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

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.

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

yep, vems round is a great product.

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

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.

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

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.
