You guys are missing my point, I want to test at sea level to see what the absolute potential of my car is. I know I'd run
12's up here, but I'm curious to see if I can hit 11's at sea level with just bolt ons running 91 octane

 

Hey turbolag, did you ever get that profec installed? I'm considering an ebc and wanted to get your feedback on that unit.

RenoEvo, there are going to be more variables than just elevation in your times, including temperature, humidity, track conditions, etc etc etc. To me, it's like you saying "unless you run at sea level when the temperture is <50 degrees and <60% humidity, you're just messing around at the track." It's not like you're going for the world record or something.

 

Anybody interested in having Al from Dynoflash do a road tune here in Reno? I need him to come up to finish the tune on my car.

 

How much does he charge for a road tune?

 

Maybe... do you know the price? Also, I think I saw you across the street from Double Diamond Athletic Club. Was that you or is there another WW Evo with a bra in town?

i have not installed it on my 9 but on my 8 i had really good results. better spool, no spike , and consistent pressure. the only downside is that on higher gears (4-5), there's a little boost fall off like 2lbs at the most, but i liked having a safety net especially with the higher load on the car @ 4-5th gear. you can fix that with the remote switching sytem that greddy sells, but i rarely ever go all out on the higher gears anyway. if you want i can give you my old settings if you plan on gettting it. it'll save you an hour or 2 of tuning.

 

Has anybody checked out their custom tunes on a laptop? I'm curious to see how the tuners are doing it. Are they raising the boost; while raising the AFR's and lowering timing advance? Or are they keeping the fuel mixtures rich and upping the timing advance? I have a Innovate wideband and laptop in the car and I'll make runs to Fernley sometimes to datalog to see what the car is doing, make a change, data log, etc, etc. I know a lot of the tuners are aiming for 11.5 to 12 AFRs on-boost to about 6500rpm and then they'll fatten it up a little more. But around here on 91 Octane, I've noticed that if running those AFR's I have to retard the timing so drastically that it makes the car feel weaker. Are you guys that are getting tuned over the hill data logging your cars up here to see if you have knock? I've also noticed that the stock boost system has a mind of it's own, and it has parameters that it uses that I don't think the programmers of ECUflash have sorted out yet. You can't control, how fast the wastegate responds, there is no gear dependent control, the boost spikes and then levels off and then falls flat. So I'm debating switching over to an EBC; anybody here have one? If so, does it work better than the stock set-up or is it a pain in the butt to get it set up? Right now all I have done is a drop in K&N filter, a Full Ti catback exhaust, and some suspension work. I'm kind of stuck between keeping the evo and modifying it fully, or selling it and the Ducs and buying either the GTR when it comes out or a '03 Porsche Turbo. I like the EVO for what it is, it's def more stout than my wifes STi (rattle trap) but I find myself longing for that Euro German solidity and less turbo lag. But in the meantime, I'll keep tinkering with it. I've gotten on forums and searched for answers but it's a PITA, you ask a question they tell you to search the forum, you search the forum and you find a 100 different opinions on the topic. So I think us Reno/ Tahoe guys should share our acquired knowledge and actual learned information. I don't know much, but I'm willing to share anything I've learned 1st hand.

 

^^^ Thats a good idea...especially for those who get tuned near sea level, to be able check and adjust our tunes for Reno's altitude. The problem is that when you frequently are changing altitude it becomes difficult to maintain a good tune 23psi sea level is not the same as 23 psi at 4,6,8000ft elevations. It will burn less and less fuel the higher you go(in turn making less power and running rich)....Dustin, do you wash your wifes STi at the Double R car wash, if so, I think we met.I had the white evo, me and Renoevo were waxing his black evo.




Anyone have a stock intake snorkel and top of there air box they want to sell?

 

I have a Jestr mail-in tune and it appears that he's leaned it out a bit while raising boost and changing timing. At WOT, I'm at 11.3 AFR with 23.2psi of boost tapering to ~20psi. I get around 2-3 counts of knock when the boost kicks in ~3500rpm and also the same knock at ~7000rpm. I'm hoping to dial-in the tune this year on the track to squeeze as much power as I can with the current setup, then maybe go with a big turbo upgrade over next winter. I believe you want to be 11.0<AFR<11.5 to be safe. It seems that a leaner AFR doesn't net as much power as the safety you're trading off. I'm currently using the stock BCS with restrictor pill removed to control boost, and mine seems to be pretty consistent. However, I am considering an EBC to have the low/high boost settings and minimize the taper.

If your priorities are just speed, stick with the Evo and mod it out. If you want a mix of speed and status symbol, go with GTR or Porsche. But don't be surprised if it gets outperformed by a modded Evo.

 

Yeah that was me... wife has the black STi.

 

You're running 23psi? Did you change out your head studs and gasket? I hear the stock head studs will stretch after awhile with anything over 20psi. I can get the stock BCS to boost to 26psi and taper down to 20psi but I keep it at around 19-20 psi right now because I haven't done the studs yet. The only thing with the stock set-up is that it's hard to set the spool-up rpm range. I've been screwing around with the "Boost Control load Offset" numbers to see if they make a difference... Stock, the car is told to max the load at around 219.4; when it goes over those load cells the "Turbo Boost Error Correction" table lowers the dutycycle to bring it back down or if it's under those load cells the table adds dutycycle to bring it back up. If you raise the "Boost Control Load Offset" #'s the car will then go above the 219 load area without dumping the boost; but I'm still screwing around with it to see what all it does. There are some other parameters too that nobody seems to know what they do; "Boost Enhancement Start RPM (anti-lag)" , "wastegate Solenoid Activation Rpm", "Boost Enhancement Stop RPM", They all sound interesting but I have yet to find anyone that knows exactly what they do.

The EBC seems like a KISS (keep it simple stupid) solution, you can control the boost exactly how you want and you don't have to bother with trying to figure out what the hell the car is trying to do.

 

lol, thought i was the only evo owner that used that one....i was just there friday. On the topic about Al comming to do a road tune, Id be interested, but there are some questions that should be asked before he is asked to come. Price, date, how long will he be here, and has anyone here in reno had Al do a road tune? What were the results?

 

gobagheera,were you in north carson this morning?It looks like your mr

 

No need for studs or hg at 23psi. There are many people running way more than that stock for thousands of miles with no issues. You just have to keep the detonations in check.

 

Yeah, that was probably me. I didn't see you...
