evo3 with 650s in!! - Team-2G Mitsubishi Forum

matt89 · 07-14-2006, 12:12 AM

well, I just got the 650s in and have the safc at 32- across the board and she runs nice, I dont have a logger so its kind of dumb to be pushing it but I think shes still really rich. It was missing really bad at -25 and I got to 30- or so and it stopped sputtering and started running good, so
I think I'm still okay. The boost is set at 18 lbs and feels quite abit faster than the t25! I think I'm getting a logger next week or so.

Oh god...

This site has been going down hill, do yall dont understand the importance of a good tune. The importance of the right supporting mods. These cars are not toys they are highly technical machines that need to be taken car of and properly maintained.

He'll find out the hard way. Let him play with the afc...it'll just be a matter of time.

the guy at fp said to put the car at those settings and and just drive around with my foot out of it which is what I'm doing. I have a data logger on the way and I'll start getting after it to really see what it's doing. I need to get the thing to a shop around here to get it tuned though. If you could only get one tuning device, what would you get? a wide band or a logger of sorts? can you tune it off of just o2 voltage? it says nothing about your knock sensor or the timing...

crossbreed, what do you mean about the supporting mods, I have about everything you can throw at the car except dsm link and a logger which is coming. If anything, it'll be a good time for a built 6 bolt.

And why the hell is that? Is your motor broken? Doesn't seem like it from your post. So why would you waste 2K+ dollars on a unneeded motor. If your current one is on the outs fine, so be it. But why go and get a 6-bolt for no reason. Change the rods and pistons in your stock motor and it will be just as strong. There is no benefit to a 6-bolt swap unless your 7 took a nose dive into the crank angle sensor. Save yourself money and the big talk for later.

Supporting mods was just a general statement towards all the fu*ktards on this board that dont know how to build there car properly.

Now for you, you defiantly should have wanted to put the injectors in till you had a means to tune your car. You could have ran 12psi (stock boost) on the 16g just fine with the stock 450cc injectors. Instead you are putting you motor in serious jeopardy by guessing how much fuel you need. I seriously doubt that the guys at FP you suggest such a thing.

You need a logger. You can read so much more with a logger over a wideband which is only good for tuning WOT.

as far as i know for us 2g turbo eclipses, is that you want to keep the fuel trim at 0 / 0 for SFT and LFT . I am haveing problems trying to get my car tuned where it needs to be and i have a datalogger but find it difficult to tune when i have never done it before.

If you have the money .. That's the best way to go .. By a 6-bolt, build it, and get it all ready so you can do the swap in the least amount of time ..

Then you can sell your stock 7-bolt as soon as you pull it out ..

thats what the hell hes talking about....its called planning.....good work. Car sounds fun. Peace -Aric

matt89 · 07-16-2006, 08:40 PM

about the 6bolt, yes, I want to have it ready IF the 7 goes south, but yes, when I talked to mike at fp, he said that if I needed to put the 650s in to run those numbers and just keep my foot out of it. now that I'm at higher altitude, I had to go negative afew more because when I went wot the car would start missing badly by about 4k and 7 lbs of boost, but my a/f gauge is bouncing around just like it did with the t25, and I know from playing with the safc and the t25 where it likes to be. too much fuel and you can see the ecu take it away, too little fuel and the safc leans out to the point of all the lights going out. (these were done on the low settings, then for the high, I took the same values and went about 10% more across the board) So I'd lean it out to the point to where the leds stopped bouncing around then would go back up afew clicks so I was about 2-3 clicks from where it would start leaning out, which in the t25 was about -2 from base line with 450 injectors. Now on the 650's that happy point seems to be about-30/-33 by 4k. I haven't been driving it lately just because I DONT know what all is happening, it seems happy, but I know that there is not much difference between an engine that is slowly dying, and an engine that will live a long and happy life. It just sucks that the closest tuner is about 5 hours away.

another question though, I hear that you want to tune for timing on the 2g, but then I hear of people wanting to tune for a specific o2, like 11.0 on pump gas. Is there a magic world where they both exist, because getting max timing out of it might put you in a not so desirable o2 range. So forget getting a wideband?

lol ... Throw that narrowband light show away ... It's pointless.

Your going to need a wideband for tuning, some use a logger, but a wideband makes it 1000x's easier ..

I have like 5 boost leaks that I have to spend saturday fixing, but I was tuning for a 11.6-11.8 afr .. and then advancing my timing until I knocked .. (DSMlink) Some people choose to go a little richer, and advance their timing ... There are many different ways to tune, and I'll have to play around some more before I can tell you the "best" way for me.

-32 across the board.... IS that High and Low -32 across the board ???

2k+, why do that when you could buy a whole 1g engine for 1500 that comes with more than just the block.
