stock injectors. You know what imma try dropping my injector scaling and see if it works. I hadn't tried that yet. Thanks 03 lance. Imma try it right now on the way home.

 

Strange then with the stock injectors. I dont have any experience with messing with the stock injector settings I installed my 440s during my intial turbo install.

 

yeah I hadn't sent mine out to be cleaned yet and didn't want to risk it. Plus I barely understood anything with ecuflash or injector scaling so didn't want to add another variable in to the equation.

 

Attached is another log with the injectors scaled down and the stock MAF table. This was better with normal driving it wasn't leaning out like it did before with the initial stab.

It definitely didn't get richer or any of the map AFRs while in boost.

 

Okay, so if that's 5psi, then yeah, it's not too happy being so lean. The knock that shows up is probably from getting too hot, although it ought not happen so fast. Either way, the fuel isn't showing up, which means the fuel paths aren't doing much. I think with the stock maf values, you should try each of the paths again, just to see, and post a log of each, like just 1, just 2, 3, 1&2, 2&3, 1&3 basically, then we can ask roadspike about it. Be careful not to run through boost being all lean like that, but also you can't get a good test if you just punch it and then let off instantly.

 

ok, I'll try that. Yeah I let off cuz I saw the knock.

We can put this down as Path 1 set to 0x9.

 

off topic but can I get an OMNI 4 bar to log boost, or I can't do to not having an Evo ECU?? Is there a boost gauge that can be logged??

 

I believe you can use it to log boost fine. You cannot do boost control without the evo ecu. Someone correct me if im wrong though.

 

Ugh, that blows you're still having fuel problems. I'm considering going speed density. I'm ready to make some damned progress. This is nuts!

 

green bandit thave u tried any of the fuel paths yet. And heah I want to go SD too but its going to have to wait till next year.

The only thing I'm worried about SD having this same issue. Only auto of I know that has done so is Mitsukid but he has disappeared.

 

he wasnt the only one he did it after i did the testing for rs lol
and i didnt have any fueling problems with sd that i remember

 

sweet. So that gives me hope for when I go SD.

So there were better results today with the different injector scaling. The car didn't go lean while in closed loop, it did at higher loads but Imma try the different fuel paths in the next couple of days and if none of them work I will start playing with the fuel maps.

 

ok I'm going to try path #2 on the way home right now.

Can someone clarify for me though when someone would have to scale their MAF. I been reading the thread over in the evo forums but I'm all confused on when you or why you need to scale the MAF.

 

The MAF scaling and compensation tell the engine how much air/fuel is/should/might be going into the engine. If you replace an intake, the air coming in might get monitored wrong, so you'd potentially have to increase maf scaling, so your idle trims don't get thrown off so much. That's for the evo though....

For the lancer, you are basically telling the car to pump more fuel out. Here is the thing, the stock lancer rom, with either an evo maf and scaling or the stock lancer maf and scaling....is going to run lean.

The Evo ROM, with either lancer or evo maf...is going to be a lot more solid in boost. Fuel gets there when it's needed, and all is well.

So....using MAF scaling to make the fuel get there on the stock lancer rom just isn't a solid solution. I think what you should do, is set it all back to stock MAF scalings, put the fuel path 1 in, turn the AFR Map values down in the "boost" area, and see how rich you can get it. If the values logged by AFR Map don't go lower than 10, tell me. Try decreasing the values in the AFRMAP though, lower than 10, it's just a value...not an actual thing, it's relative so it can be reduced to say ...10, or 9, even if AFR is 11 at that point.


Oh, and Speed Density, you can adjust how much fuel is there per load using a table called KPA vs Load, so you can get fuel where you need it. That's why those guys didn't have trouble getting fuel there on SD. Also...it's kind of possible that MAF compensation might be a good table to adjust in lieu of a solution via the fuel paths from roadspike. It's more...well, it's a different part of the fuel equation, and it doesn't make the AFR's "spongy" . You can actually tune speed density using that table, and leaving kpa2load stock, so it's possible it can be used to iron out the maf scaling.

 

oh no I wasn't thinkkng of using the MAF tables. I was asking more for knowledge.

I put path 2 on today when I left work. I'm giving it a full day just like I did for path 1. Path 1 was fine at the beginning and then it started going lean.

SD it is next year. My xmas present to myself will be getting the 440s cleaned and flowed tested. so they'll be all set when I go SD.
