Heres one thing to keep an eye out for too....Make sure all of your exhaust connections are tight and leak free before the WB o2 sensor. If you have the tiniest exhaust leak your afr's will start showing up leaner than what they really are. I started freaking out when i went from 10.5 at boost to 13, and then realized the downpipe was loose.

 

Thats a good point but so far so good although another member on here was nice enough to send me their rom for me to compare and looks like I have alot of things to consider and change around. Man this stuff is confusing. The main parts of timing adjust afr adjust I get but this maf and injector scaling is just killing me

 

Ok this might be a dumb question but. The stationary rev limit, is this what we can use to set a launch rpm?

 

Yes, but only with the Evo ECU and the clutch pedal position wire mod.

 

Injector scaling should be first. Did you replace your maf? I'm too lazy to go back and read that far, but if you didnt, then you shouldnt have to touch maf scaling. Thats for if you upgraded to a 501 maf or something. The stock maf should have no issues with a mildly turbo'd lancer. Injector scaling is another beast, but i remember reading in one of those sticky links you had that its just a matter of plugging in the conversion #'s for voltage and CC's, and then minor tweaks from there. YOu shouldnt need major tweaking. As for your Timing and afrs, try keeping your timing only advanced a degree or two, during boost and high load, and tune your afrs to match. Once you have a good tune, then you can start advancing the timing a degree at a time, readjusting your afr's, and checking for knock counts.

 

Yes I have a stock maf, as far as the scaling I didnt adjust the scale but I upped the numbers in the right column quite a bit and this allowed me to bring my injector scaling to 412 with trims in the -1 -2 range. So your saying basically from the 3000rpm, 70-80% load and up range I want my timing numbers around like 1, 2, 3 range? Is it ok for mine to be higher if there is no knock, cause from my reading you want to advance the timing until knock is encountered (assuming you dont have access to a dyno) this should give you close to your best torque right? Or will I get more power with lower timing up there? Not tryin to have the answers handed to me or anything, I have read. I have over 150+ hours of just reading how to build my kit (when I started this build I thought a wastegate and BOV were different names for the same thing ), installing and tuning. trying to figure this out. Zulu's professional tune brought him to 180hp @5psi. I did a vdr run and came out to 130hp and 161trq now dont know how accurate this is but gives me a ballpark and so I have some work to do for sure. Another note, for our target afrs of 10.5 or so does this apply to just full spool? Or are we trying to acheive this during the spoolup time as well?Thanks for all the help I would be with out you guys

 

10.5 AFR is pretty conservative. I shoot for 11.0-11.3. You would like to achieve these AFRs whenever you are in boost (partial boost or full boost), whether it be WOT or partial throttle.

 

Ok cool so I just did a 3rd pull to little over 6k afrs at 3k were still 14.1 but dropped really quick by 3500 i was at 12.5 and by 4k i was at 11.2 and dropped down to 10.2. I bumped everything from 4500 and 80% up about .4afr gonna see how that works. Now my timing from 3k on starts at 6 with no knock so I am going to keep advancing until I get knock.

 

yeah 10.5 is a conservative number. Its what i was running without a tune. 11.0 is a good number.

As for your timing, i'd say yeah, you can advance the timing, but first tackle your afr problems. Back the timing down, work out all of your tuning issues, and then once you have that solid, you can start to advance the timing a couple of degrees and retune.

 

Ok I decided to bring the timing up average 2 degrees along with the .4 afr increase gonna see what I get there. If my afrs are closer to 11 I might leave it there then continue with timing until I hit my limit then retune afr if needed. I remember in the sticky how to tune an evo he recommended tuning timing first then afr but not sure that applies for us since when we go turbo we have to lower our afrs just to go into boost safely, or at least i did.

 

same thing i did. runnin pretty good as of now. ill get back to it towards spring, since winter is coming here in wisconsin and its time to get out the snowboards again

Now I know vdr isn't completely accurate but I have been doing pulls after every adjustment and laid it in vdr. For some reason when I advanced the timing those 2 degrees I went from 144hp to 128?? very little knock not sure why? Gonna drop it back down and see what I get.

 

ive had troube with vdr myself. do you have an iphone or ipod touch? they have pocket dyno for that and to me it seems fairly accurate.

josh

 

Nope I have the storm. Lol actually its what I'm in now here at work haha. I don't think its vdr but I could be wrong I will find out by moving back to my previous flash and see if I can duplicate the results.

 

i think that mite b a better choice, bcuz if u can duplicate it then u know u did something wrong
