knock, knock who's going to tune my s2 for me?

Hey Shane,

probably should have said I was staying motronic at the outset.

Ah for goodness sake !





Looking forward to the meet on the 01/12/10 for a good slagging, both ways.

I and many others have been using the wideband in the location of the narrowband sensor and have not had any issues.

[s2_wot]

My understanding of the wideband sensor from a thread on here is that they are susceptible to damage by heat and therefore the bung should be further down in the downpipe, before the cats. Also they have a specific orientation to prevent moisture damage from condensation when the engine is switched off.

That leads me to believe that the narrowband should be in the stock location (m18 thread), the EGT somewhere in the same region (1/8" NPT thread) and the wideband down further down (m18 thread). I'll check those thread sizes later and repost if I'm wrong.

What I'm looking for (it seems) is a datalogger and display that will record and live report these other pieces of information. This will allow me to produce graphs and with the help of others, be they paid tuners or experienced others, I'll be able to fine tune the motronic based on what the engine in producing out the exhaust. CSI style. The display will be useful so I can see the EGT and if it's too hot back off, likewise if the AFR is outside what it should be I can back off too.

My simple mind tells me that the zeitronix ZT-2 with LCD display clearly shows 4 concurrent readings. I don't have a boost gauge yet anyway so AFR, Boost, EGT and fuel pressure would be my choice and datalog the IAT then just for giggles. I don't have to buy all the toys day 1 but rather when I have money for add ons. Anybody here using this equipment?

More research needed. But getting the bungs into the downpipe is in many ways the 1st step. More news on that later.

The other thing is that if I just go for a mildly tuned RS2 setup I won't need any of this stuff, so put in context I'll take the 1st part of Rocco's advise now and worry about the second part later.

All good input, probably should have said I was staying motronic at the outset.

Vems Round definitely looks interesting. If I didn't have the Innovate setup I would most certainly look into that solution.

[a4kquattro]

yep, vems round is a great product.

[mcandmar]

Ok i'm sold, i'll add that to my shopping list

That is an interesting bit of kit, but i'm a little confused on these wide band sensors. Can they give a narrowband output to drive the ECU or do you have to fit both O2 sensors into the downpipe?

Also with the EGT sensor, can you thread them into the CO takeoff on the downpipe or did you have to weld another mounting point for it?

SLC DIY and VEMS Round can.
AEM UEGO can't. At least not properly.

I am running the wideband sensor in the location of the narrowband and using the simulated output for the ECU. Everything works fine.

Looking at the picture I realized, that I should have posted it this way for Shane:

[macspring]

Howdy,

As has been appreciated, we are all on the same side on this forum, it's just that some people see things diferently, once we all remember that it will still be happy families.

Hope Shane now knows what to use !

I'll get my coats...

[Jonnybravo]

No worries.

[prj]

I think he got that

Play nice

Fair enough.
@Jonnybravo, sorry if you got offended by what I said.

[Sonic]

It's not about offence at all. Just try to read and comprehend what I write.

You don't leave things do you.

If I choose to you a AEM I welcome to do so.

Of course, but this thread is not about you and not about aftermarket ECU's.

Its a bit like nagging at people for using 3 grands worth of Motec ecu when one thats 1/3 price does the same, personal preference.

No, it's saying that an AEM UEGO is fairly useless for mapping motronic, which this thread is about. Which I have said three times now.

I don't map engines, I'll leave that to people who know what their doing, I'll monitor things though and thats why I use a AEM.

For the fourth time, read the thread title :/
If you don't map engines, why are you saying which WBO2 to install for mapping? I map motronic every day...

If I knew it was going to cause such offence to you I'll not bother replying in future

It's not about offence at all. Just try to read and comprehend what I write.

Also, I said I'd post a pic of how the SLC looks on my car. A phone pic will have to do:

It's attached simply using double sided tape and can be removed at any time.
The cable could be made less visible, but I was too lazy to take apart the dash just for that.

The USB cable goes in at the back. Not attached in this picture.

The benefit is, that you don't have to get one of those starship enteprise pillars.
