VEMS Install on my verde - Page 5

yea the TPS works fine that is in the pic above. my oil leak is a bad valve guide. I do not think the gaskit/'O' ring is a problem. I think I will keep the oil to the head the way it is. I somehow think external oil lines will crack and be a real pain. I forgot the 'O' once on my old motor and it still did not leak. I thought it was but it was the sender leaking and knowing I left out the 'O' I thought that was the leak. as a rule my alfas do not leak.
there is kinda a dirty oily pan and trany but no drops on the ground.
it seem every time I have got a leak that drips it turns out to be a leak in one of the 2 oil senders and a easy fix. all the spots in my driveway are from changing the oil filter where the oil just runs everywhere.

tomp,

Is this really a problem even with the 3.0 heads? I thought the problem was with the older multi-piece headgaskets and shankle sold those external oil feed lines. Or am I talking about something different here? I've never had problems with the newer single piece headgaskets.

Ive heard its a problem but have a sample of one that Im basing this on. My verde weeps oil at the head gasket. It had a valve job a couple of years ago before I got it so who knows maybe someone left the orings out. The external lines should provide oil to the cams faster than the drillings though. Might be good with high lift cam and big springs.

This took a while but I got around to making my air box.
I used my old box and just added some new steel welded it up. And made some round pipes (3 of them) 2 small and one big one. The small ones I bent around a sockit then welded the seam. The big one I use a 3in puch, a soda can might have worked too.
I found some U shaped hose at the local auto store
The smaller one goes to the oil separator
The next one goes to the IAC (idel air control valve) I have a 'T' and I have the very small tube for the charcoal canister.

Sly, did you ever get the knock sensor to work? I've heard knock sensors are hard to get working with a 12 Valve Alfa?

Did you get my PM??

Thanks

Grant,

Why didn't you get VEMS? Looks good spec wise. If megasquirt you could get from Mike Harris (owner of alfaGTV6.com) as he had a fully working unit and removed it. Software wise VEMS and megasquirt both look promising.

Grant · #67 (**permalink**) 10-27-2007, 12:03 PM

I never heard why he removed it. I kinda asked on the GTV6 BB but didn't get an answer. Do you know why he ditched it? I thought it was throttle response but a few others said throttle response with MS is fine. But at this rate, I'm only out $157 if I have to throw away MS. VEMS is going to be like 650 in Euros I think? Plus shipping?

I think so, he didn't quite get it right with the throttle response and went back to L-Jet. IMHO you need both TPS and an air flow,mass or pressure sensing device to have a good driving experience. Almost all manufacturers have both devices, I'm not sure I believe that having just one (either TPS or AFM/MAF/MAP) will make it just as good as OEM.

See if there is the correct C code which has TPS/MAP blend for MS. There must be those around, lots of users of MSI/II on alfagtv6.com and I see them mounting the pot type TPS on the throttle body.

VEMS's specs looks quite impressive (EGT, knock, wideband O2 all intergrated, option for LCD display), and their software looks nice. If I was looking for a sub $1K system I would look at this first.

When you install it let me know, I want to see how easy is it to tune it. We can compare it to Autronic's tunability and software. I'm having my upgraded in a few days (new firmware).

The way I tuned is to have the WBO² working get it to run then let the WBO² do the correcting log it and fix the MAP.
megatune has some autotune thing in it but I never could figure it out. And just useing the logs I seem to get the map very very good after just a few passes.

I like to use megalogviewer I changed the math in the profile to just look at the offsets and I can use it to calc the maps with the log.
I have not tested the knock I have it mounted but I never did a recording. I guess I could just try it and calc what the freq. it should be based on bore size.

Hey Sly,
Have you had it through CA emission testing? Curious how easy it was to get to pass emissions.
I'm also curious to know how the knock sensing works out. Where did you mount the knock sensor(s)? One or two?

I mounted 2 look back in this thread I posted pics of it.
