Well thats the thing. If i spend 200 bucks on a good bov and it works, then sweet. If i spend 200 bucks on a bov and nothing changes then i might as well have spent 200 on this stuff and potentially tune out the issue.

Does this stuff have a chance at ridding me of my problems or would i be better off spending the money on a quality bov?

that's what happens when you hit multiply instead of divide and don't pay attention

it didn't like fill the cylenders with gas; just stalled out due to richness.

no fear.

New XDF: http://dl.dropbox.com/u/2074311/Volv...-beepee-v9.xdf

better categories, lots of small fixes, swapped some table axises(sp?) around to make them consistent.

also found the idle table that switches with A/C compressor status

a few more comments as well... check it!

I've still got a recirc; couldnt tell you.

If we can identify more tables and data then there may be a work around. No promises right now.

If I stay with a AMM setup, I'd just buy a recirc valve. Unless you are at some crazy boost level that needs a BOV? Is there even such a thing?

I understand runing the extra hose sucks, but what's the big deal about using a recirc? Why does everyone prefer BOV? I'm dumb, explain.

Recirc works just fine, keep the air and hoses near the turbo, not the throttle plate

Sounds like it. I need to pull my current setup out from underneath the covers and start watching it again...

Sounds like there's a problem THERE, not with your BOV. I know you've dug into that before though, so... Dunno man!

Suuuuuuuuuuuuure, right after I spend the last hour playing with the v8 one. I tinkered with a 935 NA bin to my liking for a starting point, but now that I've done that I need to clarify that I can even run a 951 computer with a 935 bin! I'm thinking not, as I can't open and look at my 951 bins properly using your 935 xdf, which would lead me to believe they are looking at different locations for some of the same stuff?

Does anyone know if I can run a 935 bin on my 951 computer? The other option will be to download a 951 xdf from elsewhere on the netz(pretty sure I can find one) and tweak that. But it won't have the awesome Beepee notes and such!

Ps. BOVs can be cool because they make more noise.

I'm running the 93x turbo rom in my 954, so you should be good.

not as much cool stuff, apparently the ostrich I've borrowed doesn't allow for tracing.

Well, Ill be honest why im running one. The engine bay is a lot cleaner. I ran a recirc for a long time and it looked very cluttered Once i swapped to a BOV i loved how more simplistic my bay looked.

Also and once again ill be honest. I like the sound, I think its bad ass, i like it just as much as loud fuel pumps and turbo spooling, external waste gates and back fires. I think a bov fits my car perfectly and really completes the sound.

I would like to keep it, my intentions where to go megasquirt and i wouldnt have to worry about it. But the stuff you're doing here is awesome and affordable. So im wondering if i should invest in a quality bov to hopefully mend my dieing issue or if i would be better off buying this stuff and fixing the problems with the tune.

You can load the 93x roms on any 9xx ECU as far as I know; that's why I chose it. I also chose it because if you paid for TLAO's chip (like I did), it's editable in my XDF.

But there's nothing cooler than stalling out your automatic!

is it a v1? (i.e. does it have a big scary picture of an Ostrich?)

Cool. I guess I'll find out next week.

Is it the original Ostrich or the smaller 2.0 that they sell now? I don't know if it makes a difference, but...


Beepee/others: I played with that "Fuel map RPM axis base" scalar on TunerPro. Looks like we can tinker with that(and nothing else needed, right?) to adjust the scale so we can fine tune at higher rpm when using a higher redline? Anyway, I adjusted it to 103, giving me a 550-6775rpm table(36/~6775 redline bin) and saved it. Then I went to ipdown's editor to correct the checksum and just look it over. When I open it up in the LH24 Editor though, the main fuel map's table goes from 1480-6120rpm??? Not 550-6775rpm. The data values for the map are the same, even though the rpm labels are different.

With that being said, I went and compared the stock 935NA map on TunerPro to LH24 Editor and TP shows the map ranging from 501-6350rpm vs 1600-6240rpm on the Editor.

For what it's worth...?

it's a version 1, but no big picture of an ostrich. just an ominous large black case with a ribbon cable.

It's mega-old then: http://support.moates.net/2008/09/11...h-10-overview/

Can't fine anything about address tracing in the 1.0 docs either :-/ It only runs at 115,200 baud so it may not be fast enough for it...

[Hagar17]

so... what cars have 9xx ECUs?

certain year / models?

The released version of LH2.4 Studio is old. It doesn't use the correct (log based) formula for RPM. It just multiplies by 40. (it's actually selectable in one of the menus IIRC)

With tracing on watch any of the RPM tables while you rev the motor; it's way off. I'm sure the new version will be fixed.

Gotcha. I knew it was old but didn't know the RPM was off. I haven't run it hooked up to the car yet because my Ostrich doesn't arrive until Monday!

That being said, are you saying I should be able to open up my 951 bins with your 935 xdf? Because so far I haven't been able to, they seem to pull from different locations, or something. If I load a stock 951 bin, the main fuel map is filled with 255s and the load/rpm axis' are all sorts of crazy -1000s numbers going "up" to a positive number when nearing low rpm and higher loads on each axis.

Ok, done playing for tonight, headed home...

sounds about right. I seem to recall this thing kicking around back in 03-04.

Looks like it's a crap shoot from years 90-94. Seems like most of the 95 and up cars had them.

I'd just go look; it literally takes about the same amount of time as it would to find your car in the list.

the xdf has to match the rom version for TP, otherwise its looking in the wrong places and grabbing the wrong information.

I'd think most if not all Efan cars would be 9xx ecus eh? and some of the non-efan cars as well

Did you try to change any values? The revlimit is a safe one with immediate results.

Not being able to trace definitely limits your tuning capability though. Even if you put a gauge on the AMM signal, it's non linear... and the ECU does crazy things to the AMM signal anyhow.

Makes sense to me.

[linuxman51]

yeah I fiddled around with a few things, burned another rom to it while it was running, that sort of shenanigan type stuff. Without a wideband there wasn't much I was planning on doing anyway, I just wanted to see if it'd do the other stuff. I might try and track down a used one
