Question Small Question about 0+downpipe

Hello,

Just installed my Xede today and uploaded a 0+Downpipe 93 map.
First of all , is there a way to fix those damn access violation messages ? I did a few searches on the forums , and it seems these errors were related to the use of an older version of xmap. I use the latest version , with wich its supposed to work perfectly. I tried on a laptop with usb to serial port , and experienced quiet a few problems , then i switched to an old laptop with a serial port. It was way faster , and it managed to work after a few dozen tries. Took me about 2 to 3 hours to manage to upload that damn map. If you guys have some advice to share in making this damn software work well , i'm interested.

Now that the map is loaded , i saw i have quiet a noticable amount of white/grey smoke coming out of the exhaust when starting the engine/ starting from a stop/redlight , it's less noticable when i get higher in RPM . I'm no tuner , so i don't really know whats going on now , so i'll dig in your knowledge if your ok to help me out on this one.
I ordered a stage 1+ sig , but won't get the cams & gears put in before mid Jan i think , as my mechanic is away atm. I'll then enjoy a nice afternoon again cursing at xmap i guess.

Thanks in advance

Make sure you only have xmap 2.0.1.1 downloaded on your computer. I have seen some people have trouble when x-update, or the older xmap is still installed.

How many miles have you put on your exhaust? A brand new exhaust will have to burn off the oils, and cleaning solutions that we use when building it. Also, if you used any WD-40 when installing it, that will cause quite a bit of smoke over the first 1 or 2 heat cycles.

As far as i know the 2 pc's i've been using didn't have any older version of the software on them , as they weren't mine. I don't think my mother has been secretly tuning cars with her comps

Exclamation

about the white/grey smoke now ,
i just came back from the Dyno , and I had the time to notice a few things about the smoke.
First it smokes a lot less now when i start and at low rpm. It did however leave a white mark yesterday though in the exhaust tip. I guess it kinda "purge" itself now as it smokes less.
On the dyno i saw it did smoke a little under load.
I'm runing a dump back signature exhaust with a test pipe , so i didn't really expect it to be crystal clean nor to smell like a flower from behind. I had the exhaust put on on Friday afternoon, and drove till yesterday with it , it didn't really smoke white ( used to smoke though but hey , catless i guess it changes a bit to remove a filter).
Yesterday after installing the xede with the mentioned map, i had the smoke problems as well as iddle probs , car just went very low in rpm at iddle after a stop , stalling a few times. I have a VTA BOV and i'm used to stalling sometimes during a stop, but not going so low in rpm at iddle nor stalling so often. I checked the forums and saw i could have mistaken the boost wire with the iddle control wire. So i figured i'd check this again this morning. This morning i didn't get the time to do it so i had to drive a few miles like this. Car felt good , no more iddle problems , a LOT less smoke ( i mean i didn't leave any cloud when starting from a stop ) , so i don't really know what happened. I checked the green wire and its the good one.
Back on the dyno then, few amounts of white smoke , but the main worry is the smell , it smelled gas quiet strongly.
I don't use the stock airbox, but HKS RS intake, so i suspect there could be some problems related to the fuel map with this intake.
Question is :
1. Is this dangerous.
2. Can i drive this quiet safely for a week ( without pushing it too hard ) until my laptop comes back from europe.
3. What should be changed a bit in xmap to "fix" this problem when i get the comp back ?

BTW other than this prob , car feels great now, great improvement. Here are the numbers ( our dyno is an italian one from DIMSPORT).

Stock evo 7
232.6whp
254.57 tq

With HKS RS intake
238.4whp
260.9 tq

With dumpback signature exhaust + testpipe
266.8whp
249.04 tq ( lower than before but didn't fall after 5700rpm , was pretty much flat from 4200 to 6600 )

With xede runing 93 octane stage 0+downpipe
257whp
271.01 tq

On that last dyno run the numbers in HP are lower , but accross the board it was better , reaching peak hp at 6900 rpm and not at 7500, and hp&tq curves being on top of the previous ones all the way to ~7000.

I'm not really interested in pure numbers , i'm more interested in seeing how much gain i get from some part or the other. these numbers may seem low/high depending on what you think of the dyno , not sure you have those in the US.
We have only one here so heh , not so much choice anyway
200$ a dyno run too, i'm curious about results but hell i wont ask the guy to make 20 runs each time i come , that would be pretty fking expensive


Thanks in advance,

Id say your main problem is your VTA BOV and you HKS RS intake.
As well documented on the forums they lead to a rich condition, which is prolly why your smelling gas.Unless your custom tuned for these extra items your car is not going to run at its full potential and will have the symptoms your having. I dont even think you can tune for the BOV unless your using a standalone EMS. As far as having the wrong boost wire hooked up, if that were the case you would not boost more than 11 psi.

Welll i guess the stock airbox got a bit broken when unscrewing the AF mater :/

So if you guys think i'm runing rich, what about the danger of this situation ? Runing rich for 1 week i mean.
I can always lean things out with xmap when i get my comp back, but it'll have to be aproximate as there is NO wideband in the country. I'll have to buy one. Here on the dyno they just strap the car , go in 4th , floor it then hold out their hands for the cash.
So if you guys have an idea of how much i should lean it out, or if its still pretty safe to drive like this for a few days. Nobody answered that question , and thats my primary concern now

Rich is not going to hurt your car, Maybe foul out your plugs and make it stall out at stop lights.
Rather than hand over your cash for some half assed dyno time, just find yourself another stock airbox, ditch the BOV and your tuned.
Simple as that.

BTW...I would not lean out anything towards approximate.

TY
I'll try to find a stock intake but it may be a bit hard to find a 2nd hand one, as there's few evos here, only 3 in fact, and the dealer here is a nice crook.
He offered me 1600$ for a 10.5 hotside, changing brake pads would cost me 990$ all of this without labor , etc ... So i guess a new stock airbox would cost me a arm and a leg.
Everything is damn expensive on my island , hell i even paid my car 50k$+ 2nd hand.
I'll try to see if i can change for a Kansai service carbon airbox , as they seem to be pretty similar to the stock one.

What does it cost to ship stuff from the US or Jpn? would that be a cheaper option?

(I had to look up where New Caledonia is. TGFG)

Cost around 600$ to ship my stage 1+ from vishnu + 39% import duty on goods+freight.
Shipping from japan is pretty fast & cheap , those guys are incredible , you ask for a price on thursday , they give it to you on thursday afternoon , if you pay quickly u get the goods by monday morning.

I'm used to import from overseas but sometimes for small amounts its just too much time consuming and i can't afford that.

If you're strapping your Evo onto a Dyno, what about your A/F ratio? Don't they have a wideband O2 sensor? If they don't, I'd seriously think about getting something like a Innovate Motorsports LM-1. Not only will this allow you to monitor your A/F ratio, but when version 3 comes out for the XEDE, you will also be able to log A/F

At the state of tune that you are currently at, I'd be most worried about fluxuating A/F ... running too rich wouldn't worry me too much (although you're losing power there), but I would be worried about running too lean. Lastly, and this may sound silly, but if you still have your stock airbox, and it's cracked ... just superglue it. It's just plastic and doesn't have to hold an excessive amount of pressure.
