log advise


Can someone take a look ? I don't have much knock (.4 ) . I gave it some timing( 1-2 degrees ) . Afrs are pretty good . Car runs and idles good . I'm just looking for a conservative tune . Is 1 degree of timing worth 1 degree of knock ? I gave it 1 deg at 6000-6500 rpms but it caused 1.1 of knockret on the dsmlink so I took it back out . I added 1 deg at 4000 then 2 from 4500-5500 . One on the slider and 1 on the graph . Do you guys add timing any lower than 4000 rpms ?Thanks

I'm not an expert but I'll look over your log when I get home from work... You add timing at low RPM to faster spool smaller turbo's (like your 16g), just create a dip in the sliders where you see it knock. It sounds like you've got a decent WOT tune on it, now its time to do 25% and 50% and 75% pulls (like freeway driving) and use your DA maps to make adjustments so it goes in and out of boost smoothly.

When you let the ecu pull timing by riding the knock sensor, it pulls too much timing and degrades performance than if you would have tuned it to no timing retard.

Is it pulling timing at .4-.7 or is that a knock count ? I thought the ecu doesn't pull timing untill 7 counts of knock .I have my cel set to come on at 3 counts and it hasn't . Thanks

Heres what I suggest...

Fuel-Fuel sliders are only applied at WOT, your adjustments below 4k are pointless and if you ever do go WOT that low in the RPM band you'll bog because your +15.6%. You really should just zero them all they way to your negative percentage at 5k and make it a smooth transition. What octane fuel do you fill up with?

TimingI suggest putting your timing sliders at zero and getting your fuel AFR's where they need to be first.

MAFCompOnce again SMOOTH transistions on your MAFComp sliders, these are one of the most important things to set correctly so you can tune your car the best that it can be. They shouldn't look like a mountain range going up and down like yours, nice and smooth.

After you get all the above taken care of do a pull in 3rd gear from 3k-7k and post it.

I agree with Gofer but I'll add the following:

Something isn't adding up with your target AFR, WB, and MAFComp. It looks like your global fuel is off (and your deadtime looks low for 650's, but who knows). I don't see logged boost...how much boost are you running?

Your target AFR's are in the low 10's and upper 9's based on the stock DA table and fuel sliders, which is pretty rich. You are running a bit leaner than that, but I would expect you to be quite a bit richer based on the 650's, injector duty cycles up around 80%, global fuel setting being rich, and the MAFComp sliders all being adjusted to add fuel.

Here's what I would do:

1. Double check all the mechanical stuff and get it right (boost leak test, base timing, exhaust leaks, etc). If you have any mechanical issues, you will be chasing your tail while trying to tune.

2. Calculate your global fuel pressure based on the fuel you are running, base fuel pressure, injector flow data (if you have it), etc. Once you have this set, don't touch it again unless you change the fuel system or type of fuel you run.

3. Zero all the sliders, lower the boost to about 12psi, and get your MAFComp dialed in. Take your time and work on it until fuel trims are in line and your WB reads very close to AFRatioEst at WOT. It also wouldn't hurt to change all the values in the DA AFR table (OpenLoopMaxOctane) that are 10 and below to something like 10.2. Anything below 10 is just way too rich and makes dialing everything in a lot harder.

If you see knock at any time during this process, use the timing sliders to pull a degree or two at the offending RPM and try again. The idea at this point is to get everything calibrated without endangering your engine...not to make power.

Once everything is lined up as described above, you'll have a good foundation to start with. Only THEN are you ready to start tuning by bumping the boost a bit (and re-calibrating the MAFComp at the higher points you will be hitting), adding some timing, leaning it out, etc.

Thanks guys . I wish there was a tuner around here , I just want to drive my car . Every time I think I'm close someone reminds me that I have no clue what I'm doing . Car boosts about 20-21 psi . It came from dealer that way . Dsmlink had to be changed so the dealer did it and just set the globals at 25.8 because they didn't know . It was so rich it made your clothes stink . I'm at 28.9 with the global . The injectors are the only thing I'm not 100% sure of . The dealers add said 660s and the mech told me sti 650s .650 is scratched in it with a dremel . Evo8 fuel pump . Is it safe to drive like it is ? I'd like to go for a ride . Thanks



93 oct fuel .

Chart says I should be at -31.9 on my globals 180 dt. I just question my injectors and was trying to be safe . Like I said at this point I'm just trying to get out of the garage . I'd rather be rich . Maf comp is like a mountain at low end , I smoothed it out a little but it was pretty extreme . If maf comp is going richer on the bottom is it ok to take more fuel away with the globals ?

I know I'm looking for 10.9-11.0 from 4000 rpms up wot . What am I looking for at lower rpms ? Or say half throttle . Does the computer set afrs at cruising speeds once maf comp is dialed in ? What is a good cruising afr ?

I think I'm making progress .I reset fuel and timing to zero ,set global at -31.6 and started adjusting maf comp . I think it's pretty close .Boost est reads right now ,Afrs are close , a touch more at 1900+ and 600 . No mountains . 800hz could use to go 1 leaner but I don't want to make a steeper point . Anyway thanks for the help , I learn more everyday . Here's the latest log . I'm on hold for rain .Thanks

With global fuel, base pressure, and deadtime... you are modeling your injectors and fuel system. In other words, you are telling the ECU how your fuel system is set up and how much it flows. With MAFComp (or VE table if running SD), you are modeling your intake airflow; basically telling the ECU how much air should be reaching the cylinders at any given time.

Neither of these should be used to tune with. They should be dialed in as closely as possible to reflect your engine's airflow and fuel system. By having accurate data here, it makes it easier to tune the engine by changing the target AFR or adding more timing.

BTW - Getting the airflow model dialed in (with MAFComp or the VE table) is by far the most time-consuming and sometimes irritating part of tuning IMHO.

*******************

You are definitely getting closer. You still have a bump on the 4000 RPM fuel slider, and a corresponding dip around 800-900hz on the MAFComp. It's minor, but still...

What version of Link was that log pulled on? It looks like you are still using the old AFRatioEst that requires the proper variables to be accurate. I would download the latest version of the app and firmware, in which AFRatioEst is easier to use and IMHO more accurate.

How much boost are you running now?

MAFComp is still off a bit up top; target AFR is dropping but your measured WB is climbing into the 11.2 range. Also, it doesn't look like BoostEst drops off quite like it should as the engine's VE drops at higher revs. It actually climbs and levels out at about the point I would expect to see a gradual falloff.

You could also go ahead and change the remaining DA AFR cells that are below 10 to 10.2. Although it doesn't matter a whole lot, if you hit a "border" cell, the ECU will interpolate between the two values.

Ok here's the latest log . I think I'm close ,car runs good . Globals are -31 and 195dt .I took out A degree of timing were the couple little flashes of knock occured ,didn't get a new log cause it's now raining . Taking back out what I put in . Little blip in fuel slider I just had to lean up a little in between maf settings .Everything looks pretty good . Boost est is 20-21 on top ,that's right . Car pulls good ,actually goes like a rocket . I can't image if a real tuner tuned this car . Anyway I'm pretty happy , I think it's safe to drive . Let me know what you think . Thanks again for all the help .

Give me a sec something is going on .

I don't know . Now it says I've alredy attached it so it won't let me do it again .

Well here was the second to last run . I dropped my 0-50 hz levels after this and got the ltft to + 1.20 . I made a couple small adjustments but this is were I was headed . Thanks

And raised my dt to 195
