up my car runs like crap. My car runs good in town on the flat so why is it having trouble going up hill. Im posting this on this thread because Im thinking that going up hill is going to require more fuel to be delivered(its running lean up hill by the way) and that the ssafc is preventing the ecu to adjusting to going up hill. So Im thinking that Im gonna need to run a richer map every time I go up. Let me know what you think.

 

[Ricktalife]

How much gas was in your tank? Just curious.

What is the elevation "in town" vs the elevation "up the mountain"? If the change in elevation is several thousand feet it is reasonable that your car would run differently, and the more fine your tuning is the more you would notice it. The air gets thinner as you go up so the A/F ratio that is perfect in town may be way rich up the mountain. My dad used to have a '75 Toyota Landcruiser we went hunting in. We live near sea-level but were hunting at 5,000 feet elevation. He would retune it each year right before hunting so it would run crappy in town but purr up on the mountain where dependability was more critical. When we got back home he would re-set it to run right there.

Half tank, im gonna try to not go below 1/4 tank since I put my new pump in.

The peak elevation of the mountain i go up is 8600 ft(but I don't go all the way to the top in my car) and in town can go down to 1444 ft. Yeah I was thinking of that on the way up to but forgot about it at home.

 

[SpeedAdiction20]

my only guess is that if you have it tuned pretty well (leaned it out) around town, than it would be lean further up, but if it's something like the stock supermaps that's rich anyways it shouldn't be lean either way for the most part I would think..other suggestion would be to just stay out of full boost or any boost if possible, or at least just keep a light foot on the gas to gain speed slowly, ssafc wouldn't change anything out of boost.

oh and also I just thought of something else, you could increase your "over pressure" settings to something like 3-4 or something like that if you like and just stay below that amount of boost going up the hill, at least for the time being, if your going to be going up the hill all the time, than that just sucks.. but also just saw you have the 565 sti injectors with no raised boost or diff. turbo or anything like that.. my bros car only has the 440s wrx ones and his ran like s*** most of the time and he has a very built engine except for the actual rods/pistons, (had unichip but took it out because it just wasn't working well and couldn't get anyone to dyno tune it around here with his mods) but I dono, what to say other than that..maybe someone else with more experience with the elevation and the large injectors will speak up..

 

[Ricktalife]

^^ I think those are some good tips, especially the over pressure.

just got my ssafc in today, kinda nervous about installin it though. i have a buddy who put a A/F ratio controller in his miatta that is going to help me put mine in. his is a RC controller i think.

 

[HondaEat-R]

It's no problem to install, especially fresh. Just take your time, and go by the ECU Pin-out # over the wire color, because I think there was some variance. Don't do cheesy crap, either solder or good quality spade connectors (what I did). All I can say is don't rush it. I got pissed doing mine (had to clean up Emanage mess) and punched a dent in my car. I'm that guy. Good Luck !

just noticed that post count 606 is repeated half way down the map list, I think you meant to add the other map I loaded in on ..http://www.msprotege.com/forum/showthread.php?t=123620555&page=69
this page.. my summer map one is actually not bad, I had a small leak but it works well under normal conditions, would just need some changes, but a good base map to start off on, just figured I'd let you know Wagon, thanks

now time for me to go out and do some tuning myself, gotta tune for 10psi all over again b/c the one now sucks, very slow build up on the Greedy ebc, hopefully it doesn't take tooo long

 

[Wagonbacker9]

rectified. added one more that I found as well.

ive gotten a few runs in over the past 2 days and im getting 10.0 at wot. the temperature is about 65 degrees here. when the afc was installed last august i got consistent 11.6 at wot. obvisously it was hotter then. is the 20 degree difference enough to mess with the afr's like that? im running the supermap at stock boost if that makes any difference

no, somethings backwards here. typically the colder, the leaner. Cold air is more dense. So if you have the same amount of fuel coupled with colder air you will run leaner. no?

 

[SpeedAdiction20]

EDIT:^^^ no other way around, colder it is, the richer it is, I believe since the ssafc doesn't adjust to temp. just the stock ecu, or something like that, but the more air comes in, maybe the MAF over compensates I guess and throws crap loads of fuel in there.. could just be bad stock tune/map from mazda to begin with at colder temps I think..

first off.. thanks wagon, I wasn't too sure if there was another one also

and also the theEZV after tuning a little bit today (couldn't too too much, I had just gotten a much better setting for 10psi on the Greedy ebc than I had before, I think I might need to tweak my 8psi at some point too.. and the fact that at first for a while there was a cop posted at the end of the straight away where I like to do my tuning runs lol)


but after doing a few runs, I realized that I forgot to add the coefficients into the datalogging for the wideband as well.. but I got 3 runs, the first 2 just to see what is was like on stock supermap, and the last one after I changed a small value up top.. but my point is that I was really confused because every single other time I have tuned and the last couple weeks at least at 8psi, I was running crazy crazy rich even when it was warmer that it is now. and I get the setting for 10psi finally and it's almost too lean in some areas. I'm going to have to add fuel to the supermap which I've never had to do what-so-ever, so I was a little confused, so as of now, I am going over the data logging and making some notes and changing a few areas that need to come down closer to 11.5 instead of 11.8 or so in the high rpms (I stop at redline/ 6.5k rpm)

which brings me to the conclusion that since my 10psi settings for the Greedy were so bad and lagging and now I notice a much better response and I think I can improve it more at some time, is that just the settings difference and how it controls the turbo and wga plays a huge role in the maps.. when I get more time soon I will try to do some logging at 8psi and see what is going on, and screw around with the Greedy ebc settings at 8psi and see if it changes it..

more related to your question is that I guess so.. I am going to have to see if it changes in the next couple days at 10psi if it stays warmer, and then check to see what happens at 8psi.. but it's 65 here also.. so also do you have an ebc. or have you set the boost to anything different?.. also if it really was around 85-90 it would be much lower afrs at WOT compared to now, I wouldn't expect to see 10.0 all the way through the power band but in a few large chunks, yes..

should be interesting if I figure out a way to set my ebc to make it have a much better response than before, and somehow have it improve the afrs to some degree.. I dono how but oh well.

oh and also I should mention that the other week when I was getting really rich readings at 8psi, my EGR valve was really dirty, I cleaned it really really well, so I think that is having a large effect on the afr.. .theEZV I would try cleaning your EGR really well and see if that improves your afrs I know it made my car sound and run sooo much smoother and really open up instead of it kinda stuttering/sluggish and really rich

..edit2: also after looking at the data log runs for about an hour, I find it strange that after the first 2 runs between cells 9.5-10.5psi (remember the ssafc switches to the next highest cell once it hits half way, so that at 4.6k rpm and 10psi or so, it will be on cell 5k rpm 10.5psi, it took me quite a while to grasp that, and it still is confusing sometimes) but anyways, 9.5-10.5psi at around 3.5k-4 or 4.5k rpm it is really rich, like in the low 10s, but when I changed maybe a small setting on the ebc to lower the end boost to around 10 or lower, and changed the "over pressure" to -1, the last run I did, the afrs were around 11.5 or so around that whole area.. I don't get it, but I just need to do some more runs to check for patterns.. other than that I am just adding some fuel to the very beginning, where there is low rpm but high boost at the start, and than again at high rpm and high boost for safety.. hope it stays consistent on me for once.
