Pre-turbo, I did so much looking at LSD options....but even though traction is a bit of an issue at 5-7psi, I don't have a reason for LSD. At 10, maybe I would, 12, maybe...but I know you guys at 15+ especially with built motors and like 20+ practically NEED LSD. Still, I've got no plans to go beyond 12psi, so it's an additional 1k-2k...or more that I just don't think I'll need to spend.

Also...that comment about "i ran 30psi when my mbc broke..............." exactly what I'm worried about, egg-freakin-zacktly...I have my boost gauge set to go BEEEEEEP when i go above 8, which i never do at this point, but...soon enough, I keep saying that, but soon enough I'm going to go 10psi

One thing I really think would be good, ECU boost control, that way if PSI goes through the roof, you could cutt power, drop throttle, fuel cut, all that, and just be safe...but for that, I think I'd need at least an evo boost control solenoid, and possibly an actual evo ecu, depending on if anything is "missing" from our stock ecu....anyone know?

 

I thought they were the same thing. Just the evo ecu has more cache available. And some of the pines are opposite compared to ours. *simple swap in wires*

 

I hadn't heard the cache thing, but the 2 wires, yes. It is possible the pin for bcs is different, but I bet its there on manuals. I'm going to use my multimeter and find out...!

 

I really really need Lsd at 10psi but dont feel like going threw the hassle .

Sucks in traffic !
Anything under 65 i just smoke the tires out , first gear is worthless and second just shoots to redline .

Thats when i was making about 25 whp less also

 

Well it hit so fast that i was not able to react fast enough , my gauge is set to beep at 12psi and right after i heard the beep it was too late and had bent a rod , right after i let off it shoot the rod out threw the block , had a new block in there within 2 days thought !

 

What LSD/tranny setup do we need for are cars, if you weanted to go that route and not spin spin.

 

Well, its pretty commonly accepted that the granny can take the abuse, maybe not the clutch though. As far as spinning, this is the most extensive discussion....so few have gone the route, especially lately.

Please tell me what you guys think:

I re-installed the Evo MAF (399 or whatever). Used Evo settings for scaling, set Compensation to 100 across the board, used Evo setting for "size". Everything else stayed the same basically.

Anyhow, here is what I saw. Car warmed up nicely, good idle AFR's. Once warm, the car would idle at 10.5 or so AFR as soon as I let off the gas, and took it out of gear. It would attempt to lean out to 14.7, and eventually make it there, but not without a few drops in idle and going rich again. This is all with the A/C off.

With the A/C on, when warm the car idles like a champ, 14.7. Once I hear the A/C compressor kick off cause the cabin is cool enough or whatever, the AFR drops to 10, and the car stumbles a bit. As soon as the A/C compressor comes back on...perfect AFR

I tried decreasing the ISCV steps for "a/c off" in the 2 warmest ranges, and that made it worse, idle dropped too low, and the car would actually die. I set it a bit higher than stock lancer values, and it seemed to do better for sure. Rich, but not as rich. Still though, when I sit still after letting off the gas and getting out of gear, the idle would sit too high, like 1100 or something. Eventually, the idle tries to drop to the 750 I have set, and the car goes rich and the idle hikes back up a bit.

Thoughts? Is the ISCV steps not the way to attack this? The car runs butter with the stock Maf, no rich or lean issues. Do you guys think it's a "relearning" thing, where a trim has to get back in check?

Also...injector low and mid trims both went pretty negative after switching maf's.

 

Damn boost leak....thought I was all slick, installing my omni4bar sensor, and tweaking my UICP, so it doesn't rub the hood.

Well...somewhere there, I created a boost leak I think....cause I'm seeing this dip in pressure, with 100%throttle the whole time. HP was also way lower on the exact same road as last time I did a WOT pull....like...25hp lower.

 

HornstartBU how did you tune the ecu

 

Carefully! JK, I used ecuflash, a tactix 2.0 cable, evoscan to log, and lots of help via the tephra v7 rom made by the evo guys.

Here's my new Speed Density 2.0 tune in action, with the stock BOV VTA...going to get a TIAL I think, so it's more "professional".

Loving it! Guess you fixed that boost leak

 

This mother held pressure like nobody's business! It help 10psi for like....i dunno, a minute or so. I left the air compressor hooked up, while I found the screwdriver, undid it, and then didn't realize it was still holding pressure, so that's when it all psssssh'd out.

 

I would like to see how fast the car is on 17psi , any videos you can pm me ?

Thanks
